Technical Field

The invention relates to a matching type facial mask manufacturing system and a manufacturing method.

Background

The mask is one of cosmetics that can supply various nutrients, moisture, and the like to the skin using a mask manufactured to be matched to the face shape, and generally has a flat shape as a whole to be attached to the face of a user, and holes may be perforated at positions corresponding to the eyes and mouth of the user. Manufacturers produce a lot of facial masks to be supplied to the market using an automated apparatus capable of producing a lot of facial masks in a short time by continuously performing a series of processes of impregnating functional substances on raw materials such as non-woven fabrics, films, etc., cutting the raw materials, packaging, etc.

The mask produced in mass production as described above is expected to provide a certain degree of effect at a relatively low cost and to respond well in the market, but there is a problem that the user cannot use the mask most suitable for his own skin due to the limitation of the mass production system. For example, although some people have a facial mask in which a functional substance for treating acne is impregnated because acne is frequently present on the skin, and some people select a facial mask in which a functional substance having a whitening effect is impregnated, the above-described mass production method cannot meet the needs of individual users.

In order to solve such a problem, a technique has been proposed in which a user can select a functional substance required by the user and adjust the amount of the functional substance to be impregnated.

However, the above-mentioned techniques provide users with freedom to select the kind and amount of the functional material, and do not consider the face shape or skin condition of the users, so that there is a limitation in maximizing the mask effect.

Specifically, although the size of the face, the positions of the eyes, nose, and mouth, the size, shape, and the like are different depending on the user, conventional masks have holes or cut-out portions formed at the same positions corresponding to the eyes, nose, and mouth, and only a sense of discomfort such as a lifting or the like is felt if the mask is actually used.

Further, the skin of the user has a problem that the skin is different from part to part, and the conventional facial mask has a problem that the effect required for each part cannot be obtained at once because the whole facial mask contains the same functional substance.

In order to provide a desired functional substance to each position of the skin of a user by using the mask once, it is necessary to accurately diagnose the skin condition and to grasp to which position the part corresponds accurately on the face of the user.

Detailed Description

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the description of the present invention, a detailed description of a related known structure or function is omitted when it is determined that the gist of the present invention may be confused.

Fig. 1 is a diagram showing a configuration of a matching type mask manufacturing system according to an embodiment of the present invention, fig. 2 is a diagram showing a process of generating three-dimensional diagnostic data in a diagnostic part of fig. 1, fig. 3 is a diagram showing an example of a functional substance applying section of the mask manufacturing part of fig. 1, and fig. 4 is a diagram showing an example of a mask provided by the mask manufacturing part of fig. 3.

Referring to fig. 1 to 4, a matched type mask manufacturing system 10 according to an embodiment of the present invention includes: a user information acquisition section 100 that collects data of a shooting user; a diagnosis unit 200 for generating three-dimensional diagnosis data based on the information collected by the user information acquisition unit 100, and generating shaping (forming) data and a plurality of functional material mapping (mapping) data from the three-dimensional diagnosis data; and a mask manufacturing part 300 which manufactures a mask according to the shaping data and the mapping data provided by the diagnosis part 200.

In the present embodiment, the mask means a skin beauty tool containing a predetermined functional substance, which is applied to the face of a user to allow the functional substance to directly act on the skin. The mask manufacturing system 10 may be implemented as one apparatus in which the respective components are structurally connected to each other, or may be implemented in a form in which the components are partially structurally separated and connected to each other by data communication.

In the present example, the mask film is formed by coating the functional substance on the base material B, but the concept of the present invention is not limited to this. For example, the mask may be formed by applying a hydrogel containing a functional substance, excluding the substrate B such as a nonwoven fabric. At this time, the shaping data in the present example can be understood as information necessary for realizing the shape of the mask by applying the hydrogel containing the functional substance. The base material B of the mask may be formed of a hydrogel material, and in this case, the forming data may include information such as an application route for forming the base material B by applying the hydrogel material.

The user information acquisition section 100 collects data of photographing the face of the user, and can receive photographing data photographed by the photographing section 20 that can be provided separately. At this time, the user information acquiring part 100 may be a data receiving device or a communication module provided to be able to communicate with the photographing part 20 to be able to receive data, and may be a constituent element of the diagnosing part 200 according to an embodiment. For example, the user information acquisition unit 100 may be an application or program that is installed in a predetermined electronic device such as a PC or a notebook computer provided as the diagnosis unit 200 and can receive the shot data by wired/wireless communication with the shooting unit 20. Here, the photographing data collected by the photographing part 20 may include a plurality of images including a plurality of reference points among the reference points that have been set on the face of the user.

In the present embodiment, the reference point is a position that can be applied as a mark point (Landmark) in the face of the user, and may be understood as a position of a specific pixel or voxel in the captured data. For example, the reference points may be the ends of the user's eyes, the ends of the eyebrows, the lips, the widest width of the nostrils, the beginning and end of the ears, and the like. In fig. 2, reference points are shown as examples, where the two side end points of the right eye and one side end point of the lip of the user are respectively marked as P1, P2, and P3. However, the point that can be applied as the reference point may be differently set according to the embodiment, and the concept of the present invention is not limited by the kind of the reference point.

In addition, in order to match the diagnostic data when generating the three-dimensional diagnostic data, identification codes are given to the respective reference points, and the data may be stored in the database unit 280 and shared by the three-dimensional model generating unit 210, the skin condition diagnosing unit 220, the three-dimensional diagnostic data generating unit 230, and the like.

In the present embodiment, the imaging unit 20 may be a separate mobile terminal equipped with a camera, such as a smartphone or a tablet PC, which is carried by a user, a cosmetic seller, or the like, or a camera, a three-dimensional scanner, or the like, which is disposed in a shop or the like equipped with the matching type mask manufacturing system 10. The type of the imaging unit 20 is not limited as long as it can acquire an image of the face of the user and collect basic data for generating a three-dimensional model and skin diagnosis data. In the present embodiment, it is shown by way of example that a smartphone is provided as the photographing section 20.

At this time, the photographing data provided by the photographing part 20 may be a video. In the present embodiment, the video may be understood as a set of still images continuously photographed at a set frame interval, and the frame image may be understood as meaning a still image at a certain instant. For example, a 60-frame video is a set of frame images continuously captured at 1/60-second intervals. In this case, the diagnostic unit 200 extracts an appropriate image from a plurality of frame images constituting the video and applies the extracted image to three-dimensional model generation and skin diagnosis.

In order to diagnose the skin condition of the entire face of the user, the imaging section 20 may provide data for imaging the face of the user at a predetermined angle or more in both directions on a front (fig. 2(a)) basis. In order to photograph over a predetermined angle range, the photographing part 20 may display a guide to the operator through a display or the like. When the photographing part 20 collects the user's information as a video, the user can generate the photographing data by inputting a video photographing start instruction, moving the camera to the periphery of the face, and inputting a video photographing end instruction, and thus more convenient collection of the photographing data can be achieved. On the other hand, when the shooting data transmitted from the shooting unit 20 does not satisfy the set angle range, the user information acquiring unit 100 may feed back a signal requesting re-shooting to the shooting unit 20, and the shooting unit 20 may display the signal in voice or video to the operator to perform re-shooting.

In the present embodiment, the video is received from the photographing part 20 as an example, but the inventive concept is not limited thereto. For example, the image capturing section 20 may capture the face of the user at a plurality of specific angles and then transmit a plurality of captured pictures to the user information acquiring section 100. When the received shooting data cannot satisfy the set angle range in this case as well, the user information acquisition section 100 feeds back a signal requesting re-shooting to the shooting section 20.

In addition, in the present embodiment, the case where the photographing part 20 is additionally provided and the user information acquiring part 100 receives the data photographed by the photographing part 20 is taken as an example for explanation, but the concept of the present invention is not limited thereto. For example, the user information acquiring unit 100 may include an imaging unit 20 such as a camera that can directly collect imaging data of the user. That is, the imaging unit 20 may be a component of the user information acquiring unit 100, and in this case, the user information acquiring unit 100 may correspond to a smartphone.

Upon receiving the imaging data from the imaging unit 20, the diagnostic unit 200 generates three-dimensional diagnostic data, shaping data, and mapping data for the user by applying the imaging data.

In the present embodiment, the three-dimensional diagnostic data may be data representing skin characteristic information, which is a result of diagnosing the skin of the user, on a three-dimensional model in which the face of the user is shaped, and the physical form of the three-dimensional diagnostic data may be a file that can be stereoscopically represented by a predetermined image tool on a computer. For example, the imaging tool may be a commercially available program such as AUTOCAD or 3DS MAX, and the three-dimensional diagnostic data may be a file that can be read by AUTOCAD or 3DS MAX. Such three-dimensional diagnostic data may be generated by a user modifying a three-dimensional model representing the appearance of the user's face based on the skin diagnostic data, as will be described in more detail below.

In the present embodiment, the forming (shaping) data is understood to be information on the positions, sizes, and shapes of the plurality of cut-out portions 32 to be formed in the mask base material B in order to bring the mask film 30 into close contact with the face of the user, and the forming means a process of forming the cut-out portions in the mask base material B. In this case, when the mask is not formed of a planar material but has a three-dimensional shape, the forming data corresponding thereto may be formed, and the corresponding forming may be realized.

In the present embodiment, the position of a certain structure (e.g., the cut-out portion 32) may be understood as a position of a certain feature point included in the structure or a set of positions of these points when the structure is represented in two dimensions or three dimensions. For example, the position of a certain structure may be understood as the position of a pixel (pixel) or voxel (voxel) or a set thereof comprised at a point of the structure. In addition, the size of a structure may be understood as a concept including the width, amplitude, area, or volume that the structure represents, and the shape of a structure may be understood as the shape of the structure represented in two or three dimensions. The size or shape of such a structure may be embodied in units of pixels or voxels.

In the present embodiment, the mapping data is information as to which functional substance is applied to what extent at which position of the base material B of the mask film, and may include data relating to the type of functional substance to be applied, the application position, the application range, and the application amount, and may additionally include information as to the application order, the application speed, and the application path of the functional substance.

Specifically, the diagnostic component 200 includes: a three-dimensional model generation unit 210 that generates a three-dimensional model corresponding to the face shape of the user from the imaging data; a skin condition diagnosis unit 220 for diagnosing the skin condition of the user based on the imaging data; a three-dimensional diagnostic data generation unit 230 for generating three-dimensional diagnostic data by reflecting the skin diagnostic result on the generated three-dimensional model; a shaping data generating section 240 for generating shaping data for cutting the mask base material B; the functional substance mapping unit 250 generates mapping data for applying a functional substance to the mask base material B. In addition, the diagnostic component 200 may include: a display unit 260 capable of outputting video information so that the user can confirm the above-described procedure; a user input unit 270 for allowing a user to input a predetermined command or data generated by processing; a database unit 280 capable of storing the imaging data, the three-dimensional diagnostic data, the shaping data, the mapping data, and the like; and a communication part 290 providing a wired/wireless interface to enable data communication with an external device, the user information acquisition part 100, or the mask manufacturing part 300.

The three-dimensional model generation unit 210 may generate a three-dimensional model in which the face of the user is shaped based on the captured data supplied from the user information acquisition unit 100. In order to generate a three-dimensional model, at least two or more images may be applied, and when shot data is provided in the form of a video as in the present embodiment, a part of a plurality of frame images included in the video may be extracted and applied by the three-dimensional model generating unit 210. For example, the three-dimensional model generating unit 210 may perform a process of selecting a part of the image including three or more reference points in one frame image to generate a three-dimensional model, and applying another part of the image including three or more reference points to verify and repair the generated model.

On the other hand, the three-dimensional model generated by the three-dimensional model generation unit 210 includes coordinate information of a reference point on the three-dimensional model together with data for representing a three-dimensional shape. For example, the three-dimensional model generated by the three-dimensional model generating unit 210 may have a three-dimensional shape as shown in fig. 2(a), and may include three-dimensional coordinate information of P1, P2, and P3 on the three-dimensional model.

In order to generate three-dimensional diagnostic data, the skin condition diagnosing unit 220 can diagnose the skin condition from the two-dimensional image and grasp the type, position, size, shape, and the like of skin characteristics that can be improved by the functional substance that can be applied. In the present embodiment, the two-dimensional image corresponds to a three-dimensional stereo model, and can be understood as a general plane image.

In the present embodiment, the skin characteristics of the user can be improved by the functional substance impregnated in the mask, and can include skin characteristics having a three-dimensional uneven shape and skin characteristics accompanied by color change. Specifically, the skin having a three-dimensional concavo-convex shape has wrinkles, pores, scars, scabies, and the like, and the skin has a color change accompanied by precipitation of pigment, hot flashes, skin color, and the like.

The skin condition diagnosing unit 220 may select a part of the plurality of images included in the captured data to grasp the skin characteristic information included in the image. At this time, the image selected by the skin condition diagnosing section 220 may be an image including at least three or more reference points in a plurality of frame images constituting the video. That is, the skin condition diagnosis unit 220 calculates the number of reference points included in each frame image, and determines whether or not the frame image is selected for skin characteristic diagnosis.

In the present embodiment, the skin condition diagnosing unit 220 directly selects an image for detecting skin characteristics, but according to the present embodiment, the present invention may be applied by receiving a frame image for a three-dimensional model from the three-dimensional model generating unit 210. Of course, according to the embodiment, the skin condition diagnosing unit 220 may first analyze the reference point information such as the type and position of the reference point included in the image, and the three-dimensional model generating unit 210 may receive the reference point information and apply it to the three-dimensional model generation. That is, either the skin condition diagnosing unit 220 or the three-dimensional model generating unit 210 may analyze the reference point information included in the image of the captured data, and the other may receive and use the information.

In the present embodiment, the reason why the frame image including at least three or more reference points is selected is to accurately define the position of the skin characteristic by the distance from the three reference points, and in some cases, a larger number of reference points may be used as a reference. As an example, the skin condition diagnosis unit 220 may select one of images including both eyes, a nose, a lip, and one ear, which can be set as reference points, in one frame image, as shown in the left diagram of fig. 2 (b).

In this case, the skin condition diagnosis unit 220 may set an area to be determined for skin characteristics in the image selected in this manner as shown in the left side view of fig. 2 (b) and display the area to the user via the display unit 260.

The skin condition diagnosis unit 220 determines the type, position, size, and shape of the skin characteristic on the selected image, and generates diagnosis data. For example, the skin condition diagnosis unit 220 may determine the position, size, shape, and the like of skin characteristics having a three-dimensional shape such as the depth, width, length, and number of wrinkles, the depth, width, and number of pores, the area and color of pigmentation, the area and color of hot flashes, and the color change. The judged skin characteristics may be displayed in additive colors as in the black portion in the right-hand graph of fig. 2 (b) to enable the user to clearly distinguish from the own face.

At this time, the position of the skin characteristic calculated by the skin condition diagnosing section 220 may be calculated as a relative position to the reference point. Of course, the reference points may be reference points generated in the three-dimensional model, and may actually be paired with reference points generated in the three-dimensional model in a ratio of 1: 1.

For example, the position of the point where the skin characteristic appears may be calculated as two-dimensional coordinates with reference to the reference point, or as a distance from the reference point. In the present embodiment, the description will be given taking an example in which the positions of points at which skin characteristics appear are each expressed as the distance from a reference point. For example, the skin condition diagnosing section 220 may grasp the position of one point of the skin characteristic displayed as a black area in (b) of fig. 2 as distances d1 from P1, d2 from P2, and d3 from P3, and may define the accurate position of one point of the skin characteristic according to the distances from the three reference points.

In this case, when the skin characteristic has a predetermined area and can be displayed as a plurality of pixels or voxels on the image, the skin condition diagnosis unit 220 may calculate and store the above-described positional information for each pixel.

The skin condition diagnosing unit 220 may store the index (index) of the frame image for diagnosing the skin condition, the type and position of the reference point included in the frame image, and the type, position, size, and shape of the skin characteristic extracted from the frame image in the database unit 280 or provide the information to the three-dimensional diagnostic data generating unit 230.

On the other hand, the three-dimensional model generated by the three-dimensional model generating unit 210 is a three-dimensional shape formed based on a captured image, but is limited in embodying the specific skin characteristics of the user. Specifically, in the case of skin characteristics having a three-dimensional uneven shape such as wrinkles, pores, scars, and scabies, the three-dimensional uneven shape cannot be accurately reflected on the three-dimensional model because the skin characteristics have a very small size. In addition, when skin characteristics accompanied by color change such as pigmentation, hot flush, skin color, etc., they cannot be simply reflected on the three-dimensional model. In this case, although the skin characteristics on the frame image which is two-dimensionally displayed by Texture Mapping (Texture Mapping) can be overlaid on the stereoscopic image, it is not different from simply applying colors to the stereoscopic shape, and it is difficult to accurately determine the skin state.

In contrast, in the present embodiment, in order to provide a matching type mask that can accurately correspond to the face shape and skin condition of the user, three-dimensional diagnostic data is generated and applied to the manufacture of the mask. However, the concept of the present invention is not limited to the application of three-dimensional diagnostic data, and in another embodiment, a method applied to the manufacture of a mask by directly measuring the skin state from a three-dimensional model may also be used.

The three-dimensional diagnostic data generator 230 generates three-dimensional diagnostic data by combining the diagnostic data generated by the skin condition diagnostic unit 220 with the three-dimensional model generated by the three-dimensional model generator 210. Specifically, the three-dimensional diagnostic data generation unit 230 may pair the positions of the reference points included in the three-dimensional model with the positions of the reference points received from the skin condition diagnosis unit 220, and present the skin characteristic information on the three-dimensional model with the positions of the paired reference points as references.

At this time, the position of the skin characteristic measured by the skin condition diagnosing unit 220 is a relative position to the reference point in two dimensions, the three-dimensional model is presented in three-dimensional coordinates, and the three-dimensional diagnostic data generating unit 230 may convert the position information of the skin characteristic into correspondence with the three-dimensional model so that the position of the skin characteristic generated by the skin condition diagnosing unit 220 can be presented on the three-dimensional model. Of course, the three-dimensional model data may be converted into two dimensions and paired.

For example, in the skin diagnosis screen ((b) of fig. 2), the distances from the reference points P1, P2, and P3 to one point of the skin characteristics are measured as d1, d2, and d3, respectively, but are distances that do not reflect the three-dimensional shape of the face of the user. Thus, the three-dimensional diagnostic data generator 230 projects the three-dimensional model onto a plane, then sets the position of one point of the skin characteristic by using d1, d2, and d3, and projects the set position of one point of the skin characteristic onto the three-dimensional model again, thereby accurately matching the position of one point of the skin characteristic onto the three-dimensional model. In this case, the direction in which the three-dimensional model is projected onto the plane may be determined as the direction of the three-dimensional model corresponding to the frame image for diagnosing the skin condition received from the skin condition diagnosing unit 220, and the three-dimensional diagnostic data generating unit 230 may perform rotation, movement, and size conversion of the three-dimensional model in order to match the three-dimensional model with the face shape presented in the frame image.

As another example, the three-dimensional diagnostic data generator 230 may parameterize (parameterize) the three-dimensional model to form a Texture Mesh (Texture Mesh) and set the pairs of reference points and the positions of the skin characteristics in correspondence with the frame images used by the skin state diagnostic unit 220.

Various known methods such as three-dimensional Affine Transformation (3D affinity Based Landmark) Based on a marker point can be applied to the method of setting the position of the feature portion on the two-dimensional image on the three-dimensional model, and detailed description thereof is omitted.

The three-dimensional diagnostic data generator 230 may modify the three-dimensional model to present the skin characteristics after determining the position of the skin characteristics on the three-dimensional model.

In particular, the three-dimensional model may be directly modified to present skin characteristics having a stereoscopic shape. For example, the skin condition diagnosis unit 200 may transmit information such as the height, area, number, and position of the scabies to the three-dimensional diagnosis data generation unit 230, and the three-dimensional diagnosis data generation unit 230 may generate a three-dimensional model that is added to the generated three-dimensional model in accordance with each three-dimensional individual of the scabies. In the present embodiment, a method of newly generating a three-dimensional individual corresponding to skin characteristics having a three-dimensional shape and adding the three-dimensional individual will be described as an example, but various known methods of modifying a three-dimensional model may be used in addition to this method.

In addition, the three-dimensional diagnostic data generation unit 230 may present the skin characteristics accompanying the color change by modifying the three-dimensional model. For example, the skin condition diagnosis unit 200 may transmit information such as the position, area, and shape of the region where pigmentation occurs to the three-dimensional diagnosis data generation unit 230, and the three-dimensional diagnosis data generation unit 230 may change expression (Rendering) information of a three-dimensional model of the region where pigmentation occurs, generate a new two-dimensional individual to be added to the three-dimensional model, or extract the region from the frame image to perform Texture Mapping (Texture Mapping). As in the case of skin characteristics having a three-dimensional shape, various known methods can be used other than the method of reflecting skin characteristics associated with color changes to a three-dimensional model.

In this way, the skin characteristics of the three-dimensional concave-convex shape and the skin characteristics accompanying the change in darkness are presented in the three-dimensional model in different ways, thereby enabling the user to more intuitively recognize the skin characteristics of the user.

In the present embodiment, as shown in fig. 2, the two end points of the right eye of the user and one end point of the lips are exemplified as the reference points P1, P2, and P3, and after diagnosing the pigmentation region located in the right cheek of the user, it is presented by modifying the expression of the three-dimensional model. The three-dimensional diagnostic data thus generated can be visually presented through the display unit 260 so that the user can confirm the skin condition of himself.

The three-dimensional diagnostic data generator 230 reflects the skin condition diagnosed by the skin condition diagnosing unit 220 to a three-dimensional model of a three-dimensional shape, and can generate three-dimensional diagnostic data that accurately reflects the face shape and the skin condition of the user.

On the other hand, the shaping data generator 240 generates shaping data for cutting and incising the mask base material B by using the three-dimensional diagnostic data generated by the three-dimensional diagnostic data generator 230. Specifically, the shaping data generating unit 240 calculates shaping data including the position, size, and shape information of the cut-out portion 32 corresponding to the eyes, nose, and mouth of the user to be formed on the mask base material B or for improving the attachment of the mask in consideration of the face shape of the user, by applying the three-dimensional diagnostic data. For example, the shaping data may include information on the size, shape, and position of holes formed in the mask base material B at positions corresponding to the eyes and mouth of the user, slits formed to correspond to the contour, shape, and height of the nose of the user, slits formed in a partial region of the mask base material B to overlap or split in order to make the mask base material B follow the size of the face of the user, shape attachment to the face of the user, and the like. In particular, the shaping data may be variously set according to specific characteristics or skin characteristics of the face shape included in the three-dimensional diagnostic data, so that the mask is more thoroughly attached to the user's face, preventing a turn-up phenomenon, while being able to maximally bring out the effect of the functional substance.

Such shaping data may be generated by the following process: a process of calculating the range of the incision region set for the eyes, mouth, etc.; and a process of extracting a Mesh or Polygon (Polygon) to set a cut-out range in an area overlapping or broken above a set reference or exceeding a set plane standard in the process of converting the three-dimensional diagnostic data into a (unwrap) plane.

In the present embodiment, the example in which the shaping data generating unit 240 generates shaping data using three-dimensional diagnostic data is described, but the concept of the present invention is not limited thereto, and the shaping data generating unit 240 may generate shaping data using a three-dimensional model.

The functional substance mapping section 250 generates mapping data including the type of functional substance to be applied to the mask base material B, the application position of the functional substance, the application range of the functional substance, and the application amount of the functional substance. Specifically, the database unit 280 stores the skin characteristics that can be diagnosed by the skin condition diagnosis unit 220 and the combination ratio of any one functional substance or a plurality of functional substances that matches each skin characteristic or the quantitative or qualitative characteristic of the skin characteristic. For example, the database unit 280 may store the amount, concentration, and the like of the functional substance to be applied according to the degree of pigmentation. The functional substance mapping unit 250 may read the functional substance to be applied to the mask base material B according to the skin characteristics, included in the three-dimensional diagnostic data, from the database unit 280 to generate the mapping data. Of course, the functional substance mapping unit 250 may perform a predetermined operation based on the values stored in the database unit 280 to generate mapping data such as the amount, concentration, and combination ratio of the functional substance. In addition, when it is diagnosed that a plurality of skin properties are present at any one site, a plurality of functional substances may be applied to the site.

The functional substance mapping unit 250 may set a position and a range in which the selected plurality of functional substances are applied to the mask base material B according to the position, size, and shape of the skin characteristics included in the three-dimensional diagnostic data. Therefore, the functional substance mapping unit 250 can convert the three-dimensional diagnostic data to set the position of the skin characteristic mapped on the mask base material B to the application position and range of the corresponding functional substance by conversion, as in the above-described shaping data generating unit 240.

The mapping data may further include the coating order, coating path, coating speed, etc. of the functional material, and the functional material mapping unit 250 may calculate the data optimized for the user based on the three-dimensional diagnostic data. For example, the functional material mapping unit 250 may optimize the diameter of the nozzles 336a, 336b, and 336c and the moving speed of the linear motors 332, 334, and 335 according to the viscosity of the functional material. Here, the coating path may be set to be capable of coating the coating area discharged according to the diagnosis result in the shortest time.

On the other hand, the diagnostic unit 200 can provide the user with the processing procedure, the processing result, and the like of the three-dimensional model generation unit 210, the skin condition diagnosis unit 220, the three-dimensional diagnosis data generation unit 230, the shaping data generation unit 240, and the functional substance mapping unit 250 through the display unit 260. In this case, the user may feedback or directly modify the generated three-dimensional model, skin condition diagnosis data, three-dimensional diagnosis data, shaping data, and mapping data by operating the user input unit 270 including a user interface device such as a mouse or a keyboard.

The diagnostic unit 200 may store the results of the three-dimensional diagnostic data generated as described above in the database unit 280 and perform history management in accordance with the user. Thus, the user can confirm how the skin of the user is improved by using the matching type mask, and the satisfaction can be improved.

The diagnosis unit 200 may not only perform data communication with the user information acquisition unit 100 and the mask manufacturing unit 300 through the communication unit 290, but also update the user information, basic data such as an algorithm for generating the data, functional material information, and the like from a server of a mask manufacturer, and may share the data generation result or provide the generation result to a smartphone, an SNS account, and the like of the user.

In another aspect, the mask making part 300 may include: a transfer portion 310 for receiving the surface film substrate B and transferring the same along a predetermined path; a forming section 320 for processing the mask base material B based on the forming data; a functional substance application unit 330 that applies a functional substance to the mask base material B based on the mapping data; and a cooling unit 340 for cooling the functional material applied to the mask base material B. In this embodiment, a material having a planar shape such as a nonwoven fabric or a film is provided as the mask base material B.

The transfer unit 310 may repeatedly perform the transfer and standby processes in consideration of the time required for processing in each component, by moving the mask sheet 30 so that the mask sheet base material B, which may be continuously or discontinuously supplied, passes through the forming unit 320, the functional material application unit 330, and the cooling unit 340 and is processed and discharged. For example, the transfer unit 310 may be a conveyor belt and a driving device for driving the conveyor belt. The mask base material B may be supplied to the transfer section 310 from a predetermined mask base material B supply means. For example, the mask base material B supplying member may be a member in which a raw material such as a nonwoven fabric is wound around a winding drum, and the raw material may be transferred to a conveyor of the transfer unit 310, cut into a circular shape by a predetermined cutting device, and supplied to the forming unit 320.

The shaping unit 320 receives the shaping data generated by the shaping data generating unit 240 of the diagnostic member 200, and processes the cut-out portion 32 in the mask base material B. To this end, the forming part 320 may include: cutting members such as a cutter and a puncher capable of cutting the section film substrate B; and a driving part capable of moving the position of the cutting part and performing cutting.

The functional substance applying unit 330 receives the mapping data generated by the functional substance mapping unit 250 of the diagnostic unit 200, and applies a plurality of functional substances to the mask base material B. For example, the functional substance application unit 330 may apply the functional substance to the mask base material B that is placed on the conveyor belt, i.e., the transfer unit 310 and moves. At this time, the transfer unit 310 may be driven to stop the transfer to form the functional substance application unit 330 when the mask base material B is positioned at the set position.

For example, the mapping data transmitted to the functional substance applying section 330 may include information that three functional substances a, B, and c are sequentially applied from the left side to the right side of the mask base material B with reference to the drawing, and the functional substance applying section 330 sequentially applies the functional substance a, the functional substance B, and the functional substance c according to the mapping data. In this case, the application positions of the functional substances a, b, and c are set in the process of forming the mapping data based on the three-dimensional diagnostic data, and when the user applies the mask thereafter, the functional substances a, b, and c can be accurately located at the positions of the skin properties that can exert their effects.

Specifically, the functional material coating unit 330 may transfer the functional material spray unit 336 in the three-axis direction. For example, the functional substance applying part 330 may include: a first linear motor 332 for transferring the functional material jetting unit 336 in a first direction (left-right direction in the drawing); a second linear motor 334 for transferring the functional material spray part 336 along a second direction (ground direction in the figure) vertical to the first direction; and a third linear motor 335 for transferring the functional material spray part 336 in a third direction (vertical direction in the drawing) perpendicular to the first direction and the second direction. At this time, the first linear motor 332 is fixed to the moving block 335a of the third linear motor 335, the second linear motor 334 is fixed to the moving block 332a of the first linear motor 332, and the functional material injection part 336 is fixed to the moving block 334a of the second linear motor 334, so that the functional material injection part 336 can move in the three-axis direction. In the present embodiment, the functional material coating unit 330 transfers the functional material spraying unit 336 in the three-axis direction as an example, but the concept of the present invention is not limited thereto, and the functional material spraying unit 336 may be transferred in the two-axis direction or in the three-dimensional polar coordinate system.

The functional material jetting unit 336 includes nozzles 336a, 336b, and 336c capable of jetting different functional materials from each other, and a valve capable of adjusting the jetting amount of the functional material is provided inside the functional material jetting unit 336. The nozzles 336a, 336b, and 336c are connected to functional material supply lines 338a, 338b, and 338c, and can receive the functional material from a functional material storage unit (not shown) at a predetermined pressure.

The functional material application unit 330 may control the first linear motor 332, the second linear motor 334, and the third linear motor 335 based on the received map data, and may move the functional material injection unit 336 to a predetermined position and path, and inject the functional material in a predetermined amount and at a predetermined speed in the order of the functional material a, the functional material b, and the functional material c. At this time, the movement of the functional material spray part 336 by the third linear motor 335 is formed when the functional materials are sprayed in a superimposed manner.

When the application of the functional substance is completed, the transfer unit 310 transfers the mask base material B to the cooling unit 340. The cooling unit 340 dries and cools the functional substance applied to the mask base material B to complete the functional substance as a final product, and various known cooling methods such as natural cooling and forced cooling can be used.

The mask 30 thus completed may have an area 34 coated with a functional substance on the mask substrate B, and have two areas 34a, 34B coated with functional substances different from each other according to the mapping data. The two areas 34a, 34b thus coated with substances different from each other correspond to the exact location where the skin characteristics of the user are located through the three-dimensional diagnostic data, and therefore the user can sufficiently obtain the effect of the functional substance.

Further, the mask sheet 30 includes a plurality of cut-out portions 32, and such cut-out portions 32 are also generated based on the three-dimensional diagnostic data, and the mask sheet 30 can be more accurately attached to the face of the user having a three-dimensional shape through the cut-out portions 32, and can prevent the lift-up, whereby the functional substance can be placed at an accurate position.

On the other hand, in the present embodiment, the mask base material B is described as a plane, but the mask base material B may have a three-dimensional shape. For example, the mask manufacturing system 10 may be additionally provided with a three-dimensional printer or the like for manufacturing a three-dimensional shape from a three-dimensional model or three-dimensional diagnostic data, and in this case, the concept of the present invention may be directly applied. In this case, the transfer unit 310 includes a fixing member for accurately holding the position of the mask base material B, and the forming unit 320 and the functional material application unit 330 further include a driving device for three-axis movement.

The operation and effect of the matching type facial mask manufacturing system 10 according to the embodiment of the present invention configured as described above will be described below.

The user who wants to use the matching type mask 30 photographs his/her face with the photographing part 20 to generate photographing data. The photographing data may be video data in which the face of the user is photographed at a predetermined angle to the left and right with a front reference. At this time, the photographing part 20 may provide guidance to the user in order to generate accurate three-dimensional diagnostic data. At this time, the user can easily provide basic data required to manufacture the matching type mask by only an action of simply starting video photographing and moving the photographing part 20 to the periphery of the face.

The photographing data generated by the photographing part 20 is collected by the user information acquiring part 100, and the photographing data may be transferred to the user information acquiring part 100 in wired or wireless communication.

The diagnosis unit 200 receives the image data collected by the user information acquisition unit 100, and the three-dimensional model generation unit 210 generates a three-dimensional model that simulates the appearance of the face of the user by applying the image data. The three-dimensional model may be formed as a file readable with a predetermined image tool and may be viewed to a user through the display part 260. At this time, the three-dimensional model generation unit 210 may select and apply to the three-dimensional model generation a part of the frame images satisfying a predetermined condition among the plurality of frame images included in the received captured data. At this time, the generated three-dimensional model includes position information for each reference point.

The skin condition diagnosing unit 220 of the diagnosing unit 200 can diagnose and extract the skin characteristics of the user from a part of the frame images in the captured data collected by the user information acquiring unit 100. The skin condition diagnosing unit 220 may select a part of the frame images included in the plurality of frame images of the received captured data, which satisfies a predetermined condition, to generate the skin condition diagnostic data, and the frame image used by the skin condition diagnosing unit 220 may be an image used by the three-dimensional model generating unit 210 for generating the three-dimensional model, for example. That is, the skin condition diagnosing unit 220 and the three-dimensional model generating unit 210 can share the selected frame image. In this case, the process of individually selecting the frame images satisfying the predetermined condition by the skin condition diagnosis unit 220 can be omitted, and the result can be generated at a higher speed.

The skin condition diagnosis unit 220 generates diagnosis data including the position, size, shape, and the like of skin characteristics appearing on the skin of the user, and supplies the diagnosis data to the three-dimensional diagnosis data generation unit 230. In this case, the diagnostic data generation by the skin condition diagnosing unit 220 may be performed simultaneously with the three-dimensional model generation by the three-dimensional model generating unit 210, or after the three-dimensional model generation is completed. The skin condition diagnosis unit 220 may view the result of the diagnosis to the user via the display unit 260, and allow the user to confirm information related to the skin characteristics of the user.

The three-dimensional diagnostic data generator 230 applies the diagnostic data generated by the skin condition diagnostic unit 220 to the three-dimensional model generated by the three-dimensional model generator 210 to generate three-dimensional diagnostic data. Specifically, the three-dimensional diagnostic data generation section 230 applies the skin characteristics included in the diagnostic data to the three-dimensional model based on the positions of the reference points of the three-dimensional model. In this case, the position of the skin characteristic may be defined as a relative position such as coordinates and a distance with respect to the reference point, and the three-dimensional diagnostic data generator 230 may pair the reference point included in the three-dimensional model and the reference point of the diagnostic data and then present the skin characteristic on the three-dimensional model according to the relative position of the skin characteristic. The pairing of the reference points and the calculation of the relative positions of the skin characteristics may be performed by either a method of matching the two-dimensional diagnostic data to the D-model or a method of matching the three-dimensional model to the two-dimensional diagnostic data.

The skin characteristics diagnosed by the skin condition diagnosing section 220 generally include skin characteristics having a three-dimensional concavo-convex shape and skin characteristics accompanied by color change, and the three-dimensional diagnostic data generating section 230 enables the skin characteristics to be stereoscopically presented by directly modifying the outer shape of the three-dimensional model for the skin characteristics having the three-dimensional concavo-convex shape, and enables the skin characteristics to be presented by modifying the expression or texture mapping of the three-dimensional model for the skin characteristics accompanied by color change.

The three-dimensional diagnostic data generation unit 230 may provide the three-dimensional diagnostic data to the user through the display unit 260, and the user can confirm the three-dimensional diagnostic data corresponding to the face of the user generated by the diagnostic unit 200. At this time, the user may also modify the three-dimensional diagnostic data through the user input 270. This enables more accurate three-dimensional diagnostic data to be generated.

The three-dimensional diagnostic data thus generated includes not only the three-dimensional shape of the user's face, but also the nature and location of the skin characteristics. Therefore, the mask manufactured using the three-dimensional diagnostic data can not only provide a user with a remarkable feeling of attachment but also enable the functional substance to act at an accurate position.

On the other hand, the shaping data generating unit 240 of the diagnostic part 200 generates shaping data for processing the mask base material B based on the three-dimensional diagnostic data. Specifically, the shaping data includes information on the position, size, and shape of the cut-out portion 32 to be formed on the mask base material B in order to enable the mask 30 to be attached more effectively according to the three-dimensional shape and skin characteristics of the user's face, and the generated shaping data can be transmitted through the mask manufacturing member 300 by the communication unit 290.

The functional substance mapping unit 250 generates mapping data for applying a functional substance to the mask base material B based on the three-dimensional diagnostic data. Specifically, the map data includes information on the type of functional substance to be applied to the mask base material B, the application position, the application range, and the application amount of the functional substance, and the generated map data can be transmitted to the mask making member 300 through the communication unit 290. The functional material mapping unit 250 may generate the mapping data after generating the forming data, and the application position of the functional material in the mapping data may be expressed as a position on the mask base material B after forming. In addition, the mapping data may further include information on the coating speed and the coating path of the functional substance.

On the other hand, the generated three-dimensional diagnostic data may be stored in the database unit 280 for each user using identification information such as a user ID as a key value, and the diagnostic unit 200 may directly inform the user what effect is obtained by using the matching type mask by observing the three-dimensional diagnostic data of a specific user through the display unit 260 according to time.

The mask manufacturing part 300 manufactures the mask 30 using the shaping data and the mapping data received from the diagnosis part 200.

The transfer unit 310 of the mask pack manufacturing unit 300 can transfer the mask pack base material B supplied from the predetermined mask pack base material B supply unit to the forming unit 320, the functional substance applying unit 330, and the cooling unit 340, and can discharge the completed mask pack 30.

The shaping unit 320 processes the mask base 320 based on the shaping data received from the diagnostic member 200. For this, the forming part 320 may be provided with a predetermined cutting member.

The functional substance application unit 330 applies a plurality of functional substances to the formed mask sheet 320 based on the mapping data. In this embodiment, the functional material application unit 330 may transfer the functional material spray unit 336 in the three-axis direction by the first linear motor 332, the second linear motor 334, and the third linear motor 335 to spray the functional material, and the functional material spray unit 336 may be provided with a plurality of nozzles 336a, 336b, and 336c capable of applying different functional materials, thereby applying various functional materials. At this time, the functional substance applying part 330 may also drive only one nozzle at a time or drive a plurality of nozzles at the same time according to the embodiment.

According to the mapping data, the functional substance may be applied to a position corresponding to a position of the skin characteristic of the user, whereby two areas 34a, 34B applied with different functional substances from each other may exist on the mask base material B. The positions of the two regions 34a, 34b can accurately correspond to the positions of the skin characteristics when the user applies the mask to the skin, whereby the user can maximally obtain the effect of the functional substance.

The mask sheet base material B on which the functional substance is completely applied is cooled in the cooling unit 340 to complete the mask sheet 30, and can be transferred by the transfer unit 10 and packaged or discharged.

According to the mask manufacturing system 10 according to the embodiment of the present invention, the three-dimensional diagnostic data is generated in consideration of the three-dimensional face shape of the user, the shaping data is generated, and the mask base material B is processed, so that the matching type mask 30 having improved adhesiveness to the face of the user can be provided.

In addition, the mapping data is formed so that the functional substance can be supplied according to the skin characteristics represented based on the skin diagnosis result and the functional substances different from each other can be applied to the skin characteristics different from each other, so that the treatment effect that the user can obtain from the mask 30 can be improved.

In addition, not only the three-dimensional model can be used to improve the attachment, but also the diagnostic data most accurately matching the actual face and skin of the user can be generated by applying the accurate position, size, and shape of the skin characteristic appearing on the face of the user to the three-dimensional model. Also, since the mask is generated using the shaping data and the mapping data, the effect of the mask 30 and the satisfaction of the user with the mask 30 can be maximized.

On the other hand, as another embodiment of the present invention, the mask 30 includes one or more protrusions on a surface contacting the skin of the user. For this reason, the functional material mapping part 250 may determine a position where a protrusion should be formed, a size of the protrusion, a shape of the protrusion, and a kind of a material for forming the protrusion, and thus the functional material applying part 330 may apply a predetermined material for forming the protrusion. In this case, the protrusions may be formed of the same material as the portions corresponding to the positions where the protrusions are formed in the mask 30, or may be formed of a different material. For example, the functional substance forming the projections and the functional substance forming the portions with the projections may be different from each other. In this case, the substance forming the projection may not be a functional substance, but may be a substance harder than the functional substance around or other parts in contact with the face of the user after hardening. By forming the protrusions in this way, a massage effect can be exerted on the skin of the user, and the satisfaction of the user can be further improved.

Fig. 5 is a sequence diagram illustrating a method of manufacturing a matching type mask according to an embodiment of the present invention.

Referring to fig. 5, in the matching type mask manufacturing method according to an embodiment of the present invention, the photographing data of the face of the user photographed by the photographing part 20 is collected by the user information acquiring part 100 (S100). At this time, the shot data is a video in which the face of the user is shot within a set range, or a plurality of photographs of the face of the user are shot at a set angle.

The three-dimensional model generation unit 210 receives the captured data from the user information acquisition unit 100, generates a three-dimensional model (S210), calculates the three-dimensional position of the reference point from the three-dimensional model, and stores the calculated three-dimensional position (S220).

Then, the skin condition diagnosing unit 220 receives the shot data from the user information acquiring unit 100, and extracts an image of the skin condition to be diagnosed from the shot data (S310). At this time, the image to be diagnosed for the skin state may be a partial frame image of a video, and may be an image including three or more reference points.

The skin condition diagnosing unit 220 calculates the number and positions of reference points included in the extracted image (S320), and diagnoses the skin condition based on a set algorithm (S330). Then, the skin condition diagnosis unit 220 generates diagnosis data including the type, position, size, and shape of the skin characteristic to be diagnosed (S330). At this time, the position of the skin characteristic included in the diagnostic data may be defined as a relative position to the reference point, and the skin condition diagnosing section 220 calculates the relative position of the skin characteristic with the position of the reference point calculated in the step S320 as a reference (S340).

In the present embodiment, the skin condition diagnosing unit 220 extracts an image from captured data and calculates the positions of the reference points included in the image, but may first calculate the types, numbers, positions, and the like of the reference points included in the image and then extract an image of the skin condition to be diagnosed based on the calculation.

In the present embodiment, the skin condition diagnosis unit 220 calculates the position of the reference point in the image selected from the captured data, but the position of the reference point included in the image may be calculated by the three-dimensional model generation unit 210, and the skin condition diagnosis unit 220 may receive the data calculated by the three-dimensional model generation unit 210 and apply the data as the position of the reference point.

Here, the position of the reference point calculated in step S220 may be a three-dimensional position on the three-dimensional model, and the position of the reference point calculated in step S320 may be a two-dimensional position in the planar frame image. In addition, the reference point of the calculated position in the step S220 and the reference point of the calculated position in the step S320 may be substantially represented by 1:1 pairing.

Further, steps S210 to S220 may be referred to as a three-dimensional model generation step (S200), and steps S310 to S340 may be referred to as a diagnostic data generation step (S300).

The three-dimensional diagnostic data generation unit 230 applies the diagnostic data to the three-dimensional model to generate three-dimensional diagnostic data (S400). Specifically, the three-dimensional diagnostic data generation unit 230 pairs a reference point of the three-dimensional model with a reference point included in the diagnostic data, and then presents the relative position of the skin characteristic with respect to the reference point on the three-dimensional model. In this process, in order to apply the relative positions of the skin characteristics, a process of projecting the three-dimensional model to a plane and then restoring may be performed.

The three-dimensional diagnostic data is obtained by presenting skin characteristics to a three-dimensional model in which the face of the user is shaped, and can accurately present the position, size, and shape of the skin characteristics appearing on the face of the user, and can accurately generate the shaping data and the functional material mapping data as a user matching type.

Specifically, the shaping data generating section 240 generates shaping data for forming the cut-out portion in the mask base material B using the three-dimensional diagnostic data (S500). At this time, the forming data may include information on a position, a size, a shape of the cut-out portion, and the cut-out portion may include: holes corresponding to the positions of eyes and mouths; a slit formed to follow the three-dimensional shape of the nose or face to improve the attachment.

The functional substance mapping unit 250 generates mapping data of the functional substance to be applied to the mask base material B using the three-dimensional diagnostic data (S600). In this case, the map data is data for applying the corresponding functional substance according to the type, position, size, and shape of the skin characteristic to be diagnosed, and may include information on the type, application position, application range, application amount, application speed, and application path of the functional substance to be applied to the mask base material B.

The generated shaping data and mapping data are transmitted from the diagnosis part 200 to the mask manufacturing part 300, and the mask manufacturing part 300 shapes the mask base material B based on the received information, and applies a functional substance to the mask base material B, thereby manufacturing a matching type mask (S700).
