Technical Field

The invention relates to the technical field of printing, in particular to a method, a device, equipment and a medium for generating identifiable points by printing, a printed product, a position identification method and an information acquisition method.

Background

In production life, people often need to acquire a specific position on the surface of an object. For example, in the process of processing the component, a processing position on the surface of the component needs to be found first, and then a hole, a groove and the like are processed at the processing position; in the touch screen technology and the sliding unlocking technology, the information corresponding to the position is obtained by obtaining the touch screen position, so that the subsequent operation is performed.

With the continuous development of the technology, the position of the surface of an object, which needs to be acquired by people, is more accurate and faster. In order to obtain more and finer positions on the surface of an object, it is conceivable to identify the position of the surface of the object with identifiable points. However, the generation accuracy of the recognizable point is still a main factor that restricts the position identification accuracy, such as a touch lattice generated on a touch pad, which is necessarily affected by the touch material and the touch accuracy to have a certain interval and volume; the machining position of the surface of the part found by machining the dimension tends to be accumulated with an error, resulting in a machining failure. By generating identifiable points with higher precision and smaller surface area on the surface of the object and then scanning the identifiable points, the accurate precision of the surface of the object can be acquired more easily, so that the accuracy of the specific position acquired on the surface of the object is improved. However, the prior art lacks a method for generating high-precision identifiable points or high-precision identifiable points on the surface of an object.

An embodiment of the present invention provides a method for generating recognizable dots by printing, as shown in fig. 1, the method includes the following steps S1-S2.

Step S1: and acquiring printing parameters of the identifiable points.

The printing parameters include one or more parameters required for printing on the printing medium, such as a printing position parameter on the printing medium, a size parameter of an identifiable dot to be printed, the number of times of ejection of liquid for generating the identifiable dot when one identifiable dot is printed, a head parameter for printing, and the like. Before printing on a printing medium, printing parameters required for printing need to be acquired.

Print media include solids such as glass, ceramics, paper sheets, metal parts, and the like. The volume or surface area of the print medium is greater than zero, and the identifiable points can be printed on the surface of the print medium. The identifiable points include dots printed on the surface of the printing medium to enable identification. The identification here includes: the recognition by human eyes, the shooting of an image containing a recognizable point by a camera, the enlargement of the shot image, the recognition of the recognizable point, and the like.

Step S2: and according to the printing parameters, printing a printing area on a printing medium to generate a plurality of identifiable points, wherein identifiable dot matrixes in a set area positioned by the identifiable points in the printing area are different, the positions of the identifiable points in the set area positioned by the identifiable points are the same, and the identifiable dot matrixes in the set area are composed of the identifiable points in the set area.

The setting area for positioning the identifiable point comprises: and determining the position of the set area in the printing area according to the position of the identifiable point in the printing area. The positions of the identifiable points in the set areas positioned by the identifiable points are the same, and the method comprises the following steps: the position of any identifiable point in the set area where the identifiable point is located is the same as the position of any other identifiable point in the set area where the identifiable point is located. After acquiring an identifiable point in the printing area, the position of the setting area for positioning the identifiable point can be determined according to the position of the identifiable point.

In one embodiment, step S2 further includes: and printing a printing area on a printing medium to generate a plurality of identifiable points according to the printing parameters, wherein the identifiable point in the set area with the identifiable point as the center is different from the identifiable point in the set area with any other identifiable point in the printing area as the center, and the identifiable point in the set area is composed of the identifiable points in the set area.

The printing area includes: one or more regions on the print medium. The identifiable lattice includes: and the dot matrix consists of all identifiable points in the set area.

The printing parameters include one or more parameters required to print a plurality of identifiable dots on a side of the print medium to be printed. The printing parameters include distribution information of each identifiable point on the surface to be printed, size parameters of each identifiable point, and the like.

According to the print parameters, a plurality of identifiable points can be printed on the surface to be printed of the print medium, and the identifiable dot matrixes in the setting areas respectively centering on the identifiable points are different. The set area refers to an area in the print area that is positioned by an identifiable point. The recognizable dot matrix in the set area refers to a dot matrix formed by each recognizable dot in the set area. The recognizable dot matrix in the set area includes each recognizable dot in the set area.

By the fact that the recognizable dot matrixes in the set areas respectively positioned by the recognizable dots are different, after one recognizable dot in the printing area is obtained, the position of each recognizable dot on the surface to be printed can be identified by obtaining the position of the recognizable dot matrix in the set area positioned by the recognizable dot.

In one embodiment, the printing parameters include a location parameter of the identifiable point; as shown in fig. 2, step S2 includes step S21: dividing the printing area into a plurality of identical printing sub-areas; step S22: and printing each printing subarea, so that the position of any identifiable point in the printing subarea where the identifiable point is located is different from the position of any other identifiable point in the printing subarea where the identifiable point is located.

By dividing the print area into a plurality of identical print sub-areas, the identifiable points in each print sub-area can be set individually, and the identifiable dot matrices in the set areas positioned by each identifiable point can be printed differently.

By making the position of any identifiable point in the printing sub-area where the identifiable point is located different from the position of any other identifiable point in the printing sub-area where the identifiable point is located, it is possible to make the identifiable dot matrix in the set area where each identifiable point is located different from that of the other identifiable point.

In one embodiment, the defined area comprises a circular area of radius R. Step S2 includes: according to the printing parameters, a plurality of identifiable points are generated in a printing area on the printing medium in a printing mode, identifiable points in circular areas with the radius R, which are respectively positioned by the identifiable points in the printing area, are different, the positions of the identifiable points in the circular areas with the radius R, which are respectively positioned by the identifiable points, are the same, and the identifiable points in the circular areas with the radius R are composed of the identifiable points in the circular areas with the radius R.

R is a number greater than zero. The size of R is related to the size of the identifiable dot on the side to be printed. In one embodiment, R is greater than three times the maximum length of the identifiable point. In the print area, from an identifiable point, a circular area of radius R located by the identifiable point can be obtained.

The identifiable lattice of circular regions comprises: and the identifiable dot matrix is formed by the identifiable points in the circular area. The identifiable lattice for each circular region includes: and aiming at any circular area, the identifiable dot matrix is formed by the identifiable points in the circular area. The recognizable dot matrix of each circular area is different from that of the circular area: for any circular area, the identifiable dot matrix formed by the identifiable points in the circular area is different from the identifiable dot matrix of other circular areas.

When the position of an identifiable point on the area to be printed is identified, the position of the identifiable point in the circular area with the radius of R positioned by the identifiable point is known, the position of the identifiable point in the printing area is obtained by obtaining the identifiable point matrix of the circular area with the radius of R positioned by the identifiable point, the position of the identifiable point matrix can be identified, and then the position of the identifiable point is obtained.

In one embodiment, the set area comprises a square area with a side length a. Step S2 includes: and according to the printing parameters, printing a printing area on the printing medium to generate a plurality of identifiable points, wherein identifiable points in a square area with the radius of A side length respectively positioned by the identifiable points in the printing area are different, the positions of the identifiable points in the square area with the side length of A respectively positioned by the identifiable points are the same, and the identifiable points in the square area with the radius of A side length consist of the identifiable points in the square area with the side length of A. A is a number greater than zero. The size of a is related to the size of the identifiable dot on the side to be printed. In one embodiment, a is greater than three times the maximum length of the identifiable point.

The recognizable lattice of square regions includes: and the identifiable dot matrix is formed by the identifiable points in the square area. The recognizable lattice of each square region includes: and aiming at any square area, the identifiable dot matrix is formed by the identifiable points in the square area. The recognizable dot matrix of each square area is different, namely that: for any square area, the recognizable dot matrix formed by all recognizable points in the square area is different from the recognizable dot matrix of other square areas.

When the position of an identifiable point on the area to be printed is identified, the position of the identifiable point can be identified by acquiring the identifiable dot matrix of the square area with the side length of A positioned by the identifiable point, and then the position of the identifiable point is acquired.

In one embodiment, the printing area is provided with a first identifiable dot matrix and a second identifiable dot matrix. The printing parameters of the identifiable points comprise: a printing parameter of the first identifiable dot matrix and a printing parameter of the second identifiable dot matrix.

As shown in fig. 3, step S2 includes step S23: controlling each nozzle of a first set quantity of nozzles to respectively spray ink to different positions in the set area positioned by the first identifiable point according to the printing parameters of the first identifiable point, and printing in the set area positioned by the first identifiable point to generate a first identifiable point matrix, wherein the first identifiable point matrix is composed of all identifiable points in the set area positioned by the first identifiable point; step S24: and controlling each nozzle in second set amount nozzles to respectively spray ink to different positions in the set area positioned by the second identifiable point according to the printing parameters of the second identifiable point, and printing in the set area positioned by the second identifiable point to generate a second identifiable point which is composed of all identifiable points in the set area positioned by the first identifiable point, wherein the first set amount is different from the second set amount.

The first identifiable point and the second identifiable point are identifiable points on the surface to be printed of the printing medium.

In order to make the second identifiable point matrix different from the first identifiable point matrix, the second identifiable point matrix is made to contain a different number of identifiable points than the first identifiable point matrix. By making the number of nozzles that print the first identifiable dot matrix different from the number of nozzles that print the second identifiable dot matrix, the number of identifiable points that the first identifiable dot matrix contains can be made different from the number of nozzles that the second identifiable dot matrix contains. The second recognizable dot matrix and the first recognizable dot matrix can be distinguished by making the number of the recognizable dots contained in the second recognizable dot matrix different from the number of the recognizable dots contained in the first recognizable dot matrix, and the second recognizable dot matrix and the first recognizable dot matrix can be distinguished.

The fourth identifiable lattice is different from the third identifiable lattice and includes: the distribution of the identifiable points in the fourth identifiable lattice is different from the distribution of the identifiable points in the third identifiable lattice.
