Technical Field

The present invention relates generally to the field of industrial manufacturing. More particularly, the present invention relates to methods, systems, and computer-readable storage media for generating reports of physical characteristics of items.

Background

This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein may include concepts that could be pursued, but are not necessarily ones that have been previously conceived or pursued. Thus, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section.

In the industrial manufacturing field, before manufacturing and manufacturing parts, a demand side designs the parts according to actual demands, then the demand side sends a design scheme to a production side, and the production side manufactures samples according to the design scheme. After the production side produces the sample, the production side submits the sample and a measurement report of the physical characteristics (such as dimension, form and position tolerance, welding standard, surface roughness and annotation) of the sample to the demand side for confirmation. Since the Design solution is usually presented by paper or various types of electronic documents, the types of the electronic documents are, for example, PDF (Portable Document Format), TIF (tag image file Format), BMP (BitMap) Format, JPEG (Joint Photographic Expert Group) Format, or CAD (Computer Aided Design). Whether a drawing or an electronic document, various physical characteristics of the part are discretely marked in the design scheme. If a report of the physical characteristics of the sample is formed, all physical characteristic information dispersedly marked in the design scheme needs to be numbered in sequence and manually added into a list one by one, so that the workload is large and the efficiency is low.

At present, workers generally mark each piece of physical characteristic information of a sample through the function of adding a mark of PDF software and the corresponding functions of picture editing software and CAD software, so that each physical characteristic in a physical characteristic measurement report must have a unique number in a drawing or an electronic document, otherwise, the physical characteristics cannot correspond to each other one by one. However, the content labeled for the physical characteristics of the component still needs to be manually entered into the report. There is still a large amount of work and the efficiency is not effectively improved. Further, the report is formed by completely relying on manual input, and input errors, omission of physical property information, and the like are likely to occur.

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

Methods for generating a physical characteristic report for an article are described below in connection with FIGS. 1-7.

As shown in FIG. 1, the present invention provides a method for generating a physical characteristic report of an article, comprising the steps of: in step S101, an electronic document is displayed. In different implementation scenarios, the type of the electronic document may be PDF, a picture (e.g., an electronic photograph of a paper drawing, or a picture in TIF, BMP, JPEG, or other formats), two-dimensional CAD, or three-dimensional CAD. As shown in FIG. 2, the electronic document contains annotation information 201 for annotating physical characteristics of the item, which may include one or more of the following types: dimensions, form and location tolerances, welding standards, surface roughness, comments, current, voltage, pressure, noise, and the like.

In step S102, receiving a selection of the annotation information 201, so as to automatically number the selected annotation information 201; and the number 202 is displayed on one side of the annotation information. In different implementation scenarios, if the file format of the electronic document is Searchable PDF (Searchable PDF), because the content of the Searchable PDF can be completely read, the annotation information can be directly obtained; if the file format of the electronic document is a non-editable PDF or a picture, the electronic document needs to be assisted by an OCR (Optical Character Recognition) technique, and the annotation information 201 is selected by a cursor. If the file format of the electronic document is CAD, the marking information of the CAD can be directly read. In one embodiment, each of the label messages 201 includes at least one specification value (e.g., a dimension value) or a text (e.g., a text description). In one embodiment, the operation of numbering the selected label information is as follows: and identifying the specification value or the character contained in the selected marking information, and numbering the specification value or the character. As shown in FIG. 3a, if the selected label information only contains a specification value or a text, a number 202 is added to the label information. If the labeling information contains a plurality of specification values, each specification value is added with a number. In different embodiments, the specification values in the same label information may be numbered in the same level, as shown in fig. 3b, and the label information includes 4 specification values, so the numbers 202 of the 4 specification values may be 3, 4, 5, and 6, respectively, or as shown in fig. 3c, the specification values in the same label information may be identified by adding sub-numbers, for example, the numbers 202 of the 4 specification values included in the label information may be 3.1, 3.2, 3.3, and 3.4. When a plurality of specification values are included in the same label information, there are two display manners of the specification value numbers, and the first is, as shown in fig. 3d, to display the number 202 corresponding to each specification value: 4.1, 4.2 and 4.3 are all independently displayed on one side of the annotation information. Secondly, as shown in fig. 3e, the ranges 4.1 to 4.3 of the numbers 202 corresponding to the specification values are displayed on the side of the label information. The user can choose to display the specification value number 202 in the first or second way, and the first or second way can be switched at any time. In addition, as shown in fig. 3f, if the number 4 of the specification values in the same label information is greater than a preset value (e.g., 3), only the number 202 within the preset value may be displayed, for example, only 3.1, 3.2, 3.3, or 3.1 to 3.3.

In one embodiment, the numbers may be provided in a conspicuous color, such as red or blue, to facilitate the staff member to find the corresponding numbers in the electronic document. In another embodiment, the number further comprises a number mark, the number is displayed on the number mark, and the number is displayed on one side of the label information. In one application scenario, the shape of the numbered markers is optional, and the alternatives may be circular, hexagonal, triangular, or diamond, etc., where the selection interface is as shown in fig. 4. As shown in fig. 4, the position of the number display may be selected, and may be displayed on the left, right, upper, or lower side of the label information, for example.

In step S103, a data list is formed from the numbers and the annotation data included in the selected annotation information, and the data list is displayed on one side of the electronic document, and the data list further includes an editing area for editing the data in the data list. In different implementation scenarios, if the file format of the electronic document is Searchable PDF, the annotation information can be directly identified and extracted after being selected; if the file format of the electronic document is a non-editable PDF or a picture, after the annotation information is selected, the annotation data contained in the annotation information needs to be identified and extracted by using an OCR technology. If the file format of the electronic document is CAD, the marking information of the CAD can be directly read. In one embodiment, as shown in fig. 5, after the label data is extracted, the type (e.g. size) of the label data is determined first, and then other information included in the label data, such as subtype (distance), specification, value, unit, upper deviation, lower deviation, maximum value, minimum value, etc., is analyzed and calculated. And finally, filling the information into the data list 505 according to the corresponding categories, and displaying the data list 505 on the right side of the electronic document. In practical applications, there are cases where the aforementioned identified and extracted annotation data is inaccurate. Therefore, in one implementation scenario, an editing area 506 may be provided below the data list 505, so that the annotation data contained in the selected annotation information is edited and revised in the editing area 506. Meanwhile, the data in the data list 505 can be selected to be edited in the editing area 506, and the data can also be edited directly in the data list 505. The data in the edit area 506 and the data in the data list 505 can be synchronized with each other.

In one embodiment, when the labeled data is the geometric tolerance, the interface for editing the geometric tolerance can be directly accessed after the labeled data is selected. As shown in fig. 6, the form and position tolerance editing interface may include 5 category selection editing areas, which may be used to edit the categories of form and position tolerances, the values of form and position tolerances, the reference elements of form and position tolerances, and the like. The category selection edit area may be displayed in the form of a frame, the type of form and position tolerance is displayed in the first frame 601 from left to right, the numerical value of the form and position tolerance is displayed in the second frame 602, and the reference elements of the form and position tolerance, such as A, B, C, are displayed in the third, fourth and fifth frames. The left side of the first frame 601 is an option representing the type of form and position tolerance, the lower side of the second frame 602 is an option of a form and position tolerance numerical modifier, and the lower sides of the third, fourth and fifth frames are options representing the reference modifier and the reference offset of the form and position tolerance. In one embodiment, the selected form and position tolerance type or the reference element type can be filled in the corresponding frame in a click and keyboard input mode, so that the editing time is saved, and the editing operation is simplified.

In step S104, a physical characteristic report of the article is generated from the data list, and the physical characteristic items included in the physical characteristic report are selectable. The data list basically comprises all data of all the labeled information in the electronic document, but only part of the data is needed by the user. Thus, in various embodiments, portions of the data may be selected to form physical characteristic reports according to the user's requirements, and several fixed physical characteristic report templates may be formulated in advance for selection by the user. In addition, the ordering of the physical characteristics in the physical characteristic report may also be adjusted. Therefore, in an application scenario, the user can select items and sort the physical characteristics through the template editor, so as to generate the physical characteristic template meeting the requirements of the user in real time. The items may include positions, measured values, maximum values, minimum values, tolerances, gauges, and the like. In one embodiment, the corresponding data is extracted from the data list according to the physical property items in the physical property report, and the data is filled into the corresponding position of the physical property report, and finally the physical property report shown in fig. 7 is generated.

While the method for generating a physical characteristic report for an article is described above in connection with fig. 1-7, it should be understood by those skilled in the art that the method illustrated in fig. 1-7 is exemplary and not limiting, and that the steps of the method may be modified as desired by those skilled in the art. FIG. 8 is a schematic diagram illustrating extraction of tolerance criteria from annotation information according to an embodiment of the present invention, and a method of extracting tolerances of physical properties from an electronic document is described below in connection with FIG. 8.

In one embodiment, when the selected label information includes a physical property having a tolerance, the data list and the physical property report may further include the tolerance of the physical property. Because the tolerance criteria matched in different designs are different, in different application scenarios, different international criteria can be selected depending on the design, for example: ISO2768m, DIN7168f, GB/T1804m, etc. The tolerance standard can also be freely set by the user if the design is not defined, for example, when the physical property is a certain range of size, the tolerance standard can be set to +0.5 mm for the upper deviation and-0.1 mm for the lower deviation. For the tolerance marked in the marking information, if the file format of the electronic document is Searchable PDF, the tolerance can be directly identified and extracted after the marking information is selected; if the file format of the electronic document is a non-editable PDF or picture, OCR technology is required to identify and extract the tolerance. If the file format of the electronic document is CAD, the marking information of the CAD can be directly read. As shown in fig. 8, the upper deviation is +0.1 mm and the lower deviation is 0 mm, and the tolerance sources are as follows: the figures are labeled. At the same time, the identified tolerance data can be automatically entered under the tolerance item of the data list. If the identified tolerance is not accurate, the tolerance can also be edited and revised in the editing area to make the tolerance of the final entered data list an accurate numerical value.

The method of extracting the tolerance of the physical characteristic from the electronic document is described above with reference to fig. 8. It should be understood by those skilled in the art that the method illustrated in fig. 8 is exemplary and not limiting, and that other methods of extracting tolerances of physical properties may be selected by those skilled in the art as desired. FIG. 9 is a diagram illustrating a map-partitioning of an electronic document according to an embodiment of the present invention. The frame section of the electronic document is described in detail below in conjunction with fig. 9.

In practice, the format of the document is typically larger, for example 841mm long and 594mm wide, as shown in FIG. 9. Therefore, the lengthwise side (long side for short) and the widthwise side (wide side for short) of the document are generally segmented by the line segment indication mark 903. When in segmentation, the segmentation can be carried out according to the length of the long side or the wide side, namely the length of each line is the same; it is also possible to segment unequally, i.e. not all segments are the same length. After segmentation, a segment number is set for each segment, for example, the segment number on the long side is E, F, G, H, etc., and the segment number on the wide side is 1, 2, 3, etc. To facilitate quick numbering, in one embodiment, the electronic document from which the physical property report is to be generated may be partitioned by a plurality of X-axis 901 and Y-axis 902, as shown in FIG. 9. Meanwhile, in order to prevent the X axis 901 and the Y axis 902 from interfering with the display of the electronic document, the X axis 901 and the Y axis 902 may be hidden.

In practical applications, the electronic document is generally subjected to average segmentation, that is, the long side and the broad side are averagely segmented through a plurality of X axes 901 and Y axes 902 according to the lengths of the long side and the broad side. Therefore, the number of the X axis 901 and the number of the Y axis 902 may be set according to the number of the original line segments of the long side and the wide side, respectively, so that the number of the line segments obtained by dividing the long side by the X axis 901 is equal to the number of the original line segments of the long side, and the number of the line segments obtained by dividing the wide side by the Y axis 902 is equal to the number of the original line segments of the wide side, and finally the electronic document may be divided into a plurality of quadrangles having the same area. Each quadrangle corresponds to a map area, and thus the electronic document is divided into a plurality of different map areas. And each map region may be named according to its corresponding segment designation, e.g., E3, F1, G2. Different map areas may correspond to different area numbers.

After the electronic document is subjected to the map frame partition, the number of each piece of labeling information falls into one map frame area. Meanwhile, the corresponding relation between each number and the map sheet area can be established according to the coordinate information of each number and the coordinate information covered by each map sheet area. The corresponding relation can be displayed in the data list, so that when the area of the electronic document is too large, the map area can be positioned through the area number corresponding to a certain number, the range of searching for the certain number is greatly reduced, and a user can quickly and accurately find the specific position of the certain number in the electronic document. In addition, in actual operation, in the process of partitioning the electronic document into the map width, since the original segments of the long side and the wide side are not evenly divided in the document of the design, the start ends of the line segments divided by the X axis 901 and the Y axis 902 cannot accurately correspond to the original line segment indication marks 903, so that an error occurs in the corresponding relationship between the numbers and the map width region. For example, as shown in FIG. 9, the number 202 is actually located within the map view area H2. However, since the first X axis 901-1 is located below its correct position (indicated by a dotted line in the figure), the user may mistakenly assume that the number 202 is located in the drawing frame region G2, and therefore, the first X axis 901-1 needs to be moved (for example, directly dragged) to the correct position (indicated by a dotted line in the figure), and the start ends of the line segments divided by the X axis 901 and the Y axis 902 are both made to correspond to the original line segment indicator 903, so that the line segments divided by the X axis 901 and the Y axis 902 are made to correspond to the original line segments precisely.
