Abstract
Description
Technical Field
[0001] This invention relates to the field of engineering drawing analysis technology, specifically to a method and system for compiling process diagrams based on a cut-out viewport display. Background Technology
[0002] A machining process card is a process document used to record and guide the details of each step in the machining process of a part, including the equipment, tools, machining parameters, and inspection requirements. It is typically used in mass production to ensure standardization and consistency in the machining process.
[0003] In traditional manufacturing and process review, process engineers must manually compare the part assembly drawing or process drawing and use a "copy-delete" method to create simplified process diagrams for each machining process card. They must extract the necessary elements from existing part drawings and edit them. Furthermore, the creation of machining process cards always requires selecting specific areas from the part drawings as the basis for the simplified process diagrams. This operational mode is not only cumbersome and prone to errors, but also makes it difficult for process engineers to accurately and quickly locate the required specific areas from a vast amount of part drawing information when the part structure is complex, directly leading to low work efficiency.
[0004] Therefore, there is an urgent need to provide a more efficient method that can extract the required information from a large number of part drawings to create process diagrams. Summary of the Invention
[0005] This invention provides a method and system for creating process diagrams based on a cut-out viewport display, in order to solve at least one of the technical problems existing in the prior art.
[0006] In a first aspect, the present invention provides a method for compiling process diagrams based on a cut-out viewport display, comprising:
[0007] Create part pages and process pages, and establish a link to the part page by selecting the process diagram area in the process page corresponding to the target process;
[0008] In the process diagram area, the original image source of the part drawing in the part page is loaded through the link of the part page, and a specified area is selected and cropped in the original image source;
[0009] The target area in the process diagram area displays the specified area that has been cropped, and the coordinate systems of the target area and the specified area are aligned.
[0010] Furthermore, the process of creating part pages and process pages specifically includes:
[0011] Create a part page that is configured to load part drawings of the part to be processed;
[0012] Based on the part drawing, the processing technology of the part to be processed is determined, resulting in multiple processing steps arranged in the processing sequence;
[0013] Create multiple process pages, with each process page corresponding to a processing step.
[0014] Furthermore, the original image source of the part drawing is stored in a non-volatile storage medium and loaded into memory through an image decoder to form an original image buffer, and the data in the original image buffer is in a read-only state.
[0015] A global coordinate system is established in the original image source of the part drawing, and the regional information of the specified area is determined through the global coordinate system.
[0016] Furthermore, during the process of loading the original image source of the part drawing in the part page, the address offset of the pixel data block in the global coordinate system in the original image buffer is calculated, and the global coordinate system is restored based on the address offset.
[0017] Furthermore, a canvas coordinate system is established in the target area of the process diagram area, and the area information of the target area is determined through the canvas coordinate system;
[0018] By aligning the canvas coordinate system with the global coordinate system, the image in the specified cropped area is completely placed into the target area.
[0019] Furthermore, when the size of the target region is different from the size of the specified region, the size of the target region is scaled.
[0020] Furthermore, during the scaling of the target area, the physical size and display resolution of the original image source of the part drawing are bound together.
[0021] Secondly, the present invention provides a process diagram compilation system based on a cut-out viewport display, comprising:
[0022] The page creation unit is used to create part pages and process pages, and to establish a link to the part page by selecting the process diagram area in the process page corresponding to the target process.
[0023] The drawing cropping unit is used to load the original image source of the part drawing in the part page through the link of the part page in the process diagram area, and select and crop a specified area in the original image source;
[0024] A simplified diagram display unit is used to display the specified area that has been cropped in the target area of the process simplified diagram area, and to align the coordinate system of the target area with that of the specified area.
[0025] Thirdly, embodiments of the present invention provide an electronic device, the electronic device comprising:
[0026] At least one processor; and a memory communicatively connected to the at least one processor;
[0027] The memory stores a computer program that can be executed by at least one processor, such that the at least one processor is able to perform the steps of the method according to any embodiment of the present invention.
[0028] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing computer instructions that are used to cause a processor to execute the steps of any embodiment of the method of the present invention.
[0029] Compared with the prior art, the present invention has the following advantages:
[0030] The technical solution in this embodiment of the invention first creates a part page and a process page. Then, in the process page corresponding to the target process, a link to the part page is established by selecting a process diagram area. Next, in the process diagram area, the original image source of the part drawing in the part page is loaded through the link. A specified area is selected and cropped from the original image source. Finally, the cropped specified area is displayed in the target area of the process diagram area, and the coordinate systems of the target area and the specified area are aligned. Through this technical solution, the required content can be extracted from a large number of part drawings more efficiently for compiling process diagrams in the processing operation card.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] Before introducing the technical solution of this invention, it should be noted that in the existing machining process planning, the parts to be processed are manufactured through multiple processes. Each processing process requires a process diagram to guide the operators in completing each process. Furthermore, the traditional method for creating the process diagram for each process is to manually refer to the overall part drawing and draw a simplified process diagram for each process using a "copy-delete" method. This method has the following drawbacks:
[0040] 1) Low drawing efficiency: Each process requires repeatedly deleting a large number of irrelevant lines, which multiplies the workload, especially when the original part drawing has a large amount of information and the processing process is complicated;
[0041] 2) Poor drawing consistency: When manually deleting irrelevant lines, it is easy to miss or delete them incorrectly, resulting in the process diagram in the process page not matching the target drawing;
[0042] 3) Redundancy in drawing information: Features of non-processes are easily mixed in the process diagram of the target process, which may lead to operator errors.
[0043] 4) Difficult to digitize: Manual process drawings cannot be directly integrated with Manufacturing Execution System (MES) and CNC system, hindering the implementation of intelligent automated manufacturing.
[0044] This invention provides a method for creating process diagrams based on a cut-out viewport display. Figure 1This is a flowchart illustrating a process diagram compilation method based on a cut-out viewport display, provided by an embodiment of the present invention. This embodiment is particularly applicable to the situation where a partial view corresponding to a certain process is extracted from a large number of part drawings to compile a process diagram. This method can be executed by a process diagram compilation system based on a cut-out viewport display. The system can be implemented in software and / or hardware and can be configured in an electronic device.
[0045] like Figure 1 As shown, the method specifically includes:
[0046] S1, create part pages and process pages. In the process page corresponding to the target process, select the process diagram area to create a link to the part page.
[0047] In this context, the target process refers to a specific machining operation of the part to be processed, or a specific step within a machining operation. The part page provides an overall view or final target of the target process, while the process page guides the processing of each specific operation or step, such as guiding the positioning, clamping, tooling, and dimensions of each operation. Typically, process pages are arranged according to the machining sequence. From a hierarchical perspective, the part page is at the top level, while the process page is at the bottom level. The process page must be designed in accordance with the final requirements of the part page, such as dimensions, tolerances, and datum points, and the machining result based on the process page should be consistent with the final target of the part page.
[0048] In addition, the location of the process diagram area is the area preset on the process page for placing process diagrams.
[0049] Optionally, the process of creating part pages and operation pages specifically includes:
[0050] S101, A part page is created through the process diagram compilation system. The part page is configured to load part drawings of the parts to be processed.
[0051] S102, Based on the part drawing, determine the processing technology of the part to be processed, and obtain multiple processing steps arranged in the processing sequence;
[0052] S103, multiple process pages are created through the process diagram compilation system, and each process page corresponds to a processing process.
[0053] In the process diagram creation system, staff can create multiple pages based on the machining process of the parts to be processed. These pages include part pages and process pages (general diagrams). In traditional process review, a machining process card is often created, recording relevant information for each process step. Following this, corresponding machining process cards are typically created, recording process diagrams and relevant information for each step. Staff can create corresponding pages in the process diagram creation system according to their individual needs or habits.
[0054] Optionally, the original image source of the part drawing is stored in a non-volatile storage medium and loaded into memory via an image decoder to form an original image buffer, where the data is read-only. It is understood that the part drawing, stored in the storage medium, is read-only and cannot be modified when the part page is opened. Specifically, during the storage phase, the original image source is saved in a compressed format in a non-volatile storage medium, such as a hard drive, SSD, or flash memory. In this state, the image cannot be directly used by the GPU or display system. During the reading phase, the system reads the compressed image data from the storage medium through an interface and transmits it to the original image buffer. During the decoding phase, the image decoder (hardware decoder or software decoding library) decodes the compressed data, converting it into uncompressed raw pixel data. In the original image buffer phase, the decoded raw image data is loaded into a contiguous buffer in memory, forming a directly accessible pixel array.
[0055] It should be noted that the process diagram creation system supports various part drawing formats. The original image source for part drawings can be vector graphics or raster graphics; for example, common CAD drawings use vector graphics formats such as DWG and DXF. Part drawing formats include PDF, DWG, DXF, PNG, and TIFF, among others.
[0056] Figure 2 This is a schematic diagram of an overall view of a part drawing provided in an embodiment of the present invention, such as... Figure 2 As shown, various views of the part to be processed are distributed in different areas of the part drawing, and each view contains different annotation information. The image source of the part drawing also has a global coordinate system (denoted as O1). In a typical setup, the origin (0,0) of the global coordinate system O1 is located at the upper left corner of the image, the x-axis is to the right, the y-axis is downward, and the coordinate system unit is pixels or drawing units (such as millimeters, inches, etc.).
[0057] Part drawings typically include partial views such as the front view, top view, side view, and sectional view of the part to be machined. These partial views usually serve as a simplified process diagram for a specific machining operation.
[0058] S2, in the process diagram area, load the original image source of the part drawing in the part page through the link of the part page, and select and crop the specified area in the original image source.
[0059] Specifically, a process diagram area is preset on the process page. After clicking on the process diagram area, click "Insert" in the upper left corner of the process diagram compilation system and select "Insert Part Page." At this time, the original image source of the part drawing will be loaded on the process page. This original image source is in read-only mode and cannot be modified. It is understandable that whether the original image source of the part drawing is loaded on the part page or the process page, it points to the same underlying file, and the underlying file cannot be modified.
[0060] Figure 3 This is a schematic diagram of a designated area of a part drawing provided in an embodiment of the present invention, such as... Figure 3 As shown, the rectangular selection tool is used to select a specific area in the part drawing. This selected area is typically a single view of the part drawing, such as the front view of the part to be processed. The graphic information of the selected area includes the shape, dimensions, and coordinates of the part within that area. The shape of the selected area is determined by the outer contour of the part to be processed; generally, a rectangular or circular selection box can be used, or other irregular shapes can be selected.
[0061] Optionally, a global coordinate system O1 is established in the original image source of the part drawing, which can determine the area information of a specified area.
[0062] When the selection tool uses a rectangle, the region information includes the starting coordinates, width, and height of the specified area. For example, the starting coordinates of the specified area are: Let w be the width of the specified area and h be the height of the specified area; where, , w and h are in pixels, or can be obtained by converting drawing units to resolution.
[0063] The designated region (ROI) corresponds to a specific sub-region of the original image source of the part drawing, representing a specific process step. Examples include welding process diagrams, partial sectional views, or machining sequence diagrams. The designated ROI can be manually specified (by the user selecting an area using the mouse).
[0064] Furthermore, when loading the original image source of the part drawing in the part page, since the underlying file is not loaded directly, but rather the original image source data is transferred to a temporary memory buffer for decoding after reading the underlying file, the original image source of the loaded part drawing has an address offset. Therefore, it is necessary to calculate the offset during the loading process to calibrate the coordinate system.
[0065] Optionally, during the process of loading the original image source of the part drawing in the part page, the address offset of the pixel data block in the global coordinate system O1 is calculated, and the global coordinate system O1 is restored based on the address offset.
[0066] Furthermore, the cropping operation can be achieved through graphics APIs such as "glScissor" in OpenGL, or "BitBlt" in conjunction with "SRCAND" in GDI, without modifying the source image data.
[0067] S3 displays the specified area to be cut in the target area of the process diagram area, and aligns the coordinate systems of the target area and the specified area.
[0068] Optionally, a canvas coordinate system O2 is established in the target area of the process diagram area, which can determine the area information of the target area; the canvas coordinate system O2 can also be aligned with the global coordinate system O1 so that the image in the specified area being cropped can be completely placed in the target area; and when the size of the target area is different from the size of the specified area, the size of the target area is scaled.
[0069] Figure 4 This is a schematic diagram of a process diagram area on a process page provided in an embodiment of the present invention, such as... Figure 4 As shown, the process diagram area includes a target area displaying the main view of the part to be processed and a shaded area (blank area) where no image information is displayed. The target area is set as a rectangle, and its information includes the starting coordinates, width, and height. For example, the starting coordinates of the target area are... Let W be the width of the target region and H be the height of the target region; where, , W and H are in pixels, or obtained by converting from drawing units and resolution. The target area and the image source both point to the same underlying file, but they are displayed in separate view windows.
[0070] Furthermore, the target region size (W, H) can differ from the specified region size (w, h), supporting proportional or free scaling. Finally, the scaled image data is drawn onto the target region of the canvas, aligned to its top left corner. .
[0071] Drawing operations can be completed through a single graphics API call, for example:
[0072] In a web environment, graphics are drawn using the command: CanvasRenderingContext2D.drawImage(image, x1,y1, w, h, x2, y2, W, H).
[0073] It should be noted that no temporary image files or memory bitmaps are generated during the entire process of creating the process diagram. The data flow is: source image → GPU texture → frame buffer.
[0074] Compared to the traditional "copy-delete" approach, this solution eliminates the need for step-by-step deletion. Instead, it uses a single selection to draw the process diagram, taking approximately 3 seconds, while existing solutions require 10-30 minutes to generate the process diagram. Furthermore, traditional solutions are prone to errors or omissions during manual line deletion, leading to information redundancy. This solution, however, can restore the original part drawing 1:1 with zero loss.
[0075] Furthermore, this solution is suitable for scenarios where multiple users concurrently access the same drawing, meaning that multiple users can access the same drawing in the system. Since the original part drawing data exists in the underlying file and cannot be modified, it supports concurrent access by multiple users without causing interference between them.
[0076] Combination Figure 4 The process page includes a process diagram area and a text area for recording processing information. Clicking anywhere in the process diagram area will reopen the original image source of the part drawing, and different image information can be displayed in the target area by adjusting a specified area.
[0077] Furthermore, during the scaling of the target area, the physical size and display resolution of the original image source of the part drawing are bound together.
[0078] It should be noted that existing technologies include methods that extract a local image from the part drawing on the part page using an image cropping and scaling tool, generate an intermediate image, copy the generated intermediate image to the process diagram area of the machining process card, and finally adjust the intermediate image in the process diagram area. However, this method requires caching the intermediate image, and the scaling process does not bind the physical size and display resolution, resulting in image distortion. Furthermore, the process of copying the part drawing from the part page to the machining process card results in an inconsistency between the coordinate systems of the source image and the target area, leading to an unclear mapping relationship. Additionally, it lacks semantic alignment capabilities with the engineering drawing coordinate system (e.g., it does not incorporate structured information such as the drawing frame, title block, and process annotations).
[0079] One of the core aspects of this invention is to provide a process diagram extraction and display strategy that features single-draw call, no intermediate buffer, precise coordinate mapping, and controllable scale.
[0080] Optionally, when updating the part drawing on the part page, the following steps are repeated: In the process diagram area, the original image source of the updated part drawing on the part page is loaded via a link in the part page; a specified area is selected and cropped in the original image source; the cropped specified area is displayed in the target area of the process diagram area, and the coordinate systems of the target area and the specified area are aligned; thus completing the modification of the process diagram.
[0081] It should be noted that when partial changes are needed to the part drawing, the process cards are also affected by the changes and need to be modified accordingly. In this case, the traditional "copy-delete" method cannot pinpoint which process cards need modification, and even if these process cards are located, they cannot be directly modified; the process cards must be regenerated by copying and deleting again. However, the solution in this embodiment records the coordinate position information of each process diagram in the part drawing during the creation of each process card's process diagram. Therefore, it can more efficiently identify the process cards that need modification, and modifying the process cards only requires re-extracting them from the part drawing.
[0082] One of the core features of this invention is its adaptability to situations where part drawings need to be modified. When part drawings are changed due to design changes or other alterations to the part to be processed, the process diagrams in the process cards for each process need to be adapted accordingly. Thus, when process cards are changed, only simple adjustments are required, greatly reducing the workload of process card modifications caused by changes in part drawings and improving the efficiency of process card modifications.
[0083] The technical solution in this embodiment of the invention creates part pages and process pages, links to relevant drawings on the part pages, and allows cropping of the drawings on the process pages. Neither the part page nor the process page can modify the original drawings. Simultaneously, the coordinate systems of a specified area on the part page and a target area on the process page are aligned, and the physical dimensions and display resolution of the original drawings are bound, ensuring that the image of the specified area is completely placed within the target area. Furthermore, when partial modifications to the original drawings are needed, the process diagram can be quickly modified.
[0084] Under the same inventive concept, a process diagram compilation system based on a cut-out viewport display is also involved. Figure 5 This is a schematic diagram of a process diagram compilation system based on a cutting viewport display, provided as an embodiment of the present invention. Figure 5 As shown, the system specifically includes:
[0085] Page creation unit 100 is used to create part pages and process pages. It selects the process diagram area in the process page corresponding to the target process to establish a link to the part page.
[0086] The drawing cropping unit 200 is used to load the original image source of the part drawing in the part page through the link of the part page in the process diagram area, and select and crop the specified area in the original image source.
[0087] The simplified diagram display unit 300 is used to display the specified area to be cut in the target area of the process simplified diagram area, and to align the coordinate system of the target area with that of the specified area.
[0088] The technical solution in this embodiment of the invention, through the collaboration of various units in the system, can more efficiently and accurately crop the local views corresponding to each process in the part drawing to the target area of the process diagram area for display. Furthermore, when it is necessary to modify the part drawing, it is only necessary to determine the process page involved in the area to be modified, then re-insert the modified part drawing, and re-select and crop to quickly complete the modification of the process card. Alternatively, when it is necessary to modify the machining process, it is only necessary to re-select and crop the part drawing to quickly complete the modification of the process card.
[0089] Under the same inventive concept, an electronic device is also involved. Figure 6 This is a schematic diagram of an electronic device implementing the process diagram compilation method based on a cut-out viewport display according to embodiments of the present invention.
