[0002] In the field of modern industrial design and manufacturing, size report is an important part of product design, production and quality control process. The traditional size report generation method mainly relies on professional software such as CM4D and other measurement matching data system software. Although these software are powerful, they are expensive, complex to operate and difficult to meet individual needs.

[0003] With the development of Internet technology, online size report system based on B / S architecture has gradually become a new trend, realizing online rendering of measurement points and dynamic export of reports. When rendering measurement points online, each measurement point corresponds to a measurement point detail page. When rendering three-dimensional (3D) measurement points online, a line is drawn between the 3D measurement point and its corresponding measurement point detail page. The intersection of multiple lines affects viewing and analysis. Moreover, the export method of size report usually saves specific page screenshots as pictures, which makes it difficult to quickly search and find specific measurement point information in size reports of hundreds of pages, and thus it is difficult to ensure the efficiency and flexibility of users using size reports.

The rendering module is also used to draw the connection between the 3D annotated measurement points corresponding to the target's 2D coordinates and the measurement point details page corresponding to the target's center point coordinates that match the target's 2D coordinates, and to render the 3D measurement point dimension report.

[0012] Fourthly, a size report generation apparatus is provided, the apparatus comprising: The second acquisition module is used to acquire a screenshot corresponding to each loading page of the 3D measurement points. The screenshot is an image obtained by cropping the 3D model and 3D annotation measurement points from the dimension report rendered based on the dimension report rendering method described in the first aspect above. The loading page includes a preset number of 3D measurement points.

[0015] According to the technical content provided in this application, the measurement point information of user-preset 3D measurement points is obtained. This measurement point information includes the 3D coordinates of the 3D measurement points. Based on the 3D coordinates, each 3D measurement point is rendered in the 3D model to obtain 3D labeled measurement points. A measurement point detail page corresponding to each 3D labeled measurement point is rendered based on the measurement point information. The 3D coordinates of the 3D measurement points are converted into screen 2D coordinates. Based on the screen 2D coordinates and the center point coordinates of the measurement point detail page, the target 2D coordinates in the screen 2D coordinates and the target center point coordinates matching the target 2D coordinates are determined. A connection is drawn between the 3D labeled measurement point corresponding to the target 2D coordinates and the measurement point detail page corresponding to the target center point coordinates matching the target 2D coordinates. A 3D measurement point dimension report is rendered. The connection between the matched target 2D coordinates and the target center point coordinates ensures that the connection between the 3D labeled measurement points and the measurement point detail page does not intersect, facilitating the viewing and analysis of the 3D measurement points.

Detailed Implementation

[0018] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the scope of the present application.

[0019] For ease of understanding, the system to which this application applies will first be described. The dimension report rendering method and dimension report generation method provided in this application can be applied to, for example... Figure 1 In the system architecture shown.

[0020] Example 1 Terminal 110 communicates with server 120 via a network. Users can pre-set the measurement point information of vehicle 3D measurement points through terminal 110. The dimension report rendering method and dimension report generation method can be executed on terminal 110 or server 120. Taking the dimension report rendering on server 120 as an example, server 120 obtains the measurement point information of the 3D measurement points pre-set by the user. This measurement point information includes the 3D coordinates of the 3D measurement points. Based on the 3D coordinates, each 3D measurement point is rendered in the 3D model to obtain 3D labeled measurement points. The server also renders the measurement point details page corresponding to each 3D labeled measurement point based on the measurement point information. The 3D coordinates of the 3D measurement points are converted into screen 2D coordinates. Based on the screen 2D coordinates and the center point coordinates of the measurement point details page, the target 2D coordinates in the screen 2D coordinates and the target center point coordinates matching the target 2D coordinates are determined. A connection is drawn between the 3D labeled measurement point corresponding to the target 2D coordinates and the measurement point details page corresponding to the target center point coordinates matching the target 2D coordinates. Finally, the dimension report of the 3D measurement points is rendered. Among them, terminal 110 can be, but is not limited to, various personal computers, laptops, smartphones and tablets, and server 120 can be implemented by independent servers or server clusters composed of multiple servers.

[0021] The system architecture of the dimension report rendering method and dimension report generation method provided in this application can be divided into a project management module, a model upload module, a measurement point input module, a parameter configuration module, a report rendering module, and a report export module. Its front end is implemented using Vue + three.js, and its back end is implemented using Java + ittext.

[0022] The project management module provides configuration management for projects, allowing users to configure information such as project manager, contact person, monitoring thresholds (email or phone alerts when thresholds are exceeded), and associated models.

[0023] The model upload module allows users to upload 3D models online. Since model files are generally large, it provides large file chunking upload and resume functionality. For example, if an OBJ model file is 300MB in size and each chunk is set to 10MB, the OBJ model file will be split into 30 smaller chunks for upload. If the upload is interrupted at 50%, it will resume from 50% on the next upload, without re-uploading the previously uploaded portions.

[0024] The measurement point entry module allows users to batch set measurement point information by uploading an Excel spreadsheet or a DMO file, or to add, delete, modify, and query information for a single measurement point online.

[0025] The template configuration module allows you to configure the format for displaying detailed two-dimensional information about the measurement points. For example, you can configure it to be tabular or chart-based, and you can select the specific fields to be displayed.

[0026] The report rendering module uses the three.js 3D rendering engine in the browser to render dimension reports online, including 3D models, 3D measurement points on the model, and detailed information on the 2D measurement points. During the rendering process, intelligent layout and anti-interference measures ensure perfect display of measurement points. Custom measurement points can be manipulated and dragged to adjust their position and can be displayed on the next page, thus realizing the dimension report rendering method.

[0027] The report export module combines 3D model screenshots and 2D measurement point details page information to use iText to draw specific measurement point details and generate an editable document, thus realizing a method for generating dimension reports. The editable document includes, but is not limited to, searchable PDF reports and Word documents.

[0028] Figure 2 A flowchart illustrating a size report rendering method provided in this application embodiment, the method can be performed by, for example... Figure 1 The terminal 110 or server 120 in the system shown executes this. In the first embodiment, as... Figure 2 As shown, the method may include the following steps: S210: Obtain the measurement point information of the three-dimensional measurement points preset by the user.

[0029] 3D measurement points are a series of points with specific geometric meanings selected on the surface or internal structure of an object, such as intersections of object contour lines, extreme points of surface curvature, and connection points of structural components. They are used to accurately describe the shape, size, positional relationships, and deformation of the object. The objects can include vehicles, household items, furniture, and other items with 3D structures.

[0030] Measurement point information is a collection of key data recorded in 3D measurement, which may include the 3D coordinates, number, name, classification, acquisition time node, symmetry relationship, etc. of the 3D measurement point.

[0031] Users pre-set the measurement point information of 3D measurement points for which dimension reports need to be generated in batches through the measurement point input module and save it to terminal 110. When the dimension report generation command is executed, the measurement point information of the 3D measurement points pre-set by the user is retrieved.

[0032] S220: Based on the three-dimensional coordinates of the three-dimensional measurement points, render each three-dimensional measurement point in the three-dimensional model to obtain three-dimensional labeled measurement points, and render the measurement point details page corresponding to each three-dimensional labeled measurement point based on the measurement point information.

[0033] Load the 3D model corresponding to the 3D measurement point in the browser using three.js, set up an area in the middle of the page to display the 3D model, and set up a measurement point details page to display N 3D measurement points through the template configuration module, and display the 3D measurement points in paginated form with N measurement points per page.

[0034] Based on the 3D coordinates of the 3D measurement points, each measurement point is rendered using a mesh in the 3D model to annotate the 3D measurement points on the 3D model. These annotated points are called 3D labeled measurement points. To intelligently obtain a perfect layout of observation points, a cube containing all 3D coordinates is created to determine the scaling ratio of the 3D model, ensuring that the 3D measurement points on a single page of the 3D model always occupy a certain proportion of the rendering area.

[0035] Specifically, a cube containing 3D coordinates of 3D measurement points is created, and the center of the cube is used as the center of the 3D model. The first width and first height of the cube, as well as the second width and second height of the rendering area of ​​the 3D model, are obtained respectively. Based on the first width, first height, second width, second height and preset model area ratio, the scaling ratio of the 3D model is determined.

[0036] The preset model area ratio is the proportion of the rendering area occupied by 3D measurement points in a pre-set 3D model page. The preset model area ratio can be set according to the user's actual needs, such as 80%, which can ensure that the 3D measurement points in a 3D model page occupy 80% of the rendering area.

[0037] The scaling ratio is the ratio by which the height and width of the 3D model are magnified or reduced. The height scaling ratio of the 3D model is the ratio of the product of the second height and the preset model area ratio to the first height. The width scaling ratio of the 3D model is the ratio of the product of the second width and the preset model area ratio to the first width.

[0038] Based on the measured point information, the 3D measured point details page is rendered according to the configured template, displayed sequentially from top to bottom and left to right on both sides of the rendering canvas, while simultaneously recording the 2D coordinates of the measured point details page. If the template is a table, it is rendered using `table`; if it is a chart, it is rendered using `echarts`. The measured point details page displays the specific content of the 3D measured point, which may include information such as the measured point number, monitoring parameters, equipment model, and acquisition time.

[0039] S230 converts the three-dimensional coordinates of the three-dimensional measurement point into two-dimensional coordinates on the screen, and determines the target two-dimensional coordinates in the screen two-dimensional coordinates and the target center point coordinates that match the target two-dimensional coordinates based on the screen two-dimensional coordinates and the center point coordinates of the measurement point details page.

[0040] After the 3D measurement points are rendered onto the 3D model in the browser, their positions on the rendering canvas are 2D coordinates, i.e., screen 2D coordinates. Projecting these 3D coordinates onto the camera plane transforms them into 2D coordinates, resulting in a standard vector. The returned result is the standard device coordinates corresponding to the world coordinate system under the camera object matrix transformation. These standard device coordinates are then converted to screen coordinates, i.e., screen 2D coordinates. The center point of the measurement point details page is the intersection of the center lines of the page's wide and long sides. Its coordinates can be obtained from the coordinates of the page's wide and long sides.

[0041] Based on the screen's 2D coordinates and the center point coordinates of the measurement point details page, first determine the target 2D coordinate with the smallest ordinate value in the screen's 2D coordinates. The target 2D coordinate is the coordinate with the smallest ordinate value in the screen's 2D coordinates. Based on the angle between the target 2D coordinate and the center point coordinates of all measurement point details pages, connect the center point coordinate with the smallest angle to the target 2D coordinate and check if the connection is successful. If not, connect the center point coordinate corresponding to the next smaller angle to the target 2D coordinate and check if the connection is successful again, until a target center point coordinate matching the target 2D coordinate is found. The connection between the target center point coordinate and the target 2D coordinate satisfies the condition that there are pairs of screen 2D coordinates and center point coordinates on the left and right sides of the connection. A successful connection means that the number of screen 2D coordinates and center point coordinates on the same side of the connection is the same, and the number of screen 2D coordinates and center point coordinates on the left side of the connection is the same. Continue to pair the screen 2D coordinates and center point coordinates on the left and right sides of the connection to ensure that the connections do not intersect. A connection failure means that the number of screen 2D coordinates and center point coordinates on the same side of the connection is not the same. It is necessary to find a new target center point coordinate that matches the target 2D coordinates. The target center point coordinates are confirmed by connecting them to the target 2D coordinates in order of increasing tilt angle, until the number of screen 2D coordinates and center point coordinates on the same side of the connection is the same.

[0042] S240: Draw the connection between the 3D annotated measurement points corresponding to the target's 2D coordinates and the measurement point details page corresponding to the target's center point coordinates that match the target's 2D coordinates, and render the 3D measurement point dimension report.

[0043] After drawing the first pairing line between the 3D annotation measurement point corresponding to the screen 2D coordinates that is determined as the target 2D coordinates and the measurement point details page corresponding to the target center point coordinates that match the target 2D coordinates, based on the remaining screen 2D coordinates on the left and right sides of the pairing line, return to step S230 and continue to find the pairing line between the 3D annotation measurement point corresponding to the screen 2D coordinates that is determined as the target 2D coordinates and the measurement point details page corresponding to the target center point coordinates that match the target 2D coordinates. The screen 2D coordinates and center point coordinates are both divided into different regions until the last pairing line between the 3D annotation measurement point corresponding to the screen 2D coordinates that is determined as the target 2D coordinates and the measurement point details page corresponding to the target center point coordinates that match the target 2D coordinates is drawn. By refining and dividing the screen 2D coordinates and center point coordinates into different regions, the exponential iteration speed can make the pairing line between the 3D annotation measurement point corresponding to the screen 2D coordinates that is determined as the target 2D coordinates and the measurement point details page corresponding to the target center point coordinates that match the target 2D coordinates.

[0044] Specifically, after matching the target center point coordinates corresponding to the target 2D coordinates, a pairing connection is drawn between the 3D annotation measurement point corresponding to the target 2D coordinates and the measurement point details page corresponding to the target center point coordinates. It should be noted that only connections where the number of screen 2D coordinates and center point coordinates in the right area of ​​the connection is the same, or the number of screen 2D coordinates and center point coordinates in the left area is also the same, are considered paired connections. From the remaining screen 2D coordinates, a step is taken to select the target 2D coordinate with the smallest y-coordinate value. From the remaining screen 2D coordinates, the screen 2D coordinate with the smallest y-value is determined as the current target 2D coordinate. The corresponding target center point coordinate is then searched for, and a connection is drawn between the 3D annotation measurement point corresponding to the current target 2D coordinate and the measurement point details page corresponding to its target center point coordinates. The above steps are executed in a loop until the connection between the last screen 2D coordinate corresponding to the 3D annotation measurement point and the last center point coordinate corresponding to the measurement point details page is drawn.

[0045] As can be seen, this embodiment of the application obtains the measurement point information of the three-dimensional measurement points preset by the user. The measurement point information includes the three-dimensional coordinates of the three-dimensional measurement points. Based on the three-dimensional coordinates of the three-dimensional measurement points, each three-dimensional measurement point is rendered in the three-dimensional model to obtain three-dimensional labeled measurement points. The measurement point details page corresponding to each three-dimensional labeled measurement point is rendered based on the measurement point information. The three-dimensional coordinates of the three-dimensional measurement points are converted into two-dimensional coordinates on the screen. Based on the two-dimensional coordinates on the screen and the center point coordinates of the measurement point details page, the target two-dimensional coordinates in the screen two-dimensional coordinates and the target center point coordinates that match the target two-dimensional coordinates are determined. A connection line is drawn between the three-dimensional labeled measurement point corresponding to the target two-dimensional coordinates and the measurement point details page corresponding to the target center point coordinates that match the target two-dimensional coordinates. The dimension report of the three-dimensional measurement points is rendered. The connection line between the matched target two-dimensional coordinates and the target center point coordinates can ensure that the connection line between the three-dimensional labeled measurement points and the measurement point details page does not intersect, which facilitates the viewing and analysis of the three-dimensional measurement points.

[0046] Furthermore, based on the screen's two-dimensional coordinates and the center point coordinates of the measurement point details page, the target two-dimensional coordinates in the screen's two-dimensional coordinates and the target center point coordinates that match the target two-dimensional coordinates are determined, including: Based on the connection between the three-dimensional annotation measurement points corresponding to the target two-dimensional coordinates and the measurement point details page, determine the inclination angle between the target two-dimensional coordinates and the coordinates of each center point; Based on the order of the dip angles from smallest to largest, the coordinates of the center point corresponding to the first dip angle are determined as the coordinates of the first center point. Draw the first line connecting the 3D labeled measurement points corresponding to the target's 2D coordinates and the measurement point details page corresponding to the first center point's coordinates; Loop through the remaining screen 2D coordinates, including the number of 2D coordinates to the left or right of the first line, and the remaining center point coordinates, including the number of center point coordinates to the left or right of the first line. Based on the number of two-dimensional coordinates and the number of center point coordinates on the same side of the first connecting line, determine the target center point coordinates that match the target two-dimensional coordinates.

[0047] Determine the target 2D coordinate with the smallest y-coordinate value in the 2D coordinate system on the screen. That is, find the coordinate with the smallest y-value in the 2D coordinate system on the screen and determine it as the target 2D coordinate. Connect the 3D labeled measurement point corresponding to the target 2D coordinate with all measurement point details pages.

[0048] After obtaining the lines connecting the 3D labeled measurement points corresponding to the target 2D coordinates and the center point of the measurement point details page, calculate the inclination angle of each line based on the target 2D coordinates and the center point coordinates of the measurement point details page. Arrange the inclination angles in ascending order, with the first inclination angle being the smallest, the second the next smallest, and the last the largest. Determine the center point coordinates with the smallest inclination angle as the first center point coordinates, and draw the first line connecting the 3D labeled measurement points corresponding to the target 2D coordinates and the measurement point details page corresponding to the first center point coordinates. The first line will divide the remaining screen 2D coordinates and center point coordinates into left and right regions. The region where the screen 2D coordinates and center point coordinates are located is determined by the x-coordinate value. If the x-coordinate of a certain coordinate is greater than the x-coordinate of a point on the first line, the point corresponding to that coordinate is located on the right side of the first line; if the x-coordinate of a certain coordinate is less than the x-coordinate of a point on the first line, the point corresponding to that coordinate is located on the left side of the first line. To ensure that the lines between 3D annotated measurement points and measurement point detail pages do not intersect, the number of 3D annotated measurement points and measurement point detail pages in each partition of the left and right regions is the same; otherwise, the cross-regions will intersect.

[0049] The remaining screen 2D coordinates are iterated through to the number of 2D coordinates on the left and right sides of the first connecting line, and the remaining center point coordinates are iterated through to the number of center point coordinates on the left and right sides of the first connecting line. The results are then compared to determine whether the number of 2D coordinates and center point coordinates in the left region of the first connecting line are the same, and whether the number of 2D coordinates and center point coordinates in the right region of the first connecting line are the same. The results are then used to determine the target center point coordinates that match the target 2D coordinates.

[0050] Furthermore, if the number of two-dimensional coordinates on the same side of the first connecting line is the same as the number of center point coordinates, the coordinates of the first center point are determined as the coordinates of the target center point corresponding to the target two-dimensional coordinates; If the number of two-dimensional coordinates on the same side of the first line is different from the number of center point coordinates, the center point coordinates corresponding to the second inclination angle are determined as the second center point coordinates according to the order of the inclination angles from smallest to largest. Draw the second line connecting the three-dimensional annotation points corresponding to the target's two-dimensional coordinates and the measurement point details page corresponding to the second center point's coordinates; Iterate through the remaining screen 2D coordinates to the left or right of the second line and the remaining center point coordinates to the left or right of the second line. Determine if the number of 2D coordinates on the same side of the second line is the same as the number of center point coordinates. If they are the same, determine the second center point coordinate as the target center point coordinate corresponding to the target 2D coordinate. If they are different, continue to iterate through the center point coordinates corresponding to the remaining tilt angles in ascending order until the target center point coordinate corresponding to the target 2D coordinate is matched.

[0051] If the number of 2D coordinates is the same as the number of center point coordinates, that is, the number of 2D coordinates and center point coordinates are the same in the area to the left of the first connecting line, and the number of 2D coordinates and center point coordinates are the same in the area to the right of the first connecting line, it indicates that the lines between the 3D labeled measurement points and the measurement point details page in each partition of the left and right areas do not intersect. The coordinates of the first center point are then determined as the coordinates of the target center point corresponding to the target 2D coordinates.

[0052] If the number of 2D coordinates differs from the number of center point coordinates, it indicates a mismatch between the 3D labeled measurement points and the measurement point details pages within each partition of the left and right regions. The connection between the 3D labeled measurement point corresponding to the target 2D coordinates and the measurement point details page corresponding to the first center point coordinates is unsuccessful. In this case, a new center point coordinate matching the target 2D coordinates is found. That is, the connection between the measurement point details page corresponding to the desired center point coordinates and the 3D labeled measurement point corresponding to the target 2D coordinates is successful, and the number of remaining 2D coordinates on both sides of the connection is the same as the number of center point coordinates. The center point coordinates corresponding to the second inclination angle are selected; that is, the center point coordinates corresponding to the second inclination angle are selected from the inclination angle arrangement as the second center point coordinates.

[0053] Draw a second line connecting the 3D annotation measurement point corresponding to the target 2D coordinates and the measurement point details page corresponding to the second center point coordinates. Iterate through the remaining screen 2D coordinates on both sides of the second line, and the remaining center point coordinates on both sides of the second line. Determine if the number of 2D coordinates is the same as the number of center point coordinates. If they are the same, determine the second center point coordinate as the target center point coordinate corresponding to the target 2D coordinates. If they are different, continue to select the center point coordinate corresponding to the next tilt angle according to the order of tilt angles. Repeat the above steps until the number of 2D coordinates is the same as the number of center point coordinates, and the target center point coordinate corresponding to the target 2D coordinates is matched.

[0054] The above method only takes finding the center point coordinates that match the screen 2D coordinates as an example. If a center point coordinate is selected first, and then the screen 2D coordinates that match the center point coordinate are found, and the connection between the 3D labeled measurement point and the measurement point details page is drawn, the above method is also applicable.

[0055] Example 2 Figure 3 A flowchart illustrating a method for generating a size report provided in this application embodiment, the method being developed by, for example... Figure 1 The terminal 110 or server 120 in the system shown executes this. In the second embodiment, as... Figure 3 As shown, the method may include the following steps: S310, obtain the screenshot corresponding to each loading page of the 3D measurement point.

[0056] The screenshots are images obtained by extracting the 3D model and 3D annotated measurement points from the dimension report rendered using the dimension report rendering method described in steps S210 to S240 above. Each loading page includes a preset number of 3D measurement points, which can be set according to the user's actual needs, such as 10 or 12. The number of loading pages is determined by the preset number and the total number of 3D measurement points; once the preset number is determined, the 3D measurement points will be distributed across multiple loading pages.

[0057] When the 3D model and 3D annotation points are rendered based on the dimension report rendering method of steps S210 to S240 above, the 3D annotation points of the loading page will be loaded every time the loading page is switched, and the 3D model will be scaled and rotated to an appropriate position to display the 3D annotation points corresponding to the 3D annotation points of the loading page.

[0058] After the user clicks the "Export Report" button, the export process begins. First, the connection between the 3D annotation points and the point details page is hidden. The 3D model and 3D annotation points can be captured as images using `canvas.toDataURL()`, and `setInterval` can be used to quickly flip through all pages and capture all the images. `canvas.toDataURL()` is a method provided by the HTML5 Canvas API, used to convert image data in a Canvas element into a Base64 encoded URL, which can be directly used to display the image on the webpage. `setInterval` is a core timer function used for scenarios requiring repetitive operations.

[0059] S320 generates a dimension report for the 3D measurement points based on a preset report template, screenshots corresponding to each loading page, the measurement point details page corresponding to the 3D annotated measurement points in the screenshots, and the screen 2D coordinates of the 3D measurement points.

[0060] The preset report template is a pre-set template for rendering measurement point detail pages, including table templates and chart templates. When generating the dimension report, an editable document is created for each loaded page, rendering the corresponding screenshot, the measurement point detail page corresponding to the 3D annotated measurement points in the screenshot, and the screen 2D coordinates of the 3D measurement points into its corresponding editable document. After all the information for each loaded page has been rendered in its editable document, the editable documents corresponding to each loaded page are merged to obtain the 3D measurement point dimension report. This dimension report allows for quick searching and locating of specific measurement point information.

[0061] This step specifically includes: determining the target preset report template for rendering the measurement point details page based on the display format of the measurement point details page corresponding to the 3D annotated measurement points in the screenshot; Based on the proportional relationship of the screen 2D coordinates of the 3D annotated measurement points in the screenshot, render the screenshot in an editable document generated based on the loading page corresponding to the screenshot. Based on the target preset report template of the measurement point details page, render the measurement point details page corresponding to the 3D annotated measurement points in the screenshot in the editable document generated based on the corresponding loading page of the screenshot; Draw the connection between the 3D annotated measurement points in the screenshot and the measurement point details page corresponding to the 3D annotated measurement points in the editable document generated based on the loading page corresponding to the screenshot; The editable documents generated from each loaded page are merged to obtain a dimension report, and a download link for the dimension report is generated. The download link is used to open, edit, and search the measurement point information in the dimension report.

[0062] The display format of the measurement point details page includes tables and charts. To ensure the correct rendering of the measurement point details page in the editable document, a report template corresponding to its display format is pre-set. Before rendering, the appropriate template type for the measurement point details page is determined from the preset report templates and set as the target preset report template. The editable document generated based on the screenshot's corresponding loading page can include online editable Word documents, Portable Document Format (PDF) documents, and text documents. This embodiment uses a PDF document as an example to illustrate this step. The PDF document is generated at A4 paper size, and a dedicated area in the middle of the PDF file is designated to display the screenshot content.

[0063] The library used to render the measurement point details page is determined based on the preset report template. Specifically, if the preset report template is a table, the iText library is used to draw the table and render the content of the measurement point details page; if the preset report template is a chart, the JFreeChart library is used to draw the chart and render the content of the measurement point details page. The text content, such as the title of the measurement point details page, is drawn using the iText library. iText is an open-source Java library primarily used for generating PDF documents, supporting the conversion of XML and HTML files to PDF format. JFreeChart is an open-source chart drawing library on the Java platform, written entirely in Java, and designed for use in applications, applets, servlets, and JSP. JFreeChart can generate pie charts, bar charts, line charts, etc. By combining Java with the iText and JFreeChart libraries to dynamically draw elements such as titles, tables, and charts, a PDF document suitable for searching and editing can be obtained.

[0064] Based on the proportional relationship between the screen 2D coordinates of the 3D annotated measurement points in the screenshot and their corresponding 3D measurement points within the screenshot, the screenshot is rendered in an editable document generated based on the corresponding loading page. This proportional relationship includes the ratio between the designated area in the PDF document and the screenshot, as well as the ratio between the screenshot and the 2D coordinates of the vehicle's 3D measurement points. The proportion of the vehicle's 3D measurement point's 2D coordinates within the screenshot is calculated based on the screenshot and the vehicle's 3D measurement point's 2D coordinates, thus determining the position of the vehicle's 3D measurement point's 2D coordinates within the screenshot in the PDF document. The ratio between the area occupied by the screenshot and the designated area is determined based on the size of the designated area and the area of ​​the screenshot. The screenshot is then dynamically scaled according to this ratio for adaptive rendering, and the 2D coordinates of the vehicle's 3D measurement points are dynamically updated based on this ratio after scaling the screenshot.

[0065] Following the target preset report template for the measurement point details page, the measurement point details page corresponding to the 3D annotated measurement points in the screenshot is rendered in the PDF document. After rendering the screenshot and measurement point details page in the PDF document, the connection between the 3D annotated measurement points in the screenshot and the corresponding measurement point details page is established using the method described in steps S230 and S240. This completes the generation of each page of the PDF document. All PDF documents are read using the iText library and merged into a unified PDF document using the PdfMerge class. After successful merging, all single-page PDF documents are deleted, resulting in a single PDF document's dimension report. A download link for the dimension report is also generated. The download link returns to the user interface of terminal 110. Users can open an editable and searchable PDF document by clicking the download link and edit or search for the measurement point information of the 3D measurement points through relevant operations. This facilitates quick searching and locating of specific measurement point information, greatly improving the user experience.

Unless explicitly stated in this application, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

The target two-dimensional coordinates are the coordinates with the smallest vertical coordinate value in the screen two-dimensional coordinates. The rendering module 420 is also used to draw the connection between the three-dimensional annotation measurement points corresponding to the target's two-dimensional coordinates and the measurement point details page corresponding to the target's center point coordinates that match the target's two-dimensional coordinates, and to render the dimension report of the three-dimensional measurement points.

[0068] Further, module 430 is specifically used for: determining the inclination angle between the target two-dimensional coordinates and each center point coordinate based on the line connecting the 3D annotation measurement point corresponding to the target two-dimensional coordinates and the measurement point details page; determining the center point coordinates corresponding to the first inclination angle as the first center point coordinates based on the order of inclination angles from smallest to largest; drawing the first line connecting the 3D annotation measurement point corresponding to the target two-dimensional coordinates and the measurement point details page corresponding to the first center point coordinates; iterating through the number of remaining screen two-dimensional coordinates to the left or right of the first line, and the number of remaining center point coordinates to the left or right of the first line; and determining the target center point coordinates that match the target two-dimensional coordinates based on the number of two-dimensional coordinates and the number of center point coordinates on the same side of the first line.

If they are the same, determining the second center point coordinate as the target center point coordinate corresponding to the target two-dimensional coordinate; if they are different, continuing to traverse the center point coordinates corresponding to the remaining tilt angles according to the order of tilt angle from smallest to largest until a target center point coordinate corresponding to the target two-dimensional coordinate is matched.

[0070] Furthermore, the rendering module 420 is specifically used to: after drawing the pairing line between the first screen two-dimensional coordinate corresponding to the target two-dimensional coordinate and the measurement point details page corresponding to the target center point coordinate that matches the target two-dimensional coordinate, based on the remaining screen two-dimensional coordinates on the left and right sides of the pairing line, return to the step of determining the target two-dimensional coordinate and the target center point coordinate that matches the target two-dimensional coordinate in the screen two-dimensional coordinate, until the last screen two-dimensional coordinate corresponding to the target two-dimensional coordinate and the measurement point details page corresponding to the target center point coordinate that matches the target two-dimensional coordinate are drawn, thus completing the rendering process of the three-dimensional measurement point dimension report.
