Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of engineering design, and in particular to a method and device for automatic feature recognition of Creo drawings, an electronic device, and a storage medium. Background Art

[0002] In the field of engineering design, Creo software is one of the widely used 3D modeling tools. Designers will mark key dimensions, modification records, modifiers, modification reasons, and other information on the design drawings. When this information needs to be entered into the system and transmitted to downstream systems or other teams, engineers are required to manually identify the important information marked on the Creo drawings and enter it into Excel and databases. If the location information of views, annotations, and tables on Creo drawings exceeds the boundaries, it will not only affect the reading of the drawings, but also cause information leakage when exporting PDF or 2D drawings. In order to avoid this problem, professionals are required to check the drawings one by one, collect the information marked on the drawings, and confirm whether there is any situation that exceeds the boundaries. When the drawing module exceeds the boundaries, the module that exceeds the boundaries needs to be manually typeset.

[0003] Manual recognition is easily affected by subjective factors, has poor accuracy, and has a certain error rate, making it difficult to be completely accurate; manually checking various modules in Creo drawings one by one requires a lot of time and energy, and is inefficient; each recognition requires the participation of professionals, and automation and batch processing cannot be achieved, and the repeatability and consistency of recognition results cannot be guaranteed; professionals are required for manual recognition, which has high labor costs and is difficult to promote and apply on a large scale; manual recognition is slow and cannot meet some application scenarios that require real-time processing.

[0070] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0071] The essence of the technical solution of the embodiment of the present application is explained in detail below with reference to the accompanying drawings.

[0072] Figure 1 A schematic diagram showing a process flow of a method for automatic feature recognition of drawings according to an embodiment of the present application is shown. Figure 1 As shown, the automatic feature recognition method for drawings in the embodiment of the present application includes the following steps:

[0073] Step 101: Acquire feature information of the drawing to be identified;

[0074] In the exemplary embodiment, the engineer first uploads the Creo drawing to be analyzed. After receiving the analysis request, the Creo drawing analysis tool module checks the drawing to be analyzed and the attachments. If the drawing does not meet the regulations or the attachment content does not meet the standards, it is returned to the engineer and an email reminder is sent. The engineer rechecks and re-uploads the drawing. When the uploaded drawing meets all standards, the analysis request is initiated again, the drawing is opened, and the analysis command is activated.

[0075] In an exemplary embodiment, the step of obtaining characteristic information of the drawing to be identified includes: obtaining the number of sheets of the drawing to be identified and the views and tables of all pages. Specifically, the step includes steps 101A to 101D:

[0076] Step 101A: Obtain the number of sheets of the drawings to be identified through the secondary development ProDrawingSheetsCount interface, and traverse the drawings to be identified according to the number of sheets;

[0077] Step 101B: Set the active Sheet value of the current drawing to the traversal value Sheet No.;

[0078] Step 101C: Obtain all view information of the current page through the secondary development of the sketch view interface (ProDrawingViewVisit);

[0079] In the embodiment of the present application, the acquisition of all Views information of the current Sheet through the secondary development of the ProDrawingViewVisit interface includes steps 101C1 to 101C5:

[0080] Step 101C1: traverse all pages to obtain the Views collection of the page;

[0081] Step 101C2: Obtain the dimension information of the current view annotation through the ProDrawingDimensionVisit interface; obtain the dimension information of the current entity annotation through the ProSolidDimensionVisit interface;

[0082] Step 101C3: traverse the acquired dimension information, and obtain the dimension string array information Str[] through the ProDimensionTextWstringsGet interface;

[0083] According to the string array information, the size information, remark information, number information, business information, and modification information marked by the engineer of the current page are obtained. Figure 2 This is a schematic diagram of the dimensions and business information of the drawings of the embodiment of the present application.

[0084] Wherein, the obtaining of the size information, remark information, number information, business information, and modification information marked by the engineer of the current page according to the string array information includes:

[0085] Step 101C4: When the length of the string array information is 1, the string Str[0] is obtained by splitting according to the colon;

[0086] When the length of the split string Str[0] is 1, it means that the current string only has size information;

[0087] When the length of the segmented string Str[0] is 2, it is further determined whether the size information is in the first position or the second position; when the size information is in the first position, the second position is the remark information; when the size information is in the second position, the first position is the number information and other business information;

[0088] When the length of the string after segmentation is 3, the first digit is the number information and business information, the second digit is the size information, and the third digit is the remark information; get the size information, remark information, number information, and business information of the current page;

[0089] Step 101C5: When the length of the string array information Str[] is 2, the size information, remark information, number information, and business information of the current page are obtained through the above rules, and then the modification information marked by the engineer is obtained through Str[1]. The modification information includes addition, deletion, modification, and other information.

[0090] Step 101D: Obtain all the detail table information of the current page through the secondary development ProDrawingTablesCollect interface.

[0091] In the embodiment of the present application, the acquisition of all Tables information of the current Sheet through the secondary development of the ProDrawingTablesCollect interface includes steps 101D1 to 101D3:

[0092] Step 101D1: traverse all pages to obtain the Tables collection of the page;

[0093] Step 101D2: Get the number of rows and columns of the current Table by accessing the ProDwgtableColumnsCount interface and the ProDwgtableRowsCount interface;

[0094] Step 101D3: According to the row number and column number, access the detail table cell value (ProDwgtableCelltextGet) interface through secondary development to obtain the value of each cell.

[0095] Step 102: Analyze the drawing according to the characteristic information of the drawing to be identified to determine whether the drawing is out of bounds;

[0096] In an exemplary embodiment, the step of analyzing the drawing according to the characteristic information of the drawing to be identified and determining whether the drawing is out of bounds includes steps 102A to 102K:

[0097] Step 102A: Traverse all Views of the current Sheet;

[0098] Step 102B: Get the screen transformation matrix (ScreenMatrix) of the current Sheet through the secondary development to obtain the transformation matrix (ProDrawingSheetTrfGet) interface of the sketch;

[0099] Step 102C: Obtain the outline coordinates Point3d[2] of the current traversed View through the secondary development ProDrawingViewOutlineGet interface; in this step, the currently obtained outline coordinates are screen coordinates. If you need to compare with the Sheet outline, you also need to convert the sketch (Drawing) coordinates;

[0100] Step 102D: Convert the screen conversion matrix ScreenMatrix of Sheet into an inverse matrix, specifically including steps 102D1 to 102D5:

[0101] Step 102D1: The function obtains the scaling factor of the input matrix m;

[0102] In the embodiment of the present application, three components x, y, and z are extracted from the first row of the input matrix m and stored in the vec array; the sum of the squares of the three components in the vec array is calculated to obtain the square of the scaling factor scale_sq.

[0103] Step 102D2: Check whether the scaling factor is large enough to ensure that the matrix is ​​invertible;

[0104] In the embodiment of the present application, if scale_sq is less than (1e-9)^2, it means that the matrix is ​​not invertible and the function returns 0.

[0105] Step 102D3: Calculate the square inverse of the scaling factor inv_sq_scale; the square inverse of the scaling factor will be used to calculate the rotation and translation parts of the output matrix.

[0106] Step 102D4: Calculate the rotation part of the output matrix; including:

[0107] Iterate over the first 3x3 part of the output matrix; for each element, divide the corresponding input matrix element by the square of the scaling factor and store in the output matrix; set the 4th column to 0.0.

[0108] Step 102D5: Calculate the translation part of the output matrix; including:

[0109] Traverse the last row of the output matrix; for each element, subtract the element of the corresponding row and column of the input matrix multiplied by the square inverse of the scaling factor, and store it in the output matrix; the last element is set to 1.0.

[0110] Step 102E: Convert the outline coordinates and the inverse matrix into Drawing coordinates through the secondary development specified transformation matrix conversion coordinate (ProPntTrfEval) interface, and obtain the three-dimensional coordinate drawPoint3d[2];

[0111] Step 102F: Get the width and height of the current Sheet through the secondary development interface ProDrawingSheetSizeGet interface;

[0112] Determine whether the drawing is out of bounds based on the three-dimensional coordinates and the width and height of the current Sheet; including:

[0113] Step 102G: If drawPoint3d[0][0]–width>0 or drawPoint3d[0][1]–height>0, the view is out of bounds;

[0114] Step 102H: If drawPoint3d[1][0]<0 or drawPoint3d[1][1]<0, the view is out of bounds;

[0115] Step 102I: If drawPoint3d[1][0]–width>0 or drawPoint3d[1][1]–height>0, the view is partially out of bounds;

[0116] Step 102J: If drawPoint3d[0][0]<0 or drawPoint3d[0][1]<0, the view is partially out of bounds;

[0117] Step 102K: Other cases mean that the view is within the outline of the Sheet and does not cross the boundary.

[0118] Step 103: When the drawing is out of bounds, the position of the drawing is repaired;

[0119] In an exemplary embodiment, when the drawing is out of bounds, repairing the drawing includes steps 103A to 103E:

[0120] Step 103A: Mark the current view with a frame;

[0121] Includes: Get the current window status and refresh the window; define a set of 3D coordinate points, which are calculated based on the drawPoint3d array and the defined X and Y direction offsets. Define the connecting line as a highlight color; use the secondary development image polygon drawing (ProGraphicsPolylineDraw) interface to draw a polygonal figure with these coordinate points; Figure 3 This is a schematic diagram of the view selection result of an embodiment of the present application.

[0122] Step 103B: traverse all views of the current page;

[0123] Step 103C: Get the width view_width and height view_height of each view; where view_width = drawPoint3d[1][0]-drawPoint3d[0][0], view_height = drawPoint3d[1][1]-drawPoint3d[0][1]. Calculate the view area based on the view width view_width and the view height view_height, and sort the views from large to small by view area; to ensure that in the subsequent placement steps, the views with larger areas can be placed first. Because the larger the view, the harder it is to find a suitable position. If we place a view with a smaller area first, it may result in not being able to find a suitable position to place the view with a larger area later. In the embodiment of the present application, the view with the largest area is the first view, the view with the second largest area is the second view, and so on.

[0124] Step 103D: traverse the sorted views and place the sorted views in the current page in order from large to small.

[0125] Specifically, placing the sorted views in the current page in descending order includes steps 103D1 to 103D4:

[0126] 103D1: placing the first view in the first row of the current page and updating the placement position of the first view;

[0127] In this step, if it is the first placement, the moving point is defined as move[0]=10; move[1]=Height-10; move[2]=0; determine whether it is out of bounds based on the module position analysis function. If it is not out of bounds, it means that the current view can be placed, and update the view's position information to the placements list to record the view's position information; if it is out of bounds, continue to try to place the next view.

[0128] 103D2: Determine whether the remaining width of the first row is greater than the width of the second view. When the remaining width of the first row is greater than the width of the second view, place the second view in the first row of the current page, after the first view. When the remaining width of the first row is not greater than the width of the second view, place the second view in the second row of the current page. Update the placement position of the second view. Determine whether it is out of bounds according to the module position analysis function. If it is not out of bounds, it means that the current view can be placed. Update the view's position information to the placement list and record the view's position information. If it is out of bounds, continue to try to place the next view.

[0129] In this step, if it is not the first placement, determine whether width–fistst view_width>second viewwidth is established. When the above conditions are established, define the moving point as move[0]=fistst view_width+20; move[1]=Height-10; move[2]=0; otherwise, wrap and place, and define the moving point as move[0]=10; move[1]=Height–first view_height-10; move[2]=0.

[0130] 103D3: Determine whether the remaining width of the first row is greater than the width of the third view. When the remaining width of the first row is greater than the width of the third view, place the third view in the first row of the current page; when the remaining width of the first row is not greater than the width of the third view, determine whether the remaining width of the second row is greater than the width of the third view. When the remaining width of the second row is greater than the width of the third view, place the third view in the second row of the current page; when the remaining width of the second row is not greater than the width of the third view, place the second view in the third row of the current page; and update the placement position of the third view; determine whether it is out of bounds according to the module position analysis function. If it is not out of bounds, it means that the current view can be placed, and update the view's position information to the placement list to record the view's position information; if it is out of bounds, continue to try to place the next view.

[0131] Step 103D3 is a further analogous step of 103D2, and the moving point is defined in the same way as 103D2.

[0132] 103D4: Use the secondary development view move (ProDrawingViewMove) interface to move the view according to the points defined above, and repeat steps 103D1 to 103D3 until all views are placed.

[0133] In the above steps 1 to 3, after each view is placed, it is necessary to determine whether the placed view is out of bounds. If the placed view is not out of bounds, the placement position of the view is updated, thereby ensuring that the subsequently placed view will not overlap with the already placed view.

[0134] Figure 4 This is a schematic diagram of a drawing after position repair according to an embodiment of the present application.

[0135] Step 104: Export and store the feature information of the drawing and the drawing information after the position repair.

[0136] In an exemplary embodiment, the exporting and storing of the characteristic information of the drawing and the drawing information after the position is repaired includes: exporting the drawing's dimension information, remark information, numbering information, business information, modification information marked by the engineer, and the repaired drawing information to Excel and storing them in a database (DB, Data Base).
