[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0030] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0031] The embodiment of the present application provides a method for batch typesetting of CAD drawings, which is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. Figure 1 As shown, the method includes step S101, step S102, step S103, step S104, step S105, step S106, step S107 and step S108, wherein: S101, obtaining the layout method and number of pieces required by the user and first contour information of multiple current cut pieces to be laid out, and searching for a candidate historical layout that is consistent with the layout method from a preset historical layout library.

[0032] For the embodiments of the present application, typesetting methods include ordinary mixed typesetting, single-piece segmented typesetting, etc., and users can select typesetting methods on the visual operation interface according to their needs. Similarly, it is set on the visual operation interface according to the required number of pieces. After the user draws each cut piece on the electronic device, the electronic device stores the cut piece. The electronic device performs edge detection on the cut piece to obtain the first contour information of the cut piece, and stores multiple historical typesettings corresponding to each mixed method in the local storage medium of the server or the electronic device, that is, a preset historical typesetting library, and each historical typesetting is the typesetting with the least remaining blank area and the most saved printing materials.

[0033] S102 , extracting second contour information of each historical piece from a plurality of historical layouts to be selected, and calculating a first similarity between each current piece and each historical piece based on the first contour information and the second contour information.

[0034] For the embodiment of the present application, similarly, the electronic device performs edge detection on the image of each historical layout to be selected to obtain the second contour information of each historical piece, or each historical layout to be selected corresponds to the second contour information of each historical piece, thereby extracting the second contour information of each historical piece. In order to determine the historical piece closest to each current piece, the electronic device calculates the first similarity between the first contour information of each current piece and the second contour information of each historical piece. Specifically, the calculation of the first similarity can be calculated by the structural similarity metric (SSIM). It can also be calculated by cosine similarity, that is, the image is represented as a vector, and the similarity of the two images is characterized by calculating the cosine distance between the vectors.

[0035] S103, modifying each of the historical layouts to be selected based on the number of items to obtain a modified historical layout to be selected.

[0036] For the embodiments of the present application, the number of items in each historical layout to be selected may be different from the number of items required by the user. Therefore, the electronic device corrects and supplements each historical layout to be selected according to the number of items set by the user. Specifically, the correction can be made through an algorithm or by finding the layout rules in the historical layout to be selected, thereby obtaining a corrected historical layout to be selected. The corrected historical layout to be selected is also the template that saves the most printing materials.

[0037] S104, determining a first number of historical pieces whose similarity of the multiple current pieces reaches a preset similarity threshold in each revised historical layout to be selected, and determining the revised historical layout to be selected whose number reaches the preset threshold as the target historical layout.

[0038] For the embodiment of the present application, assuming that there are 10 current pieces and there are 5 corrected historical layouts to be selected, assuming that the preset similarity is 90%, the electronic device determines the first number of 10 pieces whose similarity reaches 90% in each of the corrected historical layouts to be selected, assuming that 6 of the 10 current pieces reach 90% in the corrected historical layout a to be selected, that is, the first number in the corrected historical layout a to be selected is 6; assuming that 3 of the 10 current pieces reach 90% in the corrected historical layout b to be selected, that is, the first number in the corrected historical layout a to be selected is 6. The first quantity in the candidate historical layout b is 3; assuming that 5 of the 10 current pieces reach 90% in the revised candidate historical layout c, the first quantity in the revised candidate historical layout c is 5; assuming that 7 of the 10 current pieces reach 90% in the revised candidate historical layout d, the first quantity in the revised candidate historical layout d is 7; assuming that 4 of the 10 current pieces reach 90% in the revised candidate historical layout e, the first quantity in the revised candidate historical layout a is 4.

[0039] The more the first quantity of a certain revised historical layout to be selected is, the closer the pieces in the revised historical layout to be selected are to the current pieces, and the more suitable it is to layout the current pieces according to the revised historical layout to be selected. Therefore, a preset quantity threshold is set for the first quantity. Assuming that the preset quantity threshold is 5, the electronic device compares the first quantity of each revised historical layout to be selected with the preset quantity threshold of 5. The preset quantity threshold is used as a dividing point for whether the first quantity is large. Therefore, the revised historical layout to be selected is screened according to the preset quantity threshold, and a revised historical layout to be selected whose first quantity reaches the preset quantity threshold is obtained, that is, the target historical layout.

[0040] S105, determining a target current piece from multiple current pieces whose first similarity with the historical pieces in each target historical layout reaches a preset similarity threshold, and mapping the target current piece on the blank template according to the position of the corresponding historical piece in the target historical layout to obtain an editing template.

[0041] Among them, the blank template is obtained by deleting the historical clips in the target historical typesetting.

[0042] For the embodiment of the present application, in order to better typeset the current clip, the electronic device deletes all historical clips in the target historical typesetting to obtain a blank template. The electronic device retains the position of each clip in the target historical typesetting, and after determining the target historical typesetting, the current clip that reaches the similarity threshold is most suitable for typeset in the target historical typesetting first, so the electronic device maps the target current clip that reaches the similarity threshold in the blank template according to the position of the corresponding historical clip, thereby obtaining an edit template.

[0043] S106, determining the blank area except the target current cutout in each editing template and the overlapping area between the target current cutouts.

[0044] For the embodiment of the present application, after the electronic device maps the target current pieces to the blank template, there may be overlapping areas between the target current pieces, so the electronic device determines the overlapping areas. Similarly, there are blank areas in the edit template, and the blank areas are used to add the remaining pieces in the current piece, so the electronic device determines the blank areas in the edit template.

[0045] S107 , determining a target editing template based on the first number of target current pieces, blank areas, and overlapping areas.

[0046] For the embodiment of the present application, in order to determine the most suitable target editing template from the editing template, the more the first number of selected historical layouts corresponding to the editing template reaches the similarity threshold, the more suitable the editing template is as the target editing template, and the more computing power is saved and faster when mapping and adding the current cut piece. The larger the blank area and the more blank areas, the more suitable it is as the target editing template, and the smaller the overlapping area and the fewer the number of overlapping areas, the more suitable it is as the target editing template. Therefore, the electronic device comprehensively determines the most suitable target editing template based on the first number of the target current cut piece, the blank area, and the overlapping area.

[0047] S108, adding the remaining pieces of the multiple pieces except the target current piece to the target editing template to obtain a final layout.

[0048] For the embodiment of the present application, after the electronic device determines the target editing template, the remaining pieces except the target current pieces are added to the target editing template, thereby obtaining the final layout. By determining a suitable historical layout to be selected from the historical layout, and comprehensively determining a suitable target editing template from the historical layout to be selected in combination with the first number of target current pieces, blank areas, and overlapping areas, and adding the remaining pieces to the target editing template, it is more labor-saving and efficient than manual layout, and reduces the consumption of printing materials.

[0049] In a possible implementation of the embodiment of the present application, in step S107, the target editing template is determined based on the first number of the target current pieces, the blank area, and the overlapping area, specifically including step S1071 (not shown in the figure), step S1072 (not shown in the figure), step S1073 (not shown in the figure), step S1074 (not shown in the figure), step S1075 (not shown in the figure), step S1076 (not shown in the figure), step S1077 (not shown in the figure), and step S1078 (not shown in the figure), wherein, S1071, determining the second number of overlapping regions in each editing template and the overlapping area of ​​each overlapping region.

[0050] For the embodiment of the present application, the electronic device can determine the closed figure formed by the intersection of the first contour information of the cut pieces to obtain the overlapping area, and then count the overlapping areas to obtain the second number of overlapping areas in each editing template. The electronic device counts the number of pixels in each overlapping area to obtain the overlapping area of ​​each overlapping area.

[0051] S1072: Determine an average overlapping area value based on the overlapping area and the second number.

[0052] For the embodiment of the present application, after the electronic device determines the overlapping area of ​​each overlapping region in each editing template, it determines the average value of the overlapping area in each editing template according to the average value calculation formula. The average value of the overlapping area represents the overall overlapping situation in each editing template, that is, the average value of the overlapping area of ​​each overlapping region is used to represent the overall overlapping area.

[0053] S1073, determine the ratio of the first quantity to the second quantity.

[0054] For the embodiment of the present application, after the electronic device determines the first number and the second number, it calculates the ratio of the first number to the second number. The larger the first number, the more suitable it is as a target editing template, and the larger the second number, the less suitable it is as a target editing template. The first number is the numerator and the second number is the denominator. Therefore, the larger the ratio, the more suitable it is as a target editing template, and the smaller the ratio, the less suitable it is as a target editing template.

[0055] S1074, determining the third number of blank areas in each editing template and the blank area of ​​each blank area.

[0056] For the embodiments of the present application, the electronic device determines the closed area formed by the first contour information of each cut piece and the first contour information of other cut pieces as a blank area, the electronic device counts each blank area to obtain the third number of blank areas in each editing template, and the electronic device counts the number of pixels in each blank area to characterize the blank area of ​​each blank area with the number of pixels.

[0057] S1075, determining an average value of the blank areas based on the blank areas and the third number, and correcting the average value of the blank areas based on the first number to obtain a corrected average value of the blank areas.

[0058] For the embodiment of the present application, the electronic device determines the average blank area value based on the blank area of ​​each blank area and the third number of all blank areas, that is, the average area size of each blank area, and uses the average blank area value of each blank area to characterize the overall blank area. Since the number of target current pieces in each editing template is different, the number and area of ​​blank areas in each editing template are different. Therefore, in order to make the subsequent analysis more accurate, the first number of target current pieces in each editing template is used to correct the average blank area value in the editing template to obtain a more reasonable average blank area value, that is, the corrected average blank area value. Specifically, the electronic device may store correction coefficients corresponding to different first numbers, determine the corresponding correction coefficient based on the first number, and use the correction coefficient to multiply the average blank area value or other calculation methods to obtain the corrected average blank area value.

[0059] S1076, determine the aspect ratio of each blank area, and determine the average aspect ratio.

[0060] For the embodiment of the present application, the length in the aspect ratio of the blank area is the line segment with the largest number of pixels in the blank area, and the width is the line segment with the largest number of pixels in the direction perpendicular to the line segment. The ratio of the above two line segments is calculated as the aspect ratio. The aspect ratio represents the degree of applicability of the blank area. The closer the aspect ratio is to one, the closer the blank area is to shapes such as circles and rectangles, and the more types of pieces can be adapted to be added to the blank area. The further the aspect ratio is from one, the narrower and longer the blank area is, and the fewer types of pieces can be adapted to be added. The electronic device calculates the average aspect ratio based on the aspect ratio of each blank area. The average aspect ratio can overall represent the degree of adaptation of the blank areas in the editing template to add pieces.

[0061] S1077, determining a first score for each edit template based on the average overlap area value and the ratio, and determining a second score for each edit template based on the corrected average blank area value and the average aspect ratio.

[0062] For the embodiment of the present application, the average value and ratio of the overlapping area are both key factors affecting whether the editing template is suitable as the target editing template in terms of the overlapping area, and the degree of influence is different. Different coefficients can be set for the average value and ratio of the overlapping area, and then the electronic device performs weighted calculation based on the coefficient and the average value and ratio of the overlapping area to obtain a first score. Similarly, the corrected average value of the blank area and the average aspect ratio are both key factors affecting whether the editing template is suitable as the target editing template in terms of the blank area, and the degree of influence is different. Different coefficients can be set for the corrected average value of the blank area and the average aspect ratio, and then the electronic device performs weighted calculation based on the coefficient and the corrected average value of the blank area and the average aspect ratio to obtain a second score.
