Description

Technical Field

[0001] The present application relates to the field of drawing recognition, and in particular to a plate component recognition method, device, equipment and storage medium. Background Art

[0002] At present, the identification of plate components from architectural drawings is generally based on the digitization of the drawings. After converting the architectural drawings to obtain the element information, the layers are identified and the wall and column lines and beam lines are obtained from the layers where the wall and column lines are located and the beam lines are located. The corner points are identified by splicing the wall and column lines and the beam lines, and then the corner points are connected. The closed area formed by connecting the corner points is used as the plate component in the structural plate plan.

[0003] However, this requires the computation of numerous line segments and the calculation of line intersections and angles. In underground map scenes, there can be hundreds of thousands of line segments, making plate component recognition inefficient. Furthermore, plate components come in a variety of shapes, and the ways in which various line segments intersect are also diverse, making the computation and recognition of corner points difficult. Furthermore, recognition accuracy for irregularly shaped plate components is poor. Summary of the Invention

[0084] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0085] In an embodiment of the present application, a plate member identification method is provided, which can be applied to a server, and of course, can also be applied to other electronic devices, such as terminals (mobile phones, tablet computers, etc.). In an embodiment of the present application, the method is applied to a server as an example for description.

[0086] In the embodiment of this application, Figure 1 As shown in FIG, the method flow of plate component identification mainly includes:

[0087] Step 101: Obtain the graphic element information of each wall column line and each beam line from the architectural drawing.

[0088] The architectural drawings may be in various formats, and the scope of protection of this application is not limited to the specific formats of the architectural drawings. In the embodiments of this application, the architectural drawings are CAD (Computer Aided Design) drawings as an example for illustration.

[0089] In a specific embodiment, obtaining the graphic element information of each wall-column line and each beam line from an architectural drawing includes: identifying, from the architectural drawing, each first layer where each wall-column line is located and each second layer where each beam line is located; and parsing the graphic element information of each wall-column line and each beam line from each first layer and each second layer.

[0090] Graphic primitives refer to basic graphic elements. These include points, line segments, circles, and text. Graphic primitive information can include the location of the primitive in the architectural drawing, as well as the primitive type, such as line segments, circles, and text.

[0091] Step 102 : Generate a target image based on the graphic element information of each wall-column line and the graphic element information of each beam line, wherein the target image includes the outline of each plate component, and each plate component is surrounded by each wall-column line and each beam line.

[0092] In a specific embodiment, Figure 2 As shown, based on the graphic element information of each wall column line and the graphic element information of each beam line, a target image is generated, including:

[0093] Step 201 : Generate a first image based on the graphic element information of each wall-column line and the graphic element information of each beam line, wherein the first image includes a first area enclosed by each wall-column line and each beam line.

[0094] In a specific embodiment, Figure 3 As shown, generating a first image according to the graphic element information of each wall column line and the graphic element information of each beam line includes:

[0095] Step 301: Obtain the outer contour of the first area based on the graphic element information of each wall column line and the graphic element information of each beam line. Figure 4 The figure shown is a schematic diagram of printing the elements of each wall column line and the elements of each beam line in the same image. Figure 4 In the figure, black is the background color, and the white lines are the wall column lines and the beam lines.

[0096] Step 302: Fill the interior of the first region according to the outer contour of the first region to obtain a first image. Figure 5 Shown is a schematic diagram of the first image. Figure 5 In the figure, black is the background color and the white area is the first area after filling.

[0097] Step 202: Generate a second image based on the graphic element information of each wall-column line, wherein the second image includes a second area surrounded by each wall-column line.

[0098] The second image is a binary image that only includes the wall column lines. A binary image is an image in which each pixel is either black or white.

[0099] In a specific embodiment, Figure 6 As shown, the second image is generated according to the graphic element information of each wall column line, including:

[0100] Step 601: Based on the graphic element information of each wall column line, a closed first contour line is obtained from the wall column line, and the area enclosed by the closed first contour line is used as the second area. Figure 7 The figure shows a schematic diagram of the second area. Figure 7 In the figure, black is the background color, the white lines are the closed first contour lines, and the area enclosed by the white lines is the second area.

[0101] Step 602: Fill the interior of the second region according to the closed first contour line to obtain a second image. Figure 8, which is a schematic diagram of the second image. Figure 8 In the figure, black is the background color and the white area is the second area after filling.

[0102] Step 203 : generating a third image based on the graphic element information of each beam line, wherein the third image includes a third area surrounded by each beam line.

[0103] The third image is a binary image that only includes the beam lines. A binary image is an image in which each pixel is either black or white.

[0104] In a specific embodiment, Figure 9 As shown, according to the graphic element information of each beam line, a third image is generated, including:

[0105] Step 901: Generate a fourth image based on the graphic element information of each beam line, wherein the fourth image includes each beam line.

[0106] Step 902: Perform a closing operation on the fourth image to connect the beam lines to obtain a closed second contour line, and use the area enclosed by the closed second contour line as the third area.

[0107] Since the beam lines are parallel lines and not closed, it is necessary to perform a closing operation on the fourth image to connect the beam lines to obtain a closed second contour line.

[0108] Step 903: Fill the interior of the third region according to the closed second contour line to obtain a third image. Figure 10 , which is a schematic diagram of the third image. Figure 10 In the figure, black is the background color and the white area is the third area after filling.

[0109] Step 204: Subtract the second image and the third image from the first image to obtain the target image. Figure 11 The following is a schematic diagram of the target image. Figure 11 In the figure, black is the background color, and the white area is the schematic diagram of each plate component in the target image.

[0110] By subtracting the second image and the third image from the first image, we can obtain the second area surrounded by the wall column lines after removing the filling, and the third area surrounded by the beam lines after removing the filling, and then obtain the images of the segmented plate components. Based on the segmented images of the plate components, the contour information of the plate components can be quickly obtained. Compared with the prior art, which identifies corner points by splicing wall column lines and beam lines, and then connects the corner points, and uses the closed area formed after connecting the corner points as the plate components, which has a large amount of calculation and low efficiency, the present application uses the images of the segmented plate components. Based on the images of the segmented plate components, the contour information of the plate components can be quickly obtained, and the method of geometric splicing is replaced by the method of image operation, which can reduce the amount of calculation and improve the recognition efficiency of the plate components.

[0111] Step 103: Obtain contour information of each plate component according to the target image.

[0112] In a specific embodiment, the contour information of each plate component is obtained based on the target image, including: obtaining each closed third contour line in the target image; calculating the area of ​​the fourth region enclosed by each closed third contour line; based on the area of ​​each fourth region, filtering out interfering contour lines to obtain each closed fourth contour line; based on the closed fourth contour line, obtaining the contour information of each plate component.

[0113] According to the area of ​​each fourth region, the interference contour lines are screened out to obtain each closed fourth contour line. This can be done by judging whether the area of ​​each fourth region is within the preset area range, and using the closed third contour lines corresponding to the fourth regions whose areas are not within the preset area range as interference contour lines, screening out the interference contour lines, and obtaining each closed fourth contour line. The preset area range is pre-set and can be an empirical value or a value obtained from multiple tests. For example, the preset area range can be greater than 0.8 square meters and less than 100 square meters. If the area of ​​the fourth region is not within the preset area range, it means that the fourth region is not a plate component, and may be surrounded by erroneous line segments when the architectural drawings were drawn. Screening out interference contour lines can improve the accuracy of plate component identification.

[0114] In a specific embodiment, the contour information of each plate component is obtained based on the closed fourth contour line, including: obtaining the fifth contour line of the minimum circumscribed rectangle of the closed fourth contour line; obtaining the primitive information within the fifth area surrounded by the fifth contour line; obtaining each closed sixth contour line based on the primitive information within the fifth area; and determining the contour information of each plate component based on the area of ​​the intersection of each closed sixth contour line and the fourth contour line. Figure 12 As shown, it is a schematic diagram of the contour information of each plate component. Figure 12In the figure, black is the background color, white lines are the outlines of each plate component, and the area surrounded by the white lines is each plate component.

[0115] The minimum circumscribed rectangle of the closed fourth contour line may be drawn according to the coordinates of each vertex of the closed fourth contour line.

[0116] The contour information of each plate component is determined based on the area of ​​the intersection of each closed sixth contour line and the fourth contour line. The closed sixth contour line with the largest intersection area can be used as the contour information of the plate component, or the closed sixth contour line with an intersection area greater than a preset value can be used as the contour information of the plate component. The preset value is pre-set and can be an empirical value or a value obtained through multiple experiments. For example, if the preset value is 80%, the closed sixth contour line with an intersection area greater than 80% is used as the contour information of the plate component. This can further improve the accuracy of plate component recognition.

[0117] In summary, the method provided in the embodiment of the present application obtains the graphic element information of each wall column line and each beam line from the architectural drawing, and generates a target image based on the graphic element information of each wall column line and each beam line, wherein the target image includes the outline of each plate component, and each plate component is surrounded by each wall column line and each beam line. The outline information of each plate component is obtained based on the target image. Compared with the prior art, which identifies corner points by splicing wall column lines and beam lines, and then connects the corner points, and uses the closed area formed after connecting the corner points as the plate component, which has a large amount of calculation and low efficiency, the present application generates a target image, obtains the outline information of each plate component based on the target image, and replaces the geometric splicing method with the image operation method, which can reduce the amount of calculation and improve the recognition efficiency of plate components.
