[0045] This application provides an automatic identification method for core modules in building quantity calculation. Figure 1 This is a flowchart illustrating the steps of the automatic identification method for core models in building quantity calculation according to an embodiment of this application, as follows: Figure 1 As shown, the method includes the following steps:

[0046] Step S102: Obtain the CAD drawing of the core mold to be identified;

[0047] Specifically, Figure 2 This is a schematic diagram of a CAD drawing of a large-area core mold according to an embodiment of this application, such as... Figure 2 As shown, the white lines represent the locations of the core molds, demonstrating that the shapes and types of core molds are not entirely consistent across the cross-section of the same building.

[0048] Step S104, extracting the mark layer drawing of the core mold CAD drawing to obtain the name information of the core mold to be identified in the core mold CAD drawing;

[0049] Step S106, extracting the edge line layer drawing of the core mold CAD drawing to obtain the shape information of the core mold to be identified in the core mold CAD drawing;

[0050] Specifically, Figure 3 is a mark layer and an edge line layer schematic diagram of the core mold CAD drawing according to the embodiment of the present application, as Figure 3 indicated, the name information (component identifier) of the core mold to be identified obtained in step S104 specifically refers to XM1 and XM2 in the drawing; the shape information of the core mold to be identified obtained in step S104, such as XM2 in the upper left corner of the drawing, specifically refers to the shape of the core mold composed of the white rectangle in the drawing.

[0051] Step S108, obtaining the name information and the shape information of the preset core mold in the preset requirement;

[0052] Specifically, the shape information of the preset core mold includes a rectangle, an edge arch shape, a strip shape, a shear tooth shape, a thin-walled box shape, a large arch box shape and the like.

[0053] Optionally, after step S108, it is judged whether the name information of the core mold to be identified is obtained;

[0054] If there is no name information of the core mold to be identified obtained, it is set whether to identify the core mold to be identified, if yes, the core mold to be identified in the core mold CAD drawing is matched and identified according to the shape information of the core mold to be identified and the shape information of the preset core mold, if no, the core mold to be identified without the name information obtained is not matched and identified; if there is no core mold to be identified without the name information obtained, step S110 is continuously executed.

[0055] It should be noted that the above option is for the information extraction of the core mold CAD drawing to be identified, and there is a case of "extracting the shape but not the name". If the engineering is roughly done and the engineering quantity is not large, the non-default conversion can be performed to identify the core mold without the name extracted; if the engineering is completely accurate and the positions without the mark are remembered, the default conversion is not performed (only the core mold to be identified with the name extracted is identified), and the flexibility of large-scale core mold identification is increased after manual setting.

[0056] Step S110, matching and identifying the core mold to be identified in the core mold CAD drawing according to the name information and the shape information of the core mold to be identified and the name information and the shape information of the preset core mold.

[0057] Specifically, a maximum recognition perimeter of the core mold is set, and a recognition order is set; under the constraint of the maximum recognition perimeter, the core mold CAD drawing is matched and recognized according to the recognition order.

[0058] It should be noted that the core mold CAD drawing design may have errors, such as using the wire frame of the core mold for other frames, which may result in a huge core mold that is obviously impossible in a normal core mold CAD drawing. Therefore, the maximum recognition perimeter of the core mold is set to reduce or avoid errors in the recognition. The recognition order of the core mold can be set according to the type of the core mold in the core mold CAD drawing, such as recognizing A-type core molds first and then recognizing B-type core molds.

[0059] Optionally, after step S108, a three-dimensional core mold is generated at the corresponding position in the core mold CAD drawing that has completed the matching recognition.

[0060] Preferably, a preset construction requirement is obtained, and a three-dimensional core mold is generated on the corresponding hollow floor slab in the core mold CAD drawing that has completed the matching recognition within the area range of the preset construction requirement. For example, a CAD drawing (real size 10*10 meters) is drawn with many core molds, but the actual construction may only need the boards within the real size 5*5 meters construction range, so there is no need to generate core molds outside the range.

[0061] Through steps S102 to S110 in the embodiment of the present application, the problems of low recognition efficiency and low recognition accuracy of core mold arrangement in building quantity calculation are solved, and the core mold is automatically recognized in a large range without manual arrangement, the recognition efficiency is high, and the error is not easy to occur.

[0062] It should be noted that the steps shown in the above process or the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
