[0036] For more information about the data acquisition module, type determination module, and model adjustment module, see Figure 3 The related descriptions will not be repeated here.

[0037] Figure 2 is an exemplary flow chart of a beam model splicing preprocessing method based on a graphic quantity calculation platform according to some embodiments of the present application. Figure 2 As shown, a beam model splicing preprocessing method based on a graphic quantity calculation platform includes the following steps. In some embodiments, a beam model splicing preprocessing method based on a graphic quantity calculation platform can be implemented on a beam model splicing preprocessing system 100 based on a graphic quantity calculation platform.

[0038] Step 210, obtaining a three-dimensional model of the inclined beam. In some embodiments, step 210 may be performed by a data acquisition module.

[0039] In some embodiments, the three-dimensional model of the inclined beam that needs to be preprocessed by the present method may be a three-dimensional model of the inclined beam that needs to be spliced ​​with the three-dimensional models of other components, wherein the three-dimensional model of the inclined beam may be a three-dimensional model of a beam whose end face 330 has an angle with the vertical direction, which is established by graphic quantity calculation software based on engineering-related files (e.g., CAD drawings).

[0040] In some embodiments, the data acquisition module may acquire the three-dimensional model of the inclined beam from the user terminal 130 , the storage device 140 , and an external data source.

[0041] Step 220, determining whether the inclined beam three-dimensional model includes multiple beam segments. In some embodiments, step 220 may be performed by a type determination module.

[0042] In some embodiments, the type determination module may divide the inclined beam 3D model into multiple sub-models, obtain the length direction of each sub-model, and determine whether the length directions of the multiple sub-models are consistent. If they are inconsistent, it can be determined that the inclined beam 3D model includes multiple beam segments; if they are consistent, it can be determined that the inclined beam 3D model is composed of a cube shape and does not include multiple beam segments. For example, the 3D model of the arch beam is composed of multiple cube-shaped beam segment 3D models.

[0043] Step 230: If the inclined beam 3D model does not include multiple beam segments, the inclined beam 3D model is adjusted by projection to obtain a pre-processed inclined beam 3D model 340 for model splicing, wherein the end face 330 of the pre-processed inclined beam 3D model 340 is perpendicular to the XY plane. In some embodiments, step 230 may be performed by a model adjustment module.

[0044] In some embodiments, the model adjustment module may first determine the projection plane 310, project the end face 330 of the inclined beam three-dimensional model onto the projection plane 310, adjust the inclined beam three-dimensional model, and obtain a pre-processed inclined beam three-dimensional model 340 for model splicing. The XY plane may be a plane used to represent the horizontal plane when the graphic calculation software is modeling.

[0045] In some embodiments, the model adjustment module adjusts the inclined beam three-dimensional model by projection to obtain the pre-processed inclined beam three-dimensional model 340 for model splicing, which may include:

[0046] Obtaining the center line of the inclined beam 3D model, wherein the center line is parallel to the length direction of the inclined beam 3D model, and the length of the center line is consistent with the length of the inclined beam 3D model;

[0047] Determine a projection plane 310 based on the center line, and the projection plane 310 is perpendicular to the XY plane;

[0048] Project the end face of the three-dimensional model of the inclined beam onto the projection plane 310 to obtain the end projection section 320;

[0049] Based on the length direction and the length-stretched end projection section 320 of the inclined beam three-dimensional model, a pre-processed inclined beam three-dimensional model 340 is established.

[0050] In some embodiments, the model adjustment module can first obtain the top surface of the inclined beam three-dimensional model, then determine the half-width of the top surface, and generate a center line from the half-width, wherein one end of the center line is located at the half-width, the center line is parallel to the length direction of the inclined beam three-dimensional model, and the length of the center line is consistent with the length of the inclined beam three-dimensional model.

[0051] In some embodiments, determining the projection surface 310 based on the center line includes:

[0052] Project the center line onto the XY plane to obtain the center projection line;

[0053] Obtain the endpoint of the center line corresponding to the end surface 330 of the three-dimensional model of the inclined beam, and use the endpoint as the target endpoint;

[0054] The projection plane 310 is determined based on the target endpoint and the central projection line. The projection plane 310 is perpendicular to the XY plane. The target endpoint is located on the projection plane 310, and the projection plane 310 is perpendicular to the central projection line.

[0055] In some embodiments, the model adjustment module may project the center line onto the XY plane along a vertical direction, and use the projection line of the center line on the XY plane as the center line.

[0056] In some embodiments, the model adjustment module may project the end face 330 onto the XY plane along the vertical direction. It is understandable that the projection point of the end face 330 on the XY plane coincides with an end point of the center line.

[0057] In some embodiments, the model adjustment module can establish the projection surface 310 with the target endpoint as the starting point, perpendicular to the XY plane as the height direction, and perpendicular to the center line and other constraints.

[0058] In some embodiments, the model adjustment module may project the end of the inclined beam three-dimensional model onto the projection surface 310 along the length direction of the inclined beam three-dimensional model to obtain the end projection section 320 .

[0059] In some embodiments, the model adjustment module can use the end projection section 320 as the starting surface and establish a pre-processed inclined beam three-dimensional model 340 based on the length direction of the inclined beam three-dimensional model, wherein an end face 330 of the pre-processed inclined beam three-dimensional model 340 is the end projection section 320, the length direction of the pre-processed inclined beam three-dimensional model 340 is parallel to the length direction of the inclined beam three-dimensional model, and the length of the pre-processed inclined beam three-dimensional model 340 is consistent with the length of the inclined beam three-dimensional model. The pre-processed inclined beam three-dimensional model 340 can be a three-dimensional model of the inclined beam three-dimensional model after the angle of the inclined beam three-dimensional model is adjusted, and the end face 330 is perpendicular to the XY plane, which is used for splicing with other components.

[0060] Step 240: If the inclined beam 3D model includes multiple beam segments, the inclined beam 3D model is adjusted by extending the end beam 410 to obtain a pre-processed inclined beam 3D model 340 for model splicing, and the end surface 330 of the pre-processed inclined beam 3D model 340 is perpendicular to the XY plane. In some embodiments, step 240 can be performed by a model adjustment module.

[0061] In some embodiments, the model adjustment module adjusts the inclined beam three-dimensional model by extending the end beam 410 to obtain the pre-processed inclined beam three-dimensional model 340 for model splicing, which may include:

[0062] Along the length direction of the end beam 410, the end beam 410 is extended by a preset length to obtain an extended end beam model, wherein the extended end beam model may include the end beam 410 before extension and an extended cube 420, wherein the width of the extended cube 420 is the width of the end beam 410 before extension, and the length of the extended cube 420 is the preset length;

[0063] Generate a subtraction cube 430 based on the preset length, the width of the extended end beam model, and the height of the extended end beam model;

[0064] Determine the overlap between the subtracted cube 430 and the extended end beam model;

[0065] The extended end beam model is cut based on the overlapping portion to generate a pre-processed inclined beam three-dimensional model 340.

[0066] In some embodiments, the model adjustment module determines the preset length, which may include:

[0067] Obtaining the cross-sectional height of the end beam 410;

[0068] Obtaining the inclination angle between the end beam 410 and the XY plane;

[0069] The preset length is determined based on the tilt angle and the section height.

[0070] In some embodiments, the end beam 410 may be a beam segment located at the end of the inclined beam three-dimensional model among the multiple beam segments constituting the inclined beam three-dimensional model. In some embodiments, the angle between the length direction of the end beam 410 and the XY plane is the inclination angle. In some embodiments, the cross-sectional height may be the width of the end beam 410.

[0071] In some embodiments, the model adjustment module may determine the preset length based on the tilt angle and the cross-sectional height by the following formula:

[0072] ;

[0073] Wherein, L is the preset length, H is the section height, and a is the inclination angle.

[0074] It can be understood that the extended end beam model is a combination of the end beam model before extension and a cubic extension model, the length of the extension model is a preset length, and the width of the extension model is consistent with the width of the end beam model before extension.

[0075] In some embodiments, the model adjustment module can calculate the length of the subtracted cube 430 by the following formula:

[0076]

[0077] Wherein, dis is the length of the subtracted cube 430, H is the cross-sectional height, and a is the inclination angle.

[0078] In some embodiments, the model adjustment module can establish a subtraction cube 430 with the width of the end beam model as the width of the subtraction cube 430, dis as the length of the subtraction cube 430, and the vertical height of the extended end beam model as the height of the subtraction cube 430. It is worth noting that one side of the subtraction cube 430 is in contact with the end face 330 of the end beam model before extension.

[0079] In some embodiments, the vertical height may be the height difference between the highest point of the end beam model in the vertical (ie, direction perpendicular to the XY plane) upward direction and the lowest point in the vertical (ie, direction perpendicular to the XY plane) upward direction.
