Abstract

The invention relates to a method for quickly generating a building floor 3D model in real time. The method comprises the following steps: extracting triangular data in a facade model, and constructing a BVH acceleration structure; acquiring an external facade contour line segment set Se from the BVH acceleration structure; processing the external facade contour line segment set Se, extracting floor contours and nested room contours, and storing the floor contours and the nested room contours into a contour set Sp; detecting a nesting condition between contours in the contour set Sp, and extracting contour data P of an indoor room; and triangularizing the contour data P to obtain a triangular serial number array used for drawing a floor 3D model, and generating a building grid model based on the triangular serial number array. According to the method, the building floor model can be quickly generated in real time under the condition that the external facade model exists, the workload of modeling personnel is greatly reduced, real-time operation and quick feedback to users can be realized, and detail adjustment can be performed in time. The invention further relates to a device for quickly generating the building floor 3D model in real time, a storage medium and equipment.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, device, storage medium and equipment for rapidly generating a 3D model of a building floor in real time. Background technique [0002] In the existing digital twin system, a large number of building floor models are used for display, and the generation of the floor models depends on a large number of manual production by professional modelers, the production cycle is long and the process of modifying the display effect is complicated. If it is necessary to mark the indoor room area, additional workload is required to mark the cutting and division of the room model. [0003] If a large number of 3D architectural models rely on manual production, it will take a lot of manpower, and at the same time, the labor cost will also increase greatly, and the low efficiency of manual production cannot meet the current intelligent needs. Therefore, there is an urgent need in this...
