Three-dimensional pipeline optimization method based on hierarchical bounding box collision detection

The invention provides a three-dimensional pipeline optimization method based on hierarchical bounding box collision detection. The three-dimensional pipeline optimization method comprises the following steps: S1, constructing an AABB bounding box to simulate a real pipeline building scene; s2, designing a collision detection algorithm based on hierarchical bounding boxes, and traversing each hierarchical bounding box to complete preliminary detection and gradual refinement to obtain a pipeline collision detection report; s3, determining a pipeline needing to be adjusted according to the pipeline collision detection report, and optimizing a pipeline design scheme based on the secondary development platform BIM to obtain optimal space distribution and pipeline arrangement; and S4, verifying and evaluating the optimized three-dimensional pipeline scheme. The method has the advantages that the method can be applied to newly-built, rebuilt and rebuilt medium and large buildings, the efficiency of building enginee
