Abstract
Change detection between as-planned building information modeling (BIM) and the as-is point cloud requires significant computational overhead, because it must deal with every geometric face in the BIM and every point in the point cloud one-to-one. To address this problem, our previous study presented an efficient data structure for change detection with a ray-trace algorithm. However, this approach is expected to be problematic when the BIM mesh is sufficiently large that there are special cases wherein its edges do not penetrate among the modifiable nested octree (MNO) nodes that need to be indexed. To make up for this limitation, the current study applied convex polyhedra intersection. The results of our experiments showed that the proposed method overcomes the previous study's BIM mesh indexing problem. Furthermore, it presented a significant computation performance improvement in comparison with the previous approach: 13.6 and 1.1 times faster for two test datasets, respectively.
