基于自适应八叉树分割点云的表面模型重建
SURFACE MODEL RECONSTRUCTION BASED ON POINT CLOUD SUBDIVISION WITH ADAPTIVE OCTREE
摘要
Abstract
In surface model reconstruction with regard to point cloud data,traditional triangulation growth method has very low efficiency because it takes too long time in searching the third vertex.The adaptive octree subdivision algorithm is used in this paper.Point cloud data are divided into subdomains covering each other,and the triangular grids are reconstructed in every subdomain,thus the process of the grid stitching is avoided.The produced triangular grids are optimised using the principle of minimising the maximum angle.A triangular facet orientation method is used for uniformisation of the normal vectors of grids.Experimental results show that the efficiency of the surface model reconstruction is greatly improved by using this method,and the quality of the triangular grids produced are very good as well,the detail features of the model are better reflected,and the algorithm is robust.关键词
