直接精简密集点云的三角网格重建
TRIANGULAR MESH RECONSTRUCTION BY DIRECTLY SIMPLIFYING DENSE POINT CLOUD
摘要
Abstract
To address the needs of rapid transmission and to generate the streamlined triangular mesh model directly from dense point cloud,this paper presents an adaptive method for three-dimensional grid division,and gives the reconstruction process of triangular mesh which uses the three-dimensional grid as basic unit.First,by using the macro-estimation method of no difference between points the method obtains the side length of three-dimensional grid,and segments the point cloud data into grid units.Then it selects the data points in basic unit as the seed points,and sets the triangle side lengths to be constrained with approximate positive 6 neighbourhoods to build the initial triangle mesh,and then expands outwardly layer by layer to complete the triangular mesh reconstruction.The advantage of this method is that the reconstruction and simplification processes can be integrated as a whole.Experimental results show that the proposed method is faster with better robustness.关键词
