Abstract
The section data of point cloud slices may has the case that the discontinuous feature curve cause the error in fitting.In light of this,we present a method,in which the discontinuous feature curve point set of each section data is divided into continuous feature curve point sets.In view of the Euclidean distances between the discontinuous feature curve point sets and between the points are far greater than the point cloud density,while the Euclidean distance between the points within a continuous feature curve point set approaches the point cloud density,so the point cloud density can be used as a threshold to segment different continuous feature curve point sets.Then the curve fitting is applied to every continuous feature curve points set,and the boundary of the point cloud slices is got.Analysis results show that,this segmentation algorithm can effectively segment the discontinuous feature curve point set in point cloud slices,reduce the error in curve fitting, and improve the extraction accuracy of point cloud slicing boundary.关键词
