摘要
针对线型扫描点云数据,本文分析比较了多种压缩算法,提出了一种基于扫描数据线线间关系的曲率压缩新算法,并用VC++编程进行试验分析,取得了较好的压缩效果。
On account of scanning line point cloud data,kinds of reducing methods are analyzed.On the basis of the analysis,a new compressing method of curvature based on the relationship among scanning lines is put forward,which aims at point clouds on scanning lines and is tested on data about Jingang tower.
