机载激光扫描测高中激光脚点点群分割新方法

A New Method for Airborne Laser Altimetry Points Cloud Patch Segmentation

讨论了机载激光扫描测高激光脚点点群分割的方法,提出了一种新的分割成片房屋的激光脚点点群的方法———扫描带法,并给出了新方法的算法流程。实践表明,该算法运算速度快,分割准确、可靠。

The method of airborne laser scanning altimetry footprint point cloud patches segmentation is discussed, a new method used to segment the footprint point cloud of group buildings is given, which is called ＂scanning strip method＂. The algorithm and flow chart of the method is demonstrated in detail. The practice shows that the algorithm is efficient, reliable, accurate, and can save great time of segmentation as well.
