一种基于高程差粗糙度的建筑物激光脚点提取方法
A Building Extraction Method Based on Roughness of Height Difference for Airborne LIDAR Point Cloud Data
摘要
Abstract
The technology of LIDAR has gradually been developed into one of the primary means in obtaining 3D city information in which the building extraction is currently became a research focus and difficulty.In order to do building extraction better,on the basis of analyzing the advantages and disadvantages of existing building extraction methods of airborne LIDAR point cloud data,and combining the height information and filtering information,a method of building extraction based on roughness of height difference was put forward.The experimental result showed that the method had a low demand in data and could get a better result in building extraction.关键词
