Airborne LIDAR point cloud data filter based on k-d tree

LIU Yan-feng1,WANG Shou-bin2,TANG Zhong-an3,ZHAO Yong-tong1(1.School of Info-physics and Geomatics Engineering,Central South University,Changsha 410083,China;2.Wuhan Zhongzi Survey and Design Co.Ltd,Wuhan 430030,China;3.The Institute of Surveying and Mapping Science & Technology of Hunan,Changsha 410083,China)  
Point cloud data filtering is one of the most important tasks in gaining the high-accuracy Digital Terrain Model(DTM),and the basic principle of filtering is based on elevation abrupt changes in one neighbor area.To great quantity discrete point cloud data,the speed for searching one point's neighbors restricts the efficiency of data filtering.It is possible to quickly find one point's neighbors with k-d tree without prior knowing topological relations of point cloud data which improves the speed for data filtering.
