An improved method of slope based filtering of airborne lidar point cloud

YANG Yang,ZHANG Yong-sheng,ZOU Xiao-liang,ZHANG Hao(Institute of Surveying and Mapping,Information Engineering University,Zhengzhou 450052,China)  
Airborne lidar point cloud filtering is the key of acquiring DSM and DEM with high precision. In this paper,several important filtering arithmetics are analyzed,and a new improved segmenting filtering method on the basis of slope based filtering arithmetic is brought out. The results shows that the method can classify the Point Cloud data efficiently.
