Classification of LiDAR object points by fusing aerial image

GONG Liang1,2,LI Zheng-guo1,BAO Quan-fu1(1.Institute of Surveying and Mapping,Information Engineering University,Zhengzhou 450052,China; 2.Jiangxi Province Key Lab for Digital Land,Fuzhou 344000,China)  
Filtering and classification of point cloud is the base of LiDAR data application.A classification method of object point data is put forward in this paper.In this method,fusion of LiDAR data and aerial image is done firstly.Then,the vegetation points are attracted according to their spectrum feature.In succession,building points are classified from the remainder points according to the height texture.Finally,the remained tree points are attracted according to echo information.An experiment is performed with a group of LiDAR data in Beijing.The results presented in this paper have shown that the method is efficient and available.
