| Abstract: | Mobile laser scanning system has become a cost-effective solution for obtaining point clouds of the road surface,building, vegetation,pole,etc.The automatic extraction technique of point clouds is the key to applications of mobile laser scanning system.This paper studies characteristics of road surface point clouds,a progressive mesh method is then adopted to extract road surface point clouds. Experiments show that the proposed method has a desirable solution for road surface data extracting from mobile laser scanning point clouds. |
