Abstract:

This paper proposes an automated method for extracting road from Mobile Laser Scanning point clouds. Firstly, the scanning lines were extracted from laser scanning point cloud according to GPS time of point. Then, a moving window operator was adopted to filter non-terrain points. Secondly, curb points were detected from terrain points based on curb models. Finally, an algorithm was implemented to track and refine curb points with both global consistency and local similarity properties of road. Experiments were undertaken to evaluate the validities of the proposed method, which proves a promising solution for extracting roads from mobile laser scanning point clouds.

Key words: Mobile LiDAR, point clouds, road extraction, scanning lines, moving windows
