Grid Method on Building Information Extraction Using Laser Scanning Data

Automatically extracting building information from dense “point cloud” is a critical research topic in the process of building reconstruction using laser scanning data.Based on the distribution density of the “point cloud” of the vehicle-borne laser scanning system, a new way to extract building information by using grids is proposed. This method is much more efficient and it can automatically extract building information from dense scanning data quickly and meet the precision requirement of city reconstruction.
