摘要: 针对车载激光扫描点云的分布密度,提出了一种把扫描数据格网化进行信息提取的新方法。实践证明,这种方法效率高,可以自动从密集的扫描数据中快速提取出建筑物信息,能够满足城市三维建模的要求。Abstract: 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.
