基于激光扫描数据的建筑物信息格网化提取方法

Grid Method on Building Information Extraction Using Laser Scanning Data

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。

Automatically extracting bui research topic in the process of buildi the distribution density of the ＂point new way to extract building in more efficient and it can autom quickly and meet the precision lding information from dense ng reconstruction us cloud＂ of the vehicl formation by using grids is atically extract building info ＂point cloud＂ is a critical ing laser scanning data. Based on e-borne laser scanning system, a proposed. This method is much rmation from dense scanning data requirement of city reconstruction.
