基于车载激光扫描数据的建筑物自动提取算法

Algorithm on Building Extraction based on vehicle- borne laser scanning data

本文针对车载激光扫描点云的分布密度，提出了一种把激光扫描数据格网化进行建筑物提取的新算法。实验证明，该算法可以有效地从密集的激光扫描数据中自动提取出建筑物信息，能够满足三维建模的要求。

Based on the distribution density of the ＂point cloud＂ of the vehicle - borne laser scanning data, a new algorithm to extract building information by using grids is proposed. The experimental results show that, this algorithm can automatically ex- tract building information from dense scanning data efficiently and meet the precision requirement of city reconstruction.
