| 摘 要： | 针对地面LiDAR获取的庞大点云数据,提出无人工标志的地面LiDAR点云先局部后整体的配准方法。分割出待配准的两测站重叠区域小块点云,采用基于KD-Tree遍历最近邻域点集的ICP算法计算三维坐标转换参数,实现地面LiDAR点云数据的快速配准。

| Abstract: | The paper presents a registration method from the parts to the whole for terrestrial LiDAR point clouds that have no artificial targets.Overlapping point clouds in two survey stations for registration are segmented.We calculate the three-dimensional coordinate transformation parameters using ICP based on KD-Tree and complete the registration of terrestrial LiDAR point clouds quickly. |
