| 摘 要： | 针对闭合条件下地面三维激光扫描点云配准产生的闭合差,基于测量平差理论,提出一种闭合差分配方法.首先通过间接平差理论求出各相邻测站间的坐标转换参数及其精度,再对闭合差按与方差成正比分配给各测站.通过多站点云配准实验,验证了该方法能在一定程度上提高点云配准的精度.

| Abstract: | The existence of point cloud registration error must cause error propagation of multi stations registration.Aiming at the closed error of point cloud registration of terrestrial 3D laser scanning,a distributing approach of closed error based on the theory of surveying error adjustment is proposed.Firstly,the parameters of coordinate transformation and their accuracy of each adjacent station are worked out according to the indirect adjustment theory.Secondly,the closed error is adjusted to each station by va... |
