摘　　要：针对地面三维激光扫描技术中多视点云数据配准的问题,提出了一种基于控制测量的点云数据配准新方法。该方法的基本原理是:首先借助人工标志完成水平角度、竖直角度以及斜距测量工作;然后利用闭合导线或者附合导线测量原理,计算闭合差,通过分配闭合差,获取高精度的控制点坐标数据;最后按照定向法原理完成点云数据配准工作。利用地面三维激光扫描仪Riegl PLM321进行辅助法数据配准实验,通过对比公共点配准结果表明:基于控制测量的数据配准方法是可行的,它不仅可以满足建模工作的需要,而且克服了传统串联式配准方法中误差累积的弊端。According to the multi-view point data registration problem in Terrestrial 3D Laser Scanner Technology,a new method based on control survey is proposed for point cloud dates registration.The basic principle of this method is firstly by means of planner target to complete measurements of the horizontal angles,vertical angles and slope distance,then calculate the closed error with closed traverse or connecting traverse and then obtain high-precision coordinate data of control points coordinates data by allocating it,finally complete the registration of point cloud data with the orientation method principle.The dates registration based on the auxiliary method by Riegl PLM 321 has been done,and by comparing the common points registration results showed that： The registration method based on control survey is feasible,which could not only meet the needs of the modeling work,and overcome the error accumulation in the tandem registration methods.
