摘要: 针对普通多站标靶点云配准方法需进行基于传统测量设备的控制测量问题提出了一种新的多站标靶点云配准方法 该方法使用三维激光扫描仪和卷尺同时完成点云数据的采集和控制测量外业工作并将经典测边网平差理论引入到多站标靶点云配准领域给出了相应误差方程的构建方法 实验结果不仅表明了该方法的有效性而且证明了三维激光扫描技术应用于控制测量的可行性.Abstract: When the multiview tar get point clouds were re gistrated by common al gorithmthe relevantcontrol survey field work is usuall y completed by using traditional measuring equi pment．Aiming atreducing contral survey field worka new multiview tar get point cloud re gistration al gorithm is proposed in this paper．In the new al gorithm the point cloud data collection and control survey field work are completed simultaneousl y using terrestrial laser scanner and ta pe equi pment．The data processing work of re gistratin g a multiview tar get point cloud is accomplished by introducing classical trilateration net ad justment theor y and constructing a new error equation．Experimental results not onl y show the validit y of the proposed alo grithm but also prove the feasibilit y of using terrestrial laser scanner to complete control survey work
