摘要
为探讨扫描仪设站次数的变化给点云配准误差积累造成的影响,研究了点云配准误差传播特性,给出点云配准误差传播的模型.对实验采集的点云数据,计算出不同设站次数下点云配准的最终中误差,通过比较中误差来确定多视点云配准设站的最佳次数为4.设站最佳次数的确定对于减小配准误差传递、提高作业效率具有重要的意义.
To investigate the effect of point cloud registration error accumulation caused by the station number change of terrestrial laser scanner, the error propagation properties of point cloud registration were studied and the model of point cloud error propagation was given. According to the model, the final square error of point cloud registration could be calculated under different station numbers. The optimal station number is four by comparing the square errors of different station numbers. Deterruination of the optimal station number has important significance in respect of registration error decrease and working efficiency improvement.
