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.
In order to explore the influence of the change of scanning station setting on the accumulation of point cloud registration errors, the propagation characteristics of point cloud registration errors are studied, and the model of point cloud registration error propagation is given.According to the experimental point cloud data, The final error of point cloud registration under different set number of stations is determined by comparing the error to determine the optimal number of multi-view cloud registration set station is 4. The determination of the optimal number of station setting For reducing the transfer of registration error, It is of great importance to improve work efficiency.
