点云配准误差传播规律的研究

Research on Point Cloud Registration Error Propagation

摘要:

引入摄影测量影像匹配的原理，对地面3维激光扫描仪在不同测站采集点云进行配准分析，并在此基础上探讨点云配准误差传播的规律，得出点云配准误差传播的模型.通过点云配准误差实验，验证了点云配准精度与点云模型累积误差的定量关系，从而可为点云配准的质量进行评估.

Abstract:

According to theory of photogrammetry image matching, registration problems about multistation point clouds are analyzed.Then,error propagation rules are discussed in detail and error propagation model for point clouds registration is established.By experiments,the quantitative relationship between precision of point clouds and model accumulation errors is verified,and which can be used to evaluate registration quality of point clouds.
