摘　　要：由于测绘科技的飞速发展,三维激光扫描技术在测绘领域的应用日益广泛,但目前还没有通用的三维点云配准误差传播模型,且均未广泛应用到三维激光扫描领域。为此,本文通过引入摄影测量学原理对各测站点云的配准进行分析,探讨了三维激光点云配准误差传播的规律,并将传统控制测量的方法应用到激光扫描测绘中,并优化完善了误差传播模型。通过实验,验证了点云配准过程中配准精度与多站配准误差积累的定量关系,从而对点云配准质量进行评估预测。Due to the rapid development of mapping technology,three-dimensional laser scanning technology in the field of surveying and mapping applications are increasingly widespread,but the three-dimensional point cloud registration error propagation model has not yet unified,and not widely used in three-dimensional laser scanning.In this paper,the registration of the point cloud is analyzed by introducing the principle of photogrammetry.The propagation law of the three-dimensional laser point cloud registration error is discussed,and the traditional control measurement method is applied to the laser scanning surveying and optimized Perfect the error propagation model.Through the experiment,the quantitative relationship between the registration precision and the accumulation of multi-station registration error is verified,and the quality of the point cloud registration is estimated and the precision of the station can be controlled.
