大型景观测绘中激光扫描的精度控制

A Method to Control the Accuracy of TLS While Surveying in Large Landscape

激光扫描在复杂场景测绘中应用日益广泛,但是,点云配准精度较传统控制测量低。本文研究了将传统的控制测量应用到激光扫描测绘中的方法,可以减少因测站点增多带来的配准误差累计,从而提高点云配准精度,并以颐和园佛香阁三维建模的项目为例,对大型景观测绘中三维激光扫描精度控制的方法进行了研究及应用。

Laser scanner has been widely used in surveying in complex scene,but the precision of registration of point clouds is lower than traditional control survey.In this paper,we apply the control survey to laser scanner：This could reduce the error of registration and increase the precision of registration of point cloud.We take the program of Summer Palace Foxiangge 3D modeling as example,do a research and application on the accuracy of 3D laser scanner in landscape.
