浅述地面三维激光扫描技术及其点云误差分析

Terrestrial laser scanning technology and error analysis of point cloud

近年来,地面三维激光扫描技术的快速发展,使空间数据的获取能力得到了显著提高。地面三维激光扫描技术将使传统的工程测量从静态的单点测量发展到动态的跟踪测量和三维立体测量领域。地面三维激光扫描在土木工程、地形测量、路桥设计、地理数据采集、建筑物变形监测等诸多领域都获得了成功的应用,为城市规划及数字城市等宏观领域的广泛应用提供了条件。本文简单阐述了地面三维激光扫描技术的基本工作原理、点云误差分析及国内外的工程应用实例。

With the rapid development of Terrestrial Laser Scanning,the ability of obtaining spatial data has been significantly enhanced.Terrestrial laser scanning technology enables the traditional measurement from a single point of measurement of static to dynamic tracking and three-dimensional measurement.Terrestrial laser scanning have been successfully applied to civil engineering,topographic survey,road and bridge design,geographic data collection,deformation monitoring of buildings and many other fields and providing comprehensive applications in macroscopical fields like municipal design and digitial city.This paper describes the basic working principle of Terrestrial laser scanning,error analysis of point cloud and examples of engineering applications at home and abroad.
