摘　　要：地面三维激光扫描系统可以快速、全面地获取被监测对象的海量三维点云数据,在古建筑三维形变监测领域该技术开始得到应用。通过介绍虎丘塔三维激光点云数据的采集、处理与精度检核方法,以及通过多时相点云数据偏差分析结果对比塔身变化情况,研究了三维激光扫描技术在古建筑形变监测方面的可行性。The Terrestrial Laser Scanning（ TLS） System can obtain massive 3D point cloud data from monitored objects rapidly and comprehensively. It can be applied in field of deformation monitoring for large ancient buildings. In this paper,the method of point cloud data acquisition,registration,and precision analysis for the Tiger Hill Pagoda is presented,and the multi-temporal point cloud data are used to find the tower body changes. The feasibility of applying 3D laser scanning technology in deformation monitoring of ancient architecture is studied.
