三维激光扫描的龙柱倾斜观测方法

针对城市高耸建筑物倾斜观测作业时间长、信息量少的问题,将三维激光扫描技术应用到城市高耸建筑物变形监测领域,探讨对无观测标志、不可或不便攀登的城市高耸建筑物进行倾斜观测的施测方法。以龙柱为例,制定了可行的测量方案,并采用高斯曲面拟合算法对其表面进行拟合,精确计算出龙柱的倾斜量,且与全站仪倾斜观测结果进行对比。结果表明,该方法可以快速、全面的获取观测对象的整体信息,且能够满足高耸建筑物倾斜观测的精度要求。

Tilt observation method of dragon post for 3D laser scanning

According to time consuming and less information in the tilt observation of tall buildings,this paper applies three-dimensional laser scanning technology to the field of deformation monitoring,discussing the method of tilt observation tall buildings with no observation signs,unable to climb buildings.Taking the dragon post as an example,the feasible measurement scheme is worked out,and the surface of the dragon post is fitted by using the Gauss surface fitting algorithm,calculate the tilt of the dragon post.Compared with the method of total station,results show that this method can obtain the whole information of the observation object quickly and comprehensively,and can satisfy the accuracy requirement of the tall building tilt observation.
