摘要: 提出了一种基于三维激光扫描技术的高危岩体表面变形监测方法。该方法首先计算第一期点云数据参考点的法向量,并基于此点的法向量构建圆柱体;然后在圆柱体内计算第二期点云数据的区域重心,以此作为危岩体表面两期或多期变形比较的依据。将该方法应用于重庆武隆-南川地区鸡冠岭危岩体的变形监测与分析,获得了初步满意的结果。

关键词: 三维激光扫描, 点云, 变形监测, 圆柱体, 区域重心

Abstract: In this paper, a method of surface deformation monitoring of high risk rock mass based on 3D laser scanning is proposed. Firstly, the normal vector of the reference point of cloud data is calculated and the cylinder is constructed based on the normal vector of this point. And then calculating the regional center of gravity of the second-stage cloud data in the cylinder as the basis for comparing the two or more stages of the surface of the dangerous rock. We apply this method to Chongqing wulong-nanchuan district Jiguanling dangerous rock mass deformation monitoring,which gets a preliminary satisfying result.

Key words: 3D laser scanning, point cloud, deformation monitoring, cylinder, region gravity center
