摘要
以危岩体的变形监测为研究对象,以三维激光扫描技术为数据获取方法,阐述了从点云数据到生成深度图像的方法、步骤、注意事项,提出用数字图像处理技术提取特征线,进而对提取的线状特征进行形变分析的方法,为危岩体的变形监测提供了新思路。
The deformation monitoring of unstable rock mass is taken as the study object in this paper,and the 3D laser scanning technology is used as the data acquisition method.It also discusses the methods,steps,and precautions of generating depth image from point cloud data.By extracting the feature line by digital image processing technology,it proposes a method of performing deformation analysis on extracted linear features.This paper provides new ideas for deformation monitoring of unstable rock masses.
