基于三维激光扫描的崩滑地质灾害地表监测研究

Deformation monitoring of rockfall and landslide based on 3D laser scanning technology

利用地面三维激光扫描技术提取崩塌滑坡灾害体特征点三维坐标、虚拟断面线,建立三维模型。通过点、线、面综合分析,可获得灾害体的局部细节和整体位移量信息,实现对灾害体的变形监测。研究结果表明,三维激光扫描技术能快速、完整获取变形体变形信息,对灾害体的趋势分析更精确直观,是对传统监测技术的有效补充。

Using Terrestrial 3D laser scanning technology,the 3D coordinates of the feature points,the virtual section profiles, and the three-dimensional surface model are established. Through the comprehensive analysis of points,lines and surfaces,the detail features of the geohazard and the total displacements can be obtained,and the deformation monitoring of the geohazard can be realized. The research results show that the 3D laser scanning technology can quickly and accurately obtain the deformation information,and the trend analysis of the geohazard is more accurate and intuitive. The 3D laser scanning technology is an effective supplement to the traditional monitoring techniques.
