摘要
采用三维激光扫描仪与传统观测相结合的方法,获取开采沉陷区精细三维点云数据,在对激光点云数据预处理和数据分析基础上,分别对采空区地表沉降、铁路线沉降、铁路桥沉降与形变监测进行研究,并与传统观测结果进行对比分析,结果表明两者具有较好的一致性。
A new method of mining subsidence monitoring technology is used, which combines 3D laser scanning technology with traditional measurement method to acquire dense 3D laser point cloud data of mining subsidence area. On the basis of point cloud data preprocessing and data analysis, the research includes three aspects, the surface subsidence of mined out space, railway subsidence, and railway bridge subsidence and deformation. Comparative analysis is carried out between 3D laser scanning technology and traditional measurement method.
