中文摘要：
获取不同时期三维地表点的空间位置是地面沉降监测的重要内容。三维激光扫描技术在沉降监测工程中可快速获取被测物体表面大量密集点的三维坐标信息,并在此基础上重构被测目标的三维模型。对三维激光扫描仪在地面沉降监测及获取地表三维模型进行了探讨,获取了矿区地表的三维精细模型,从而得到更准确、真实的塌陷区状况,为矿区地表沉降监测提供了新的方法,同时能为管理和决策层提供更加直接和真实的地表目标和研究对象,为矿区土地复垦和生态重建规划提供可靠的数据支持。
英文摘要：
Spatial location acquisition of three-dimensional surface points for different periods is an important content in land subsidence monitoring. In subsidence monitoring project,the three-dimensional laser scanning technology can quickly obtain a large number of in- tensive three-dimensional coordinate information on the surface of the measured objects, and on this basis, to reconstruct three-dimen- sional model of the measured target. In this paper, three-dimensional laser scanner in the land subsidence monitoring was discussed, three-dimensional surface model was also obtained in detail, a more accurate, real destroyed district status of subsidence can be ob- tained,which can provide a new approach for the mining subsidence monitoring,and also provide direct and true ground target and re- search objects to the managers,and provide reliable data to support the mine land reclamation and ecological reconstruction planning.
