摘要 详细介绍三维激光扫描技术的工作原理和所测数据的处理流程,以某矿区开采地表沉降为例,对沉陷区进行了三维激光扫描,采集同时期的11组水准测量数据作为比较。比较结果表明:三维激光扫描所还原的地表沉降信息与反映出的地表沉降趋势,和实际情况相符。另外还分析了三维激光扫描技术在地表沉降监测中存在的数据精度不够的问题和产生误差的原因。本文的研究可为三维激光技术在矿区地表沉陷监测中的应用提供理论支持。 The working principle of the three-dimensional laser scanning technology and the processing flow of the measured data are introduced in detail.Taking the surface subsidence of a mining area as an example,the three-dimensional laser scanning of the subsidence area is carried out,and 11 sets of leveling data of the same period are collected for comparison.The comparison results show that the information of surface subsidence restored by three-dimensional laser scanning is consistent with the actual situation and reflects the trend of surface subsidence.In addition,the problem of inadequate data accuracy and the cause of errors in surface subsidence monitoring by three-dimensional laser scanning technology are also analyzed.It provides theoretical support for the application of three-dimensional laser technology in surface subsidence monitoring in mining area.
