摘要
简单介绍了三维激光扫描的技术原理,同时以实际工程为例详细探讨了其在地铁隧道调线调坡测量中的应用。经对比分析,结果表明该技术的应用是可行的,且精度能够满足相关规范要求。同时因其高度自动化的作业模式,不但可以大大提高测量的作业效率,而且扫描获取的点云数据,可以为后续的大量工作提供数据基础,避免重复繁杂的数据采集工作,具有广阔的应用前景。
In this paper,the principle of 3 d laser scanning technology is briefly introduced,and the application of 3 D laser scanning technology in route and gradient adjustment measurement of subway tunnel is discussed in detail by taking practical engineering as an example.The results show that the application of this technology is feasible,and the accuracy can meet the requirements of relevant specifications.At the same time,due to its highly automated operation mode,this technology not only can greatly improve the efficiency of measurement,but also the point cloud data obtained by scanning can provide a data basis for a large number of subsequent work.It avoids repeating complicated data collection work and has broad application prospect.
