摘要
主要介绍了地面三维激光扫描技术在地铁隧道竣工测量中的应用。详细介绍了利用三维激光扫描仪外业作业流程、点云数据处理方法。并在广州地铁某在建隧道进行了现场实验,实验结果表明该方法高效、精度高、数据翔实,能够很好地应用于地铁隧道竣工测量,并为地铁后期的施工、运营维护提供详细的基础资料。
This paper describes the application of terrestrial laser scanning technology in the subway tunnel comple-ted Measurement . It describes the workflow of the use of three-dimensional laser scanner in the outside、the point cloud data processing method. And Conducted field tests in Guangzhou subway tunnel under construction,the experimental re-sults show that this method is efficient、high-precision and detailed, it can be well used in subway tunnels completed measurements,and provides detailed basic information for the subway late construction、operation and maintenance.
