| 摘 要： | 地铁主体施工完毕后为了对线路进行调线调坡,需要对地铁隧道进行断面测量,三维激光扫描与常规测量方法相比具有非接触式测量,可高密度采集空间三维点云数据等特点,为地铁断面测量提供了新的途径。本文基于Leica Scanstation 2扫描仪分析了三维激光扫描点云数据采集步骤和数据处理流程,阐述了基于点云数据的地铁断面测量方法,分析了三维激光扫描技术在隧道断面测量中应用的可行性。研究结果表明,这种高密度、高精度的隧道断面能够满足地铁调线调坡等方面的技术要求。

| Abstract: | After the construction of subway main structure , in order to realize route adjustment of alignment and gradient , it needs to survey the profile of subway tunnel .Compared with conventional measuring methods , 3D laser scanning has the characteristics of non-contact measurement and can collect space 3D point cloud data with high density , this provides a new way for the subway profile measurement.Based on the Leica Scanstation 2 scanners this paper analyzed the 3D laser scanning point cloud data collection proce-dures and data processing , expounded the subway profile measurement method based on point cloud data ; analyzed the feasibility of 3D laser scanning technology in the application of tunnel profile measurement .The results show that the profile measured by this meth-od can meet the technical requirements of route adjustment of alignment and gradient . |
