摘要: 本文探讨了基于天宝TX8扫描仪、SX10扫描仪,以及Trimble RealWorks (TRW)、Trimble Business Center (TBC)软件的三维激光扫描解决方案在地铁隧道竣工测量中的应用。基于SX10的作业方案具有数据处理效率高、数据精度更加可靠的优势;基于TX8的作业方案具有点云密度大、对CPⅢ控制点数量需求较少的优势。相较于传统基于全站仪的作业方式,本文的两种作业方案均提高了作业效率和数据质量,同时保证了数据的可追溯性。结合贵阳某地铁隧道竣工测量项目验证了该方法的实用性,有效推广了三维激光扫描技术在精密工程测量领域的应用。

Abstract: This paper discusses the application of 3D laser scanning solution based on Trimble TX8 3D scanner, Trimble SX10 3D scanner and Trimble RealWorks (TRW) and Trimble Business Center (TBC) software in metro tunnel completion survey. The operation scheme based on SX10 has the advantages of high data processing efficiency and more reliable data accuracy. The operation scheme based on TX8 has the advantages of high point cloud density and less demand for the number of CPⅢ control points. Compared with the traditional operation mode based on total station, the two operation schemes proposed in this paper greatly improve the operation efficiency and data quality, and ensure the traceability of data. Combined with the acceptance survey project of a subway tunnel in Guiyang, this paper verifies the practicability of the method and effectively popularizes the application of 3D laser scanning technology in the field of precision engineering survey.

Key words: 3D laser scanning, point cloud data processing, subway tunnel, acceptance survey
