三维激光扫描技术在隧道断面限界检测中的应用

The application of 3D laser scanning technology in the detection of tunnel section boundary

本文介绍一种利用三维激光扫描技术进行隧道断面限界检测的方法,该方法主要涉及解决两个关键技术问题,即内业处理中如何进行断面点云提取和限界计算。本文针对这两个关键技术问题的解决进行详细的阐述。最后利用该方法与全站仪检测方法的计算结果进行对比,验证该方法的精度可靠性。

This paper introduces a method of demarcation survey for tunnel section with the 3D laser scanning technology.The method mainly involves solving two key technical problems,that is how to extract point clouds of the tunnel sections and calculate the demarcation.The solution of these two key technical problems is described in detail,and finally the obtained results of this method are compared with that of the traditional total station method to verify the accuracy and reliability.
