基于MS60全站扫描仪的隧道断面自动化检测

Automatic Detection of Tunnel Section Based on MS60 Full Station Scanner

传统的隧道断面提取方法各有优势,但也都存在其明显的缺点。全站扫描仪应用于隧道断面的自动检测,不仅有全站仪测点精度高的优点,还有三维激光扫描仪快速扫描海量点云的优势,可以为隧道断面的检测提供理想的解决方案。本文主要研究徕卡MS60全站扫描仪应用于隧道断面自动化检测的方法。首先介绍了全站扫描仪的基本原理,然后阐述了全站扫描仪单点法隧道断面检测和点云法隧道断面检测的主要内容,最后将单点法检测的断面椭圆与点云法检测的断面椭圆进行了对比,从而相互验证两种方法的可靠性。为今后隧道断面自动化检测提供了一些新的思路。

Traditional tunnel section extraction methods have their own advantages,but they all have their obvious shortcomings. The whole-station scanner is applied to the automatic detection of tunnel sections.It not only has the advantage of high accuracy of the total station measuring point,but also has the advantage of a three-dimensional laser scanner to rapidly scan massive point clouds,and can provide an ideal solution for the detection of tunnel sections.This article focuses on the method used by the Leica MS60 station scanner for automatic detection of tunnel sections. Firstly introduced the basic principle of the station scanner,and then elaborated the main content of the single point method of the tunnel scanning of the whole station scanner and point cloud detection tunnel section detection.Finally,the cross-section ellipse detected by the single-point method is compared with the ellipse detected by the point cloud method to verify the reliability of the two methods.It provides some new ideas for the automated detection of tunnel sections in the future.
