abstract: There are more and more types of urban rail vehicles and engineering vehicles along
with the rapid development of rail transit. At present, the drawbacks of using clearance cars to check
tunnel gauge encroachment appear more prominent, with unsatisfied efficiency to meet the inspection
requirements. In this thesis, a method for intelligently detecting the intruded degree of subway tunnels
based on 3D laser scanning point cloud data is proposed. With this method, the central axis of
the tunnel can be determined based on the spatial projection method, the point cloud of the tunnel
section profile and the corresponding gauge model are overlaid to compare and analyze in the gauge
reference coordinate system, the boundary detection is realized with the help of the inpolygon function,
at the same time the intruded degree is calculated based on the vector algorithm. As the test results,
the tunnel gauge can be intelligently detected and the detection result map is generated, showing the
subway tunnel gauge detection can be realized quickly and intelligently with the use of 3D laser
scanning technology. Keywords: 3D laser scanning; subway tunnels; gauge detection; overlay analysis
我国城市轨道交通发展越来越快，安全事故频繁
发生，因隧道所产生的各类交通安全事故将对我国人
民生命和财产造成巨大的损失，特别是已建成隧道的
安全运营，将时刻影响着人民群众的生命财产安全。
因此，应重视地铁隧道安全问题
