Abstract

Abstract: With the continuous development of rail transit in our country, urban rail transit has become an important component of public transportation. At present, our country's rail transportation safety monitoring mainly uses equipment such as total stations and station scanners for monitoring, which has the disadvantages of low monitoring efficiency, difficulty in laying monitoring points, and damage to the segment lining. Mobile 3D laser scanning is a new type of rail transit structure safety detection technology. In this paper, the mobile 3D laser scanning technology is used to obtain the data of the complete structure point cloud inside the tunnel. Extract and analyze the mobile 3D laser point cloud, process and analyze the obtained section point cloud so as to obtain the deformation of the ring piece. The experimental results show that the method is not only accurate in obtaining the deformation results of the rings, but also can extract and analyze the rings one by one, which improve the efficiency of the ring monitoring greatly.

Key words: safety monitoring, moving 3D laser, structure point cloud data, ring plate extraction, rail transit
