Abstract

Abstract: Mobile laser scanning can quickly obtain 3D coordinate data on the surface of the measured object, and has been gradually applied to survey projects of rail transit engineering in recent years. In order to solve the problem that the boundary detection research of different rail transit is scattered, which is not conducive to engineering practice, this paper introduces an integrated detection scheme for clearance gauge of rail transit based on mobile laser scanning technology, develop a track laser scanning and detection(TLSD) system containing a detection process for data acquisition, processing and analysis and current normative standards of clearance gauge, which can be used for the clearance gauge detection of different rail transit. The results of an engineering case show that TLSD system has the advantages of efficient detection, automation, and visualization of results.

Key words: railway monitoring, clearance gauge, mobile laser scanning, point cloud, platform
