摘要
移动激光扫描可快速获取被测物体表面的三维坐标数据,近年来被逐渐应用到轨道交通工程测量项目中。针对当前轨道交通种类繁多而其限界检测研究分散,不利于工程实践的问题,本文提出了一种基于移动激光扫描技术的轨道交通建筑限界一体化检测方案。自主研发了轨道移动激光测量与检测(TLSD)系统,建立系统内部数据采集、处理、分析的限界检测流程,并集成各类现行限界规范标准,可同时满足铁路、地铁等不同轨道交通限界检测的需要。结合某铁路站台进行应用实践,结果显示,TLSD系统具有检测高效、自动化、成果可视化等优势。
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.
