车载激光雷达测量技术在铁路既有线复测中的应用

The Application of on-Board Lidar Measurement Technology in Re-Survey of Railway Existing Lines

采用车载移动激光扫描系统采集测量数据,快速获取铁路周围地形的空间几何信息,很好地解决航空摄影测量经常遇到的复杂地形内的遮挡与盲区问题,为既有铁路测量提供高质量的地理空间数据。论文分析车载移动激光雷达测量系统在某铁路既有线改造工程中的应用,给相关工程提供参考。

Using the on-board moving laser scanning system to collect the survey data,to obtain the spatial geometric information of the terrain around the railway quickly,can solve the common problems in aerial photogrammetry as the problem of occlusion and blind area in the complex terrain,to provide high quality geospatial data for the existing railway survey.This paper analyzes the application of on-board mobile Lidar measurement system in a railway existing line reconstruction,to provide reference for related engineering.
