Chinais vast and the railway geographical environment is complex.It is of great significance to know theclearance state of railway construction for ensuring safe operation.The traditional clearanceinspection method cannot meet the requirements of increasing the speed,intensity and density of railway operation.The clearanceinspection system based on laser scanning can survey the railway building clearance quickly and ac-curately,and managedata.Firstly,the survey coordinate system is established based on the top surface of rail and the center line of rail,and then the clearanceinspection system based on the laser scanning is built through the model and algorithm,finally,the system installed on the platform of GX160 integrated inspection vehicle can be convenient and flexible to detect the railway clearance.
