Automatic Measurement Technique for Rail- wear Based on Computer Vision

Among all the parameters which display the loss of rail, rail head wear is one of the most primary parameters. When the rail-wear exceeds the limitation, the rail must be replaced or repaired. So, it is very important for the maintenance of the rail and railway security to measure rail-wear precisely and speedily. This paper discusses the application of optical-section method in the automatic measurement system for rail-wear. It illustrates the processes of the system and respective resolution. It is proved in practice that the system possesses characteristics real time, high speed and high precision.
