Paper Abstract

Wheel set tread defects include scotching and flaking on wheel tread. The paper presents an online measuring method to detect wheel set defects based on optoelectronic technique while the train is running in low-speed within 5-10km/h. Line structure laser illuminates on the wheel tread. High speed CCD cameras were used to gather tread image. Digital image process technique is used to process the data. The measuring device is installed along the straight railway. When the vehicle is running in a limited speed, the devices placed on both sides of the railway can get depth, length and position of possibly existed wheel defects. The measuring accuracy of defects length was 1.0mm.
