摘要

For the detection of wheel tread of train, the images of the wheel tread are collected by the linear array CCD industrial cameras during the running time of the train.The paper introduces position of the cameras in the detection system and how to select the other parameters.In the paper the deformation of the wheel tread in the image could be calculated according to these parameters, the image can be corrected by the method of gray interpolation.
