【Abstract】 Based on the CCD image measure technique, we propose a untouched online system of measuring the geometrical size of train wheel. The structure and principle of the system is given. The illumination of subsystems, the position of visions and methods of image processing are discussing in detail. Finally an online comparison is carried out using the proposed system.更多还原
