Train wheels tend to wear abrasion due to frequent startings and brakings. They are important factors of train safety and noise. However, it is difficult and inaccurate to measure their shape and profile manually. Profile measurement system of train wheel with image processing is proposed. The system consists of CCD cameras, PCI image grabber board, and PC operated on Windows"95. Image processing algorithms such as filtering, histogram equalization, and edge detection are presented, and some processing results are illustrated.
