Paper Abstract

The paper researched a detecting system of wheelset based on real time image acquisition and processing. The system used linear laser diode sources to illuminate the wheel treads, and the profiles are obtained by high sensitive CCD. The paper researched the dynamic image acquisition, spatial transformation, image enhancement, image segmentation and measurement algorithms. By analyzing the geometric shape of the wheel tread profile, the parameters such as the flange height, the flange thickness, the angle of flange and the back to back distance can be deduced. Then the wearing degree of the wheel can be calculated, and the more important is that the next maintaining date can be predicted. It's crucial for the safety and stability ofrunning wheelset.
