Paper Abstract

Flange Height and Flange Thickness are vital geometric parameters for train wheels. Usually, they are manually measured by wheel vernier after the train stops. In this paper a new inspection system is introduced, slit laser is projected onto tread of wheel while the train is in motion, and CCD cameras record light-section images of wheel profile. Geometric parameters and profiles of wheel are measured on the basis of image processing. This paper introduces the measuring principle of this inspection system and arithmetic to draw-out curves of wheel profile, and emphasizes on improved image processing arithmetic for profile images discontinued by abnormities. Those arithmetic are validated by images get from CRH EMU Depots.
