Dynamically inspecting steel rail wear by the laser image system suffers from vibrations on the camera and the laser emitter, which leads to varying extrinsic camera parameters and distorted rail profile, respectively. In the paper, a novel profile calibrating method is presented to address these issues. This method involves a self-calibration of the extrinsic camera parameters, which is based on the coordinate sets projection constructed from the distorted profile to the standard one on quadruple projecting primitives including rail jaw, railhead, rail waist, and foot intersection. To remove ...
