Paper Abstract

This paper proposed a set of practical method for corner detection used for X-ray device calibration. Based on the square steel pattern, the original image is first segmented into several small squares, then edge detection is operated to each small square, after this, Hough transform is used to line approximation and cross points of lines are solved, these cross points are just the corner needed. The experimental results show the proposed method is feasible and robust.
