Abstract

Generally, there always are some surface defects, just like scratch, imprint, surface inclusion etc, in the surface of the strip steel. So it is difficult to determine the edge in the process of strip steel width measurement. Facing this problem, this paper proposes a method of edge detection in the strip steel width measurement. Firstly, the gradient calculation and the non-maximum suppression method are used, and then the statistical decision method is designed to detect the exact position of the strip steel edge. This method has achieved good results in the strip steel edge detection.
