Abstract
A mark hole positioning method is provided. The assembly device obtains a target image including a to-be-positioned mark hole, and extracts contour points of the mark hole from the target image. Next, the assembly device generates a circle center set of auxiliary circles by using the contour points as circle centers of the auxiliary circles. Then, the assembly device traverses each circle center in the circle center set and each radius value in a radius set, generates a plurality of auxiliary circles in the target image, and accumulates, for different radius values, a quantity of times of intersection between pixels in the target image and the plurality of auxiliary circles. Finally, sub-pixel positioning information of the mark hole is determined and the mark hole is positioned based on the sub-pixel positioning information of the mark hole.
