The invention discloses a hub form-position parameter detection method based on image recognition which comprises the following steps: a digital image of a hub with a calibration template is taken, and the distortion correction coefficient of the digital image is obtained; the digital image of the hub is orderly made grey conversion, image compression and image binarization processing; the binarized image is made an area partition based on the connected area lookup to obtain the effective area of each mounting hole of the hub; the effective area of each mounting hole of the hub is made an edge detection to extract the edge information of the mounting hole to locate the boundary of the mounting hole, meanwhile the boundary of the mounting hole is made a geometric distortion correction; random points on the boundary of the mounting hole is made a sub-pixel interpolatory subdivision to obtain the more accurate boundary of the mounting hole; the circle center and the diameter of each mounting hole are fit according to the random points of the boundary of the mounting hole, and a pitch circle parameter of the hub is fit according to the circle center position of each bolt hole. The method of the invention ensures that the efficiency and the accuracy of the hub detection process are greatly improved and also alleviates the labor intensity of the workers.
