Automatic dismounting method and equipment for automobile hub nut based on machine vision

The invention relates to an automobile hub nut automatic dismounting method and device based on machine vision. The method comprises the steps that an automobile hub picture or video containing a nut is collected; a target detection algorithm based on deep learning is used to identify hub nut features from the automobile hub photos or videos, and a category prediction frame is marked as a hub nut area, and rough positioning of the hub nut area is completed; the hub nut area obtained through rough detection is subjected to fine detection, and fine positioning of the center of the hub nut is completed; the position, obtained through fine detection, of each nut in the original automobile hub image is transmitted to a mechanical arm; and through a mechanical arm, the corresponding nut is aligned according to the position of each nut in the original automobile hub image, and the dismounting action is carried out. Compared with the prior art, the positioning efficiency and accuracy of the automobile hub nut are imp
