What should be paid attention to in the detection of automobile wheel hub

The hub of a car is a cylindrical metal part used to support the tire and installed in the center of the axle. It is an important part connecting the brake drum, the wheel and the axle. The center of the hub is the center hole of the hub. There are often four or six threaded holes. An image-based detection method for automobile hub steel sleeves is proposed. Through computer vision detection technology, the steel sleeves are installed at the screw holes of the wheels. , so as to improve the efficiency of production enterprises. In order to locate the position of the hub, preprocess the hub image collected on the production line, detect the position of the hub area and the steel sleeve area, and select an area from the hub center according to the actual installation position of the hub center and the steel sleeve.

Circle detection: Stretch the grayscale image, filter it to obtain circles, obtain candidate circles, cluster the candidate circles, select the candidate circles after clustering, and select the clustering results containing two or more circles . Tags: car hub.
