Abstract
A method of inspecting an automotive wheel includes providing an inspection station having a light source for illuminating the wheel, and a camera having a zoom lens. The automotive wheel is positioned in the inspection station and the wheel is illuminated to generate a first image including the reference feature. After the first image information has been delivered to the processor, the model of the automotive wheel is determined on the basis of data stored in the processor and the parameters to be used during the inspection of the particular model are employed in the subsequent inspection. The processor determines the position of the reference feature and determines whether the automotive wheel is in the desired position. If not, the wheel is rotated to move the reference feature toward the desired position. The light source, camera and zoom lens are then moved to a second position closer to the reference feature and a zoomed second image of the automotive wheel is obtained with the image second information being compared in the processor with the desired reference position location. If the reference feature is not in the desired position, the processor initiates further rotation…
