Abstract: An image of a wheel hub to which a wheel is mounted is taken by a first camera provided on one side of a vehicle conveyed along an assembly line.  Approximate coordinates of the center of the wheel hub are determined based on the image taken by the first camera.  Second cameras mounted on a wheel-mounting robot are located in front of the wheel and symmetrically with respect to the center of the wheel hub, according to the approximate coordinates of the center of the wheel hub.  Then, revised coordinates of the center of the wheel hub and a rotational displacement of the wheel hub from a standard rotational position thereof, and a turning angle of the wheel hub toward the right or left of the vehicle's progressive direction are determined based on the images obtained by the second cameras.  The wheel is automatically mounted to the wheel hub by the wheel-mounting robot according to these results.
