ABSTRACT:
Apparatus and method for determining the alignment positions and orientations of vehicle wheels includes optical targets mounted on the wheels and optical targets mounted in a fixed relationship with respect to the surface on which the wheels are disposed. Video cameras are used to obtain images of the various optical targets and a computer is responsive to the images of the targets to determine values of wheel alignment parameters of the vehicle relative to said surface on which the vehicle wheels roll. The surface on which the wheels are disposed may be an automotive lift, and apparatus is disclosed for keeping the optical targets in the same position in the field of view of the camera(s) whether the lift is in its rest or in an elevated or reclined position.
