1. A wheel alignment apparatus for determining the alignment of the wheels of a vehicle, said apparatus comprising:

  • a set of predetermined optical targets adapted to be mounted in positions to provide images functionally related to wheel alignment parameters;

    at least one video camera disposed to receive images of said optical targets, each of said at least one video cameras having a field of view;

    a computer operatively connected to said at least one camera, said computer being responsive to the images of said set of targets to determine values of wheel alignment parameters of the vehicle; and

    an elevating mechanism operatively connected to the at least one video camera to raise and lower said at least one camera along a predetermined path, said elevating mechanism being responsive to vertical movement of the vertically movable surface to move said at least one camera correspondingly along said predetermined path.
