Abstract:
1. A vehicle wheel alignment apparatus for determining the alignment of one or more wheels of a vehicle, said apparatus comprising: at least one optical target adapted to provide images functionally related to vehicle wheel alignment parameters, said at least one optical target having at least one brightness gradient disposed on at least one target face, said brightness gradient including three or more regions, each having a discrete brightness characteristic; at least one camera disposed to generate at least one image of said at least one optical target, said camera configured with an imaging device sensitive to detect said at least one brightness gradient; and a computer operatively connected to said at least one camera, said computer configured to receive and process said at least one image of said optical target to determine one or more optical target parameters; and said computer configured to utilize said one or more optical target parameters to calculate one or more vehicle wheel alignment angles.
