Abstract
A method and apparatus for determining the alignment of a vehicle wheel using an optical target attached to the vehicle wheel, the optical target having a dimensionally stable shape and a plurality of visible features defining target elements arranged in a known geometric and spatial configuration relative to each other across at least two surfaces. A two-dimensional image of the optical target is acquired by an imaging system to detect a plurality of target element images corresponding to the plurality of target elements. A spatial orientation of the optical target and an alignment of the vehicle wheel is then determined from the plurality of target element images and the known geometric and spatial configuration of the plurality of target elements on the target surfaces.
