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.

The invention claimed is: 1. A method for securing an optical target in a non-determined placement relative to a vehicle wheel assembly consisting of a wheel rim and a tire mounted thereon, comprising:abutting a base of said optical target against an outer surface of the vehicle wheel assembly in a non-determined placement between a circumferential lip of the wheel rim and an axial center point of the wheel rim;orienting said optical target such that at least two surfaces, each having a plurality of target elements arranged thereon in geometric and spatial configurations relative to each other, are within a field of view of at least one imaging sensor;coupling at least one attachment mechanism between said base and said vehicle wheel assembly to maintain said base in an immobile position against said outer surface of the wheel assembly during a vehicle service procedure.
