Abstract: A vehicle alignment sensor system includes a first sensor assembly for measuring at least a first angle with respect to a fixed reference, that angle being related in a predetermined manner to an alignment angle of a vehicle whose alignment is to be measured, and a second sensor assembly for mounting in a known geometrical relationship to a wheel of a vehicle whose alignment is to be measured. The first sensor assembly has at least one detector, and the second sensor assembly has at least a pair of emitters in fixed geometrical relationship with respect to each other. The detector is capable of measuring the apparent geometrical relationship of the pair of emitters to determine a relative alignment angle of the vehicle, so that a true alignment angle of the vehicle is determinable from the first angle and the relative alignment angle. A calibration method using the present invention is also disclosed.
