Claim:
1. A method for evaluating a machine vision vehicle wheel alignment measurement system having a plurality of camera components, each of said camera components having a stationary field of view for observing at least one optical target, comprising: disposing a set of optical targets within overlapping regions of the stationary fields of view for said plurality of camera components such that at least one optical target within said set of optical targets is observable by at least two camera components within said plurality of camera components; observing said set of optical targets with said plurality of camera components to acquire a set of images representative of said observed optical targets, said set of images including, for each observed optical target, at least two images acquired from separate camera components within said plurality of camera components; processing said set of images to identity, for each of said observing camera components, data representative of at least one feature associated with said observed optical targets; comparing said identified data from each of said observing camera components to establish at least one representation of performance for at least a single component of the machine vision vehicle wheel alignment measurement system; and wherein said single component may be an established calibration transform, a camera component, an optical target, a calibration fixture, or a vehicle support surface.
