Abstract: A machine vision vehicle wheel alignment system for acquiring measurements associated with a vehicle. The system includes at least one imaging sensor having a field of view and at least one optical target secured to a wheel assembly on a vehicle within the field of view of the imaging sensor. The optical target includes a plurality of visible target elements disposed on at least two surfaces in a determinable geometric and spatial configuration which are calibrated prior to use. A processing unit in the system is configured to receive at least two sets of image data from the imaging sensor, with each set of image data acquired at a different rotational position of the wheel assembly around an axis of rotation and representative of at least one visible target element on each of the two surfaces, from which the processing unit is configured to identify said axis of rotation of the wheel assembly.

Abstract: A method and apparatus for calibrating laser displacement sensors within a vehicle inspection system. A calibration target structure is positioned within an operative field of view for the laser displacement sensor, providing one or more optical targets onto which illuminating laser beams from the laser displacement sensor are projected. Displacement measurements are acquired with the optical targets disposed at a plurality of positions within the field of view. The resulting displacement measurements, together with known position information for the optical targets, are utilized to calibrate an associated imaging sensor such that the displacement measurements associated with each illuminating laser beam and known positional information agree to within a desired tolerance throughout the operative field of view for the laser displacement sensor.

Abstract: A process for calibrating and evaluating a machine-vision vehicle wheel alignment system having front and rear imaging components associated with each of the left and right sides of a vehicle support structure. Each pair of imaging components defines a front and rear field of view, with a common overlapping region associated with each respective side of the vehicle support structure. Optical targets disposed within each of the overlapping field of view regions are observed by the imaging components to establish performance ratings for the system as a whole, for groups of components within the system, and for individual components within the system.
