Abstract: A vehicle wheel alignment system utilizing one or more optical imaging sensors to acquire either images gradient brightness optical targets affixed to vehicle wheels, or direct images, of the vehicle wheels, from which three-dimensional information related to one or more vehicle wheel alignment angles can be obtained.

Abstract: An improved image sensing wheel alignment system for calculating vehicle wheel alignments having a detector array for receiving an input image containing vehicle wheel alignment information. An image sensor controller controls the detector array to receive the input image during an acquisition period, the image sensor controller examining signals from the image detecting elements individually at a plurality of times during the acquisition period to determine exposure levels for image detecting elements. An output image from the image detecting elements at the end of the acquisition period contains wheel alignment information for use in calculating vehicle wheel alignments.

Abstract: An improved computer controlled optical imaging vehicle wheel alignment system configured to obtain one or more color images of optical targets associated with a vehicle, and to process the color images to obtain vehicle wheel alignment measurements.
