Abstract: A method for characterizing the surface over which a vehicle is to be rolled during a rolling compensation procedure. A set of wheel alignment angle sensors are mounted to the rearmost fixed axle of a vehicle which is then backed onto the floor surface to be characterized, and rolled in reverse over the region of the floor surface generally traversed during a rolling compensation procedure. As the vehicle is rolled in reverse, a pair of wheel alignment angle sensors temporarily positioned at selected points on the floor surface measure a distance to the wheel-mounted alignment angle sensors, which in turn, are acquiring camber angle measurements. The resulting set of measurements is stored in an accessible data storage device, characterizing the camber altering contours of a path across the floor surface.

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.
