Abstract: A vehicle service system configured to acquire images of a three-dimensional region of a vehicle wheel assembly tire tread surface. The vehicle service system is configured to process the acquired images to produce a collection of data points corresponding to the spatial position of surface points in the region from which tire tread wear characteristics are identified. The acquired images are further utilized to provide both a graphical and a numerical display to an operator, with the numerical display linked to specifically annotated or indexed points or windows within the graphical display, thereby enabling an operator to quickly identify specific focus points or regions on the tire surface which have been measured at the numerically identified tread depths.

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.

Abstract: A heavy-duty vehicle measurement system utilizing displacement sensor modules disposed in housings on opposite sides of a vehicle inspection lane to acquire a set of displacement measurements associated with a moving heavy-duty vehicle. Displacement data along one or more measurement axes is acquired independently by each of the displacement sensor module to measure corresponding distances between the sensor module and points on a surface of the passing heavy-duty. A processing system is configured to receive and evaluate the set of displacement measurements, together with known parameters of the measurement system, to identify heavy-duty vehicle features, such as configuration, body panels, wheel assemblies, and tire surfaces, and to calculate heavy-duty vehicle parameters such as velocity, wheel rim or tire dimensions, axle relative orientations (scrub angles) and wheel assembly spatial orientations.

Abstract: Calibration targets for use during calibration and inspection of vehicle onboard radar systems. The calibration targets incorporate materials having different radar reflective and transmissive properties to provide distinct radar return signatures, facilitating identification of the calibration targets from among various radar returns associated with surfaces and objects located in proximity to the calibration targets, thereby reducing clear space requirements associated with target placement and positioning during a vehicle service or inspection procedure.
