Abstract: A machine-vision vehicle service system, and methods of operation, incorporating at least one gimbaled sensor module configured with at least one of a camera, an optical projector, or a range finder to acquire or convey data associated with surfaces in proximity to the vehicle service system for guiding placement of vehicle service components relative to a vehicle undergoing service. The gimbaled sensor module is operatively coupled to a processing system configured with software instructions to selectively control an orientation of the gimbaled guidance system about one or more axis of rotation, enabling observation, projection of visible indicia, or displacement measurement along an associated sensor axis parallel with one of the axis of rotation during vehicle service procedures.

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.

Abstract: A machine-vision vehicle service system, and methods of operation, incorporating at least one displacement sensor to acquire measurements associated with physical floor surfaces in proximity to a vehicle undergoing service or inspection. The acquired measurements are utilized to guiding placement of ADAS target components on a floor surface accounting for deviations from an established vehicle reference plane.

Abstract: A support structure having a vertical element supporting a set of cameras associated with a vehicle measurement or inspection system together with at least one target structure required for realignment or recalibration of onboard vehicle safety system sensors. A camera crossbeam carried by the support structure locates the set of cameras as required to view a vehicle undergoing measurement or inspection. The target structure is affixed to the vertical element of the support structure, at an elevation suitable for observation by at least one vehicle onboard sensors during a realignment or recalibration procedure. A set of rollers facilitates positioning of the target structure on a supporting floor surface during a realignment or recalibration procedure.

Abstract: A system and method for aligning a floor target relative to a vehicle, the floor target including a calibration pattern for observation by a vehicle safety system sensor during calibration. The system includes at least one optical projection system consisting of at least one optical projector having an orientable projection axis. The optical projection system is operatively controlled by a processor to orient said projection axis towards a selected location on the floor surface relative to the vehicle, and to activate the optical projected to illuminate a point, a line, or a boundary, against which the floor target is aligned.

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.
