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.

System and method for utilization of displacement sensor during placement of vehicle service fixture

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.

Non-contact inspection system for multi-axle heavy-duty vehicles

A vehicle service system incorporating a pair of gimbal-mounted optical projection systems enables an operator to selectively orient each optical emitter of the optical projection system to illuminate a location on a vehicle surface in proximity to the system. Signals indicative of an orientation of each optical emitter about three-axes of rotation are received at a controller programmed with software instructions to utilize the received signals, together with known locations for the systems, to calculate a three-dimensional coordinate for the illuminated location within an established frame of reference. The controller is further programmed to utilize the calculated three-dimensional coordinate of the illuminated location as an origin point for determining one or more placement locations within the established frame of reference for ADAS sensor calibration or alignment targets.

A machine-vision vehicle service system, and methods of operation, incorporating at least one at least one camera and an optical projector for guiding placement of vehicle service components relative to a vehicle undergoing service. The camera and optical projector are operatively coupled to a processing system configured with software instructions to selectively control a projection axis orientation for the optical projector to enable projection of visible indicia onto various surfaces visible within the field of view of the camera.

System and method for verification of vehicle service target positioning

A method and apparatus for calibrating a projection axis orientation for an optical projector associated with a vehicle inspection or service system so as to enable projection of indicia onto selected spatial locations within a vehicle service area. Projector axis orientations required for the projection of visible indicia onto reference targets disposed at determinable locations within a common coordinate system of the vehicle service area are utilized to establish a relationship utilized to mathematically transform between selected spatial coordinate locations for projected indicia and corresponding orientations of the projection axis, facilitating projection of the visible indicia to additional spatial coordinate locations within the common coordinate system.

Methods for spatial calibration of vehicle ADAS service system

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.

A vehicle measurement station utilizing one or more displacement sensors disposed on each opposite side of an inspection region of a vehicle inspection lane to acquire displacement measurement data along associated measurement axes. At least a portion of the displacement measurement data is associated with the outermost wheel assemblies on an axle of a moving vehicle passing through the inspection region, and utilized to determine one or more vehicle characteristics, such as an axle total toe condition.

Non-contact vehicle measurement system

A vehicle inspection system configured with a processing system and at least one displacement sensor disposed on opposite sides of a vehicle inspection lane sensor region to acquire displacement measurement data associated with a moving vehicle passing through the vehicle inspection lane. The processing system is configured to receive acquired displacement measurement data to determine characteristics of the moving vehicle, such as vehicle velocity, dynamic axle alignment, dynamic wheel alignment, or dimensions. The processing system is further configured to evaluate the determined dynamic vehicle characteristics in relation to static vehicle characteristics, such as static axle alignment or static wheel alignment, through application of one or more compensation factors based on user selected parameters, default parameters, or identified vehicle features.

Method and apparatus for compensating vehicle inspection system measurements for effects of vehicle motion

A method for detecting the occurrence of deviations from level, straight-line rolling movement of a wheel assembly across a supporting surface during a rolling compensation procedure associated with a vehicle wheel alignment measurement or inspection system by identifying changes in measurements or calculated parameters associated with the wheel assembly which would be unchanged during an ideal level and straight-line rolling movement. Identified changes in the measurements or calculated parameters are evaluated to either warn an operator of the occurrence of a deviation, or to generate a correction factor to account for at least a portion of an effect which the deviations introduce into compensation calculations or subsequent wheel alignment measurements or service procedures.

Method for detecting support surface variations during wheel alignment rolling compensation procedure

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.
