摘要： A position determination system comprises a first measuring apparatus and a second measuring apparatus. The first measuring apparatus includes a first sensing device having a sensing field for obtaining positional data of a first testing target, a calibration target rigidly linked to the first sensing device, wherein the positional relationship between the first sensing device and the calibration target is known. The system has a repositioning mechanism for repositioning the sensing field of the first sensing device. The second measuring apparatus includes a second sensing device having a sensing field for obtaining positional data of a second testing target, a calibration sensing device rigidly linked to the second sensing device for obtaining positional data of the calibration target, wherein the positional relationship between the second sensing device and the calibration sensing device is known, and a repositioning mechanism for repositioning the sensing field of the second sensing device. Depending on different needs, the repositioning mechanism readjust the viewing fields of the sensing devices such that the testing targets are properly within the sensing fields of the sensing devices.

摘要： Techniques are disclosed for providing a system that has a plurality of devices in which the position of a device of the plurality of devices relative to another device of the plurality of devices is self-calibrated. In one embodiment, the system is a five-camera aligner for use in aligning motor vehicle wheels. In this embodiment, the aligner includes a first camera pod having two alignment cameras and a calibration camera, and a second camera pod having another two alignment cameras and a calibration target. Because the aligner has four alignment cameras and a calibration camera, the aligner is often referred to as a five-camera aligner. For illustration purposes, the first camera pod is herein referred to as the left camera pod and the second camera pod is herein referred to as the right camera pod. In one embodiment, the left camera pod is placed to the left of the aligner, and the right camera pod is placed to the right of the aligner. The two alignment cameras of the left camera pod focus at the two left wheels of the vehicle under alignment, while the two alignment cameras of the right camera pod focus at the two right wheels of the same vehicle. In addition, the calibration camera on the left pod focuses at the calibration target mounted in the right camera pod. In one embodiment, the relative positions of the elements (alignment camera, calibration camera, and calibration target) in each camera pod are pre-calibrated. Consequently, the aligner is fully calibrated when the position of the left camera pod to the right camera pod is measured. Further, the calibration camera is configured such that it periodically measures the position of the left camera pod relative to the right camera pod, rendering the aligner a self-calibrated aligner.

摘要： A diagnostic system allows a service technician to diagnose a malfunction that occurs during operation of a wheel alignment system after the malfunction has occurred and is no longer apparent. The system, which includes one or more cameras for gathering images of the alignment, gathers information in real time about the alignment of a plurality of wheels. The images include reflections from a target mounted on each wheel, and a processing system in communication with the cameras receives the images and generates analysis data based on them, the analysis data providing an analysis of the alignment of the wheels. A memory device stores the images and the analysis data, and a storage control causes the memory device to store the images and the analysis data in response to activation of the storage control by the operator during the occurrence of the malfunction. A display device in communication with the memory device selectively displays the images and the analysis data, and a play-back control causes the display device to selectively display the images and the analysis data to the service technician in response to activation of the play-back control after the occurrence of the malfunction.

摘要： A wheel clamp attaches to a vehicle wheel for performing a wheel alignment on the vehicle. The wheel clamp has a body for supporting a target or measuring head, and three extendable arms slidably mounted to the body. Each arm has a gripping portion for gripping the tire's tread surface and a sidewall contact portion for contacting the tire sidewall such that the clamp body is substantially parallel to the vehicle wheel and the wheel clamp has no contact with the rim. A self-centering linkage has enmeshed gears and link arms respectively connecting the arms to the gears, such that when the gears are rotated, the arms simultaneously proportionally slide relative to the clamp body, so the gripping portions of the arms engage and grip the tire tread surface and tighten the clamp onto the tire, while the sidewall contact portions of the arms contact the tire sidewall.

摘要： A system for measuring caster trail of a wheel. The system comprises position sensing devices for sensing positional signals of the wheel and a data processing system configured to couple to the position sensing devices. The data processing system receives signals from the position sensing devices and determines spatial characteristics of a steering axis of the wheel, a reference plane and the center of a wheel. The system then determines the caster trail based on the spatial characteristics.

摘要： An apparatus and method for automatically identifying faults in the operation of a machine vision measuring systems provides an improved self-diagnostic capability for machine vision based metrology and tracking systems. The method and apparatus validate performance of tracking operations, and detect deterioration that may be caused by electronic noise, environmental contamination, etc. A mathematical model of the target visualized by the system is created and stored. A target is imaged in the field and fiducials of the target are identified. Centroid positions of detected fiducials of the imaged target are compared to the centroid positions of fiducials in the mathematical model. When a fiducial is obscured or dirty, its geometric characteristics (such as centroid, brightness, edge smoothness, area, or shape) differ from the true or idealized values of the characteristics. Values representing detected fiducials are discarded when the offset exceeds predetermined criteria, or when its properties vary from ideal. If the remaining number of detected fiducials is below a predetermined threshold, a warning message is displayed or an error is generated. Thus, when a fault is detected that degrades performance beyond a preset tolerance, the fault is flagged for attention and a suggested corrective action is displayed.
