Embodiment Construction
[0024] It should be understood that the principles presented herein are not limited in application to the details of construction or the arrangement of parts set forth in the following description or illustrated in the drawings. These principles can be embodied in other embodiments and practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting.
[0025] The present disclosure describes a camera-based locator system that includes added features aimed at improving the safety, flexibility, and functionality of installations. According to one aspect of the present disclosure, a multi-piece support beam is provided for reducing the maximum weight of the camera support beam so that the beam can be more safely handled by a single person.
[0026] According to another aspect of the present disclosure, the locator system is made portable by providing a...

A portable vehicle positioning system is provided having two base tower assemblies, each base tower assembly including footings, a cylindrical tower removably attachable to the top of the footings, and a a camera package that moves along the length of the tower; and a data processor that communicates wirelessly with the wireless communication device to process image data from the camera package. Each camera pack includes a camera for capturing image data of a vehicle-mounted target, and a communication device for wireless communication with the data processor. One of the camera packs has a calibration target and the other camera pack has a calibration camera for capturing images of the calibration target. the footings each have a manually operated clamp for removably fixedly attaching the tower body to the footing in one of a plurality of positions such that the orientation of the camera bag to the footing is angularly adjustable, to allow the camera bag to rotate horizontally.
Description
[0001] related application [0002] This application claims priority to US Provisional Application No. 61 / 867,276, filed August 19, 2013, entitled "Improved Self-Calibrating Multi-Camera Alignment System," which is incorporated herein by reference in its entirety. technical field [0003] Embodiments relate generally to machine vision wheel alignment systems and methods, and more particularly to machine vision alignment systems with movable cameras that continuously self-calibrate their positions relative to vehicle mounted targets. Background technique [0004] Machine vision vehicle positioning systems using movable cameras and targets attached to wheels are known. These targets are viewed by cameras so that image data obtained for a given positioning operation can be used to calculate vehicle positioning angles for display via a user interface, usually a computer monitor. Previous system implementations included rigid beams connecting the cameras so that their position a...
