摘要:
Methods and systems for determining a parameter of a vehicle wheel are provided. The vehicle wheel is mounted on a shaft having an axis of rotation. The method includes projecting a pattern onto the wheel wherein the pattern includes a plurality of discrete optically detectable elements and determining a dimensional parameter of the wheel utilizing at least two of the plurality of discrete elements.
摘要:
Apparatus and method for determining the alignment of a wheel of a vehicle includes mounting a known optical target to a wheel on the vehicle, the known optical target having a plurality of optical elements, each optical element having at least one straight edge disposed on a background, obtaining at least one video image of the optical target, estimating from the video image of the optical target the characteristics in said video image of a plurality of lines corresponding to projections onto the video image of the straight edges of the optical elements, and determining from the estimates of the characteristics the alignment of the wheel. A similar target for determining the position of a runway on which the vehicle is positioned is also disclosed.
摘要:
An improved image sensor for computer systems that use images to calculate vehicle wheel alignments which includes an integrated circuit having a detector array for receiving an image containing vehicle wheel alignment information, an image sensor controller for operating the detector array and directing input/output for external communications outside the circuit, and an internal bus for communications within the integrated circuit. The sensor communicates wheel alignment information contained in the image with the computer system across an interface bus.

摘要:
A vehicle wheel alignment system utilizing a non-contact range finding system in conjunction with one or more optical imaging sensors to acquire images of a fixed target, fixed random object, or the vehicle wheels, from which three-dimensional information related to one or more optical imaging sensor positions or vehicle wheel alignment angles can be obtained.
摘要:
A camera configuration for a machine vision vehicle wheel alignment system which does not dispose all of the cameras on a single rigid structure, such that cameras disposed to view the left side of a vehicle are movable independently of the cameras disposed to view the right side of the vehicle, while maintaining a common reference coordinate system for determining vehicle wheel alignment angles.
