Abstract
This paper studied the way to measure the vehicle four-wheel alignment parameters according to the theory of machine vision. A new method of obtaining the direction vector of wheel axle was proposed, and the datum pane was established to optimize the mathematical model of four-wheel alignment parameters measurement. The experiments show that this system can gives good performance with sharp image acquisition, high ellipse detection accuracy, and high speed of alignment parameter calculation.
