Abstract: Using computer vision theory,image coordinate system and camera coordinate system are set up.On the basis of two projected pictures from automobile wheel at the volley and theory of coordinate transformation for points in space,its equation of motion for corresponding point image is derivated,and the mathematical model based on this theory to solve the automobile wheel motion parameter is set up .On the basis of the method,the paper sets up experiment system of alignment test and proves its practiability.

Key words: computer vision, automobile alignment, test method
