Abstract
A method for regulating the attitude of a motor vehicle by measuring the characteristic angles of the wheels, includes the following operations: obtaining at least one pair of images of each moving wheel while the vehicle is being positioned on the measuring site; calculating for each image the ellipse resulting from the interpolation of a discrete number of points lying on the image; establishing a correspondence between the points identified in each pair of images, to uniquely determine the edge of the wheel rim and its spatial position; calculating the value of the characteristic attitude angles relative to the spatial position of the wheel rim.
