Method and device for regulating the attitude of a motor vehicle
First Claim
1. A method for regulating the attitude of a motor vehicle by measuring the characteristic angles of the wheels, comprising the following operations:
- obtaining at least one pair of images of each moving wheel while the vehicle is being positioned on a measuring site;
calculating for each image the ellipse resulting from an 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 an edge of the wheel rim and a spatial position of the wheel rim; and
calculating the value of the characteristic attitude angles relative to the spatial position of the wheel rim.
