Abstract
A method for determining the rolling radius of a wheel, of a motor vehicle on a road surface, including: projecting a light pattern onto the wheel and road surface; recording a light pattern reflected by the wheel and road surface using an image recording device; determining 3D coordinates of points of the reflected light pattern; identifying points of the reflected light pattern of the wheel; identifying points of the reflected light pattern of the road surface; determining the position of the center of rotation of the wheel from the reflected light pattern points identified as belonging to the wheel; determining the position of the road surface from the reflected light pattern points identified as belonging to the road surface; determining the rolling radius on the contact surface of the wheel as the distance between the center of rotation of the wheel and the position of the road surface.
