1. A method for determining distances for measuring a chassis of a vehicle having a body and at least one wheel, comprising: projecting a structured light pattern at least onto the wheel and onto an area of the body surrounding the wheel; recording a light pattern reflected by the wheel with an imaging sensor system for various rotational positions of the wheel; determining a 3-D cloud diagram from the reflected light pattern; determining a center of rotation of the wheel by: adapting a parametric surface model of the wheel to the 3-D cloud diagram for the various rotational positions of the wheel; calculating the wheel normal vector for the respective rotational position of the wheel; and calculating the rotational axis and therefore the center of rotation of the wheel from the spatial movement of the wheel normal vector; determining a point on the body by evaluating the previously determined 3-D cloud diagram; and determining a ride height as a vertical distance between the center of rotation of the wheel and the point on the body.
