Abstract
A wheel alignment system uses head units attached to each of the four wheels of an automotive vehicle. Angle measurements are taken using light sources and light sensors. Pitch sensors measure the pitch of the head units with respect to a horizontal plane. The head units are connected to the left and right front wheels of the automotive vehicle. The pitch information is used to compensate for errors in left and right cross-toe measurements between the left and right front wheels of the automotive vehicle.
