Alignment
Wheel alignment is part of standard automobile maintenance and consists of adjusting the angles of the wheels so that they are set to the car maker's specification. The purpose of these adjustments is to reduce tire wear, and to ensure that vehicle travel is straight and true (without "pulling" to one side). A camera unit is attached to a specially designed clamp which holds on to each wheel and communicates it's physical positioning with respect to the other camera units to a central computer.
