ABSTRACT:
A laser measurement system indicates the difference between an actual position of a vehicle frame reference point on a vehicle frame and a normal position employing a rotating laser scanner; an electro-optical detector and a host computer. A positioning arrangement is also provided for positioning the electro-optical detector at a known distance from the reference point. In operation, the host computer queries the scanner and detector via a communication link, calculates the actual position of the reference point, and displays the difference between the position of the vehicle reference point on the vehicle frame and the normal position.
