ABSTRACT:
Apparatus and methods for determining the deformation of a vehicle body comprising coded targets including coded reflective surfaces positioned in predetermined locations relative to the vehicle body for indicating deformation of the body by determining the spatial position of the targets, a laser generating unit positioned for sweeping a laser beam across the reflective surfaces of the targets, a receiver for receiving the reflected beam, and computer-based, electronic equipment and logic responsive to the receiver for indicating the spatial position of the target means relative to a predetermined normal position with respect to the vehicle body. Apparatus also for determining two and three dimensional spatial coordinates of objects from each other and from a base, utilizing the foregoing components. Additional apparatus comprising portions of the foregoing.
