Abstract

A laser measurement system operates to measure portions of a vehicle, such as a vehicle frame. The measurements are used, for example, to determine if the portions of the vehicle are bent or damaged. The measurement system includes a laser scanner and at least one target assembly that can be connected to a point of the vehicle. The laser scanner emits a laser beam that is detected by the target. Time and laser position information detected by the target are used to determine the location of the target, as well as the location of the point of the vehicle. The location of the point is then compared to an original location of the point to determine if damage has occurred.
