1. A laser measurement system comprising:
- a scanner device including a laser device that generates at least two laser beams; and
a target comprising;
a housing;
electrical circuitry contained within the housing, the electrical circuitry including;
an optical detector that detects when each of the laser beams is directed at the target and detects positions of the laser beams relative to the optical detector; and
a three dimensional position indicator system that visually indicates a relative position of a point on a vehicle frame with respect to a desired position in each of three dimensions, based at least in part on when each of the laser beams is directed at the target and the detected positions of the laser beams relative to the optical detector.

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.
