Laser measurement of a vehicle frame

A method of operating a laser measurement system, the method comprising:

• detecting a laser beam emitted from a rotating scanner device with a target device, the target device being associated with a position of a part of a vehicle and comprising:
• a housing;
• and
• electrical circuitry contained within the housing, the electrical circuitry including an optical detector that detects when the laser beam is directed at the target device;
• generating data at the target device after the optical detector detects the laser beam;
• and
• wirelessly transmitting the data from the target device to the scanner device.

A target of a laser measurement system, the target comprising:

• a housing;
• and
• electrical circuitry protected by the housing, the electrical circuitry including:
• an optical detector that detects when each of at least two 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.

A laser measurement system comprising:

• a scanner device including a laser device that generates a laser beam;
• and
• a target comprising:
• a housing;
• and
• electrical circuitry contained within the housing, the electrical circuitry including:
