Abstract
A noncontact position and orientation measurement system includes at least four beacons disposed on a first object. Each beacon is operable to generate an optical signal. The system also includes a beacon controller operable to sequentially activate and deactivate each of the beacons. The system also includes an electro-optical sensor disposed on a second object. The electro-optical sensor is operable to generate an output signal for each optical signal received from the beacons. The system further includes a signal con-roller coupled to the electro-optical sensor. The signal controller is operable to determine a position and an orientation of the second object relative to the first object using the output signals generated by the electro-optical sensor.
