Abstract
A method and apparatus for determining position and rotational orientation of an object within a predetermined area is disclosed. Position markers, encoded with their identity, are viewed with a camera, images are captured and processed, and the position and rotational orientation of the object are calculated. Three embodiments are disclosed; the first having a camera mounted on the movable object while position markers bearing linear bar codes are fixed in location, the second having a camera mounted on the movable object while position markers bearing two-dimensional bar codes are fixed in location, and the third having a position marker of either type affixed to the object while the camera is fixed in location.
