ABSTRACT:
A method and apparatus for verifying the identity of an observed anonymous target 16 from a plurality of anonymous reflective targets 16 positioned at predetermined spaced apart locations within an area 14 of operation of an automatic guided vehicle 10 is provided. The anonymous targets 16 each have a predetermined width and a predetermined orientation angle. A dead reckoning system 78 and scanner 12 on the vehicle 10 each deliver signals to the onboard computer 52. The onboard computer 52 processes the signals in accordance with preprogrammed instructions and corrects the position and heading of the vehicle 10 based on the sensed position of the reflected electromagnetic radiation delivered from the spaced anonymous targets 16. The onboard computer 52 verifies the identity of the reflecting anonymous targets 16 through an incident and subtended angle analysis which considers the orientation and width of the anonymous targets 16.
