DURING THE 1990-1991 SCHOOL YEAR AN AUTONOMOUS UNMANNED AERIAL VEHICLE WAS DEVELOPED AT THE GEORGIA INSTITUTE OF TECHNOLOGY TO COMPETE IN THE ASSOCIATION FOR UNMANNED VEHICLE SYSTEMS' FIRST INTERNATIONAL AERIAL ROBOT COMPETITION. THIS HELICOPTER CARRIED TWO ON-BOARD INTEGRATED VISION SYSTEMS (IVS) FOR VEHICLE POSITION DETERMINATION AND TARGET LOCATION. EACH IVS CONSISTED OF A CHARGE COUPLED DETECTOR (CCD) CONNECTED DIRECTLY TO A 68000 BASED MICROCOMPUTER. THIS ALLOWED RAPID IMAGE ACQUISITION AND PROCESSING TO OCCUR ON-BOARD THE VEHICLE, REMOVING THE NEED FOR HIGH BANDWIDTH VIDEO LINKS. REAL-TIME IMAGE PROCESSING ALGORITHMS WERE CREATED TO ALLOW RAPID ADAPTIVE DETECTION OF NAVIGATION LANDMARKS AND TARGETS WITH VARYING INTENSITIES AGAINST CLUTTERED BACKGROUNDS FROM THE MOVING HELICOPTER. THIS PAPER DESCRIBES THE UNIQUE APPLICATION OF THIS INDUSTRIAL VISION SYSTEM TO AIRBORNE NAVIGATION AN
