AIRCRAFT SKINS AND WINDOWS MUST NOT HAVE SCRATCHES, AS THEY ARE UNACCEPTABLE FOR COSMETIC AND STRUCTURAL REASONS. MANUAL METHODS ARE INADEQUATE IN GIVING ACCURATE READINGS AND DO NOT PROVIDE A HARD COPY REPORT. A PROTOTYPE SCRATCH MEASUREMENT SYSTEM USING COMPUTER VISION AND IMAGE ANALYSIS HAS BEEN DEVELOPED. THIS PAPER DISCUSSES THE AUTOMATED INSPECTION METHOD, PROTOTYPE AND NEW MODEL DESCRIPTION, THE CALIBRATION METHOD, REPEATABILITY AND REPRODUCIBILITY, AND ERGONOMIC CONCERNS OF THE PREPRODUCTION SYSTEM. THE DESIGN OF THE SCRATCH MEASUREMENT SYSTEM IS FOR USAGE IN THE FACTORY OR AN AIRCRAFT HANGAR. ERGONOMIC CONCERNS ASSURE EASE OF USE BY THE OPERATORS AND PROVIDE A COMPREHENSIVE, ANALYTICAL, AND ACCURATE READING ON AN INSTRUMENT NOT CURRENTLY AVAILABLE.
