Abstract

Aircraft skins and windows must not have scratches, which are unacceptable for cosmetic and structural reasons. Manual methods are inadequate in giving accurate reading and do not provide a hardcopy report. A prototype scratch measurement system (SMS) using computer vision and image analysis has been developed. This paper discusses the prototype description, novel ideas, improvements, repeatability, reproducibility, accuracy, and the calibration method. Boeing's Calibration Certification Laboratory has given the prototype a qualified certification. The SMS is portable for usage in factory or aircraft hangars anywhere in the world.
