Abstract: Debonding damage of aircraft aluminum honeycomb structure is a common defect type in aircraft composites. With the help of damage image feature edge extraction and noise reduction optimization, the relevant feature information such as damage contour and edge can be extracted, and the optimal extraction scheme can be finally obtained through multi image comparative analysis. According to the obtained damage image edge feature extraction scheme, the edge feature information of aluminum honeycomb structure debonding damage image is extracted, and the above-mentioned scheme is improved to deeply optimize the damage features of honeycomb structure and hence a suitable damage image optimization extraction scheme is found.
