Spectrum data obtained from hyperspectral optical systems were analyzed with a CNN-based deep learning model to detect and identify maritime small objects. The hyperspectral data set for learning was extracted from more than 60 aerial observation images, and classification accuracy was derived by applying a total of 7 CNN models. Among the models used, Inception_v3 was the best at 94.9%, and this result showed more than 10% improvement in accuracy over previous studies conducted with multi-layer perceptron (MLP). If further research breaks down classification items and increases the size of datasets, we expect that the technology will become increasingly utilized in the field of maritime search and surveillance.
