초록

통계에 따르면 어선의 전복 사고는 전체 전복 사고의 절반 이상을 차지한다. 이는 미숙한 조업, 기상 악화, 정비 미흡 등 다양한 원인으로 발생할 수 있다. 업계 규모와 영향도, 기술 복잡성, 지역적 다양성 등으로 인해 어선은 상선에 비해 상대적으로 연구가 부족한 실정이다. 본 연구에서는 이미지 기반 딥러닝 모델을 활용하여 어선의 횡동요 시계열을 예측하고자 한다. 이미지 기반 딥러닝은 시계열의 다양한 패턴을 학습하여 높은 성능을 낼 수 있다. 이를 위해 Xception, ResNet50, CRNN의 3가지의 이미지 기반 딥러닝 모델을 활용하였다. Xception과 ResNet50은 각각 177, 184개의 층으로 구성되어 있으며 이에 반해 CRNN은 22개의 비교적 얇은 층으로 구성되어 있다. 실험 결과 Xception 딥러닝 모델이 가장 낮은 0.04291의 sMAPE와 0.0198의 RMSE를 기록하였다. ResNet50과 CRNN은 각각 0.0217, 0.022의 RMSE를 기록하였다. 이를 통해 상대적으로 층이 더 깊은 모델의 정확도가 높음을 확인할 수 있다.

Fishing boat capsizing accidents account for more than half of all capsize accidents. These can occur for a variety of reasons, including inexperienced operation, bad weather, and poor maintenance. Due to the size and influence of the industry, technological complexity, and regional diversity, fishing ships are relatively under-researched compared to commercial ships. This study aimed to predict the rolling motion time series of fishing boats using an image-based deep learning model. Image-based deep learning can achieve high performance by learning various patterns in a time series. Three image-based deep learning models were used for this purpose: Xception, ResNet50, and CRNN. Xception and ResNet50 are composed of 177 and 184 layers, respectively, while CRNN is composed of 22 relatively thin layers. The experimental results showed that the Xception deep learning model recorded the lowest Symmetric mean absolute percentage error(sMAPE) of 0.04291 and Root Mean Squared Error(RMSE) of 0.0198. ResNet50 and CRNN recorded an RMSE of 0.0217 and 0.022, respectively. This confirms that the models with relatively deeper layers had higher accuracy.
