초록

본 논문은 해저지형 영상으로부터 해저산의 중심 위치를 산출할 수 있도록 CNN(convolutional neural network) 기법을 활용한 딥러닝 학습 알고리즘을 제안하였다. 실제 한반도 인근 해역 수심 데이터로부터 약 150장의 해저지형 영상을 생성하여 학습시키고, 해저산 중심 위치 산출 정확도를 분석함으로써 최적의 특징점 추출기를 모델링하는 연구를 수행하였다. 본 논문에서 제안하는 알고리즘을 기반으로 수중 운동체의 주행 경로상의 해저지형을 사전에 분석함으로써 자율 주행에 기여할 수 있다.

Abstract

This paper proposed a deep learning training algorithm utilizing CNN(convolutional neural network) techniques to estimate the central position of seamount from seafloor topography images. Approximately 150 seafloor topography images were generated from bathymetric data near the Korean Peninsula for training, and the accuracy of sea mount center estimation was analyzed to model an optimal feature extractor. Based on the proposed algorithm, pre-analysis of seafloor topography along the trajectory of underwater vehicles can contribute to autonomous navigation.
