In this paper, we propose an automatic shark detection method in deep sea by light section method, in order to realize shark observation with much less energy. This method detects sharks on the basis of cross-sectional shape obtained by light section method. To analyze the performance of the proposed method, experiments at aquariums was conducted. It was observed that detection accuracy became high...
Autonomous underwater vehicles (AUVs) have advantage that they do not require tether cables or human control. AUVs have recently been used for seafloor observation. However, AUVs have limitation of their batteries. AUVs must be recovered before they have run out of batteries. In order to charge batteries of AUVs, underwater charging systems have attracted a lot of attention. We have developed the...
