陸上養殖における水中自動体測のための複数ステレオカメラを用いた拡張視野における3次元計測

In recent years, along with increase of seafood consumption, land-based aquaculture draws attention for its low environmental load and less location restrictions. In fish aquaculture plants, measurement of fish size is important for growth management. In current system for land-based aquaculture, however, the measurement for which the fishes are landed is heavy load for both the fishes and plant workers. Thus, underwater body measurement is highly demanded. However, the underwater measurement is quite difficult task because rearing water of fish tanks becomes turbid easily. In particular, to measure fishes in the turbid water, a method to capture fishes from near distance with wide field of view is necessary. In this paper, a system to measure fish bodies in the turbid water using multiple stereo cameras is proposed. In an experiment in an actual land-based aquaculture plant, the performance of the proposed system is validated.
