全天球ステレオカメラを用いた養殖魚3次元計測システムの開発

In fish aquaculture, it is important to monitor the growth of fish in the fishpond for aquaculture control. In this paper, we develop a system for 3D measurement of aquaculture fish using a 3D reconstruction technique based on spherical stereo camera. In the experiment, 3D measurements of fish bodies were conducted in both a simulated environment using CG images generated by a game engine, and a real environment using images captured in a fishpond. The experimental results showed that the proposed method enables accurate measurement of the size distribution and average size of fish in the fishpond. The mean values of fork length, body height, and body weight could be measured within ±5% error for both simulation and real environments. These results show that the proposed method was suggested to be effective as a growth management system for aquaculture fish.
