Visualizing the drift of fishing gear using drone

The authors have been working on support of coastal fishing utilizing ICT since 2004. We have realized two visualizations for the sustainable fishery until now. One is visualization of resources for capture fishing using digital diary and the other is visualization of environment for culture fishing using small buoys. In this paper, we propose the visualization of technology for octopus drift fishing using drone as the third visualization. The experimental results showed that we were able to calculate the drift speed of fishing gear by image processing of video of fishing ground taken by drone.
