Sea urchin survey by small ROV : – Study of the Urchin barren –

摘要

Currently, on the coast of Japan, a sea urchin barren occurred, causing a great deal of damage. Therefore, we constructed a system to conduct sea urchin quantity survey using small ROV. We conducted a survey in Shizugawa bay using the present system. As a result, we found a large amount of large sea urchins near the water depth of 20 m. We also developed a sea urchin survey system using machine learning and conducted experiments.
