Outline of Final Research Achievements

We have conducted research to establish mapping technology by introducing photogrammetry technology (SfM) and small underwater robot (sROV) into the underwater environment where detailed maps have not been created. After establishing the imaging technology and operation technology, we studied accuracy of the survey. We, then, surveyed and made high definition model of underwater plants, gravel, and underwater topography. Changes in underwater topography were also investigated.

Academic Significance and Societal Importance of the Research Achievements

本研究によってこれまで難しかった浅い水域の地形や植生，礫などを測定することが可能になった。また，こうした領域は今後の気候変動で環境が大きく変化することが見積もられ，本研究の結果は環境モニタリングや炭素貯留量を見積もる際にも重要な知見となると考える。
