| Outline of Final Research Achievements |
We developed a new measurement system for 3D visualization of underwater by using high-resolution acoustic video camera. The method can visualize the underwater with 1 cm resolution without the effect of transparency of water. In addition, we developed a new measurement system to visualize the space of under the water bottom. We confirmed a natural plant root with diameter of 0.025 - 0.030 m in the reconstructed three-dimensional acoustic image. The plant root was at a depth of about 0.54 m. The measurement systems for aquatic plant will be useful for the non-destructive assessment of the status of the space under the water and water bottom.
