Experimentation for development of underwater acoustic video camera: In experiment dock

Ocean resources exploration and underwater works using Remotely Operated Vehicle and Autonomous Underwater Vehicle increase interest, and a techniques of underwater image with acoustic has become a significant concern. Therefore, a development of new underwater acoustic device adapted to ocean resources exploration and underwater works. In this study, we experiment with the use of acoustic video camera for development of a new acoustic video camera and software to meet ocean resources exploration and underwater works needs. The experiment was performed by means of an acoustic video camera, underwater teleoperated excavator, underwater crawler, and simulated chimney. High spatial imaging and software were developed for this experiment and they were used to generate 3D views, to display an operation views and measurement distance of targets. Our results will be necessary for the ocean resources exploration and underwater works.
