AUV Tri-TON is a hovering type autonomous underwater vehicle developed by the University of Tokyo, launched in 2011. The vehicle was constructed as a testbed under the governmental project to develop instruments to estimate ore reserves in underwater hydrothermal deposits. The vehicle's mission is to obtain dense, large-area 3D image of hydrothermal vent(More)
Although autonomous underwater vehicles(AUVs) are suitable for seafloor imaging, it is currently difficult for them to evaluate the results on-site. Therefore the obtained image map often has unscanned areas caused by occlusions, disturbances, and so on. In order to improve the coverage of the map, operators have to plan a new path and then deploy the AUV(More)
Although AUVs can observe seafloor without tether cables nor human control, it is impossible for operators to confirm in real time that there are no unscanned areas caused by occlusions, positioning errors, and so on. If unobserved areas are found by post processing, another deployment of the AUV is necessary to cover them. Therefore, we have proposed a(More)
The Single-Slope (SS) ADC is a simplified architecture; therefore, it is widely used in a variety of image sensors. But, to achieve a high-speed operation without using a high-speed clock is almost impossible. In order to achieve a high speed operation, using a very high-speed clock will increase the power consumption of the ADC significantly. In this(More)
