| Research Abstract |
In this study, we propose an underwater sensing method via image information with consideration of propagation characteristics of light. Sensing in aquatic environments meets the difficulty that, when a camera is set in air behind a watertight glass plate, image distortion occurs by refraction of light at the boundary surface between air and water. This study proposes a sensing method to execute 3D measurement of objects in water by taking refraction, attenuation, and interruption of light into account.
