Outline of Final Research Achievements

In the research feild about deep sea ecosyste that it is difficult to gether samples, image taken by an underwater vehicle are very important and valuable. Many scientis try to figure out the composition and architecutre of marine organism. On the other hand, the images can not show and express the 3D size, shape and geometric information; such as 2-point distance, area and volume; of marine organism. So in this research, the underwater camera model, which is monted on an underwater vehicle, was designed. It can compensates an complex optical refraction characteristic in each medium. The 3D image with high resolution can be created because it was applied into a stereo vision system. Also, it can calculate and 3D geometric information of shooting objects on the 3D image. The vison system was used in some sea trials and its utility and practicality were shown as results of the sea trials.
