Remotely operated vehicle(ROV) and autonomous underwater vehicle(AUV) have been used for underwater surveys, underwater exploration, resource harvesting, offshore plant maintenance and repair, and underwater construction. It is hard for people to work in the deep sea. Therefore, we need a vision control system of underwater submersible that can replace human eyes. However, many people have difficulty in developing a deep-sea image control system due to the deep sea special environment such as high pressure, brine, waterproofing and communication. In this paper, we will develop an Ethernet based remote image control system that can control the image mounted on ROV.

The Korean government is considering the implementation of a project to develop a deep-sea human-operated vehicle (HOV) to improve the level of deep-sea research. Information on the scientific benefits from the project is urgently needed in order to come to a decision about whether to implement the project. This paper measures the conservation value of developing nine attributes associated with HOV by using the choice experiment (CE). A survey of about 356 experts was undertaken and 132 experts completely responded to the survey. To deal with the CE data from the survey, we employed a multinomial logit model. All the coefficient estimates are statistically significant and consistent with prior expectations. Therefore, we can judge that the respondents' works required in the CE survey were within their cognitive abilities and they reported responsible and significant values. Each marginal willingness to pay for each attribute associated with the HOV is statistically significant and provides good information on the scientific values with regard to developing the HOV. The results can be utilized in evaluating and planning several alternatives related to developing the HOV.
