Recently the research and the development on sailing support system using video information have been advancing owing to the development of image processing technology. As for vessels, the sailing monitoring systems to watch all directions of the vessels by using omni directional image sensors have been proposed. But there are some problems on this system as follows: (1) It is difficult to confirm the distance between the vessels and the bridge when they leave or reach the shore. (2) It is too slow to do the real time processing. This is why we developed the system which can judge a positional relationship between the vessels and the bridges visually by proposing on a real time a pseudo image from the sky. We are making use of USB camera equipped with fish-eye lenses to get images. In this paper, we experimented by attaching the camera at the medium seized vessel, which have a total length of 40 meters. As a result, we found that it is possible to display a positional relationship between our ship and bridges when our ship leaves or reaches the shore, and also to display corrected images on a real time at the frame rate 10fps.
