Authors have been developing the underwater robot which can be used for environmental protection work in the sea near Okinawa. It is difficult to get the position of underwater robot, because GPS does not work in water. Our research field (the Okinawan sea) is high degree of transparency, so we try to develop the inexpensive measurement for underwater robot using a monocular camera. In this paper, we illustrate the measurement method and examination of the position accuracy.
