National Maritime Research Institute(at that time, Ship Research Institute) carried out cooperative research on the examination study of a launching Free Fall Life Boat(abbreviated expression 'FFLB' is used in this paper) into waves with the U.S. Clemson University in 1998 fiscal year. A used water tank was 50m long,8m wide and 4.5m deep with the wave generator, which is belonged to the Ship Dynamics Division, and free fall tests were carried out in the wave of the height 0.3m by using the wave generator with changing position relations with the wave at the entry into the water. National Maritime Research Institute took charge of movement measurement by video cameras. Pictures of the pattern in the free fall were took from 2 direction by using two video cameras, and the pictures were recorded. It is so difficult to determine the position, posture and magnification of video cameras precisely, that the method for estimation of those values were developed in this research. In this paper the method was explained in detail, and the effectiveness of the method are pointed out by an example and the estimation of 3-dimensional positions of FFLB from 2-dimensional video image.
