The authors investigated a method to extract navigational information, for example ship's position and velocity, using a visual images taken from a 35mm camera. In this paper, an applications of image transformation is proposed. At first, order to solve the problem, which it is that the photograph image include the error like an optical distortion and aberration, we led to the equation-the so-called Error Correcting Equation Model (ECEM). Next, the ship's position, length and other navigational information were able to obtain for using ECEM, and those results were fairly good agreement with the actual position, waterline length, and so on. Secondly, Kalman Filter was applied to estimate with the navigational information. As the results, it is shown that the most probable navigational information is estimated with a high accuracy by using Kalman Filter on the proposed applications of image transformation.
