Abstract: In the process of visual navigation, image processing unit processes the image collected by CCD in order to pick up the navigation parameters. Traditional method of collecting navigation parameters is slow in collecting speed and unclear in the collected route. This paper presents an improved algorithm of collecting navigation parameters with the advantages of small calculating works and optimizing easily, which is used in DSP. With the help of this algorithm, this paper realizes the fast collecting of the navigation parameters and the collected route is clear and accurate.
