Abstract :
This paper presents a new method to fulfill the contour match of seabed topography through image match algorithms. Firstly, the generation of topographic contour image is studied. Then, the theory of image matching is introduced. Based on above, a complete matching process is given out. Finally, a positioning experiment is implemented by means of contour image match. Positioning accuracy is better than 5 meters.
