Abstract:  To solve the local path planning problem of unmanned surface vehicle (USV), this paper designed a path planning method based on marine radar image processing. An image’s edge preserving smoothing algorithm and an adaptive threshold election algorithm were used for marine radar image processing, then a mathematic model for the environment was founded, and the path was searched by a search of shortcut Dijkstra algorithm. Good results were received from experimental data in the sea and lake,with an optimal path identified in a short time that could satisfy the experimental need.

Key words: unmanned surface vehicle (USV), marine radar, image processing, Dijkstra algorithm, local path planning
