The present invention discloses a vessel collision avoiding system and method based on Artificial Potential Field algorithm, the method comprises the following steps: (S) obtaining a vessel information, at least one obstacle information and a target information; (S) establishing an Artificial Potential Field (APF) by the vessel information, the at least one obstacle information and the target information, wherein the Artificial Potential Field comprises an attractive field of the target and a repulsive field of the obstacle; (S) combining the attractive field and the repulsive field to obtain a first resultant force; (S) Adding an external force to the Artificial Potential Field based on the vessel information or the obstacle information; (S) combining the first resultant force and the external force to obtain a second resultant force; and (S) the vessel sails in the direction of the second resultant force to avoid the obstacle.

The present invention relates to a vessel navigation system and navigation method thereof, the method includes: (a) driving a vessel to sail along a sailing path including at least two nodes, the at least two nodes include a first node and a second node connected by a first line segment; (b) generating a first tracking point on the first line segment when a distance between the vessel and the first node being less than a first length, and driving the vessel to sail according to the first tracking point; (c) generating a second tracking point on the first line segment when a distance between the vessel and the first tracking point being less than the first length, and driving the vessel to sail according to the second tracking point; and then completing the navigation of the sailing path by repeating the step (b) and step (c) until the vessel passes through each node.
