Method and system for autonomously planning and generating path of unmanned ship in complex unknown water area

The invention provides an autonomous path planning generation method and system for an unmanned ship in a complex unknown water area, and the method comprises the steps: respectively obtaining a first position of a final destination when the unmanned ship travels for a single time, and a second position of the unmanned ship in the water area at present; obtaining a target image in a preset range around the unmanned ship in the water area; planning a plurality of obstacle avoidance driving paths based on the target image; based on the first position and the second position, selecting a target obstacle avoidance driving path from the obstacle avoidance driving paths; and based on the target obstacle avoidance driving path, controlling the unmanned ship to perform corresponding temporary obstacle avoidance driving. According to the autonomous path planning and generating method for the unmanned ship in the complex unknown water area, the unmanned ship is controlled to travel in the complex unknown water area, th
