Ship trajectory optimization method based on artificial intelligence and marine environment

The invention relates to the technical field of ship control, and particularly discloses a ship trajectory optimization method based on artificial intelligence and a marine environment. According to the method, a basic ship trajectory is planned and generated by acquiring a departure point and a destination point of ship navigation; dividing the basic ship trajectory to obtain a plurality of stages of ship trajectories; performing stage internal comparison on the multi-stage navigation data, and selecting a plurality of stage selection tracks; real-time positioning and environment monitoring are carried out, and ship positioning data and marine environment data are obtained; and based on an artificial intelligence technology, optimizing the stage selection trajectory according to the ship positioning data and the marine environment data, generating a stage optimization trajectory, and performing ship navigation control. After a basic ship trajectory is obtained through navigation planning, stage division is p
