Abstract: In the context of the opening of the Arctic shipping channel, in view of the particularity of ship navigation path selection in the ice navigation environment, in order to realize the intelligent navigation of ships, the influence mechanism of the main dimensions, speed, heading and other factors on navigation safety on both sides of the collision avoidance is first analyzed, and the analytical expression method of danger perimeter and warning perimeter is proposed, and multiple collision avoidance perimeters for safe navigation at sea are constructed. Then, the navigation connection diagram of the ship is constructed based on the method of probability diagram. Subsequently, by considering the influence of navigation energy consumption and path length, the particle swarm optimization (PSO) algorithm is optimized, the fitness function is improved, and a multi-objective planning model for path selection is established. By considering the ship model of wind and flow separation, the planned route is smoothed and optimized. Finally, based on the remote sensing sea ice images, a raster model of the ice channel environment with sea ice coverage of 30% and 50% is established, and the algorithm is applied to the raster model to verify the algorithm
