Abstract

The invention discloses an intelligent naval ship automatic cruise simulation method. The intelligent naval ship automatic cruise simulation method is characterized by regarding a ship as a mass pointand placing the ship into a virtual force field, setting a cruise target position to be a lowest potential energy point in the virtual force field, setting an obstacle position to be a highest potential energy point, calculating a gradient of a gravitational potential function of the ship position, regarding the gradient as an input signal of a ship control system, calculating an obstacle repulsive force potential energy field gradient to obtain an obstacle repulsive force applied to the ship, utilizing a resultant force of gravitation and the repulsive force to calculate acceleration of theship in the virtual force field, and mapping the acceleration into a virtual environment as an input signal of the ship control system, thereby realizing cruise of the ship in the virtual environment.The intelligent naval ship automatic cruise simulation method realizes automatic obstacle avoidance of the ship by adopting an artificial potential energy field method, enables the ship to sail to the target position quickly and precisely while avoiding the obstacle, makes the entire simulation process in line with th physical law without specifying a route in advance, thereby realizing the single-ship or multi-ship automatic cruise in the virtual environment.

Description

technical field [0001] The invention relates to a simulation method for automatic cruising of an intelligent ship, which belongs to the technical field of data processing. Background technique [0002] At present, the automatic cruise of ships in the Unigine environment does not use a control system, and is only simulated by a simple course offset or a fixed trajectory that does not follow the dynamics. There are problems such as poor control accuracy and trajectory distortion. When multiple ships are cruising, using the existing course offset method will frequently cause ship collision problems, and obstacles cannot be avoided automatically. However, the use of the existing fixed trajectory navigation method lacks a theoretical basis for dynamics, and the navigation trajectory does not conform to the laws of physics, and it is necessary to specify a trajectory for each ship, which is complicated to use and the simulation effect is distorted. In short, the existing ship aut...
