说明：  分析了现有船舶自动避碰系统的不足,提出了基于人工势场法的船舶自动避碰系统. 根据 船舶的操纵特性,建立了引力场和斥力场函数,实现船舶自动避碰航行的合力和方向. 在电子海图 所建立的仿真环境中,验证了人工势场法可用于船舶自动避碰系统中.(Analysis of existing ships lack of automatic collision avoidance system is proposed based on artificial potential field method automatic collision avoidance system for ships. According to the ship maneuvering characteristics, the establishment of a gravitational field and the repulsive force field function, automatic collision avoidance to achieve ships sailing together, and direction. in the electronic chart of the simulation environment created to verify the artificial potential field method can be used to ship automatic collision avoidance system.)
