The invention relates to a ship turning radius calculation method and system and a computer medium, and the method comprises the steps: checking whether ship power propulsion and a rudder angle are stable, obtaining the current power propulsion and rudder angle values, and plotting the subsequent positions P1, P2 and Pn of a ship on a nautical chart according to the current position P0 of the ship and the time interval T of each time; sequentially obtaining position vectors P01, P12 and P (n-1) n according to two adjacent positions; detecting and calculating an ocean current motion vector, and subtracting the ocean current motion vector from the ship position vector to obtain an actual motion vector of the ship; drawing a vertical center line of the actual motion vectors S01 and S12 of two adjacent ships, extending the vertical center line to enable the vertical center line to intersect, and geometrically calculating the linear distance between the intersection point S and the intersection point O to obtain R1; the turning radius under the current power and rudder angle condition is obtained through mean value calculation; a computing system and a computer medium are also included. The method, the system and the medium have the advantages of being rapid in calculation and high in accuracy.

    本发明涉及一种船舶转弯半径的计算方法、计算系统及计算机介质,该方法包括:检查船舶动力推进和舵角是否稳定,获得当前动力推进和舵角数值,并根据本船当前位置P0,每次均间隔时间T,在海图上标绘出本船后续所在位置P1、P2、Pn;根据相邻两个位置依次得出位置矢量P01、P12、P(n‑1)n;检测并计算洋流运动矢量,并利用本船位置矢量减去洋流运动矢量,得出船舶实际的运动矢量;画出相邻两个船舶实际运动矢量S01和S12的垂直中线,并通过延长垂直中线使其相交,通过几何计算出交点S与交点O的直线距离,得出R1;通过均值计算获取当前动力和舵角情况下的转弯半径;还包括计算系统及计算机介质。本发明的方法、系统及介质具有计算快速且精准性高的优点。
