The invention relates to the field of maritime ship navigation, in particular to a method for constructing a ship tracking decision probability model and a program product. The method mainly comprises the following steps: selecting a research area and establishing a static coordinate system; converting longitude and latitude coordinates of the ship and determining a dynamic tracking space; screening ship information in the dynamic tracking space; important parameters in the ship tracking process are calculated; analyzing the motion trend of the ship; calculating the safe following distance of the ship; calculating the safe transverse spacing of the ship; drawing a ship relative potential energy field; calculating a ship speed-based tracking intention and a longitudinal tracking allowable space; calculating left and right board passing permissible space; and establishing a ship tracking decision probability model. Compared with the prior art, the method has the advantages that a reference scheme can be provided for the tracking behaviors of various types of ships when the ships sail on the sea, the optimal tracking opportunity of the ships can be analyzed, and then the tracking risk of the ships is minimized.

    本发明涉及海事船舶航行领域,尤其是涉及一种构建船舶追越决策概率模型的方法及程序产品。其中,该方法主要包括:选定研究区域并建立静态坐标系;转换船舶经纬度坐标并确定动态追越空间;筛选动态追越空间内的船舶信息;计算船舶追越过程中的重要参数;分析船舶的运动趋势;计算船舶安全跟驰间距;计算船舶安全横向间距;绘制船舶相对势能场;计算基于船速的追越意图和纵向追越允许空间;计算左右舷追越允许空间;建立船舶追越决策概率模型。与现有技术相比,本发明不仅能为多种类型的船舶在海上航行时的追越行为提供参考方案,还可以分析船舶最佳追越时机,进而最小化船舶的追越风险等优点。
