The invention discloses an overwater ship traffic flow complexity calculation method and device, equipment and a medium. The method comprises the following steps: acquiring ship AIS data of a target water area; determining a ship cluster in the target water area according to the ship AIS data by using an improved DBSCAN algorithm; performing ship state feature clustering on the ship clustering cluster to obtain state feature probability distribution of the ship clustering cluster; and determining the ship traffic flow complexity of the target water area based on information entropy according to the state feature probability distribution. According to the invention, the improved DBSCAN algorithm is innovatively obtained based on the ship domain model, so that the algorithm is more fit with navigation practice; according to the state feature probability, the uncertainty of the water traffic flow state is described through the information entropy, the method for measuring the complexity of the water ship traffic flow in the field of water traffic engineering is expanded, and the method has important theoretical and practical significance for boosting maritime affair safety supervision informatization.

    本申请公开了一种水上船舶交通流复杂度计算方法、装置、设备和介质,该方法包括:获取目标水域的船舶AIS数据;利用改进的DBSCAN算法根据所述船舶AIS数据确定所述目标水域中的船舶聚类簇;对所述船舶聚类簇进行船舶状态特征聚类,得到所述船舶聚类簇的状态特征概率分布;根据所述状态特征概率分布,基于信息熵确定所述目标水域的船舶交通流复杂度。本发明基于船舶领域模型创新性地得到了改进的DBSCAN算法,使算法与航海实践更为贴合;根据状态特征概率,通过信息熵来描述水上交通流状态的不确定性,拓展了水上交通工程领域水上船舶交通流复杂性度量的方法,对助推海事安全监管信息化具有重要的理论和现实意义。
