The invention relates to a restricted water area ship collision avoidance decision support method and device, and belongs to the technical field of ship collision avoidance. The restricted water area ship collision avoidance decision support method comprises the following steps: under the condition of determining that a target ship has a collision risk, determining the collision risk of the target ship; determining a collision avoidance space of the target ship based on limited water area characteristics, ship maneuverability and a collision avoidance principle; performing initial population generation in the collision avoidance space based on a difference innovation search algorithm, and performing trajectory prediction on an initial population position to obtain fitness corresponding to the initial population position; updating the initial population position for multiple times based on a sparrow search algorithm; and updating the weight factor based on the time sequence, adjusting the position of the discoverer, and taking the trajectory prediction result of the updated initial population position as the collision avoidance path of the target ship. The collision avoidance decision support of the ship in the limited water area is realized, the ship collision avoidance realization scene is expanded, and the ship navigation safety is improved.
本发明涉及一种受限水域船舶避碰决策支持方法及装置,属于船舶避碰技术领域,其中,该受限水域船舶避碰决策支持方法包括:在确定目标船舶存在碰撞风险的情况下,基于受限水域特性、船舶操纵性及避碰原则确定所述目标船舶的避碰空间;基于差异创新搜索算法在所述避碰空间中进行初始种群生成,并对初始种群位置进行轨迹预测,得到初始种群位置对应的适应度;基于麻雀搜索算法多次更新所述初始种群位置;基于时序更新权重因子,调节发现者位置,将更新后的初始种群位置的轨迹预测结果作为所述目标船舶的避碰路径。本发明实现了船舶在受限水域下的避碰决策支持,拓展了船舶避碰实现场景,提高了船舶航行的安全性。
