The invention provides a ship collision early warning method and device, and the method comprises the steps: calculating the relative motion parameters of a current ship and a target ship through a preset relative motion parameter model in combination with the obtained current ship information and target ship information; based on the target ship information and the current ship information, constructing a ship safety field of the current ship between the current ship and the target ship during navigation; based on the ship safety field and the relative motion parameters, whether collision danger exists between the target ship and the current ship or not is judged; if the collision risk exists, quantifying the collision risk by using a fuzzy theory to obtain a ship collision risk quantized value; and based on the ship collision risk quantized value and in combination with the invasion degree of the target ship to the ship safety field, dividing ship collision risk grades. Therefore, the problems that an existing collision risk quantification and early warning method is insufficient in consideration of ship scales and behavior elements, simple in early warning grade division and high in subjectivity are solved.
本申请提供的一种船舶的碰撞预警方法及装置,方法包括:利用预设的相对运动参数模型,结合所获取的当前船舶信息和目标船舶信息,计算当前船舶与目标船舶的相对运动参数;基于目标船舶信息和当前船舶信息,构建当前船舶与所目标船舶在航行间,当前船舶的船舶安全领域;基于船舶安全领域和相对运动参数,判断目标船舶与当前船舶之间是否存在碰撞危险;若存在碰撞危险,则利用模糊理论对碰撞危险量化,得到船舶碰撞风险量化值;基于船舶碰撞风险量化值,并结合目标船舶对于船舶安全领域的侵入程度,划分船舶碰撞风险等级。从而解决现有碰撞风险量化及预警方法在船舶尺度和行为要素考虑不足、预警等级划分简单和主观性强的问题。
