The invention provides a ship navigation early warning method and system based on an electronic fence, and relates to the field of ship navigation early warning, and the method comprises the steps: inputting an image to a preset image segmentation model, and obtaining a target ship, an obstacle and a current water level height; inputting the current water level height to a preset water area model to obtain a dynamic electronic fence; determining the current speed according to the position information of the target ship, and determining the current course change speed according to the motion track of the target ship; and inputting the current speed, the current course change speed, the first distance and the second distance to a preset ship navigation early warning model to obtain a risk assessment result, and determining a course early warning strategy of the target ship according to the risk assessment result. According to the method, the current speed, the course and the distance between the barrier and the electronic fence are comprehensively considered, the early warning accuracy is improved, the dynamic or static electronic fence mode is intelligently selected according to the change amplitude of the water level height, the early warning real-time performance is considered, and the calculated amount can be reduced as much as possible.
本发明提供了一种基于电子围栏的船舶航行预警方法及系统,涉及船舶航行预警领域,该方法包括:输入图像至预设图像分割模型,得到目标船舶、障碍物及当前水位高度;输入当前水位高度至预设水域模型,得到动态电子围栏;根据目标船舶的位置信息确定当前速度,根据目标船舶的运动轨迹确定当前航向变化速度;输入当前速度、当前航向变化速度、第一距离以及第二距离至预设船舶航行预警模型,得到风险评估结果,根据风险评估结果,确定目标船舶的航向预警策略。本发明综合考虑当前速度、航向、与障碍物和电子围栏的距离,提高预警准确性,根据水位高度变化幅度,智能地选择动态或静态电子围栏模式,不仅考虑到预警实时性,还能够尽可能降低计算量。
