The invention discloses a marine dynamic zebra crossing prediction method based on a ship traffic flow, and the method comprises the steps: obtaining the historical features of the ship traffic flow in real time, and generating a marine dynamic zebra crossing delimited threshold value according to the historical features of the ship traffic flow; according to a ship navigation environment, ship traffic flow data is disassembled into stationary part data and fluctuation part data, a traffic flow data matrix decomposition mathematical model is established according to the stationary part data and the fluctuation part data, and a ship traffic flow prediction result is calculated according to the traffic flow data matrix decomposition mathematical model. According to comparison between a ship traffic flow prediction result and the marine dynamic zebra crossing delimiting threshold value, whether the marine dynamic zebra crossing is delimited or not is judged, and the problems of unreliability and low effectiveness caused by a marine zebra crossing static setting method are solved; the provided method for setting the marine zebra crossing based on the real-time ship traffic flow prediction method can efficiently solve the problems of time precision and space precision faced by zebra crossing setting.

    本发明公开了一种基于船舶交通流的海上动态斑马线预测方法,通过实时获取船舶交通流历史特征,根据所述船舶交通流历史特征生成所述海上动态斑马线划定阈值,根据船舶通航环境将船舶交通流数据拆解为平稳部分数据和波动部分数据,根据所述平稳部分数据和波动部分数据建立交通流数据矩阵分解数学模型,并根据所述交通流数据矩阵分解数学模型计算得出船舶交通流预测结果,根据船舶交通流预测结果与所述海上动态斑马线划定阈值对比,判定是否划定海上动态斑马线,克服了海上斑马线静态设置方法带来的不可靠和实效性低的问题,提出的基于实时船舶交通流预测方法设置海上斑马线能高效的解决斑马线设置面临的时间精度和空间精度问题。
