The invention provides a marine traffic network construction method and device, electronic equipment and a readable storage medium, and the method comprises the steps: carrying out the preprocessing of AIS data, including the filtering of abnormal data in a specified research range, the screening of ship AIS data, the segment processing of a journey, and the calculation of a complementation SOG value; analyzing the track set, extracting static and dynamic feature points, identifying a main category cluster through a clustering algorithm, and calculating a convex hull to determine a region boundary; and projecting the feature points into a grid for filtering, retaining important feature points, constructing a flow direction, and finally forming a complete maritime traffic network. According to the invention, through AIS data preprocessing, feature point extraction, clustering analysis, region division and flow direction construction, an accurate maritime traffic network is generated, and decision support is provided for maritime affair management.
本发明提供一种海上交通网络构建方法、装置、电子设备及可读存储介质,所述方法包括对AIS数据进行预处理,包括指定研究范围过滤异常数据、筛选船舶AIS数据、行程分段处理和计算补全SOG值;分析轨迹集合提取静态和动态特征点,并通过聚类算法识别主要类别簇,计算凸包确定区域边界;将特征点投影到网格中进行过滤,保留重要特征点,构建流向,并最终形成完整的海上交通网络。通过本发明,通过预处理AIS数据、提取特征点、聚类分析、区域划分和流向构建,生成精确的海上交通网络,为海事管理提供决策支持。
