摘　　要：航迹去纠缠处理是基于自动识别系统(Automatic Identification System,AIS)数据进行船舶运动行为深入分析的基础。传统航迹去纠缠处理方法存在虚警率和漏警率均较高的问题,这会造成重要船舶运动特征信息缺失以及纠缠去除不彻底等,进而影响数据的可用性。基于此,通过分析船舶AIS原始定位数据特点以及船舶运动属性特征,提出基于运动属性约束的船舶AIS航迹去纠缠方法(A Method for Removing Entanglement of AIS Trajectory Based on the Constraints of Motion Attributes,CoMA),以瞬时航行速度和时间间隔约束船舶空间位置合理范围,以瞬时航向约束船舶转向的合理区间,双重约束下对航迹纠缠点进行去除。通过实例验证与对比可得,相较于传统航迹去纠缠方法,该方法能够在纠缠点彻底、精准、高效去除的前提下,最大程度地保留船舶运动行为特征,可为后续船舶航迹深入分析提供准确的数据输入。Removing entanglement of Automatic Identification System(AIS)trajectory is the basis of the in-depth analysis of ship motion behavior.The traditional processing methods of removing entanglement of trajectory have the problem of high false alarm rate and false negative rate,which will lead to the loss of important ship motion feature information and incomplete entanglement removal,thus affecting the availability of data.Therefore,the method for removing entanglement of ship AIS trajectory based on the Constraints of Motion Attributes(CoMA)is proposed,by analyzing the characteristics of ship AIS original positioning data and ship motion attributes.The CoMA removes the entanglement points of the ship trajectory by simultaneously restricting the reasonable range of the ship’s spatial position and the turning.Example verification and comparison with other methods show that the CoMA can retain the characteristics of ship motion behavior to the greatest extent under the premise of thorough,accurate and efficient removal of entanglement points,and can provide accurate data input for the subsequent in-depth analysis of ship trajectory.
