The invention discloses a method for detecting and eliminating an abnormal value of ship route data and a navigation monitoring system. The method comprises the following steps of: firstly, acquiring ship route trajectory data; performing abnormal value detection on the trajectory data by using a predefined algorithm, and identifying an abnormal data interval where an abnormal value is located; interpolation is carried out on the abnormal data interval where the identified abnormal value is located, the abnormal data are deleted, and replacement data are obtained; and finally, outputting the ship route trajectory data after the abnormal value is eliminated, and drawing a route trajectory on a map. Therefore, by adopting the method provided by the invention, the abnormal value in the ship route trajectory data can be quickly and accurately eliminated, and the accurate route trajectory can be drawn on the map; the system can be conveniently integrated into a navigation monitoring system so as to improve the utilization efficiency of navigation data; the simple, rapid and accurate ship navigation data analysis method is realized.
本发明公开了一种航线数据异常值检测与消除的方法及航行监视系统,其中方法先获取船舶航线轨迹数据;再利用预定义算法,对轨迹数据进行异常值检测,并识别出异常值所在的异常数据区间;接着对识别出异常值所在的异常数据区间进行插值,删除异常数据,得到替换数据;最后输出消除异常值后的船舶航线轨迹数据,并在地图上画出航线轨迹。可见,采用本发明的方法,可以快速、准确地消除船舶航线轨迹数据中的异常值,并在地图上画出准确的航线轨迹;还可方便地集成到航行监控系统中,以提高航行数据的利用效率;实现了一种简单、快速、准确的船舶航行数据分析方法。
