本发明公开了一种解决船舶MMSI码串号轨迹的处理方法,属于船舶轨迹优化领域,包括如下步骤:S100.获取船舶行驶的轨迹点,预设轨迹点之间的时间间隔阈值和距离阈值;预判下一轨迹点的位置,以该预判轨迹点的位置为中心形成预测圆,得到轨迹点位于至少一个预测圆内的结果;若存在轨迹点同时位于多个预测圆内,则选取与轨迹点之间时间间隔最小的预测圆;判断轨迹点与前置轨迹点之间是否小于时间间隔阈值;若满足,则将轨迹点加入轨迹链中;S200.对得到的所有轨迹链进行筛选;S300.处理轨迹点中的轨迹折返点;S400.进行抽稀处理;S500.拟合得到轨迹曲线。本发明公开的处理方法,通过将获取的轨迹点进行分组、筛选,解决船舶存在“一码多船”造成轨迹错乱的情况。

    The invention discloses a processing method for solving a ship MMSI code serial number track, and belongs to the field of ship track optimization, and the method comprises the following steps: S100, obtaining ship driving track points, and presetting a time interval threshold value and a distance threshold value between the track points; pre-judging the position of a next track point, forming a prediction circle by taking the position of the pre-judged track point as a center, and obtaining a result that the track point is located in at least one prediction circle; if the track points are located in the plurality of prediction circles at the same time, selecting the prediction circle with the minimum time interval with the track points; judging whether the time interval between the track point and the front track point is smaller than a time interval threshold value or not; if yes, adding the track points into the track chain; s200, all the obtained track chains are screened; s300, track turning points in the track points are processed; s400, carrying out a thinning treatment; and S500, fitting to obtain a trajectory curve. According to the processing method disclosed by the invention, the obtained track points are grouped and screened, so that the situation of track disorder caused by'one code and multiple ships' of the ships is solved.
