The invention discloses a ship high-density area supervision method and system in a maritime mixed traffic scene. The method comprises the following steps: S1, acquiring ship AIS data in a maritime mixed traffic scene; s2, latitude and longitude coordinates of the ship AIS data are extracted, and a ship core distance and reachable distance ordered sequence is obtained through calculation; calculating to obtain ship areas with different density degrees through a gradient threshold method; determining a ship high-density area by calculating the average core density of each ship area; and S3, the ships with the multiple driving modes having the collision risk in the ship high-density area are dispatched. According to the method, the areas with different ship densities are calculated by calculating the distance relation between the ship points and the gradient threshold value of the ordered sequence of the distances that the ship points can reach, then the area with the highest ship density is determined, different instruction distribution modes are adopted for the ships with people on the ship and the ships without people on the ship, and the ship density is determined. And a shore-based supervisor is assisted to dispatch and supervise the ship with the collision risk in the mixed traffic scene.

    本发明公开了一种海上混合交通场景下船舶高密度区域监管方法及系统。方法包括:S1、获取海上混合交通场景中的船舶AIS数据;S2、提取船舶AIS数据的经纬度坐标,计算获得船舶核心距离和可达距离有序序列;通过坡度阈方法计算得到不同密集程度的船舶区域;通过计算各个船舶区域的平均核心密度来确定船舶高密度区域;S3、对船舶高密度区域内存在碰撞风险的多种驾驶模式船舶进行调度。本发明通过计算船舶点之间的距离关系,以及船舶点可达距离有序序列的坡度阈值来计算获得不同船舶密度的区域,进而确定船舶密度最高的区域,针对有人在船和无人在船船舶,采用了不同的指令派发方式,辅助岸基监管人员对混合交通场景中的存在碰撞风险的船舶进行调度监管。
