The invention discloses a ship situation danger detection method in the inland ship domain. The method comprises the following steps: establishing an inland ship domain model; obtaining an external safety distance boundary formula through the inland ship domain model; establishing a coordinate system relative to a ship body, and obtaining a target ship coordinate TS; the target ship speed is obtained through the target ship coordinate TS, and the relative speed of the ship and the target ship is obtained through the target ship speed; establishing a collision danger detection line expression through the target ship coordinate TS, and determining a collision intersection point coordinate through a collision prediction expression and an external safety distance boundary equation; the meeting time of the collision danger detection line of the target ship and the ship domain safety distance boundary intersection point is obtained through the collision intersection point coordinates and the relative speed; according to the position relation between the collision danger detection line and the safe distance boundary and the encounter time, the inland ship situation danger level is divided, danger collision detection can be carried out in real time, safety is high, and stability is good.

    本发明一种内河船舶领域船舶态势危险检测方法,所述方法包括如下步骤:建立内河船舶领域模型;通过所述内河船舶领域模型获取外部安全距离边界式;建立相对船体的坐标系,获取目标船舶坐标TS;通过目标船舶坐标TS获取目标船舶速度,通过目标船速度获取本船与目标船的相对速度;通过目标船舶坐标TS建立碰撞危险检测线表达式,通过碰撞预测表达式与外部安全距离边界方程式确定碰撞交点坐标;通过碰撞交点坐标和所述相对速度获取所述目标船舶的碰撞危险检测线与船舶领域安全距离边界交点的会遇时间;根据所述碰撞危险检测线与安全距离边界的位置关系和会遇时间对内河船舶态势危险等级划分,能够实时进行危险碰撞检测,安全性高且稳定性好。
