The invention relates to an inland river intelligent ship navigation encounter time prediction method, and the method comprises the steps: 1, building a coordinate system relative to a ship body, and obtaining the coordinate TS of a target ship; 2, obtaining the speed of the target ship through the coordinate TS of the target ship, and obtaining the relative speed of the ship body and the target ship; step 3, establishing a collision prediction line expression through the target ship coordinate TS; 4, determining a collision intersection point coordinate through the collision prediction expression and an inland ship domain safety distance boundary equation; 5, the meeting time of the collision prediction line of the target ship and the ship field safety distance boundary intersection point is obtained through the collision intersection point coordinates and the relative speed, and according to the inland river intelligent ship navigation meeting time prediction method, ship real-time collision prediction can be carried out, and stability is good.

    本发明涉及一种内河智能船舶航行会遇时间预测方法,所述方法为:步骤1:建立相对船体的坐标系,获取目标船坐标TS;步骤2:通过目标船坐标TS获取目标船速度,通过船体与目标船的相对速度;步骤3:通过目标船坐标TS建立碰撞预测线表达式;步骤4:通过碰撞预测表达式与内河船舶领域安全距离边界方程确定碰撞交点坐标;步骤5:通过碰撞交点坐标和所述相对速度获取所述目标船的碰撞预测线与船舶领域安全距离边界交点的会遇时间,本发明提供的一种内河智能船舶航行会遇时间预测方法,能够进行船舶实时碰撞预测,稳定性好。
