The invention discloses a ship route and speed combined planning method, and relates to the field of intelligent ships, and the method comprises the steps: obtaining an improved dynamic Theta * algorithm through real-time detection of meteorological data on the basis of a standard Theta * algorithm; an improved dynamic Theta * algorithm is used for determining an initial route which reaches the target point from the starting point and does not pass through the obstacle grid, and the real-time meteorological data at all the positions meet the ship passing condition. And optimizing the initial route by using a route and speed joint optimization method to obtain an optimized route and speed. The initial route is planned by detecting the obstacles on the navigation path and the dynamic meteorological data in real time, the obstacles and severe weather such as typhoons can be accurately avoided, the navigation safety is greatly improved, and a solid foundation is laid for subsequent optimization steps.
本申请公开了一种船舶航线航速联合规划方法,涉及智能船舶领域,该方法包括:本申请在标准Theta*算法的基础上通过实时检测气象数据,得到改进的动态Theta*算法。利用改进的动态Theta*算法确定从起点到达目标点不经过障碍物网格且各个位置处的实时气象数据均满足船舶通行条件的初始航线。利用航线航速联合优化方法对初始航线进行优化,得到优化后航线及航速。通过实时检测航行路径上的障碍物及动态气象数据来规划初始航线,能够精准避开障碍物及台风等恶劣天气,极大地提升了航行的安全性,为后续优化步骤奠定了坚实的基础。
