摘　　要：为使驾驶员能够识别出航道存在的危险,确保船舶航行安全,研究虚拟环境下船舶安全航行路径智能规划仿真方法。在虚拟环境下,基于船舶航道高程信息,利用连续极小泛函序列方法获取船舶航行航道等距网格数据,利用对象图像渲染引擎处理航道网格数据,得到航道地形模型。利用Solid Works软件,通过创建基准面、生成船舶船体型线以及构建船体曲面模型等过程生成船舶三维模型。根据生成的航道地形模型与船体模型,提出适用于三维空间路径规划的空间分层路径规划方法,通过逆向逐步搜索路径过程得到船舶安全航行路径规划结果。实验结果显示,该方法生成的航道地形与船体模型较为完善,路径规划过程中能够有效躲避固定障碍物与移动障碍物,既保障船舶航行安全性又确保航程最短。In order to enable drivers to identify the dangers present in the waterway and ensure the safety of ship navigation,an intelligent planning and simulation method for ship safe navigation path in a virtual environment is studied.In a virtual environment,based on the elevation information of ship navigation channels,the continuous minimum functional sequence method is used to obtain equidistant grid data of ship navigation channels,and the object image rendering engine is used to process the channel grid data to obtain the channel terrain model.Using Solid Works software,generate a three-dimensional model of a ship by creating a reference plane,generating ship hull lines,and constructing a ship surface model.Based on the generated channel terrain model,a spatial layered path planning method suitable for three-dimensional spatial path planning is proposed,and the results of ship safe navigation path planning are obtained through the reverse step-by-step search path process.The experimental results show that the channel terrain and ship model generated by this method are relatively complete,and can effectively avoid fixed and moving obstacles during the path planning process,ensuring both the safety of ship navigation and the shortest voyage.
