为提升船舶驾驶人员及船员的船舶整体认知以及海况应对能力，确保船舶航行以及作业安全，设计基于虚拟现实技术的船舶航行实景三维模型。按船舶航行需遵循的物理定律以及原理，建立船舶航行运动姿态数学模型，并通过3Dmax构建船舶航行环境实体以及地形模型，利用PM海浪谱法构建海表面三维模型，而后通过Unity3D虚拟现实仿真软件驱动调整构建的三维模型，并对所构船舶三维模型采用改进混合包围盒法实施碰撞检测，把地形以及海浪等实际数据信息融入到导入的模型之中，仿真模拟船舶航行实景，实现人机交互。实验结果表明，基于虚拟现实技术实现的船舶航行实景三维模型，可较为真实模拟船舶航行实景，为确保船舶航行以及作业安全提供可靠参考与保障。
To enhance the overall understanding and ability to respond to sea conditions of ship drivers or crew members, and ensure the safety of ship navigation and operations, a 3D model of ship navigation based on virtual reality technology is designed. Construct a 3D simulation technology architecture for virtual reality ship navigation models, follow physical laws and principles for ship navigation, establish a mathematical model of ship navigation motion posture, and use 3Dmax to construct ship navigation environment entities and terrain models. Use PM wave spectrum method to construct a 3D model of the sea surface, and then use Unity3D virtual reality simulation software to drive and adjust the constructed 3D model. Implement collision detection on the constructed ship 3D model, integrate actual data information such as terrain and waves into the imported model, simulate the ship navigation reality, and achieve human-machine interaction. The experimental results show that the three-dimensional model of ship navigation based on virtual reality technology can simulate the real ship navigation scene more realistically, providing reliable reference and guarantee for ensuring ship navigation and operational safety.
