为提升船舶在复杂航行环境中的安全，提出基于虚拟现实的船舶航行复杂周围环境图像三维仿真方法。该方法使用虚拟现实技术中的Vega Prime虚拟现实开发工具，依据海洋、船舶相关数据与图像，使用Crertor工具建立flt静态三维模型库，从该模型库内导出船舶三维模型所需数据后，使用Vega Prime虚拟现实开发工具的LynXPrime图形界面，对船舶航行复杂周围环境的水体、海浪等进行建模并进行纹理制作后，再通过实时驱动、视景仿真驱动以及仿真交互程序运行，实现船舶航行复杂周围环境图像三维仿真模型的交互。实验结果表明，该方法可有效对船舶航行复杂周围环境的洋流流向、流速、海水温度进行三维仿真。同时也可对船舶航行环境内其他船舶进行红外视景可视化，且应用效果较佳。
To improve the safety of ships in complex navigation environments, a three-dimensional simulation method based on virtual reality for ship navigation complex surrounding environment images is proposed. This method uses the Vega Prime virtual reality development tool in virtual reality technology. Based on ocean and ship related data and images, the Creator tool is used to establish a FLT static 3D model library. After exporting the required data for ship 3D models from this model library, the LynXPrime graphical interface of the Vega Prime virtual reality development tool is used to model and texture the complex surrounding environment of water bodies, waves, etc. in the ship's navigation, Through real-time driving, visual simulation driving, and simulation interaction program operation, the interaction of three-dimensional simulation models of complex surrounding environment images for ship navigation is achieved. The experimental results show that this method can effectively simulate the three-dimensional flow direction, velocity, and seawater temperature of the complex surrounding environment of ship navigation. At the same time, it can also visualize the infrared scene of other ships in the ship navigation environment, and the application effect is better.
