Correlative Techniques of the Training System for Ship Handling Based on Virtual Reality

介绍了船舶操纵训练系统的构成 ,该系统使用多通道视频拼接的方法生成 360°视景 .提出了视景中海浪的建模方法 ,包括静止海浪模型和动态海浪模型 .通过采用局域网环境下的并行处理、增量发送、消息包定长定构和事件驱动接收等计算机网络与通信技术实现了具有较高的性能价格比的船舶操纵训练器 .还给出了白天航行、夜航。

The constitution of the training system for ship handling was introduc ed. In this system, multi-channel video signals were put together to generate a 360°scene. The methods of static sea wave mode^ling and dynamic sea wave modeli n g in the scene were also proposed. Furthermore, a ship handling simulator wa s de signed by using the computer network and communication technologies, such as par allel processing based on a local computer network, increment sending, fixed-len gth message package and event drive receiving. This simulator is of high perform ance to cost ratio. Simulation results under various conditions such as sailing in the daytime or at night as well as in frogs and stormy waves were also presen ted.
