基于HMD的船舶虚拟消防训练系统设计及实现

Design and Realization of Ship Virtual Fire Training System Based on HMD

针对目前真实环境下船舶消防训练存在的不足及虚拟现实技术在教育培训中的优势和应用,开发基于头戴显示器(Head Mounted Display,简称HMD)的船舶虚拟消防训练系统。系统以Unity3D虚拟现实开发引擎为平台,采用客户端/服务器模式,支持多人协同操作,运行终端为HTC Vive虚拟现实硬件。系统将火灾扩散机理,消防射水动力学方程与粒子系统结合,完成模型建立及可视化过程,提高消防训练场景的真实感。系统最终运行在虚拟现实硬件终端,经过学员体验和测试,得到较好的反馈结果。

Aiming at the shortcomings of ship fire training in real environment and the advantages and application of virtual reality technology in education and training,the virtual fire training system of ship based on head mount display(HMD) is developed.The system is developed using the Unity 3D Virtual Reality Development Engine as a platform,using client/server mode,supporting multi-person cooperative operation,and running the terminal for HTC Vive virtual reality hardware.The system combines the fire diffuser mechanism,the water shooting hydrodynamic equation and the particle system;completes the model establishment and visualization process,and improves the realism of the fire training scene.The system finally runs in the virtual reality hardware terminal.Through the experience and the test,the good feedback results are obtained.
