基于HTC VIVE的船舶固定水灭火模拟训练系统

Training Simulator for Fixed Water Based Ship Fire Fighting Built on HTC VIVE

鉴于消防培训实操教学和训练比较困难,且成本较高,开发船舶固定水灭火模拟训练系统。运用三维建模技术建立消防泵、消防栓等固定水灭火设备模型,利用HTC VIVE头盔和Unity 3D引擎设计实现船舶虚拟场景的三维可视化与交互操作,利用贝塞尔曲线实现虚拟场景内学员的位置瞬移,通过碰撞检测实现学员对虚拟设备的操作,采用A*算法虚拟辅助船员进行路径规划。测试结果表明,该系统的沉浸感和交互性强,可用于消防培训。

A fixed water based ship fire-fighting training simulation system is developed for facilitating training program arrangement and reducing training costs. Fire pump,fire hydrants and other fixed water fire-fighting equipment models are established by the three dimensional modeling technology. The 3 D visualization and interactive operation of ship virtual scene is realized by means of the HTC VIVE helmet and the Unity 3 D engine. Motion of the trainee in the virtual scene is implemented with Bezier curve function. The collision detection is used to realize operation of virtual devices. The A＊algorithm is applied to make a plan of the paths of the virtual crew. Tests show that the developed system has strong sense of immersion and interactivity and,effective for fire-fighting training.
