摘要
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.
