基于虚拟现实技术的船舶消防培训系统

摘要

为提高船舶消防培训的效率和水平,节约训练成本,设计消防培训系统整体架构.运用三维建模技术建立固定水灭火系统、固定二氧化碳灭火系统及消防员装备穿戴模型.使用反向动力学原理实现虚拟人的动作模拟.使用粒子系统实现火焰和二氧化碳的雾化效果.使用碰撞检测技术判断虚拟人与设备之间、设备与设备之间、二氧化碳与火焰之间是否产生相互作用.培训过程中,针对学员操作给出具体提示信息,帮助学员完成操作训练.测试结果表明,所开发的系统培训效果良好,可应用于消防培训.%In order to improve the efficiency and level of ship fire-fighting training and save training cost, the overall framework of fire-fighting training system is designed.The fixed water-based fire-extinguishing system, the fixed CO2-based fire-extinguishing system and the model of fireman equipment clothing are built by 3D modeling technology.The motion simulation of virtual human is realized by the theory of inverse dynamics.The atomization of fire and CO2 is realized by the particle system.By the collision detection technology, whether the interactions generate between virtual human and equipment, between equipment and equipment and between CO2 and fire is determined.In the process of training, for student operation, the specific prompt information is given to help students complete operation training.Test results show that the developed system has good training effect, and can be applied to fire-fighting training.
