【摘要】：针对海上消防实训困难,费用昂贵的问题,基于开源场景图形(OpenSceneGraph,OSG)渲染引擎和Bullet物理引擎开发了海上消防三维仿真系统。设计中使用事故船舶视口和消防船舶视口双视口的观察形式来增强仿真效果;运用OSG粒子系统模拟实现爆炸失火和消防水柱的粒子效果;通过实时计算火焰和水的粒子参数并根据碰撞力学运用Bullet检测水粒子和火源的碰撞,从而来实现对火势的控制。实验结果表明,OSG和Bullet的结合实现了实时控制粒子系统来模拟消防场景,并具有逼真的仿真效果。上述仿真系统使受训人员在近似实战的环境中训练,提高训练效率,实现训练数字化,降低训练成本,同时提升受训人员的灭火救援和指挥决策能力。
[Abstract]:Aiming at the difficult and expensive training of offshore fire fighting, a 3D simulation system for offshore fire fighting is developed based on Open scene Graph-OSG rendering engine and Bullet physical engine. In the design, we use the observation form of accident ship and fire ship view to enhance the simulation effect, and use OSG particle system to simulate the particle effect of explosion misfire and fire water column. By calculating the particle parameters of flame and water in real time and using Bullet to detect the collision between water particle and fire source according to collision mechanics, the fire potential can be controlled. The experimental results show that the combination of OSG and Bullet realizes the real-time control particle system to simulate the fire fighting scene and has a realistic simulation effect. The above simulation system enables trainees to train in a similar actual combat environment, improve training efficiency, realize training digitalization, reduce training cost, and improve the ability of fire fighting and rescue and command decision-making of trainees at the same time.
