【摘要】 随着现代战争节奏的加快和军事科技的日新月异,利用基于虚拟战场环境的训练模拟器/系统来对士兵和指挥员进行训练的方式,正成为部队进行训练的一种重要的现代化手段。本文在分析和概括军事训练模拟系统国内外研究现状的基础上,对军事训练模拟系统中涉及的模型建立、碰撞检测以及特效生成等关键技术进行了研究。本文主要进行了以下几个方面的工作;1.在实现了高炮训练模拟系统地形建模和实体建模的基础上,重点研究了高炮训练模拟系统中实体运动模型的建立,设计并构建了高炮和飞机目标的运动模型。2.介绍了碰撞检测的定义和分类,讨论了训练模拟系统中的碰撞响应问题,重点研究了训练模拟系统中涉及的三种碰撞检测问题;弹丸与目标碰撞、模型拾取和地形匹配,并针对弹丸的碰撞检测,提出一种优化的碰撞预测策略,提高了场景中碰撞检测的效率。3.对战场特殊效果生成中广泛用到的粒子系统技术进行了介绍,研究了战场火焰和烟雾的生成方法,提出了一种模拟导弹尾焰的粒子系统。4.设计了具有对抗和联合协同训练功能的高炮训练模拟系统,实现了高炮武器系统的协同训练模拟。文章最后对本文的主要工作进行了总结,并提出了需要进一步研究的内容。更多还原

【Abstract】 As modern war is becoming faster and military technology is developing quickly, using military drilling simulators/systems based on virtual battlefield environment to train soldiers and commanders is becoming an important way for military drilling. Based on the analysis and generalization of status quo of international and domestic research on military drilling simulators/systems, this thesis discussed key technologies in military drilling simulators/systems such as modeling technology, collision detection and generation of special effects.The main work stated in this thesis focused on following aspects:1. Based on the realization of terrain modeling and entity modeling, the kinematic modeling in military drilling simulation system was studied in depth and the kinematic models of antiaircraft gun and aircraft were design and constructed.2. Definition and classification of collision detection were introduced and collision response in military drilling system was discussed. Three problems in collision detection in the drilling system were studied: collision between shell and objects, model pickup and terrain matching. An optimized forecast strategy for collision was put forward to improve the efficiency of collision.3. The particle system technology which is used widely in generation of special effects was introduced, and the methods for generation of battlefield fire and smoke were studied and a particle system for simulating the tail fire of missile was put forward.4. An antiaircraft gun drilling simulation system, which can realize the counterwork in training, was designed to train gun operator and commander of antiaircraft gun company together.At last, the main work of this thesis was summarized and more research work that needs to be done was also brought forward.更多还原
