摘要
实弹射击系统是一种行之有效、可以直观真实地反映操作手射击水平的训练和考核系统,但也有保障条件高、成本昂贵、改造困难、难以进行复杂条件下的训练考核等缺点,为了解决现有的虚拟射击系统中光学模拟枪逼真度不高的问题,采用微机电系统传感器和软件技术设计了一种新的枪支模型。根据仿真枪支上安装的磁场传感器和加速度传感器测量值算出子弹的初始状态,结合弹道方程对子弹在三维空间中的运行轨迹进行计算,最后利用虚拟目标简化和场景分割方法设计算法对子弹命中进行实时判定。改进模型实时性好、易于实现、逼真度高,具有一定的商业应用推广价值。
The live shooting system is an effective training and assessment system which is able to intuitively and truly reflect operators' shooting level,but has such shortcomings as high security conditions,expensive cost,difficult transformation and training assessment under complex conditions.In order to solve the defect that the fidelity of optical simulation gun is poor in the existing virtual shooting system,a new firearm model based on micro-electro-mechanical system (MEMS) sensor and software technology was presented.The initial status was calculated through measured values of magnetic sensor and acceleration sensor installed on the simulation firearm model for calculating the running track in three dimension space through ballistic equation,and the real-time shooting judgment was made by virtual target simplify and scene segmentation method at last.The improved model has good timeliness,easy implement,high fidelity,and excellent commercial application value.
