摘要:

针对图像制导炸弹半实物仿真中可见光视景的生成问题,利用Vega Prime仿真软件实现视景仿真系统。通过共享内存技术,使得视景仿真进程能够实时读取弹道仿真进程的弹道解算数据,并进行场景刷新;利用插值方法保证视景仿真中图像制导炸弹飞行弹道的平滑,利用LOD(Level of Detail)技术和视点中心海洋模型有效地节约了海洋视景仿真的仿真开销,保证了仿真帧率。通过实验验证该系统仿真帧率能够达到25帧/s,能够满足半实物仿真系统中实时仿真的要求。

Abstract:

Aiming at the simulation of visible light in the hardware in the loop simulation of image guided bomb, this paper realizes a visual simulation system by using Prime Vega simulation software. Through the shared memory technology, the visual simulation process can read the trajectory calculation data of the trajectory simulation process in real time, and refresh the scene. By using interpolation method, the smoothness of the flight trajectory of image guided bomb in visual simulation is ensured. The LOD (level of detail) technology and viewpoint center ocean model effectively save the simulation expenses of ocean scene simulation, which guarantees the simulation frame rate. Through experiment, the system simulation frame rate can reach 25 frames per second, which can meet the requirements of the real-time simulation in hardware in the loop simulation system.

Key words: visual simulation, image guided bomb, Vega Prime
