基于VP的三种思想下实现红外坦克目标的仿真对比研究

分析了三种截然不同的红外仿真思想,通过这三种方法的对比,提出了一种基于Vega Prime（VP）的红外仿真改进方法。之后在综合经验数据和热平衡模型的基础上,实现了有/无内热源下的坦克红外辐射场分布。同时给出了关键模块的模拟方法。最后通过三种方法下的仿真实验,模拟出了具有各自代表意义的坦克目标红外图像,通过与实拍红外图像的比较,得出了三种方法的优缺点及适用场合,实验结果真实可靠,有一定的工程应用价值。     

虚拟地球场景的可视化建模与仿真

从地球自身模型出发,提出了按季风带划分大气云层实现其转动的新方法。为了提高拟真性,探讨了大气散射的成因,研究了大气散射算法并通过GPU编程实现,最后给出了基于多重纹理混合映射的星空背景模型。实验结果表明,这些方法可以大幅提高整个场景的拟真度,同时具备高实时性。可以被广泛地用于空间作战、探测等仿真任务。

Abstract：

Starting from the earth model,a new method was proposed that the rotation of atmospheric could be divided by monsoon belt.In order to improve the fidelity,the reason caused atmospheric scattering was investigated,and the scattering algorithm was studied and implemented by GPU programming.At the end,the star scene model based on multiple texture blending was given.The result of experiment shows that these methods have not only given a substantial increase in fidelity,but also guaranteed real-time rendering.It can be widely used in simulation of space battlefield and exploration.
