摘要
针对舰船目标红外仿真的需求,对红外仿真的流程及关键技术进行了研究。论文简要介绍了一种基于海洋背景下的舰船及其尾迹的红外仿真方案。利用将物理信息模型与几何模型绑定的方法,充分运用GPU的着色器技术实现红外辐射并行实时计算,有效提高了红外场景生成的实时性。论文将温度场的实时计算放入GPU中,可实时实现由温度变化引起的目标辐射能量的变化。同时,论文提出一种尾迹建模方法,提高了整个场景的真实性。红外仿真结果尚能令人满意,为红外成像的仿真及演示提供了一种有效的手段。
According to the demand of warship target infrared simulation ,the process and key techniques of infrared simulation studied .The paper studied the infrared simulation of warships under different statuses and simulated the ship wake .By combining the physical information model and geometry model ,the operation efficiency was greatly improved .In this paper ,the real-time calculation of temperature field was calculated in the GPU ,which could realize real-time change of target radiation energy caused by temperature change .What＆#39;s more ,the paper proposed a wake modeling method ,which im-proved the fidelity of the whole scene .The results were satisfactory ,which provided an effective means for infrared simula-tion .
