摘　　要：运动目标红外图像的真实感生成一向是红外场景生成中的难点。首先提出了一个运动目标的红外成像模型,它不仅结合了各种环境影响、目标表面几何形状、结构、热特性等因素,还考虑到内部热状态、以及目标在高速运动状态下的气动加热效果。另外,还设计了适用于红外图像的绘制方法,以提高红外图像的真实感效果并简化程序。在考虑到大气传输和传感器噪声对红外成像的影响后,给出了不同视点的运动目标的红外图像。从实验结果看,该模型及方法模拟效果真实,算法可靠。Realistic infrared image synthesis of moving object is infrared image synthesis model for moving object is presented which the difficulty technique to produce infrared scene. An considers various environmental factors, object surface geometry, structure, intrinsic thermal properties, internal heat conditions and aerodynamic heating due to its high-speed moving. Then the rendering method for infrared image is proposed and the parameter is designed meticulously in order to improve veracity and simplify processes. By incorporating the attenuation effect of atmosphere and the noise mechanism of infrared image sensor, the infrared images of the moving object in the scene from different viewpoint are generated. Experimental results illustrate the potential of our method.
