为仿真场景景物红外特征和红外高光现象，根据红外成像基本原理改进了计算机图形学中的可见光光照模型，提出了基于Blinn-Phong模型的红外辐照模型，在可见光Blinn-Phong反射模型中引入自发辐射项并考虑场景中各种辐射源与对象表面间辐射能量的传递，使对象表面辐照效果符合相应规律。在仿真实现方面，提出基于几何特征的反射区域辐射能量计算方法，根据景物几何特征确定反射区域，由入射点处的自发辐射和材料在长波波段的漫反射率、镜面反射率以及反射点处的法向量、探测器位置、朝向等信息计算反射点相对探测器的总辐射能量，实现红外高光效果模拟。分析验证了所提出的红外辐照模型和高光效果模拟方法的有效性。

In order to simulate infrared feature of the scene and infrared high light phenomenon, the visual illumination model in computer graphics is improved according to the principle of infrared imaging, the visual Blinn-Phong model is improved and remodeled into an infrared illumination model by introducing self radiation, considering the energy transfer between radiation sources and the object surface in the scene, and making the imaging effect of the object surface conform with corresponding law. In the aspect of realizing simulation, a new radiation energy computing method of the reflection area is proposed to simulate infrared high light effect based on the geometry features of the target. The reflection area is determined according to the target geometry, then infrared high light effect of the target is simulated by computing total energy which is calculated by the information of self-radiance of the incidence point, diffuse reflection rate and specular reflection rate of the material, and normal vector of the reflection point, the position and orientation of the detector and so on. It shows the validation of infrared illumination model and the simulation method of high light effect.
