摘要
Most of current illumination models in realistic image synthesis are based on visible waveband. These models can not simulate the realistic image synthesis in infrared waveband. This paper presents a new quantity optics based illumination model for infrared image synthesis. The model adds a quantity radiation term of the object itself, E(Ε, T, λ1, λ2), based on the traditional illumination models such as Phong model. Where λ1 and λ2 are the initial and terminal wavelengths of the received waveband of detector, respectively, and Ε is the black-degree of the object, T is the absolute temperature of the object. This model is suitable both for the image synthesis in infrared waveband and for the image synthesis in visible waveband. When the received waveband locates in the visible waveband with low-temperature objects in the scene, this model returns to be the traditional illumination model. The new model can simulate the phenomena that the traditional illumination models cannot simulate, such as the different colors of iron during the process of fusion. Several realistic visible and infrared images in different scenes are rendered based on the model at last.
