A Quantity Optics Based Illumination Model for Infrared Image Synthesis

现有的大多数光照明模型都是基于可见光波段的 ,它们无法模拟物体在红外波段的成像 .该文提出了一种新的基于量子光学的红外成像光照明模型 ,该模型在传统光照明模型的基础上加了一项物体本身的量子辐射项E(ε0 ,T,λ1 ,λ2 ) ,其中 λ1 ,λ2 为探测器的两端波长 ,ε0 为物体表面的发射率 ,T为物体的绝对温度 .该模型同时适用于红外波段和可见光波段成像 ,当接收波段在可见光域且场景中物体的表面温度较低时 ,该模型回归为传统的光照明模型 .该模型还能模拟传统光照明模型所不能模拟的现象 ,如钢铁在熔化过程中显示出来的不同颜色 .文中最后绘制了几个不同场景下真实感较强的可见光和红外图像 .

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 0 ,T,λ 1 ,λ 2 ), based on the traditional illumination models such as phong model. Where λ 1 and λ 2 are the initial and terminal wavelengths of the received waveband of detector, respectively, and ε 0 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.
