摘要
现有计算机图形学的光照模型，都是对可见光的光照效果的描述，由于它们没能反映物体的红外特性，因而不能为目标的红外仿真提供显示模型。本文从红外物理及传热学的基本理论出发，提出目标的红外成像仿真模型。该模型成功地模拟了由内热源引起的目标的红外特征。从实验结果看，模型的红外仿真效果较理想。
Most of the current illumination models for realistic image synthesis are based on optics of visual range. These models cannot be used to simulate the infrared signature of objects, so they can't meet the requirements of infrared image synthesis. This paper proposes a simulation model of object's infrared signature based on infrared physics and heat transfer, which successfully simulates the infrared signature of a object having the internal heat source.The paper first presents the theoretic model integrating conduction heat transfer,surface heat diffusion and infrared radiation. Initial results demonstrate the potential of our method.
