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。
The existing computer graphics lighting models are descriptions of the lighting effects of visible light. Since they do not reflect the infrared characteristics of the object, they can not provide a display model for the infrared simulation of the target. Based on the basic theory of infrared physics and heat transfer, this paper presents the target infrared imaging simulation model. The model successfully simulates the infrared characteristics of the target caused by the internal heat source. From the experimental results, the model of infrared simulation effect is better.
