车辆红外图像的计算机仿真

真实的车辆红外图像的生成是红外场景生成和实现其虚拟漫游的关键技术，它也同时在遥感测量、交通管理、车辆设计、国防和军事等众多领域有着广泛地应用。分析了影响地面车辆红外特征的各种环境及内部因素，建立了车身表面热平衡方程，并以此提出车辆三维红外成像模型。还模拟了大气传输过程对红外成像的影响，并运用计算机图形学理论设计适合红外图像的绘制方法。最后给出了地面车辆红外图像的模拟结果。从实验结果看，该方法模拟效果真实，算法可靠。

Computer Simulation of Vehicle Infrared Images

Realistic infrared image synthesis of the vehicles is the key technique for producing infrared scene and realizing its virtual roam. In addition,it has been heavily used in remote sensing, traffic management, vehicle design, the national defense and military affairs. This paper analyzes various environmental and inner factors affecting the infrared characterics of the vehicles. Then a thermal equilibrium equation of the body surface is established and the 3D infrared image synthesis model for vehicles is presented. Furthermore the atmosphere effect is incorporated. By using the techniques of Computer Graphics, the rendering method for infrared image is proposed and the infrared images of the vehicles are generated at last. Experimental results illustrate the potential of this method.
