摘要
高速运动物体的计算机红外成像仿真在国防、军事、遥感探测等许多领域有着广泛的应用价值。本文从红外物理学、流体力学、空气动力学以及传热学的基本理论出发 ,通过分析高速运动物体表面与流体之间的传热过程以及其它影响其红外成像的因素 ,提出了一个精确地反映气动加热作用机理的、简化的高速运动物体的计算机红外成像仿真模型。从实验结果看 ,该模型的红外仿真效果较理想。
Computer Simulations of Infrared Image for High speed Objects have found great applications in the National Defense,military area and remote sensing. In this paper,we account for all forms of heat transfer within the object as well as the dynamic interaction between the object's surface and the environment. Then we analyze the heat transfer process between the object's surface and the liquid based on the principles of infrared physics,hydrodynamics,aerodynamics and heat transfer. Finally a precise infrared image synthesis model for high speed objects is proposed. Experimental examples of the generated infrared images are presented,which illustrate the potential of our method.
