Technology of modeling and simulation for dynamic IR image sequences

The technology of modeling and simulation for dynamic IR image is discussed. Due to the complexity of the target, background and atmosphere, the difficulty for the modeling and simulation of infrared image is great. The design idea, achievable way and software frame for the modeling and simulation software of IR image sequences in SGI workstation are introduced. The imaging under various radiation influence is analyzed and the calculation formula of radiation is provided. In addition, the passive scene and active scene are analyzed separately. Then the calculation methods of temperature in passive scene are provided, and the functions of the scene model, atmospheric transmission model and physical property of materials acting on IR imaging are explained. Finally several examples of the modeling and simulation for infrared image sequences as well as the synthetic estimation are presented. 
