Abstract


The simulation of infrared scene by computer’s modeling capability is one of the important researches in the field of infrared (IR) simulation technique. Being involved with so many modern high-tech approaches , the technique of scene simulation has greatly widened the visual field of human beings and promoted our ability. It plays an important role in scientific research.The dynamic IR scene generation technique can reduce the cost of developing a new weapon system. All of these lead to its great theoretical significance and wide application perspective.This thesis is focus on how to use computer to generate dynamic IR images. A method of the IR sence simulatoin based on Multigen Creator and Vega is deseribed, which include the creating of three-dimensional(3D) model and IR modeling.Firstly, Development situation of IR scene simulation is introduced. The method is proposeda ccording to the function module of the system.Sceondly, researching infrared radiation characteristic of target and backgrouds, the attenuation characteristic of inrfaerd radiation through is analyzed and the atmospheric permeance and infrared receiver effects of inrfared radiation is given. The design ideas and implementation method to generate dynamic IR scene with computer are addressed.Thirdly, the 3D models of flight are designed on the basis of the study of modeling techniques by Creator. The instance skill is used to reduction the system resources.Fourthly, as the process of IR image recvied by detector, TMM is used to give texture materials attribute. The method to build atmospheric permeance by MAT is researched. Senso Vision and Sensor Works is introduced through this thesis.Finally, a MFC-based Vega exploitation is complied, the emphasis is analysised; Screen capture and Zlib method is used to capture IR images, the real-time transmit and interaction control have good efficiency.The IR scene images are ture to nature, and the transmission rate of Pordueing IR images is greatly increased. The research methods and key technology in this paper are valuable for the future research on dynamic simulation of target’s IR images.
