Abstract :
Photoelectric parameters (such as: absorptivity, emissivity etc) are invariable according to different kinds of background, and they are useful in the type inversion, and further more target detection and recognition. Firstly, the heat balance equation of ground surface is constructed based on the heat energy exchange model of typical ground. Secondly, by considering the influence of air and background range, the relationship between the IR image and the surface temperature is gotten based on the black-body scaling test. Thirdly the heat balance function of background was established based on photoelectric parameters. Then the type inversion can be realized through suppose-verify method. Finally, the feasibility of algorithms is validated by real-measured IR images, and the inversion errors are analyzed.
