Infrared And Low Light Level Image Fusion Technology Research

Fusion of infrared and low-level-light image becomes more and more popular in thefield of night vision. Thermal infrared(IR) sensors can provide high contrast image and beoperated normally in all weather while the infrared image has low resolution.low-level-light image has high resolution and quality while it is easily influenced by theenvironment. If we fusion these two kinds of image with some methods, we can improvethe observation ability of the night vision system greatly.In the first chapter, the definition, actuality and development foreground of fusion ofinfrared and low-level-light image are expatiated.In the second chapter, the basic theory of fusion of infrared and low-level-light imagewhich contains basic principle common arithmetic and evaluation of the effect areintroduced.In the third chapter, the matching and enhanced pretreatment of image fusion areparticular introduced. The process of telescoping-decompounding fusion arithmetic areexplained, the result of MATLAB emulator be observed.In the fourth chapter, the whole fusion system which contains optical system andelectronic system are emphasized.The last chapter summarizes the whole dissertation, and pointes out the problems inthe research that should be improved.
