| The technique of image fusion makes up the lack of single sensor, it has the virtue of improving performance of systemic detection,improving roboticized degree,reducing the systemic cost,improving objectivity and validity of detection identifying ,so image fusion is the hotspot of research now. If the people want to achieve the aim of the better effect of fusion, first, they must analyze the difference of feature of radiation of target,the difference of feature of transmission of radiation,the difference of feature of imaging and the difference of character of image in the different bands , on base of the analysis the fusion arithmetic is researched, the effect of image fusion is toned by using the commutative information and the redundancy information, the people can achieve the good effect of fusion and the fusion has the pertinence on base of target feature and research of fusion arithmetic are linked.The paper researches the theory that the analyzing of feature of target need of infrared radiation, then the paper researches the feature of radiation transmission and compute the radiation contrast of target and background, at the same time the paper analyzes the feature of the radiation contrast of target and background and the image feature that the radiation contrast of target and background arose, then the paper expounds the image feature using he bar chart,mean,standard deviation,local entropy,congruity of entropy,roughness concentration of multi direction, at last the paper bring forward the fusion arithmetic of double bands infrared on base of fundamentals of Plank and bring forward the fusion arithmetic double bands infrared on base of feature of target. the paper realizes the fusion arithmetic using MATLAB, the effect is better, the fusion image has the abundant detail information , the target is clarity, the feature of target is generally reflected, the target is identified and detected in easy. Besides the fusion arithmetic has the pertinence. |
