Video image fusion-processing system

The invention discloses a video image fusion-processing system. The video image fusion-processing system comprises an image acquiring module, an image fusion-processing module, an image evaluating module, wherein the image acquiring module is used for realizing format conversion between infrared image and visible light which are acquired by two coaxial sensors in real time; the image fusion-processing module is used for performing frame-by-frame processing on the format-converted infrared image and visible light image; if the infrared image is not matched with the visible light image, performing image rectification and then performing fusion-processing to obtain a fused image; the image evaluating module is used for calculating various image indexes before and after fusing, and analyzing the fused results. Through the fused images, the video image fusion-processing system can be used for obtaining a certain strengthening effect under a greasy weather condition or a night condition.
