Infrared visible light fusion recognition system and method based on modal difference feature guidance

The invention discloses an infrared visible light fusion recognition system based on modal difference feature guidance, which comprises a double-flow backbone network module, an illumination heat perception module and a cascade region proposal module, and is characterized in that the double-flow backbone network module comprises an infrared feature extraction unit, a visible light feature extraction unit and a feature guidance unit, the infrared feature extraction unit obtains different-scale infrared features of the original infrared image, and the visible light feature extraction unit obtains different-scale visible light features of the visible light image; the feature guiding unit obtains weighted infrared features and weighted visible light features; the illumination popularity sensing module obtains the credibility weight of the visible light feature and the credibility weight of the infrared feature; and the cascade region proposing module is used for obtaining an identification result of the target.
