Target detection method combining visible light image and infrared image

The invention relates to a target detection method combining a visible light image and an infrared image, and belongs to the technical field of image processing based on deep learning. Firstly, a visible light image and an infrared image are respectively input into a feature extraction module, and global features of the visible light image and the infrared image are extracted; and inputting the visible light image into an illumination sensing module, and extracting illumination information. Secondly, the features obtained in the first step are input into a mutual information module, so that redundant information of visible light image and infrared image features is reduced; secondly, the features obtained in the first step are input into a feature fusion module to fuse complementary information of the visible light image features and the infrared image features, and a fused feature map is obtained; and finally, inputting the illumination information obtained in the step 2 and the feature map obtained in the s
