The invention provides a
small target detection method and
system based on aligned visible light and
infrared images, and relates to the field of target detection, and the method comprises the steps: obtaining a visible light image and an
infrared image of a to-be-detected
small target; inputting a visible light image and an
infrared image into the trained detection model, firstly, respectively performing multi-scale
feature extraction on the visible light image and the
infrared image by adopting a double-
branch structure, and in the extraction process, performing multi-scale
feature extraction on the visible light image and the
infrared image through interactive collaborative learning of the visible light image and the
infrared image; the method comprises the following steps: firstly, carrying out feature alignment,
modal interaction correction and multi-scale feature enhancement between two modals to obtain enhanced visible light features and infrared features, then carrying out
feature fusion, and finally, carrying out
small target positioning and classification by utilizing the fused features. According to the method, feature level alignment of image pairs is realized by using deformable
convolution and
modal interaction correction, so that the features of visible light and infrared images are effectively and fully interacted and fused, and the accuracy of a detection
algorithm is improved.
