Image reconstruction method and device, electronic equipment and storage medium

The invention provides an image reconstruction method and device, electronic equipment and a storage medium, and relates to the field of image processing. The method comprises the following steps: acquiring an initial hyperspectral image, taking the initial hyperspectral image as a current hyperspectral image, and decomposing the current hyperspectral image to obtain an initial spectral basis and initial spatial representation information; performing spatial semantic feature extraction on the initial spatial representation information based on a deep attention mechanism to obtain target spatial representation information and further obtain a second hyperspectral image; updating the current hyperspectral image based on the second hyperspectral image until the feature relative error is smaller than a preset threshold value; and taking the second hyperspectral image obtained when updating is finished as a target reconstruction hyperspectral image corresponding to the target compression imaging system.
