Hyperspectral image super-resolution reconstruction method and device and electronic equipment

The invention provides a hyperspectral image super-resolution reconstruction method and device and electronic equipment, and relates to the technical field of image processing, and the method comprises the steps: obtaining a training sample set, and a to-be-reconstructed target high-resolution multispectral image and a to-be-reconstructed target low-resolution hyperspectral image, a spatial degradation characterization network, a spectral degradation characterization network and a fusion network for image reconstruction are constructed, the spatial degradation characterization network and the spectral degradation characterization network are pre-trained at the same time, and then the fusion network, the pre-trained spatial degradation characterization network and the pre-trained spectral degradation characterization network are jointly trained. And finally, performing fusion processing on the target high-resolution multispectral image and the target low-resolution hyperspectral image by using the fusion netwo
