Abstract
The present invention discloses a high-resolution hyperspectral computational imaging method and system and a medium. The method of the present invention comprises: conducting spectral upsampling on an input RGB image Y to obtain an initial hyperspectral image X0; and inputting the initial hyperspectral image X0 into a pre-trained deep convolutional neural network guided by an imaging model, and conducting iteration computation to obtain a hyperspectral image X. The present invention can effectively achieve reconstruction of the RGB image to the high-resolution hyperspectral image and has the advantages of high reconstruction precision, high computational efficiency, little memory consumption and strong generalization ability.
