Reconstruction enhancement method and device for hyperspectral remote sensing data image

The invention provides a reconstruction enhancement method and device for a hyperspectral remote sensing data image. The method comprises the following steps of pre-processing the original hyperspectral remote sensing data; constructing a CVAE-GAN model, using the processed original hyperspectral remote sensing data for CVAE-GAN model training, and after training is completed, using the model for data expansion; performing compression reconstruction processing on the expanded hyperspectral remote sensing data by applying a data compression algorithm to obtain the reconstructed data corresponding to the original hyperspectral remote sensing data; and constructing a Hyper-SR model, and training by using the image data before and after reconstruction to realize the high-quality enhancement of the reconstructed image. The method is suitable for performing high-quality enhancement on the distorted hyperspectral remote sensing data after compression and reconstruction, the original data information can be reserved
