Problems solved by technology

[0002] The current mainstream super-resolution algorithms include nearest neighbor interpolation, bicubic interpolation, SRCNN, VDSR, SRGAN, etc., but considering that remote sensing images contain rich high-frequency information, the reconstruction quality of the edge part of high-frequency information is relatively poor with the current algorithm. And there is a problem of missing edge details during image reconstruction

Abstract

The invention provides a remote sensing image super-resolution reconstruction method and device and a storage medium, and the method comprises the steps of obtaining an original remote sensing image through a satellite, and carrying out the cutting of the original remote sensing image, and obtaining a plurality of remote sensing cut images; and respectively carrying out down-sampling processing on the plurality of remote sensing cut images to obtain low-resolution images corresponding to the remote sensing cut images. Compared with an existing algorithm, the invention has a better restoration effect in remote sensing image super-resolution reconstruction, so that the reconstructed image is clearer, more texture details are restored, the edge contours of buildings, roads and vegetation are clearer, the reconstruction quality of the edge part of high-frequency information is improved, and meanwhile, the PSNR is greatly improved, the SSIM is also slightly improved, so that the problem of edge detail loss during image reconstruction is solved.
