Remote sensing image super-resolution reconstruction method, processing device and readable storage medium

Abstract

The invention discloses a remote sensing image super-resolution reconstruction method, a processing device and a readable storage medium. The remote sensing image super-resolution reconstruction method comprises the steps: preprocessing an image, constructing a generative adversarial network model, performing optimization, transfer learning and other processing on the generative adversarial network model, and finally obtaining a network model capable of outputting a super-resolution remote sensing image corresponding to an input low-resolution remote sensing image. According to the remote sensing image super-resolution reconstruction method, the generative adversarial network model is optimized by removing batch normalization of the residual module in the convolutional neural network; andthe generative adversarial network model is trained by using a transfer learning method, so that the problem that the model is difficult to train due to a small number of remote sensing images and lowquality is solved, and the performance index and the visual effect of a reconstruction result are improved while the memory consumption (about 40%) is reduced.

Problems solved by technology

[0008] 1. Unlike the super-resolution reconstruction requirements of optical natural images, the super-resolution reconstruction tasks of remote sensing images in actual situations often require large-scale reconstruction such as 4 times and 8 times. Super-resolution reconstruction networks based on ordinary neural networks are mostly It is only suitable for reconstruction tasks with small magnifications (2x, 3x), and it is difficult to obtain good reconstruction results in real application scenarios of remote sensing images;

[0009] 2. At present, most super-resolution reconstruction networks based on deep learning methods use batch normalization (BatchNormali
