Abstract
A semantics-based high resolution reconstruction method of a nighttime light remote sensing image includes: constructing a sample data set; the sample data set includes a plurality of data groups, and each data group includes a LR NTL image, and a HR NTL image and light semantics information consistent in spatial position with the LR NTL image; constructing a reconstruction model; performing training and validation on the reconstruction model by using the sample data set to obtain an optimized reconstruction model; and taking a to-be-reconstructed LR NTL image and light semantic information corresponding to the to-be-reconstructed LR NTL image as an input of the optimized reconstruction model, and outputting, by the optimized reconstructed model, a HR NTL image obtained through resolution reconstruction.
