Abstract

The invention provides a hyperspectral image panchromatic sharpening method, device and electronic equipment, which relate to the technical field of image processing, including obtaining a hyperspectral image to be processed and a panchromatic image registered with the hyperspectral image to be processed; Spectrum inference is performed on hyperspectral images to obtain hyperspectral images containing effective spectral bands, which are sequentially spliced ​​with panchromatic images, feature extraction and image restoration, and feature images of hyperspectral images to be processed are obtained; Pixels are added to the corresponding pixels of the hyperspectral image to be processed to obtain the target image. In this method, the target image is obtained by adding the characteristic image and the hyperspectral image to be processed, and the spectral characteristics of the obtained target image are not damaged, which alleviates the sharpness of the existing method for improving the spatial resolution of the hyperspectral image. The technical problem of spectral distortion of the transformed image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a hyperspectral image panchromatic sharpening method, device and electronic equipment. Background technique [0002] With the development of remote sensing applications, multispectral images have been difficult to meet the needs in many practical applications. Hyperspectral images with more bands have good application potential and have attracted more and more attention. Although hyperspectral images have high spectral resolution, their low spatial resolution has always been criticized. [0003] In the prior art, in order to improve the spatial resolution of hyperspectral images, there are two approaches: super-resolution and panchromatic sharpening. The former takes the low-resolution hyperspectral image as input, uses its inherent characteristics as prior information, and performs sharpening directly; the latter takes the low-spatial-resolution hyperspectral image and...
