Abstract

The invention provides a multi-spectral image sharpening method, device and equipment and a storage medium, and relates to the technical field of image processing. The method comprises the following steps: respectively preprocessing a multispectral image and a panchromatic image matched with the multispectral image to obtain a preprocessed multispectral image and a preprocessed panchromatic image;splicing the preprocessed multispectral image and the preprocessed panchromatic image to obtain a to-be-processed image; and processing the to-be-processed image by adopting a preset multi-scale detail injection network model to obtain a high-spatial-resolution multispectral image output by the multi-scale detail injection network model. Injecting into a network model through multi-scale details;the convolution layer of each scale extracts the detail information of the multispectral image under the scale, the preprocessed multispectral image is combined to obtain the multispectral image withhigh spatial resolution, the detail information of the multispectral image is extracted, the sharpening effect is improved, and the sharpening efficiency of the multispectral image is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a multi-spectral image sharpening method, device, equipment and storage medium. Background technique [0002] A multispectral image is an image that contains multiple bands, each band being a grayscale image. Multispectral images are widely used in disaster detection, intelligence collection, geological detection and other fields. Therefore, it is becoming more and more important to improve the spatial resolution of multispectral images. [0003] In related technologies, multispectral images and panchromatic images are collected through satellites, and the controller uses wavelet transform and Laplacian pyramid to extract detailed information in the panchromatic images, and inserts the detailed information into the multispectral images to obtain high-resolution images. Spatial-resolution multispectral imagery. [0004] However, in related technologies, wavelet ...
