Abstract
A method for processing a hyperspectral image, comprising: a first correction step for extracting a curve of spectral dimension of an initial spaceborne hyperspectral cube image for low-pass filtering so as to obtain initial correction coefficients; an optimization step for optimizing and compensating the initial correction coefficients according to the ripple period of spatial dimension of the pixel in each band, so as to obtain the optimized correction coefficients of the hyperspectral cube image; and a second correction step for obtaining a corrected hyperspectral image based on the optimized correction coefficients.
