MULTISPECTRAL IMAGE GENERATION METHOD, TERMINAL DEVICE AND COMPUTER-READABLE STORAGE MEDIUM

The present application is applicable to the technical field of image processing. Provided are a multispectral image generation method, a terminal device and a computer-readable storage medium. The method comprises: acquiring detection images; performing spatial classification according to the spectral similarity between the detection images, so as to determine a similar area; reconstructing a reconstructed multispectral curve of the similar area according to an average detected value of the similar area; and correcting the reconstructed multispectral curve according to the reconstructed multispectral curve of the similar area and the detection images, so as to obtain a target multispectral image of the similar area. A similar area of detection images is determined, and reconstruction is performed with respect to the similar area once, so as to obtain a reconstructed multispectral curve corresponding to the similar area, such that the calculation amount can be effectively reduced; and the reconstructed multis
