Abstract

The invention is suitable for the technical field of image processing, and provides a multispectral image generation method, terminal equipment and a computer readable storage medium, and the method comprises the steps: obtaining a detection image; performing spatial classification according to the spectral similarity of the detection images, and determining similar regions; reconstructing a reconstructed multispectral curve of the similar region according to the detection average value of the similar region; and correcting the reconstructed multispectral curve according to the reconstructed multispectral curve of the similar region and a detection image to obtain a target multispectral image of the similar region. By determining the similar area in the detection image and performing primary reconstruction on the similar area to obtain the reconstructed multispectral curve corresponding to the similar area, the calculation amount can be effectively reduced, the reconstructed multispectral curve is corrected based on the detection image, and the accuracy of the generated multispectral image is effectively improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a method for generating a multispectral image, a terminal device, and a computer-readable storage medium. Background technique [0002] Multispectral image refers to the image formed when an object reflects and transmits light of multiple bands. Traditional multispectral imaging systems use devices such as gratings to perform spectroscopic scanning to obtain multispectral images. The traditional multispectral imaging system has the disadvantages of complex system structure and high price. In order to save costs and simplify the system, a multi-spectral imaging system based on LED lighting is currently proposed, which does not need to configure scanning moving parts and is convenient for band switching, which can avoid the phenomenon of metamerism. [0003] The current multi-spectral imaging system based on LED lighting usually uses a few bands of ...
