The invention is suitable for the technical field of optics, and provides a spectral image determination method and device, a terminal and a storage medium. The spectral image determination method comprises the following steps: acquiring an original multispectral image of a target object; determining original spectral response value information of each original spectral band in n original spectral bands corresponding to the original multispectral image, wherein n is a positive integer greater than 0; acquiring a preset conversion relation corresponding to the original multispectral image; based on the preset conversion relation and the original spectral response value information of each original spectral band in the n original spectral bands, performing conversion to obtain target spectral response value information of each target spectral band in m target spectral bands, wherein m is a positive integer greater than 0; and determining a target spectral image of the target object according to the target spectral response value information. According to the embodiment of the invention, the spectral image of the specific spectral band can be reconstructed.
Description
technical field [0001] The present application belongs to the field of optical technology, and in particular relates to a determination method, device, terminal and storage medium of a spectral image. Background technique [0002] Spectral imaging data is a data source for map-spectrum integration, which includes image information and spectral information at the same time, and can give spectral intensity data of each pixel in each band; spectral imaging technology can be used for qualitative and quantitative analysis of objects, as well as positioning analysis etc. Spectral imaging technology can be divided into three categories according to the spectral resolution from low to high: multispectral imaging, hyperspectral imaging and hyperspectral imaging technology. Spectral imaging technology has not only spectral resolution ability, but also image resolution ability, which can be applied to the identification of geological minerals, vegetation ecology, and military target re...
