Abstract

The embodiment of the present invention discloses a spectrum extraction method and device of a hyperspectral acquisition system in the technical field of spectrum processing. The spectral extraction method of the hyperspectral acquisition system of the present invention includes the following steps: S1, scanning the spectral image, querying the sequence coding information corresponding to each color position in the spectral image; S2, extracting the sequence coding and storing the cloud number of the spectral image; S3. Input the designated spectrum number, retrieve the sequence code of the number, extract the sequence color image according to the sequence code, and synthesize the spectrum image for display. The present invention recognizes the color code in the spectral image when collecting the spectral image, and stores the colors of each position of the spectral image according to the coded order, and can directly synthesize the color image by inputting the spectral number when querying the spectral image. In this way, the mutual conversion between coding and spectral images is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of spectrum processing, and in particular, to a spectrum extraction method and device for a hyperspectral acquisition system. Background technique [0002] The spectrum is a pattern in which the dispersed monochromatic light is arranged sequentially according to the wavelength (or frequency) after the polychromatic light is split by a dispersion system (such as a prism or a grating). Light waves are produced by electrons moving inside atoms. The movement of electrons inside atoms of various substances is different, so the light waves they emit are also different. It is of great theoretical and practical significance to study the luminescence and light absorption of different substances. Has become a specialized discipline, that is, spectroscopy. [0003] Existing spectral images are often directly stored in the process of extraction and collection. Since there are many spectral images,...
