Problems solved by technology

[0003] Existing spectral images are often stored directly in the process of extraction and collection. Due to the large number of spectral images, a large amount of storage space is consumed during storage, which brings some inconvenience to the extraction of spectral images.

Abstract

The embodiment of the invention discloses a spectrum extraction method and device of a hyperspectral acquisition system in the technical field of spectrum processing. The spectrum extraction method ofthe hyperspectral acquisition system comprises the following steps: S1, scanning a spectrum image, and querying sequence coding information corresponding to each color position in a spectrum image; S2, extracting sequential codes to perform cloud numbering storage of the spectrum image; and S3, inputting a specified spectral number, calling a sequence code of the number, extracting a sequence color image according to the sequence code, synthesizing the sequence color image into a spectral image, and displaying the spectral image. According to the invention, when the spectral images are collected, the color codes in the spectral images are identified, the colors of all positions of the spectral images are stored according to the coding sequence, and when the spectral images are inquired, the color images can be directly synthesized by inputting the spectral numbers, so that the mutual conversion between the codes and the 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,...
