Method for utilizing of hyperspectral image using optimal band ratio

摘要

The present invention comprises the steps of: (a) inputting the hyperspectral observation value Y of each of a plurality of predetermined points to the hyperspectral observation value input module 310; (b) A photographed image having hyperspectral information is input to the photographed image input module 210, and the superspectral photographed value I(x) which is a pixel value for a plurality of wavelengths x at each of the predetermined plurality of points ) Is confirmed; (c) The band ratio calculation module 320 selects any two pairs of wavelengths (λ ₁ , λ ₂ ) among the plurality of wavelengths (x) included in the hyperspectral photographing value, and hyperspectrals for each Checking the photographed values (I(λ ₁ ), I(λ ₂ )); (d) The band ratio calculation module 320 calculates a band ratio (X) by dividing any one of the identified two hyperspectral photographed values (I(λ ₁ ) and I(λ ₂ )) into another. step; And (e) the regression analysis module 330 assumes that the hyperspectral observation value Y and the calculated band ratio X are in a linear relationship, and the hyperspectral observation values at the multiple points ( And generating a regression equation (Y=aX+b) by calculating a and b of the regression equation (Y=aX+b) using Y) and the calculated band ratio (X). It provides a method of utilizing hyperspectral images using rain.
