Catalpa bungei leaf photosynthetic pigment quantitative inversion method based on hyperspectral reflectivity

The invention discloses a catalpa bungei leaf photosynthetic pigment quantitative inversion method based on hyperspectral reflectivity, and the method comprises the steps: collecting the spectral reflectivity information corresponding to a plurality of catalpa bungei leaves through a hyperspectral spectrometer, and enabling the spectral reflectivity information to be used for indicating the reflectivity of light of different wavelengths of a spectrum on the catalpa bungei leaves; measuring photosynthetic pigment content information of the catalpa bungei leaves; constructing a sample set according to the spectral reflectivity information and the photosynthetic pigment content information respectively corresponding to the catalpa bungei leaves; determining an independent variable corresponding to the spectral reflectivity information according to the sample set, and determining an inversion model corresponding to the independent variable; and determining the photosynthetic pigment content information of the tar
