Abstract

The invention discloses a water chlorophyll concentration inversion method and device based on hyperspectral remote sensing. The method comprises the steps that a target sampling hyperspectral remotesensing image corresponding to a target area is acquired; obtaining chlorophyll concentration measured values of a plurality of sampling stations in the target area; acquiring a pixel spectral curve corresponding to each sampling site based on the target sampling hyperspectral remote sensing image; obtaining a plurality of first pixel spectral curves from the pixel spectral curves; acquiring characteristic waveband reflectivity corresponding to each first pixel spectral curve based on each first pixel spectral curve; performing model training based on the characteristic waveband reflectivity corresponding to each first pixel spectral curve and the chlorophyll concentration measured value corresponding to each first pixel spectral curve to obtain an inversion model of chlorophyll concentration; and performing chlorophyll concentration inversion on the hyperspectral remote sensing image of the target area based on a chlorophyll concentration inversion model.

Description

technical field [0001] The invention relates to the technical field of quantitative remote sensing of water environment, in particular to a method and device for retrieving chlorophyll concentration of water body based on hyperspectral remote sensing. Background technique [0002] In view of the fact that there are many inland lakes, which are greatly affected by industrial pollution and domestic pollution, resulting in a large number of algae blooms in the lakes and the eutrophication of the lakes is becoming more and more serious. At present, the commonly used methods for water quality monitoring include semi-empirical methods, semi-analytical methods, The artificial intelligence model mainly uses remote sensing data sources such as SeaWIFS, MODIS, Landsat TM, SPOT, ERS-2, etc. The semi-empirical method is to consider the influence of the spectral characteristics of water quality parameters on the concentration of water quality parameters, and use the characteristic band o...
