AI Technical Summary
The prior art is difficult to effectively obtain the vertical distribution information of chlorophyll a concentration in water bodies, and the detection accuracy and spatial coverage are limited.
The photon data are divided into water surface photons and underwater photons through segmented statistical models. The refraction correction model is constructed using wave fitting reconstruction, and nonlinear correction is performed in combination with satellite image data to establish the initial and final underwater concentration models to obtain the three-dimensional chlorophyll a concentration of regional water bodies.
It improves the accuracy and reliability of chlorophyll a concentration detection, can more comprehensively reflect the vertical and horizontal distribution of chlorophyll a in water body, and provides a more accurate and comprehensive data basis.
