However, it is difficult to directly measure the inherent optical characteristic parameters of near-shore estuaries, which makes it difficult to apply bio-optical models in near-shore estuaries.
The water body bio-optical model also assumes that the combination of the inherent optical properties of each component of the water body is linear, but in fact the relationship between the components of the highly turbid near-shore estuary water body is a complex nonlinear relationship, and this assumption is directly adopted May lead to failure of water color parameter inversion

The embodiment of the present invention provides a near-shore estuary water color parameter inversion device. The embodiment of the present invention establishes a water bio-optical model by acquiring the remote sensing reflectance and water color parameters of the near-shore estuary, and optimizes the parameters of the water bio-optical model according to the obtained remote sensing reflectance and water color parameters. Then, a water color parameter inversion model of the near-shore estuary of the bio-optical model is established based on the parameter optimization results of the above-mentioned water bio-optical model, so as to realize the inversion of the water color parameters of the near-shore estuary, and obtain the inversion result. The embodiments of the present invention can improve the inversion accuracy of water color parameters of near-shore estuaries.
Description
technical field [0001] The invention relates to the field of water color optical remote sensing inversion, in particular to a water color parameter inversion device and method for near-shore estuaries based on the correction of the nonlinear effect of the water component spectrum. Background technique [0002] At present, the inversion model based on bio-optics can calculate the concentration of the three elements of water color (CDOM, suspended solids, and chlorophyll a). The bio-optical model has good physical meaning and certain universality, so it has been widely concerned and used by more and more scholars of water color remote sensing. However, it is difficult to directly measure the inherent optical characteristic parameters of near-shore estuaries, which makes it difficult to apply bio-optical models to near-shore estuaries. The water body bio-optical model also assumes that the combination of the inherent optical properties of each component of the water body is li...
