Problems solved by technology

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

Abstract

An embodiment of the invention provides a water color parameter inversion device and method for a near-shore estuary. According to the embodiment, a water bio-optical model is established through acquisition of remote sensing reflectance and water color parameters of the near-shore estuary, and the water bio-optical model is subjected to parameter optimization according to the acquired remote sensing reflectance and water color parameters; a near-shore estuary water color parameter inversion model of the water bio-optical model is established on the basis of a parameter optimization result of the water bio-optical model, water color parameter inversion of the near-shore estuary is realized, and an inversion result is obtained. With the adoption of the embodiment, the inversion precision of the water color parameters of the near-shore estuary can be improved.

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...
