Abstract

The embodiment of the invention provides a chlorophyll remote sensing inversion device and a chlorophyll remote sensing inversion method. Based on sensitivity analysis of a spectral characteristic of chlorophyll a, an improved chlorophyll a inversion model is formed, and influence of complex optical property of a nearshore water body on the chlorophyll a is integrally considered; meanwhile, an HICO high spectral image is pre-processed to obtain an image mean value spectrum of an experimental sample region. The constructed chlorophyll a inversion mode is applied to the pre-processed image for chlorophyll a inversion. According to the embodiment of the invention, the inversion precision of the chlorophyll a is hugely increased.

Description

technical field [0001] The invention relates to the field of water color remote sensing inversion, in particular to a chlorophyll remote sensing inversion device and method for complex spectral conditions in coastal estuaries. Background technique [0002] Chlorophyll-a is an important index to evaluate the nutritional status and barrenness of water bodies. The degree of eutrophication of water bodies can be judged by measuring the concentration of chlorophyll-a. However, the inversion of chlorophyll-a in coastal waters is affected by the complex optical characteristics of water bodies, and the inversion accuracy is low. Contents of the invention [0003] In view of the above, an embodiment of the present invention provides a chlorophyll remote sensing inversion device, which is applied to water color parameter inversion equipment. The inversion device includes: [0004] The remote sensing image acquisition module is used to acquire the hyperspectral remote sensing image...
