Abstract

The embodiment of the present invention provides a chlorophyll remote sensing retrieval device and method. The embodiment of the present invention forms an improved chlorophyll-a inversion model based on the sensitivity analysis of the spectral characteristics of chlorophyll-a, and comprehensively considers the influence of the complex optical characteristics of nearshore water bodies on chlorophyll-a; at the same time, preprocessing is performed on the HICO hyperspectral image , to obtain the image mean spectrum of the experimental sample area, and apply the constructed chlorophyll a inversion model to the preprocessed image for chlorophyll a inversion. The embodiments of the present invention greatly improve the accuracy of chlorophyll a inversion.

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...
