Embodiment Construction

[0035] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] The crop canopy reflectance signal is not only affected by intrinsic factors such as biochemical parameters (pigment content, moisture content, etc.) and biophysical parameters (leaf tilt angle, LAI, etc.), but also by atmospheric effects, soil background, illumination geometry, and imaging geometry and other external factors. In order to reduce the impact of non-photosynthetic factor...

Abstract

The invention provides a chlorophyll content remote sensing inversion method and device, electronic equipment, a medium and a product. The method comprises the following steps: acquiring spectral information of a to-be-detected sample; calculating a chlorophyll content sensitive red-edge trigonometric vegetation index RETVI of the to-be-detected sample according to the reflectivity at the multiple wave bands in the spectral information of the to-be-detected sample; according to the RETVI of the to-be-detected sample and the linear relation between the RETVI and the chlorophyll content, the chlorophyll content of the to-be-detected sample is obtained through inversion. The method has the best performance in adaptability tests of multiple scenes of different spectral data types, different vegetation types, different crop growth periods, different vegetation coverage degrees and the like. Meanwhile, the method not only provides a reliable and powerful tool for wide-range remote sensing application, but also provides a brand-new thought for construction of a new index.

Description

technical field [0001] The invention relates to the technical field of remote sensing, in particular to a remote sensing inversion method, device, electronic equipment, medium and product for chlorophyll content. Background technique [0002] Chlorophyll content is a very sensitive indicator that comprehensively reflects the external environmental stress of crops, the strength of photosynthesis and the degree of metabolism. It not only reflects the growth status of crops, but also is an important substance for material and energy exchange between crops and the outside world. Base. Remote sensing inversion is an important approach to earth observation, which usually uses the electromagnetic wave information of macroscopic regional objects obtained by space remote sensing technology as the data source. [0003] In remote sensing, the chlorophyll content per unit leaf area of ​​canopy (CCC) is an important indicator to measure the growth status of plants. Previous studies hav...
