Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] The inventors of the present application found that the current existing leaf chlorophyll content inversion method based on the chlorophyll vegetation index uses the information of the red band, red edge band and near-infrared band to calculate the chlorophyll vegetation index, although these bands can reflect the chlorophyll content. , but these bands are also affected by the leaf area index. For example, the reflectivity of the near-infrared band is gr...

Abstract

The embodiment of the invention discloses a leaf chlorophyll content inversion method and device, electronic equipment and a storage medium, and the method comprises the steps: calculating the chlorophyll vegetation index of a target pixel through the reflectivity of a near-infrared band, the reflectivity of a red band and the reflectivity of a blue band of the target pixel in a remote sensing image; and calculating the leaf chlorophyll content of the target pixel according to the chlorophyll vegetation index. The sensitivity of the chlorophyll vegetation index constructed by the reflectivityof the near-infrared band, the reflectivity of the red edge band and the reflectivity of the blue band to vegetation canopy information and background information is lower than the sensitivity of thechlorophyll vegetation index to leaf chlorophyll content; therefore, influence of vegetation canopy information and background information on leaf chlorophyll content calculation is reduced, and the calculation precision of the leaf chlorophyll content inversion method based on the chlorophyll vegetation index is further improved.

Description

technical field [0001] The present application relates to the technical field of remote sensing, and more specifically, relates to a leaf chlorophyll content inversion method, device, electronic equipment and storage medium. Background technique [0002] The chlorophyll content of leaves reflects the important information of plant photosynthetic ability and developmental stage, and is an important index to measure plant physiological conditions, productivity and stress. The current leaf chlorophyll content inversion methods are mainly divided into two types: the inversion method based on the chlorophyll vegetation index and the inversion method based on the physical model. The relational calculation of leaf chlorophyll content is widely used because of its simple thinking and high calculation efficiency. However, the current inversion method based on chlorophyll vegetation index will be affected by vegetation canopy information such as leaf area index, leaf inclination angl...
