Abstract

The invention discloses a method for representing soil components by using an image. The method comprises the following steps: acquiring geographical coordinate information of a target plot; establishing a land parcel image corresponding to the hyperspectral image; recombining the plot image to the hyperspectral image to form a temporary hyperspectral image on the hyperspectral image; correcting the temporary hyperspectral images in groups according to land parcel information and acquisition point detection results; and recombining the corrected temporary hyperspectral image according to the land parcel information to form a corrected hyperspectral image. According to the invention, the plot image is recombined to the hyperspectral image to form the temporary hyperspectral image on the hyperspectral image, and the temporary hyperspectral image is corrected in groups according to the plot information and the collection point detection result, so that the corrected hyperspectral image can be finally formed, therefore, the purpose of correcting the hyperspectral image by taking the plot as the center is achieved.

Description

technical field

[0001] The invention relates to the technical field of soil components, in particular to a method for representing soil components with images. Background technique

[0002] Soil health is a key production factor in agriculture. Changes in soil composition directly affect crop yields and ecological environment, especially water environment and air quality. Knowledge of soil composition is key to managing, maintaining and improving soil fertility and agricultural productivity. Effective detection of soil composition and grasp of soil change trends are necessary means for the protection and supervision of cultivated land. At present, the methods of soil testing are mostly based on the collection of sample points, laboratory testing by chemical methods or physical and chemical methods, and then a test report is issued. The change of soil composition can only be analyzed through the long-term monitoring of fixed collection points and the analysis of the change...
