Embodiment Construction

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.

[0051] figure 1 It is a schematic flow chart of a method for detecting the water content of plant leaves provided by this application, and the method can be executed by devices with processing functions such as computers and servers, such as figure 1 As shown, the method includes:

[0052] S110. Obtain hyperspectral data of leaves of the plant to be measured.

[0053] Since the water content of plant leaves has a good indicator effect on the growth and development of plants and the soil moisture in the plow layer, it is of great significance to st...

Abstract

The invention provides a plant leaf moisture content detecting method and device, and relates to the technical field of detection. The plant leaf moisture content detecting method comprises the stepsof: obtaining hyperspectral data of a plant leaf to be detected; and processing the hyperspectral data of the plant leaf to be detected according to a preset diagnosis model to obtain a diagnosis result output by the diagnosis model, wherein the diagnosis model comprises a preset corresponding relationship between the hyperspectral data of the plant leaves and moisture contents, and the diagnosisresult is the moisture content of the plant leaf to be detected. According to the plant leaf moisture content detecting method and device provided by the invention, the measured hyperspectral data ofthe plant leaf are input to the established diagnosis model, so that the moisture content of the plant leaf can be directly output, the output result is accurate, and the timeliness is improved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method and device for detecting the water content of plant leaves. Background technique [0002] Water is a material element necessary for the growth and development of plant leaves, and is the main medium for the transportation of mineral nutrients and the physiological and biochemical reactions of chloroplasts. The water content of the internal tissues of plant leaves has a good indicator effect on the soil moisture in the plow layer, which can reflect the impact of drought stress on plant growth and development, and within a certain limit, the reduction of water content in plant leaves helps to increase the protein content of plant grains. Improve the quality level of plant grains. Therefore, how to detect the water content of plant leaves in real time and accurately is an important issue. [0003] In the prior art, multiple leaf samples are collected, each leaf sample i...
