Problems solved by technology
[0004] In the prior art, the water stress of grapes is detected by instruments such as pressure balls or leaf porometers, which directly act on the grapes. This detection method is time-consuming and inefficient, and requires direct contact with the grapes, which is easy to form due to contact. The amount of detection error caused by

Embodiment Construction
[0016] The implementation of the image processing-based grape water stress detection device of the present invention will be described in detail below with reference to the accompanying drawings.
[0017] Water is the lifeblood of the development of agriculture and forestry, and irrigation is the guarantee for the development of agriculture and forestry. Various countries and regions are vigorously developing local farmland water conservancy and irrigation systems. Recently, on the one hand, agriculture and forestry are facing the challenges of severe water shortage and drought; on the other hand, there are lagging development of farmland irrigation facilities and irrigation technology, resulting in excessive waste of man-made water resources and energy, and excessive irrigation of agricultural and forestry products. The land restricts the development of agriculture to a higher level.
[0018] Grape is one of the agricultural and forestry products that are more sensitive to ov...

The invention relates to a grape moisture stress detection method based on image processing. The method comprises the following steps: (1) grape moisture stress detection equipment based on the image processing is provided for detecting a moisture stress value of one grape vine, wherein the detection equipment comprises a humidity sensor, an image acquisition device, an image processor and an AT89C51 single chip microcomputer; the humidity sensor is used for detecting soil humidity of soil of grapes; the image acquisition device is used for photographing one grape leaf of the grape vine to obtain a grape leaf image; the image processor is connected with the image acquisition device and is used for carrying out image processing on the grape leaf image; the single chip microcomputer is connected with the humidity sensor and the image processor respectively; the moisture stress value of the grape vine is determined based on the soil humidity and an image processing result; and (2) the detection is carried out by using the equipment.
Description
technical field [0001] The invention relates to the field of agriculture and forestry irrigation, in particular to a method for detecting grape water stress based on image processing. Background technique [0002] In the process of agricultural and forestry production, the moisture content of the soil is related to the output of related products. Since agricultural and forestry products generally contain a large amount of water, for example, vegetables contain 90%-95% water. Water transports nutrients for plants; water keeps plant branches and leaves in a graceful shape; water participates in photosynthesis to produce organic matter; water evaporation keeps plants at a stable temperature and prevents them from being burned by the sun. Agricultural and forestry products not only have high water content, but also consume water throughout the growth process. For example, 1 kilogram of corn is irrigated with 368 kilograms of water; similarly, wheat is 513 kilograms of water, c...
