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...

Abstract

The invention relates to image processing based grape moisture stress detection equipment comprising a humidity sensor, an image acquisition device, an image processor and an AT89C51 singlechip, wherein the humidity sensor is used for detecting the soil humidity of the soil in which a grape is planted; the image acquisition device is used for shooting a grape leaf of the grape so as to acquire a grape leaf image; the image processor is connected with the image acquisition device and is used for performing image processing on the grape leaf image; and the singlechip is connected with the humidity sensor and the image processor respectively and is used for determining a water stress value of the grape on the basis of the soil humidity and the processing result of the image. By using the equipment provided by the invention, the water stress value of the grape can be accurately detected, thereby providing valuable reference data for irrigation of grapes.

Description

technical field [0001] The invention relates to the field of agriculture and forestry irrigation, in particular to a grape water stress detection device 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, cotto...
