Problems solved by technology
[0005] 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
[0017] 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.
[0018] 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.
[0019] Grape is one of the agricultural and forestry products that are more sensitive to ov...

The invention relates to an image processing-based grape water stress detection method. The method includes the following steps: (1) an image processing-based grape water stress detection device is provided to detect the water stress value of a grape plant, the detection device comprises a humidity sensor, an image acquisition unit, an image processor and an AT89C51 singlechip, the humidity sensor is used for detecting the soil humidity of soil where the grape plant are located, the image acquisition unit is used for photographing a grape leaf of the grape plant to obtain a grape leaf image, the image processor is connected with the image acquisition unit to execute image processing on the grape leaf image, and the singlechip is respectively connected with the humidity sensor and the image processor, and determines the water stress value of the grape plant on the basis of the soil humidity and an image processing result; (2) the device is used for carrying out detection.
Description
[0001] This invention is a divisional application of a patent with the application number 201510026928.1, the application date is January 19, 2015, and the invention title is "A Method for Grape Water Stress Detection Based on Image Processing". technical field [0002] 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 [0003] 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 s...
