Crop irrigation system based on computer vision

Abstract

The invention relates to the image processing technology and the water-saving irrigation field and discloses a crop irrigation method based on the computer vision. The crop irrigation method adopts the technology of nondestructive crop water lack detection based on the computer vision, in addition, a crop growth data model is combined, finally, the automatic judgment is made, and an electromagnetic valve is controlled for completing the crop irrigation. According to a system, the steps such as crop image obtaining, color space conversion, image dividing and characteristic parameter extractionare firstly carried out, then, the characteristic parameter calculation is carried out through being combined with the crop growth data model, the judgment is completed through a genetic neural network, and finally, a single chip microcomputer is controlled to drive the electromagnetic valve for completing the crop irrigation according to the judgment results. The system provided by the inventioncan obtain the water demanding information of crops in time and can realize the in-time and accurate irrigation, and the water resource utilization rate is perfectly improved. The system has good practicability and can be applied to crop planting regions such as greenhouses, farmlands and nursery gardens.

Description

technical field [0001] The invention relates to the field of computer vision and processing technology and water-saving irrigation, in particular to a water-saving irrigation method based on computer vision detection of crop shape and color change, judgment and control. Background technique [0002] Computer vision is a science and technology that uses computer technology to simulate the human visual mechanism to identify and classify objects in the obtained visual images. It is an interdisciplinary subject integrating image acquisition, image processing and recognition, pattern recognition and other disciplines. With the continuous development of computer software and hardware technology, computer vision has gradually entered practical applications. [0003] With the development of science and technology, agricultural production is also rapidly changing the traditional farming mode, modern science and industrial technology has gradually penetrated into agricultural product...

Problems solved by technology

However, LVDT is mainly used in industrial metrology in the field of machinery manufacturing. Although the measurement resolution and accuracy can meet the requirements, due to the rigidity of the contact point, it will affect the growth of crops, and it cannot well meet the actual requirements for crop measurement.

Some scholars also use sensors or micrometers to measure the fruits or leaves of crops, but these methods require contact operations with the fruits or leaves of crops, and measure the slight changes in plant organs through sensors or mechanical devices to obtain water demand information to control irrigation. These methods are time-consuming and labor-intensive due to the need for on-site operations, and because they are contact measurements, they also have a certain impact on the growth of crops

At present, some foreign scholars are also engaged in the use of short-range infrared remote sensing images to detect the water demand of crops. This technology is very expensive and has not yet reached the level of practical application.
