Agricultural greenhouse breakage detection device based on machine vision technology

Abstract

The invention provides an agricultural greenhouse breakage detection device based on a machine vision technology, and belongs to the field of non-destructive detecting. The agricultural greenhouse breakage detection device is characterized in that the machine vision technology of a high-flexibility image taking device is adopted to real-timely monitor the breakage situation of an agricultural greenhouse. According to the agricultural greenhouse breakage detection device, through the image taking device, the extracted greenhouse surface plastic film features are converted into image and digitalsignals, the greenhouse surface plastic film state is detected according to the system judgment result, and when abnormity is detected, an alarm signal is sent out so as to avoid the situation that the greenhouse is affected by the external severe weather and other factors and consequently, the crop loss is caused. According to the agricultural greenhouse breakage detection device, the agricultural greenhouse state can be detected effectively in real time, the structure is simple, and human-machine interaction operation is easy.

Description

technical field [0001] The invention relates to a damage detection device for agricultural greenhouses based on machine vision technology, in particular to a device for detecting damage to plastic insulation films on the surface of agricultural greenhouses using machine vision technology with high flexibility and intelligent image capture devices, belonging to field of non-destructive testing. Background technique [0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in the thermal insulation covering of the surface of agricultural greenhouses, and in this way, the positive effects of early maturity, increased production and seasonal sales of crops have been obtained. At present, agricultural greenhouses have been used in various industries such as potted and cut flower cultivation, fruit tree production, forestry production, and aquaculture. However, while agricultural greenhouse technology brings new pr...

Problems solved by technology

In practical application, due to the long-term operation of the greenhouse in a high-temperature and high-humidity environment, the plastic insulation film covered on the surface is prone to aging and damage

At the same time, under the condition of low temperature at night, grass quilt and grass thatch have good thermal insulation performance and are indispensable as nighttime thermal insulation materials. Although both are made of straw textile, they are easily scratched during the process of laying and rolling. plastic insulation film

After the insulation film is damaged, the crops will be sick and reduce production due to temperature or pests, or the structure of the agricultural greenhouse will be dislocated due to strong winter winds, resulting in large-scale accidents such as deformation, collapse, and "running of the shed", endangering farmers' property and personal safety.

[0003] For the real-time detection of the above situations, the methods that have been adopted now include thermal detection, sensor detection, etc., but these methods have many problems such as detection accuracy, real-time performance, and poor adaptability under harsh conditions, especially in some devices. It is very difficult to realize the problem of affecting the structural stability of the agricultural greenhouse itself, and even destroying the structure of the agricultural greenhouse itself. Therefore, a device that can adapt to harsh conditions and can accurately detect the damage of the plastic insulation film covering the surface of the agricultural greenhouse in real time is needed.
