Greenhouse intelligent plant protection device and plant protection method based on crop phenotypic machine vision discrimination

Abstract

The invention provides a greenhouse intelligent plant protection device based on crop phenotypic machine vision discrimination. The device comprises a moving device, a dispensing device, a pesticide spraying device, a vision device, and a central control unit; the vision device comprises a multispectral camera and a close-range camera; the pesticide spraying device comprises a first pesticide spraying rod, a second pesticide spraying rod, and a plurality of rotor wings; and the first pesticide spraying rod and the second pesticide spraying rod are provided with a plurality of spray heads capable of independently controlling the spraying amount. According to the greenhouse intelligent plant protection device based on crop phenotypic machine vision discrimination, crop phenotypes are monitored through the vision device to judge disease and insect pest types and degrees, early warning is conducted, an administrator is assisted in accurately selecting pesticide in time and automatically dispensing the pesticide, the central control unit plans a navigation route, and the pesticide spraying amount of each spray head is adjusted in real time according to the disease and insect pest degrees and positions, so that the purpose of combining disease treatment and prevention is achieved, precise pesticide application, water and fertilizer saving and green development are achieved, the pesticide poisoning phenomenon of operators can be effectively avoided, and the safety and the precision of greenhouse plant protection operation are promoted.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to a greenhouse intelligent plant protection device and a plant protection method based on machine vision discrimination of crop phenotypes. Background technique [0002] As a large agricultural country, China has 1.8 billion mu of basic farmland, which requires a large number of agricultural plant protection operations every year. In my country, 100,000 people are poisoned by pesticides every year, and the fatality rate is about 20%. Compared with field operations, the greenhouse environment is relatively airtight and the air circulation is poor. The harmful effects of pesticide exposure on the operator's body during plant protection operations are more serious. Moreover, due to the backwardness of traditional pesticide application technology and concept of pesticide application, problems such as "dripping medicine", uneven spraying, pesticide residues and envi...

Problems solved by technology

Compared with field operations, the greenhouse environment is relatively airtight and the air circulation is poor. The harmful effects of pesticide exposure on the operator's body during plant protection operations are more serious.

Moreover, due to the backwardness of traditional pesticide application technology and concept of pesticide application, problems such as "dripping medicine", uneven spraying, pesticide residues and environmental pollution

[0003] In recent years, with the advancement of agricultural mechanization and agricultural greening, my country has developed and promoted human plant protection machinery such as knapsack sprayers and stretcher sprayers, small power plant protection machinery suitable for standardized farmland, and tractor supporting plant protection machinery. Problems such as uneven spraying and low spraying efficiency
