Plant protection unmanned aerial vehicle pesticide accurate spraying system and spraying method

Abstract

The invention discloses a plant protection unmanned aerial vehicle pesticide accurate spraying system and a spraying method. A sub machine vision camera device and an image recognition controller are arranged on a plant protection unmanned aerial vehicle; the image recognition controller classifies priori calibrated images according to insect pest severity level classification in an area and then readjusts the spraying quantity of a spraying device according to real-time collected image classification information so as to realize accurate spraying of pesticide. Disease and insect pest graph characteristics of field crops are obvious; before pesticide accurate spraying of the plant protection unmanned aerial vehicle, the unmanned aerial vehicle can be adopted to sample diseases and insect pests in a spraying area and manually calibrate samples into priori knowledge; and the unmanned aerial vehicle can perform classifying operation according to a planned spraying route. According to the plant protection unmanned aerial vehicle pesticide accurate spraying system, the pesticide spraying quantity of a spraying control method can be automatically adjusted according to the flying height and the flying speed of the unmanned aerial vehicle; and by using an image recognition graded spraying strategy, the pesticide spraying quantity can be greatly reduced.

Description

technical field [0001] The invention relates to a plant protection drone and its application, in particular to a plant protection drone pesticide precision spraying system and spraying method. Background technique [0002] When spraying pesticides by plant protection drones, uniform spraying is often used for operations. The control of spraying pesticides is mainly based on open-loop control, that is, continuous and uninterrupted uniform spraying according to the planned route, and the spraying method is single. The spraying method relies on manual operation experience, and it cannot be sprayed according to the actual pest damage status of the field crops. If the spraying effect is better, excessive spraying is often used, which will easily cause waste of liquid medicine and environmental pollution. Contents of the invention [0003] Purpose of the invention: The invention discloses a precise spraying system and spraying method of plant protection UAV pesticides. The spray...
