Method and device for automatically identifying crop diseases by plant protection unmanned aerial vehicle

Abstract

The invention discloses a method for automatically identifying crop diseases by a plant protection unmanned aerial vehicle. The method comprises the following steps that: obtaining image information shot by the unmanned aerial vehicle on a preset proceeding route, and comparing the image information with a preset database; when the comparison result of the image information is a disease picture, reducing the flight speed of the unmanned aerial vehicle, and increasing the pesticide spraying amount of the unmanned aerial vehicle; and obtaining position information when the unmanned aerial vehicle shots the image information, and according to the position information, generating prompt information. The invention also relates to a device for automatically identifying crop diseases by the plantprotection unmanned aerial vehicle. The unmanned aerial vehicle is controlled to reduce the flight speed and increase the pesticide spraying amount, and pesticide spraying intensity is enlarged for crops on the positions of plant diseases and insect pests so as to reduce plant diseases and insect pests.

Description

technical field [0001] The invention relates to the field of crop plant protection by drones, in particular to a method and device for automatically identifying crop diseases by a plant protection drone. Background technique [0002] With the rapid development of drone technology, drones can be applied to more and more industries, and compared with artificial, drones have more and more advantages, such as the ability to go to some dangerous places and the range of activities Wide and so on. In the field of crop plant protection, using drones instead of manual plant protection work has the advantages of high efficiency, speed, and manpower saving. However, plant protection drones are still unable to do autonomous work at present, and are still manually controlled remotely in many cases. This method not only It is inconvenient to operate, and it is impossible to achieve large-scale and accurate standardized operations. Although the UAV plant protection system in Chinese pate...

In the field of crop plant protection, using drones instead of manual plant protection work has the advantages of high efficiency, speed, and manpower saving. However, plant protection drones are still unable to do autonomous work at present, and are still manually controlled remotely in many cases. This method not only It is inconvenient to operate, and it is impossible to achieve large-scale and accurate standardized operations

Although the UAV plant protection system in Chinese patent CN201620704145.4 can realize the intelligent operation of data collection, analysis and response in the process of plant protection, it does not have a targeted judgment method and countermeasures for pests and diseases, and the judgment of pests and diseases is not accurate enough , the actual effect is not good
