Embodiment 1

[0036] figure 1 It is a flow chart of a method for spraying pesticides by drone provided in Embodiment 1 of the present invention, comprising the following steps:

[0037] S1. Collect images of crops in the operation area, and compare them with images of crops pre-stored in database 1 to determine the types of crops.

[0038] Specifically, the images of the crops in the operation area are collected by the UAV image collection module.

[0039] S2. Collect images of crops in the operation area, and compare them with the images of pests prestored in database 2 to determine the types of pests.

[0040] Specifically, the databases 1 and 2 are respectively used to store images of crops of different types of crops and types of pests.

[0041] S3. Determine the type of pesticide to be sprayed according to the type of crops and the type of pests.

[0042] Specifically, the types of crops include all crops such as rice, wheat, corn, cotton, rape, etc., and the types of pests include ...

Embodiment 2

[0046] figure 2 It is a flow chart of a method for spraying pesticides by drone provided in Embodiment 2 of the present invention, comprising the following steps:

[0047] S401. Collect images of crops with slight pest damage, moderate pest damage and severe pest damage respectively, perform preprocessing on the images, extract image feature values ​​and save them as image feature value databases, namely database three;

[0048] S402. Collect images of crops in the operation area, preprocess the images, extract image feature values ​​and compare them with image feature values ​​in the pre-stored database;

[0049] S403, judging the similarity between the feature value of the crop image in the operation area and the feature value of the image in the database;

[0050] S404. If the similarity of the image feature value is close to 0, it means that there is no or very little pests, and no pesticide spraying is performed on it; if the similarity does not reach the predetermined ...

Embodiment 3

[0055] image 3 It is a structural block diagram of an unmanned aerial vehicle pesticide spraying system provided in Embodiment 3 of the present invention. The system includes an unmanned aerial vehicle and a ground station, and the unmanned aerial vehicle includes a pesticide sprayer, a water tank, a dispensing box, a pesticide box, an image acquisition module, a processor, a weight sensor, a wireless communication module 1, and image data Transceiver one, the ground station includes an image data transceiver two, an image recognition module, three image databases, a controller, an alarm module and a wireless communication module two, and the wireless communication module is used between the UAV and the ground station connect.

[0056] In this embodiment, the image acquisition module is connected to an image data transceiver for acquiring images of crops;

[0057] In this embodiment, the water tank and the pesticide box are respectively connected to the dispensing box, and ...

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and provides an unmanned aerial vehicle pesticide spraying method and system. The unmanned aerial vehicle pesticide spraying method comprises the following steps: (1) acquiring crop images of a working area, and comparing the crop images with crop images stored in a databank I in advance so as to confirm types of crops; (2) acquiring crop images of the working area, and comparing the crop images with insect images stored in a databank II in advance so as to confirm types of insects; (3) confirming types of insecticides to be sprayed according to the types of the crops and the types of the insects; (4) confirming the serious degree of crop insects, preparing insecticides of proper concentration according to the types of the insecticides and the serious degree of the crop insects, and spraying the insecticides. As the insecticides are automatically specifically sprayed according to the types of the crops and the crop insects, the insecticide spraying effects and the utilization rates of the insecticides can be improved, insecticide waste can be avoided, the cost can be reduced, and the intelligence and automation levels of the insecticide spraying process are increased.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a pesticide spraying method and system for drones. Background technique [0002] my country is a large agricultural country, and the development of efficient and safe modern ecological agriculture is an important goal of sustainable agricultural development and modernization. In the current crop production process, it is vulnerable to various insect pests, which seriously affects the crop yield. In order to effectively control pest disasters, protect the healthy growth of crops, and increase yields, it is necessary to spray pesticides on crops to kill pests. Traditional agricultural plant protection is dominated by manual and semi-mechanized operations. Operators spray with experience, which is labor-intensive, wastes pesticides, and direct contact with pesticides will cause great harm to the workers. With the development of drone technology, the use of unmanned Spraying pestici...
