Problems solved by technology

[0005] The use of drones for pesticide spraying has gradually gained more and more attention. However, when the existing unmanned aircraft are spraying pesticides on a large area, they often point out areas with crop growth problems, and then carry out large-scale pesticide spraying. The problems that are likely to arise are: 1) Non-sick or problem-free crops are still sprayed with pesticides, causing pesticide waste and polluting the environment; Can not achieve good spraying effect when spraying pesticides

Embodiment 1

[0048] This example provides a method for intelligent identification and precise spraying of pesticides by drones. The flow chart is as follows figure 1 As shown, it specifically includes the following steps.

[0049] S100: pre-dividing the crop area into multiple sub-intervals for collecting information and spraying respectively.

[0050] To achieve the purpose of precise spraying of pesticides on large-area crops, it is necessary to divide the large-area crops into several sub-intervals for collecting information and spraying them separately, and then manage the crops in each sub-interval.

[0051] S200: Control the reconnaissance UAV to collect images of crops in each sub-interval of the required area, and feed back to the control center.

[0052]After the crops are sprayed with pesticides, there is no need to continue spraying the pesticides for a period of time, that is, there is no need to collect images of the crops in the area. Therefore, the image of the crops in eac...

Embodiment 2

[0063] Based on Embodiment 1, this example provides a system for intelligent identification and precise spraying of pesticides by drones, the principle diagram of which is as follows figure 2 As shown, it includes: a control center 1, a scouting drone 2 and a spraying drone 3, and the scouting drone 2 and the spraying drone 3 are respectively connected to the control center 1 with wireless signals.

[0064] The control center 1 divides the pre-stored crop area into multiple sub-sections, and the control center 1 controls the reconnaissance drone 2 to collect crop images in each sub-section, and the reconnaissance drone 2 feeds back the crop images to the control center 1; the control center 1 It is also used to automatically compare the collected crop images with the pre-stored crop images or pest data of diseases and insect pests to identify whether there are pests and diseases in the collected sub-intervals. If there are, the spraying drone 3 is controlled to spray the corre...

Abstract

The invention relates to a method and system for intelligent identification and accurate pesticides spraying using unmanned aerial vehicles. The method comprises the following steps: dividing a crop area into a plurality of subregions; controlling an unmanned surveillance aerial vehicle to acquire crop images in each subregion and feeding the images to a control center; automatically comparing the acquired crop images with prestored images of crops subjected to pest and disease damages to identify the presence of pest and disease damages in each subregion, and if pest and disease damages exist, controlling an unmanned spraying aerial vehicle to accurately spray corresponding proportions or corresponding types of pesticides to the corresponding subregions. For the method, pesticides are sprayed only to subregions with crops subjected to pest and disease damages instead of large area pesticide spraying in a full range, thus reducing the waste of pesticides and protecting ecological environment; in addition, corresponding proportions or corresponding types of pesticides are sprayed according to specific circumstances of pest and disease damages, the same ratio of pesticides is not adopted for different pest and disease damages that the crops are subjected to, so that effective spraying treatment effect can be achieved for the crops subjected to different pest and disease damages.

Description

technical field [0001] The invention relates to the technical field of crops, in particular to a method and system for intelligent identification and precise spraying of pesticides by an unmanned aerial vehicle. Background technique [0002] With the development of science and technology, the traditional agricultural production mode is gradually replaced by mechanization and informatization. The use of drones for low-altitude operations has the characteristics of flexible use, small size, and low cost, which can greatly improve the efficiency of agricultural and forestry vegetation flying operations. efficiency and precision. At present, the domestic unmanned light and small aircraft industry for agricultural use is in the research and preliminary trial stage, and my country's agricultural aviation technology is still in its infancy. [0003] Drones could theoretically provide detailed information on three fronts in agriculture. First, viewing crops from the air can reveal...
