The invention discloses an integrated method and device for unmanned aerial vehicle remote sensing pesticide spraying based on visible light thermal infrared image fusion, which belongs to the technical field of agricultural plant protection pesticide spraying and includes the following steps: 1) setting the flight route; 2) using a visible light camera Collect visible light images and thermal infrared images of farmland crops with thermal infrared cameras respectively, and transmit the images to the processor; 3) Register and fuse the visible light images and thermal infrared images in sequence, and extract the lesion outline in the fused images and color feature information; 4) establish a crop disease category discrimination model according to the lesion outline and color feature information in the fusion image; 5) repeat steps 1) to 3), and perform crop processing on the extracted fusion image according to the crop disease category discrimination model. Discrimination of disease types; 6) Control the opening valves of different medicine boxes according to the types of crop diseases. The fusion of thermal infrared images and visible light images can contain more image information and improve the accuracy of disease discrimination.
Description
technical field [0001] The invention relates to the technical field of pesticide spraying for agricultural plant protection, in particular to an integrated method and device for drone remote sensing pesticide spraying based on visible light thermal infrared image fusion. Background technique [0002] Countries around the world have different application levels of plant protection drones, but in general, agricultural aviation technology is an important part of national agricultural production, and the proportion of application in agricultural production is increasing. With the rapid development of science and technology, the use of drones has become more and more widespread, and agricultural-related infrastructure has also been continuously improved. The spraying drone adopts intelligent control and uses the spraying drone to replace manual traditional spraying equipment. Spraying pesticides greatly reduces the demand for labor in agricultural production. Small UAV spraying ...
