Title:
ドローンを使用した肥料散布方法
Document Type and Number:
Japanese Patent JP6906959
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pesticide spraying method using a drone in which chemicals such as pesticide can be sprayed in a predetermined spraying area evenly uniformly and efficiently.SOLUTION: A matrix of a spraying partition width is created from a near-infrared light image photographed using a drone for farmland aerial photography. Further, an image is obtained by averaging every spraying partition width. A spraying plan screen of the image is obtained by NDVI based on this image. A calculation of a spraying amount is performed after estimating the most effective additional fertilization time. A necessary spraying amount every spraying partition width, spraying patterns A-E and a spraying rate are determined by the spraying width determined from the flight altitude of the drone. The drone for spraying the pesticide is used and it is automatically sprayed, and then the smoothing of protein contents is performed.SELECTED DRAWING: Figure 5
