The invention discloses a method for correcting a prescription map of a rice machine field-inserting weeding unmanned aerial vehicle, and relates to the field of rice field pesticide application measurement. According to the method for correcting the prescription map of the unmanned aerial vehicle for weeding in the field inserted by the rice machine, the unmanned aerial vehicle is used for shooting pictures from the position above the field inserted by the rice machine and flies in the east, south, west and north directions from the position over a target weed group serving as a center point, and the flight path is a sector with the shooting height over the target weed group serving as the radius; in the flight process, the change of the included angle between the lens surface of the unmanned aerial vehicle camera and the horizontal plane is taken as a reference value, one picture is shot every 10 degrees of the included angle, nine prescription maps are shot in total, four groups are obtained in four directions, each group of pictures is analyzed, and calculation is performed according to the change of the angle and the change of the plaque proportion of grass in the whole picture. Then three-dimensional calculation conversion is carried out according to the two-dimensional calculation structure, so that the area and height of each weed group are accurately analyzed, and the pesticide spraying amount is adjusted according to the analysis result.

    本发明公开水稻机插田除草无人机处方图修正方法,涉及稻田施药测量领域。该水稻机插田除草无人机处方图修正方法,通过使用无人机从机插田的上方进行画面拍摄,以目标杂草群为中心点,从其正上方向东南西北四个方向进行飞行,飞行轨迹是以正上方的拍摄高度为半径的一扇形,飞行过程中以无人机相机镜头面与水平面的夹角变化为参考值,夹角每改变10度,拍摄一张照片,一共拍摄9张处方图,四个方向获取四组,针对每一组照片进行分析,根据角度变化和草丛在整个照片的斑块占比变化来进行计算,然后根据二维计算结构进行三维计算转化,从而对每一块杂草群的面积和高度进行精准分析,根据分析结果来调整药物喷洒的量。
