The invention provides a correction method for spraying substance material. The substance material is a herbicide, a fertilizer, a pesticide or water, and the correction method is characterized by comprising the following steps: S1, a spraying airplane flies for the first time along a plant strip area with a predetermined width K and a predetermined length L, a camera is used for shooting continuous images of the plant strip area, and during the first flight, spraying is not executed; S2, according to the continuous images, a plant green leaf coverage area percentage M corresponding to each unit length dL of the spraying path is obtained, and the percentage change curve M (dL) of the plant green leaf coverage area along the spraying path is generated; S3, the change curve M (dL) is corrected by using a historical empirical curve of plant green leaf coverage area percentage change to obtain a corrected change curve M (dL) x; and S4, according to the corrected change curve M (dL) x, based on the spraying amount empirical curve, the adjusted spraying amount N corresponding to each unit length dL of the spraying path is obtained.
本发明提供一种喷洒物质材料的修正方法,其中物质材料为除草剂、肥料、农药或水,其特征在于,该方法包括:S1:喷洒飞机沿预定宽度K、预定长度L的植物带条区域第一遍飞行,通过摄像头拍摄植物带状区域的连续图像,所述第一遍飞行期间,不执行喷洒;S2:根据连续图像,获取喷洒路径每单位长度dL对应的植物绿叶覆盖面积百分比M,生成沿喷洒路径的植物绿叶覆盖面积百分比变化曲线M(dL);S3:用植物绿叶覆盖面积百分比变化的历史经验曲线修正所述变化曲线M(dL),获取修正变化曲线M(dL)x;S4:根据修正变化曲线M(dL)x,基于喷洒量经验曲线,获取喷洒路径每单位长度dL对应的调整喷洒量N。
