Method, system and equipment for calculating curling degree of canopy leaf and medium

The invention discloses a canopy leaf curl degree calculation method, system and device and a medium, and relates to the technical field of biologication.The method comprises the steps that canopy leaf top views of the same plant at the same position and the same angle are obtained at the moment when the leaf stretching area is the largest in one day and at the other moment in the same day; analyzing the top view of the canopy leaf by using image processing software ImageJ to obtain an RGB (Red, Green and Blue) image; adjusting the color, saturation and brightness parameters of the RGB image by using image processing software ImageJ, so that the color, saturation and brightness of canopy leaves displayed in the adjusted image are consistent, selecting a display range in which the color, saturation and brightness of the canopy leaves are consistent, and measuring and calculating the area of the canopy leaves; and analyzing the curling degree of the canopy leaf by using the ratio of the canopy leaf area at the
