Crop breeding monitoring method and system based on image processing

The invention discloses a crop breeding monitoring method and system based on image processing. The method comprises the steps of data acquisition, edge detection processing, calculation of the row number of seedlings in a breeding area, calculation of the column number of seedlings in the breeding area, calculation of the density of seedlings in the breeding area and calculation of the height of seedlings in the breeding area. The invention belongs to the technical field of crop breeding, and particularly relates to a crop breeding monitoring method and system based on image processing, according to the scheme, crop breeding images are collected in real time, multiple processes of image processing are simplified into one algorithm, a better noise reduction effect and an edge positioning effect are achieved, the image processing efficiency is improved, and the crop breeding monitoring accuracy is improved. Meanwhile, a function of an open library OpenCV is called to obtain the height of the seedlings, the row
