Sunflower coverage acquisition method, system and device and medium

The invention relates to a sunflower coverage acquisition method, system and device and a medium, and the method comprises the steps: collecting a plurality of sunflower image data, and carrying out the preprocessing of the data, so as to generate a data set for model training; training is carried out based on the data set to obtain a target network model, and the target network model comprises a color fusion module used for fusing color features and an edge enhancement module used for segmenting the edge of the sunflower disc; after a to-be-recognized sunflower image is obtained, the color fusion module is used for carrying out color feature fusion processing on the to-be-recognized sunflower image to obtain a fusion feature, and the edge enhancement module is used for calculating the spatial relationship of the fusion feature to obtain an output result; and determining the sunflower coverage corresponding to the to-be-identified sunflower picture based on the output result. According to the invention, the c
