Chrysanthemum similar variety fine granularity identification method, device and equipment and storage medium

The invention relates to the technical field of similar chrysanthemum variety recognition, and discloses a similar chrysanthemum variety fine granularity recognition method, device and equipment and a storage medium, and the method comprises the steps: carrying out the chrysanthemum image position coding of an input chrysanthemum image through an encoder, and obtaining a node network diagram; aggregating and updating features in the node network diagram by adopting an image feature information extraction network to obtain image features of the chrysanthemum image; performing chrysanthemum character word vectorization on the extracted image features to obtain word vector codes of the chrysanthemum image; and performing vector extraction on the chrysanthemum images of all varieties by using the trained similarity feature extraction network, calculating the cosine similarity between the target chrysanthemum variety and other chrysanthemum varieties, and determining similar varieties of the target chrysanthemum v
