Potato leaf disease identification method and system

The invention discloses a potato leaf disease identification method and system, and relates to the technical field of pattern identification. The method comprises the following steps: establishing an identification model, deploying the identification model on a server, and adopting a ResNet152 model as the identification model; obtaining a to-be-identified potato leaf image; uploading the to-be-identified potato leaf image to a server through a network; identifying the to-be-identified potato leaf image by using the identification model to obtain a disease type; querying prevention and treatment suggestions corresponding to the disease types; and displaying disease types and prevention and treatment suggestions. According to the method, the deep learning technology is applied to rapid identification of the potato leaf diseases, a visual potato leaf disease identification operation interface is realized by using the ResNet152 model, a peasant household can shoot specific potato disease leaves, and online ident
