Leaf withering detection method, model training method, device, medium and system

The invention discloses a leaf withering detection method, a model training method, a model training device, a medium and a system.The detection method comprises the steps that withering images and withering temperature of leaves are obtained, the withering images comprise high-definition images and infrared images of the leaves, features of the withering images are extracted to obtain a first feature map and a second feature map, and the first feature map and the second feature map are used for detecting withering temperature of the leaves; and correcting the first feature map and the second feature map by using the withering temperature, fusing the corrected first feature map and the corrected second feature map according to a preset proportion to obtain a third feature map, and classifying the third feature map according to a preset classification to obtain a withering result of the leaves. The method can reduce inconsistency caused by different experiences of operators and improve the accuracy of detectio
