Identification of fusarium head blight in wheat based on image processing and Deeplabv3+ model

Fusarium head blight is one of the main diseases affecting wheat yield and quality. In order to monitor the occurrence of fusarium head blight in wheat rapidly and effectively, RGB images were acquired by using a digital camera in wheat fields with artificially inoculated Fusarium graminearum in this study, and Deeplabv3+ network model parameters were adjusted and trained on the basis of image preprocessing. Using the lightweight network MobileNet V2 as the network coding module, an identification, and detection model of the wheat ear caused by fusarium head blight was established using the hollow convolution technology based on a deep learning network, and the model was verified and evaluated using the measured data. The results showed that the average accuracy of the model was 0969 2, the Loss value of loss function was 0.103 0, and the mean intersection over union (MIoU) was 0793. The model has a good recognition and detection effect. These results provide a new method for the detection and identification of wheat fusarium head blight.
