Abstract

Wheat diseases seriously restrict the safety of wheat production and food quality. For farmers and agriculture technicians, diagnosing the disease with the naked eye is not suitable for modern precision agriculture. Deep learning has shown promise in crop disease diagnosis, but accuracy and speed remain a significant challenge in natural field conditions. In this study, a novel DAE-Mask method based on diversification-augmented features and edge features was proposed for intelligent wheat disease detection. DAE-Mask used Densely Connected Convolutional Networks (DenseNet) for preliminary feature extraction, and a backbone feature extraction network combining Feature Pyramid Network (FPN) and attention mechanism was designed to extract diversification-augmented features. To accelerate DAE-Mask, an Edge Agreement Head module based on Sobel filters was designed to compare edge features during training, which improved the model’s mask generation efficiency. We also built a multi-scene wheat disease dataset, MSWDD2022, containing images of wheat stripe rust, wheat powdery mildew, wheat yellow dwarf, and wheat scab. Our model achieved detection speed of 0.08s/pic. On MSWDD2022, our model with mean average precision (mAP) of 96.02% outperformed YOLOv5s, YOLOv8x, SSD, EfficientDet, CenterNet, and RefineDet by 7.79, 1.32, 3.54, 4.79, 9.77, and 5.29 percentage points, respectively. On the public dataset PlantDoc, our model with mAP of 57.68% outperformed YOLOv5s, YOLOv8x, SSD, EfficientDet, CenterNet, and RefineDet by 27.76, 6.48, 14.43, 11.79, 19.40, and 13.40 percentage points, respectively. Finally, the DAE-Mask was deployed on WeChat Mini Program to realize the real-time detection of in-field wheat diseases. The mAP reached 92.78%, and the average return delay of each image was 1.43s.

DAE-Mask:基于深度学习的新型小麦田间病害自动检测模型
小麦病害严重制约着小麦生产安全和粮食质量。对于农民和农业技术人员来说,用肉眼诊断病害并不适合现代精准农业。深度学习在作物病害诊断方面已显示出良好的前景,但在自然田间条件下,准确性和速度仍然是一个重大挑战。本研究提出了一种基于多样化增强特征和边缘特征的新型 DAE-Mask 方法,用于小麦病害的智能检测。DAE-Mask 使用密集连接卷积网络(DenseNet)进行初步特征提取,并设计了一个结合特征金字塔网络(FPN)和注意力机制的骨干特征提取网络来提取多样化增强特征。为了加速 DAE-Mask 的生成,我们设计了一个基于 Sobel 过滤器的边缘协议头模块,用于在训练过程中比较边缘特征,从而提高了模型的掩码生成效率。我们还建立了一个多场景小麦病害数据集 MSWDD2022,其中包含小麦条锈病、小麦白粉病、小麦黄矮病和小麦赤霉病的图像。我们的模型实现了 0.08s/pic 的检测速度。在 MSWDD2022 上,我们的模型的平均精度(mAP)为 96.02%,比 YOLOv5s、YOLOv8x、SSD、EfficientDet、CenterNet 和 RefineDet 分别高出 7.79、1.32、3.54、4.79、9.77 和 5.29 个百分点。在公开数据集 PlantDoc 上,我们的模型的 mAP 为 57.68%,其性能分别比 YOLOv5s、YOLOv8x、SSD、EfficientDet、CenterNet 和 RefineDet 高 27.76、6.48、14.43、11.79、19.40 和 13.40 个百分点。最后,在微信小程序上部署了 DAE-Mask,实现了小麦田间病害的实时检测。mAP 达到 92.78%,每张图像的平均返回延迟为 1.43s。
