摘要: 针对植物病害检测中存在的小目标识别困难、特征融合不足及复杂背景干扰等问题,提出一种基于改进YOLOv12的多尺度反馈聚合检测模型。该模型在包含30类植物叶片病害图像的PlantDoc数据集上进行验证,旨在提升复杂环境下病斑区域的检测精度与模型的鲁棒性。通过在YOLOv12框架中引入MEMBA-F模块,利用多分支卷积与双向信息反馈机制实现跨层特征自适应融合,强化病斑边缘和细粒度特征的表达。结果表明,改进模型在PlantDoc数据集上PrecisionRecallmAP50mAP50-95分别达到0.573、0.372、0.582和0.365,较YOLOv8分别提升7.7%、1.4%、3.7%和7.7%,同时保持27.4 ms的推理速度,具备实时检测能力。与基准YOLOv12模型相比,改进后模型的PrecisionRecallmAP50mAP50-95等指标均有进一步提升,验证了MEMBA-F模块在多尺度特征聚合、跨层信息交互以及小目标与细粒度表征方面的有效性。改进模型平衡了检测精度与效率,可为智慧农业中植物病害识别提供参考。

Abstract: To address the problems of difficult small-object recognition, insufficient feature fusion, and complex background interference in plant disease detection, a multi-scale feedback aggregation detection model based on improved YOLOv12 was proposed. The model was validated on the PlantDoc dataset containing images of 30 categories of plant leaf diseases to improve the detection accuracy and robustness of lesion regions in complex environments. By introducing the Multi-Scale Enhanced Multi-Branch Aggregation with Feedback(MEMBA-F) module into the YOLOv12 framework, the improved model employed multi-branch convolution and a bidirectional information feedback mechanism to achieve adaptive cross-layer feature fusion, thereby enhancing the representation of lesion edges and fine-grained features. The results showed that the Precision, Recall, mAP50, and mAP50-95 of the improved model on the PlantDoc dataset reached 0.573, 0.372, 0.582, and 0.365, respectively, which were 7.7%, 1.4%, 3.7%, and 7.7% higher than those of YOLOv8, while maintaining an inference speed of 27.4 ms, demonstrating real-time detection capability. Compared with the baseline YOLOv12 model, the metrics of the improved model were further enhanced, verifying the effectiveness of the MEMBA-F module in multi-scale feature aggregation, cross-layer information interaction, and the representation of small objects and fine-grained features. The improved model balanced detection accuracy and efficiency, providing a reference for plant disease recognition in smart agriculture.
