针对高原茶园病害人工检测效率低、光照变化下小尺度病斑检测性能受限等问题,本研究提出轻量化YOLOv8n-GCW模型。基于云南大叶种茶园构建典型病害数据集,通过三重优化提升性能:(1)GhostNet重构特征提取网络适配边缘计算;(2)集成坐标注意力(Coordinate attention,CA)机制增强复杂光照下的鲁棒性;(3)动态损失函数(WIoU)优化重叠病斑定位精度。研究结果表明,改进型模型YOLOv8n-GCW较原先的YOLOv8n模型精确率提升5.6%,召回率提高4.0%,F1分数增长5.3%,平均精度均值(mAP@0.5)上升4.5%,参数量减少42.7%。验证集上关键损失函数下降9.87%~10.74%,推理速度每秒帧数(Frames per second,FPS)达53.84,能满足便携式农业设备轻量化部署需求。消融实验与梯度加权类激活映射(Gradient-weighted class activation mapping,Grad-CAM)可视化进一步验证该模型的有效性。本研究为高原茶园病害智能监测提供了轻量化解决方案,结合农业物联网技术(Agricultural internet of things,Agri-IoT),未来有望扩展至茶园全域智能防控系统,推动智慧茶园的可持续发展。
