野生动物学报为有效防治珍稀鸟类误撞输电线路导致的鸟类伤亡与线路跳闸事故，提出一种基于改进YOLOv8模型的鸟类智能识别方法。根据发生撞线事故的鸟类信息及输电线路周边调研结果，构建了包含11种珍稀鸟类的图像数据集，采用加雾加噪操作进行图像增广，用于模拟真实输电线路场景。通过在YOLOv8网络的特征提取部分加入大型分离卷积注意力模块，减少模型参数量，增强模型对于鸟类特征的提取速度；在特征提取和特征融合网络中增加辅助检测头，增强模型对于鸟类特征的学习能力，进而提高检测性能。算例分析表明，改进模型的平均精度均值、F1分数 ...

Gaoya dianqi基于无人机航拍的电力巡检成为目前绝缘子缺陷检测方法的主流，但当遇到图像特征不够明显或干扰特征较多等问题时，绝缘子缺陷识别困难，检测精度不高。由此，提出了一种基于改进YOLOv5s的绝缘子缺陷检测方法。首先，重新设计卷积模块，然后将CA注意力机制与其相融合，并且在主干网络加入注意力机制与颈部网络的特征图进行多尺度特征融合，抑制复杂环境下的干扰特征，专注缺陷特征提取；其次，对空间金字塔池化结构（SPPF）进行改进，扩大感受野，减少被模型过滤掉的有用信息；接着，将Transformer与C3模块中的残差结构 ...
