摘 要：針對使用無人機進行絕緣子識別實時性的要求，以感受野模塊（RFB）網絡為基礎，提出了一種基于RFB模型改進的輕量型架構。使用MobileNetV3網絡作為特征提取主干，設計了新的感受野模塊RFB-X，并使用Focal-loss損失函數解決正負樣本不平衡問題。實驗結果表明，該模型提高了絕緣子的檢測速度和準確率。

Abstract: In response to the real-time requirements of using UAVs for insulator identification, based on the receptive field module (RFB) network, a lightweight architecture based on the improvement of the RFB model is proposed. Firstly, mobile MobileNetV3 is used as the main feature extraction module, then a new receptive field module RFB-X is designed, and finally the Focal-loss function is used to solve the imbalance of positive and negative samples. Experiments show that the model improves the speed and accuracy of insulator detection.
Key words: lightweight model; RFB; UAV; insulator detection; real time
