Abstract This paper tackles a recent challenge in patrol image processing on how to improve the identification accuracy for power component, especially for the scenarios including many interference objects. Our proposed method can fully use the patrol image information from live work, and it is thus different from traditional power component identification methods. Firstly, we use long short-term memory networks to synthesize the context information in a convolutional neural network. Then, we constructed the Mask LSTM-CNN model by combining the existing Mask R-CNN method and the context information. Further, by extracting the specific features belonging to the power components, we design an optimization algorithm to optimize the parameters of Mask LSTM-CNN model. Our solution is competitive in the sense that the power component is still identified accurately even if the patrol images contain much interference information. Extensive experiments show that the proposed scheme can improve the accuracy of component recognition and has an excellent anti-interference ability. Comparing with the existing R-FCN model and Faster R-CNN model, the proposed method demonstrates a significantly superior detection performance, and the average recognition accuracy is improved from 8 to 11%.
