- Abstract:
-
To tackle the issues of visual inseparability and semantic ambiguity in identifying transmission line bolt defects, a new method using joint structure–semantic relationship graph knowledge reasoning is proposed. Initially, a semantic expression module extracts feature class mappings that highlight the discriminative attributes of each bolt. Subsequently, the structural relationship graph captures contextual bolt information and establishes spatial relationships across different scales. Utilizing a graph convolutional neural network and cooperative learning, the semantic relation graph nodes are updated with structural and semantic knowledge derived from the bolt attributes. Finally, the network employs label co-occurrence information from the bolt training data set to improve the accuracy of defect recognition. In the experimental stage, 13 types of bolt properties across 3 types of typical fittings were examined. Comparative experiments show that the method proposed in this study outperforms other methods in identifying bolt defects, boosting accuracy by 8.12% over the baseline model.
