- Abstract:
-
The accurate detection of typical fittings in transmission line images is the premise of fault detection. This study proposes a typical fittings detection method that combines occlusion structure information and scene association information to address the problems of low detection accuracy and missed detection of the common target detection model, such as dense distribution and serious occlusion of the fittings. Based on the classical Faster R-CNN detection model, the method extracts features of the entire image of fittings as scene association information, learns the intersecting area information between the marking frames as occlusion structure information, uses a graph to model the feature of fittings, scene-related information and occlusion structure information, and constructs a structure reasoning module through the information transmission mechanism of the gated recirculating unit to complete the joint inference detection of the category and position of fittings. Experiments with eight types of fittings with occlusion relationships are chosen to validate the effectiveness of the proposed method. The Faster R-CNN model shows an mAP value of 81.30%, while the proposed model has an mAP value of 84.15%. The experiments show that the proposed method can improve the detection accuracy of serious occlusion fittings to some extent and that it has laid a good foundation for the subsequent fault diagnosis of the fittings.
