Abstract:

With the expansion of communication line coverage, the traditional inspection method for electrical corrosion defects in all dielectric self-supporting (ADSS) optical cables have faced issues of low efficiency and high costs. To address these issues, a detection method for electrical corrosion defects in ADSS communication cables based on adaptive feature extraction was proposed. This method achieved detection of electrical corrosion defects in ADSS cables by making targeted improvements to the YOLOv8n model. Firstly, an ADown downsampling module was introduced into the backbone network to preserve more detailed information about the cable during the downsampling process. Subsequently, a context feature enhancement module was introduced, enabling the algorithm to learn the defect features of optical cables more specifically. Finally, a C2f_DSC module based on feature adaptive extraction was proposed, utilizing the dynamic serpentine convolution feature in the neck network to enhance the extraction of cable area features. Experiments conducted on an ADSS cable electrical corrosion dataset demonstrated that compared to the baseline model YOLOv8n, the proposed algorithm achieved a 2.5% improvement in mAP50 accuracy and a 2.2% increase in mAP50∶95 accuracy, providing a new and effective method for ADSS cable inspection.
