Overview

Algorithm evaluation demonstrates enhanced detection accuracy and reduced computational load in aerial power line imagery, indicating viable edge deployment for unmanned aerial vehicles.

Key Points

  • Develop an optimized, lightweight YOLOv11n deep learning model to enable efficient, real-time detection of high-voltage transmission-line insulators on resource-constrained aerial and edge devices.
  • Integrated C3k2MBNV2 modules to reduce model complexity, SCDown layers to preserve spatial features during down-sampling, and C3k2WTDC modules to improve multi-frequency feature representation.
  • Trained and evaluated the modified YOLOv11n architecture using a dataset of 5,750 aerial insulator images captured across various angles, environmental conditions, and background settings.
  • Reduced total parameters from 6.20 M to 3.26 M (a 47.4% reduction) and computational complexity from 20.5 to 12.7 GFLOPs (a 38.0% reduction).
  • Increased detection precision from 91.3% to 93.8%, recall from 73.4% to 75.2%, mAP50 from 71.2% to 73.9%, and mAP50–95 from 65.6% to 67.3%.
