Special Issue Information

Dear Colleagues,

The reliability and security of power systems are key to ensuring the sustainable and stable operation of modern infrastructure. Long-term exposure of transmission, transformation and distribution equipments to harsh natural environment will inevitably lead to aging, corrosion, structural damage and other defects over time. If these defects are not identified and evaluated timely and accurately, the consequences may range from reduced energy efficiency and increased operation and maintenance costs to local failures and even large-scale power outages, resulting in significant economic losses and social operation interruption. Therefore, regular inspection of these equipments and timely repair of defects are very important to ensure the safe and reliable operation of power system.

In recent years, rapid advances in computer vision, artificial intelligence, robotics and sensor technology have provided innovative solutions to these longstanding challenges. The Vision‑Based Defect Detection in Power Systems (VDDPS) method utilizes drones, inspection robots or fixed monitoring systems equipped with high‑resolution cameras, infrared thermal imagers, LiDAR and other sensors to efficiently capture high‑precision visual data from power assets. By processing this data with advanced deep learning models, VDDPS significantly enhances the efficiency, accuracy and safety of inspection operations.

This Special Issue aims to assemble the latest research advances, innovative solutions and practical experiences in the field of VDDPS, creating a high‑level platform for scholarly exchange and fostering deeper application and continued progress in this domain. We welcome original contributions that explore various facets of VDDPS, including, but not limited to, the following:

  1. VDDPS in challenging and complex environments;
  2. VDDPS with multimodal data fusion techniques;
  3. Lightweight model design for VDDPS;
  4. Few-shot or zero-shot learning in VDDPS;
  5. High-resolution image processing for VDDPS;
  6. Self-supervised and contrastive learning for VDDPS;
  7. Human-in-the-loop and interactive VDDPSs;
  8. Interpretable and explainable AI models in VDDPS;
  9. Vision enhancement techniques under adverse weather and lighting conditions;
  10. Three-dimensional data processing based on LiDAR point clouds;
  11. Benchmark datasets and evaluation metrics for VDDPS.

Detecting small insulator defects in unmanned aerial vehicle (UAV) imagery remains challenging due to low resolution, complex backgrounds and scale variation, which degrade the performance of existing detectors. This study aims to develop a highly efficient and accurate model for real-time insulator defect inspection on resource-constrained UAV platforms. This paper proposes POLD-YOLO, a novel lightweight object detector based on YOLO11. The key innovations include: (1) A backbone enhanced by a PoolingFormer module and Channel-wise Gated Linear Units (CGLUs) to boost feature extraction efficiency; (2) An Omni-Dimensional Adaptive Downsampling (OD-ADown) module for multi-scale feature extraction with low complexity; (3) A Lightweight Shared Convolutional Detection Head (LSCD-Head) to minimize the number of parameters; (4) A Focaler-MPDIoU loss function to improve bounding box regression. Extensive experiments conducted on a self-built UAV insulator defect dataset show that POLD-YOLO achieves a state-of-the-art mAP@0.5 of 92.4%, outperforming YOLOv5n, YOLOv8n, YOLOv10n, and YOLO11n by 3.6%, 1.6%, 1.4%, and 1.6%, respectively. Notably, it attains this superior accuracy with only 1.55 million parameters and 3.8 GFLOPs. POLD-YOLO establishes a new Pareto front for accuracy-efficiency for onboard defect detection. It demonstrates great potential for automated power line inspection and can be extended to other real-time aerial vision tasks. Full article
