Adapts Faster R-CNN object detection to find several damage types at once rather than cracks alone: concrete cracks, medium and high steel corrosion, bolt corrosion and steel delamination. Trained on a labelled image set, it runs fast enough per image to underpin a video-based damage detection framework. The abstract does not frame it as a UAV study.

Key findings

  • Mean average precision 87.8% across five damage classes (class APs 90.6, 83.4, 82.1, 98.1, 84.7%)
  • 0.03 s per 500x375 image, enabling a near real-time video framework
  • Dataset of 2,366 labelled images

Limitations

  • Abstract only reviewed
  • Not described as UAV imagery; robustness test used only 11 new images
  • Bounding boxes, not damage size or severity measurement
