About Pole Annotation

How we measure accuracy, what the models do, and how benchmarks are presented.

What Pole Annotation does

Pole Annotation automates two core tasks from field photos of utility poles:

  • Height Calibration — detects ruler markings and pole tops to derive accurate real-world height measurements from field photos.
  • Height Annotation — annotates heights for pole-mounted equipment and line attachments using markings along the pole, recorded as pixel coordinates in each photo.

Accuracy in context

Reported metrics come from held-out evaluation. Figures below summarize detection and calibration performance on representative validation data. Production accuracy depends on image quality, capture conditions, and how closely the use case matches the training distribution.

  • Calibration — ruler keypoint and pole-top localization errors are measured against ground truth in image space and mapped to real-world tolerances where applicable.
  • Detection — equipment and attachment models are evaluated with standard detection metrics (e.g., precision–recall behavior illustrated in the charts).
