Overview
Fine-tuned a transformer model on custom annotations for precise keypoint extraction in utility infrastructure images. Built automated error-analysis loops to continuously improve extraction reliability.
The Problem
Utility infrastructure analysis needs pixel-precise keypoints (attachment heights, wire positions), but generic vision models don't understand domain-specific structures, and expert annotation is too expensive to throw at every failure mode.
The Approach
- 01Built a custom annotation pipeline to capture domain-specific keypoints with consistent quality
- 02Fine-tuned a transformer model on those annotations for precise keypoint extraction
- 03Designed automated error-analysis loops: failure cases are mined, categorized, and fed back into training, so the model improves where it actually fails
- 04Deployed for communication-wire detection in production infrastructure analysis
The Outcome
