Model card
Technical transparency for the crack-like region detection model.
Model
crs-crack-v0.3-exp
Status
Experimental AI POC
Human review
Required
Purpose
Segment crack-like regions in still images of concrete surfaces to accelerate visual inspection triage. Not intended for structural safety conclusions or physical measurement.
Training dataset (summary)
Curated internal dataset (placeholder) of concrete surface images with weak crack annotations. Full dataset documentation is in development.
Evaluation metrics (placeholders)
- IoU (crack class): 0.42 · illustrative
- Pixel precision: 0.71 · illustrative
- Pixel recall: 0.55 · illustrative
Real evaluation on a held-out benchmark is planned for the next iteration.
Supported input range
Well-lit, orthogonal photographs of dry concrete surfaces. Minimum recommended resolution 8 MP. Wet, painted, or heavily textured surfaces are out of scope.
Known limitations
- No physical width measurement (uncalibrated pixel output only).
- Confusion with surface staining, joints, and wire marks.
- Reduced recall on hairline cracks under 1 px.
- Not evaluated on tunnel or underwater imagery.
Known failure examples
Moisture staining detected as crack-like.
Formwork lines detected as long linear cracks.
