Point-and-Capture wound measurement: calibration-free imaging from one photo
product
How Point-and-Capture turns a single smartphone photo into accurate wound length, width, area, and tissue composition — no ruler, no sticker, no calibration.
Wound measurement has always been the weakest link in documentation: paper rulers distort, disposable calibration stickers get skipped, and inter-rater variability makes trajectory tracking unreliable. Point-and-Capture solves this by extracting geometry and tissue composition from a single uncalibrated photo.
What Point-and-Capture actually does
- Calibration-free geometry. Length, width, and area are computed from one photo without a reference marker or sticker. See the technical walkthrough in Point-and-Capture Wound Imaging: Calibration-Free Measurement from One Photo.
- Tissue segmentation. Granulation, slough, eschar, and epithelial tissue are auto-quantified as a percentage of the wound bed. Details in How WoundScribe Documents Granulation, Slough, and Surrounding Skin from a Single Photo.
- Periwound assessment. Surrounding skin — maceration, erythema, callus — is captured in the same frame.
- Trajectory-ready. Every capture writes into the healing dashboard so week-over-week area change plots automatically.
Why calibration-free matters at the bedside
Mobile providers, nursing home rounds, and busy clinics don't have time to place a sticker, level a camera, or re-shoot when calibration fails. Removing that step is the difference between a measurement captured every visit and a measurement skipped every visit — which is what regulators and payers actually audit against.
Point-and-Capture is part of the broader AI-powered wound imaging stack inside WoundScribe, and pairs directly with the ambient scribe so the note reflects the measured wound bed, not a clinician's estimate.
