Inside Point-and-Capture Wound Imaging: Calibration-Free Measurement from One Phone Photo

Wound measurement has historically meant rulers, disposable calibration stickers, or a dedicated 3D camera parked in the clinic. WoundScribe's imaging agent replaces that with a single phone photo — captured at the bedside, in the exam room, or from a car between home visits.

What point-and-capture actually does

Point the phone, capture the wound, and the AI-powered wound imaging agent returns a calibrated length, width, area, and tissue composition estimate. No fiducial marker required. No manual tracing. The image, measurement, and tissue breakdown flow directly into the chart.

Why calibration-free matters

• Fewer supplies. No stickers to stock, hand out, or reorder for mobile teams.
• Faster encounters. One tap replaces a two-hand ruler-and-camera routine.
• Consistent measurements. The same algorithm runs on every photo, so week-over-week trends aren't distorted by who held the ruler.
• Works where care happens. Bedside, wound clinic, SNF, or mobile visit — anywhere a phone works.

How the measurement pipeline works

1. Capture. Provider frames the wound and takes one photo in the WoundScribe app.
2. Depth and scale inference. The model infers scale from device metadata and image geometry — no physical calibration target needed.
3. Segmentation. The wound bed and periwound are segmented; tissue types (granulation, slough, eschar, epithelial) are estimated.
4. Chart write-back. Measurements, tissue percentages, and the annotated image drop into the encounter and feed the healing dashboard.

Where it plugs into the rest of the workflow

The measurement isn't a dead-end image — it's the anchor for the SOAP note, the healing trajectory, and the coded claim. Read the full breakdown in point-and-capture wound imaging: calibration-free measurement from one phone photo.
