Point-n-Capture: How Guided Wound Imaging Works
woundcare
A closer look at Point-n-Capture: how guidance on angle, distance, and light leads to border detection and markerless wound measurement.
Point-n-Capture is the capture workflow in WoundScribe. It is built to make a wound photo repeatable, whoever is holding the phone.
The problem it addresses
Wound measurements drift when technique lives with one person. Angle, distance, and light change the result, and a ruler or marker adds steps at the bedside.
What happens during capture
- Guidance. The app prompts for angle, distance, and light before the photo.
- Border detection. The wound edge is detected from the image.
- Measurement. Length, width, and area are calculated without a marker or ruler.
- Review. The clinician checks the outline and confirms.
Why consistency matters
Research shows that clinicians measuring the same wound by hand often disagree, while agreement improves with a measurement app. Giving every user the same guidance each visit narrows the gap further.
What it feeds
Confirmed measurements flow into the note and forms, so there is no retyping. They also feed the healing dashboard, where trends show healing, stalling, or worsening.
Limits to know
- Photos capture the surface. Depth, tunneling, and undermining are documented separately.
- Very poor lighting or heavy glare can affect border detection, so review the outline.
- The clinician remains responsible for the final measurement.
