Inside Point-n-Capture: Markerless Wound Measurement from a Smartphone

Wound measurement has always been the slowest, least reliable step in the visit. Rulers distort with angle. Sticker markers get lost. Even dedicated imaging devices demand calibration cards and cradles. Point-n-Capture, the imaging agent inside AI-powered wound imaging, removes all of it.

What the agent actually does

Point the phone. Capture. The agent computes length, width, area, and depth estimates directly from the image — no marker in frame, no manual tracing, no calibration step. Results land in the chart in seconds, timestamped and image-anchored.

Why markerless matters

• Speed at the bedside — no fumbling with stickers or rulers on a fragile limb.
• Consistency across clinicians — the agent measures the same wound the same way whether it's the MA, the NP, or the physician holding the phone.
• Evidence for audits — every measurement is tied to the source image, satisfying Medicare's expectation that documentation is anchored to objective data.
• Works anywhere care happens — clinic, mobile visits, bedside, or long-term care. If the phone works, the agent works.

How it fits the rest of the record

Measurements feed the wound healing software trajectory model, which flags stalled wounds before week four. They also populate the SOAP note the AI scribe for wound care drafts, so the number the clinician cites out loud matches the number in the chart. No re-entry, no drift.
