A 2-minute LiDAR scan, processed with a parametric foot model, delivers precise measurements from anywhere in the world.
2-minute scan / ±1.5 mm accuracy / No equipment needed
See Live Results ↓This is the actual output from a 2-minute iPhone LiDAR scan — fitted to the FIND parametric foot model. Rotate, zoom, and inspect.
Captured with iPhone LiDAR in 2 minutes. Processed with the FIND parametric foot model from University of Cambridge. Ball width is the diagonal distance between the 1st and 5th metatarsal heads; ball girth is the tape-measure circumference through those landmarks.
See the actual data at each stage of processing. Every viewer below is real output — not an illustration.
Each station is captured in ~10 seconds. Total scan time: under 2 minutes. Processing: ~5 minutes.
Manual verification ensures only foot-surface points are used for fitting. Every scan passes through this step before the parametric model runs.
Three steps from pocket to precision. Each one automated.
The app guides you through nine positions around the foot — top, heel, left, front, right, and the diagonals in between. Each station captures a burst of LiDAR depth frames. Total scan time: under two minutes.
A deformable foot template (FIND, University of Cambridge) is fitted to the LiDAR point cloud. The model adjusts to match the exact shape of the foot while maintaining anatomically correct topology.
All standard measurements are extracted directly from the fitted model — foot length, ball width, heel width, ball girth, and EU sizing. No manual measurement needed.
A scan is only worth the confidence you can place in it. Our pilot measurement matches hand measurement to within the natural variability of a skilled measurer.
| Measurement | Topology3D | Manual | Difference |
|---|---|---|---|
| Foot length | 255.4 mm | 256 mm | 0.6 mm |
| Ball girth | 239.7 mm | 242 mm | ~2 mm |
| Ball width | 92.8 mm | 95 mm | ~2 mm |
Within ±1.5 mm on length, ±2 mm on girths and widths.
Surface fitting accuracy: 1.42 mm median (mesh-to-cloud distance, manually verified scan data).
Remotely, quickly, and without specialized equipment.
Your client scans their foot from anywhere in the world and sends you accurate measurements in minutes.
