AI Model
CV geometry measurement (experimental): upload front + side photos and enter your height. The front view (upright, full-body, from the front) is used for calculation; the side view is not used this round — it only helps us improve the algorithm. Photos are sent to a local inference server (LAN, not a third-party multimodal provider). CV calibrates pixels→centimetres and standing measurements can only come from the front view, so height is required.
Photo requirements
- Front view: stand upright, shoot from the front, keep your whole body in frame if possible, arms relaxed at your sides.Please enter your height accurately.
- Side view: shoot from the side, keep the whole person in frame, and include the bicycle in the shot (for scale calibration and algorithm improvement).
- Privacy: if you care about privacy you may mask your face, but keep the body outline intact and shoot from the front — do not turn your back to the camera (geometry measurement only accepts the front view). Photos are kept long-term to improve the algorithm; contact us to request deletion.

Phone estimate (classic)
Take a photo, drag the box to fit the person’s outline (arms out), then enter height to estimate. The box aspect ratio is arm span / height.
The simple version derives body measurements from your height using a photo and a box, so accuracy is limited. Photos are used for analysis but not stored; if you are concerned about privacy, you may face away from the camera.
