SCALE UNCALIBRATED
No measurement selected
Ready. Press Start Camera.
To calibrate: select Set Reference, tap both ends of an object of known length, enter its length in inches, then press Calibrate Reference. For another measurement select Measure Points and tap two points. Pixel distance is always available. Inch results are planar estimates only: reference and measured points must be at the same depth and viewing plane, without camera movement or scale change. Camera/landmark data stays in this browser; models are downloaded from external hosts.
