Why 2-Point Manual Calibration is Architecturally Trustworthy
Automated computer-vision tools often hallucinate wall dimensions due to varying lens distortions in uploaded photos. By manually referencing an element of verified physical length (such as an exterior wall dimension or standard 36-inch doorway), DecorMeasure computes an exact pixel-to-foot mathematical conversion ratio without guesswork.
