About this app

Turn your camera into a precise photo ruler & tape measure. NobleGrammetrie measures objects, lines, and distances from any photo — powered by AI photogrammetry.

Ideal for architects, interior designers, woodworking, DIY projects, and surveyors. No internet needed. No data leaves your device.

HOW IT WORKS:
1. Take a photo or load one from your gallery
2. Set four reference points on a known surface
3. Enter the real size (e.g., 21×29.7 cm for A4 paper)
4. Draw lines or polylines on your image
5. Get real-world measurements in centimeters

Even faster: If your photo has a QR code in a known size, the app detects it automatically — no manual reference needed.

FEATURES:
📏 Photo ruler — measure any object from a picture
🧠 AI depth correction (MiDaS neural network) for accuracy
📐 Tape measure mode for distance between two points
🔗 Polyline tool for multiple connected points
📷 QR code auto-detection as size reference
📂 Save, load, and manage measurement projects
📤 Export annotated measurement images for sharing
🔒 100% offline — no internet required
🛡️ Full privacy — all computation stays on your device

PERFECT FOR:
• Architects & interior designers — room dimensions from one photo
• Woodworking & DIY — measure materials without a tape measure
• Surveyors — quick field measurements
• Makers & hobbyists — extract dimensions from reference images
• Contractors — document measurements on site
