Capture from the sky
RTK-positioned drone flights record every elevation at high resolution — safely, in a single visit.
Yihui Tech · An AI company
AI that sees
what others miss.
Yihui Tech builds intelligence for the physical world. Our first product, BuildScan, turns a short drone flight into a complete, defect-by-defect digital twin of any building facade.
Drone capture · 3D reconstruction · Defect mapping · Audit-ready reports
The product
BuildScan — your buildings, fully understood.
A drone-powered inspection platform for building exteriors. Fly once, and BuildScan reconstructs the facade in 3D, maps every defect, and turns it into reports your team can act on.
A measurable digital twin
Photogrammetry rebuilds the structure as an explorable, measurable 3D model.
Find it, pin it, track it
Cracks, spalling, water ingress and more — each pinned to its precise position on the model.
Audit-ready reports
Generate inspection reports in a click and track remediation over time.
How it works
From flight to findings in four steps.
- 01
Fly & capture
Send a drone along the facade — every surface recorded.
- 02
Reconstruct in 3D
Images become an accurate, measurable digital twin.
- 03
Detect & map defects
Defects are pinned to exact coordinates on the model.
- 04
Report & track
Export reports, assign fixes, compare with history.
Why BuildScan
Safer, faster, and complete — every time.
Safety first
Keep crews off ropes and scaffolds. The drone does the climbing.
Hours, not weeks
Survey a full building in a single visit.
Total coverage
Every square metre, captured consistently — not just what someone could reach.
A living record
Re-inspect any time and compare against history.
