Sub-Millimeter Heritage Preservation
Geosun GS-130X UAV LiDAR Captures Wuhan’s Ziyang Pavilion
The Challenge

Ziyang Pavilion (est. 1487), a heritage site in Wuchang, Wuhan, required non-contact, high-precision documentation due to:

  • 85% summer humidity causing wooden joints to expand
  • Constant cargo ship vibrations from the nearby Yangtze River
  • 217 interlocking dougong brackets with sub-centimeter tolerances
  • Only 2-hour daily scanning windows due to heavy tourist traffic

  • 360° field of view ensured no blind spots
2. Software Breakthroughs
Real-World Issue GeoSoftware Solution Outcome
Missing eave point clouds Multi-angle scan fusion Over 90% data coverage
Vibration distortions Inertial compensation algorithm Positional drift reduced to <0.8mm
Wood grain interference Surface vector analysis Joint gap precision up to ±0.3mm
Tangible Results
  • 37,000-component parametric model enables digital preservation and virtual disassembly
  • Risk heatmap flagged 12 critical areas, with max beam deflection at 4.1cm
  • AR assembly guides projected onto structures for real-time reference by craftsmen
Restorer’s Reaction

“The dougong joint scans frightened our veteran craftsmen – their caliper measurements matched the software data down to 0.3mm."
