3D Modelling for Cultural Heritage Protection

Areas of investigation include:

  • Sub-millimeter 3D scanning and modelling of Cultural Heritage objects using photogrammetric techniques
  • Dealing with point clouds exceeding 100 million converging to 3D models with more than 10 million faces
  • Achieving 3D model accuracy beyond 50 micrometers with commercial high-resolution cameras e.g. 50.3MP Cannon EOS 5DS
  • Simulated ageing of Cultural Heritage objects using model deformation based on rules derived from real accelerated material ageing

Results include:

  • Research: use depth data associated with raster images to reduce borderline effects, increase model precision and lower complexity
  • Research: accommodate penetrating imaging including thermal, ultrasonic, X-ray and Raman.
  • Development: custom CUDA-accelerated (with multi-NVIDIA Titan X) workstation, reducing several times 3D modelling time.
  • Accuracy: 50 micrometers or more with >50MP commercial cameras and expect 25 micrometers with Phase ONE 100MP camera.
