]]> 3D laser scanning with millimeter accuracy for full documentation of architectural details. High-quality interior and exterior scans with millimeter accuracy for full documentation of architectural details. High-quality interior and exterior scans, creation of a 3D geometric model, recording and analysis of defects/cracks, and digital archiving.

Project Facts

  • Scope: 3D laser scanning of Saint Luke Church for millimetre-accurate documentation
  • Purpose: Full geometry capture and architectural detail recording, crack/decay mapping and digital archiving
  • Deliverables: Point cloud, orthophotos, floor plans/sections/elevations, 3D mesh and BIM/IFC as required
3D point cloud of Saint Luke Church — exterior oblique view
Interior nave and dome — high-resolution 3D point cloud
Front elevation with longitudinal section — laser-scanned point cloud

Methodology

  • Interior and exterior scans using a terrestrial laser scanner with target-based registration.
  • Point-cloud registration, georeferencing and accuracy checks.
  • High-resolution orthophotos for façades and interior artworks.

Deliverables

  • Point cloud (E57/PTS/LAZ) structured by area/level.
  • Plans, sections, elevations (DWG/PDF) with reference grids and levels.
  • 3D model (OBJ/FBX/STL) and/or BIM (Revit/IFC) on request.
  • Condition mapping (cracks, detachments, moisture) in dedicated layers.
  • Photo log and concise technical report covering workflow and accuracy.

Accuracy & QA

Overall registration accuracy up to ±2–3 mm (project-dependent), target checks and noise cleaning to ensure reliable datasets for conservation and restoration design.

Use Cases

  • Heritage conservation and restoration studies.
  • Deformation/settlement analysis and comparison with previous surveys.
  • Digital archiving, virtual tours and museum applications.

Outcome

A complete, high-accuracy 3D digital twin of the church, ready for BIM, restoration and heritage documentation.

Need a 3D survey of a monument or building? We provide laser scanning with delivery of point clouds, drawings and BIM models.
