How Museums Use Agisoft Metashape to Create 3D Archives and Virtual Exhibits

Posted on by admin

Museums around the globe are embracing digital technologies to preserve artifacts, engage visitors, and broaden access to cultural heritage. Agisoft Metashape has emerged as a leading photogrammetry solution, enabling institutions to generate high‑resolution 3D models of objects, artworks, and entire exhibition spaces. These models form the backbone of digital archives and virtual exhibits, ensuring that precious collections can be studied, shared, and experienced long into the future.

Why Photogrammetry Matters for Museums

Traditional conservation and cataloging rely heavily on photography and manual measurement. Photogrammetry, by contrast, uses overlapping images to reconstruct an object’s geometry and texture with millimeter accuracy. This offers museums:

  • Complete visual records: Capture details like surface wear, inscriptions, and color nuances.
  • Non‑invasive scanning: Avoid contact with fragile artifacts.
  • Scalability: Digitize everything from small coins to life‑size sculptures and entire galleries.
  • Accessibility: Share 3D models online for researchers, educators, and virtual visitors.

Step 1: Planning and Setup

Effective 3D capture begins with careful planning. Museums should consider:

  • Lighting: Use diffuse, even lighting to minimize harsh shadows and glare on glossy surfaces.
  • Background: Place objects on neutral, matte backgrounds or turntables for small items to simplify masking.
  • Overlap: Aim for 70–80% overlap between photos to ensure robust feature matching.
  • Control targets: Position coded markers or scale bars for accurate alignment and scaling in Metashape.

Step 2: Image Capture

Use DSLR or mirrorless cameras with prime lenses for the highest image quality. For large artifacts or architectural elements, a tripod and panoramic rigs help maintain consistent framing. Small objects may be placed on a motorized turntable, capturing images every 10–15° around the object.

Record metadata—object name, accession number, date, and camera settings—for each capture session to maintain archival integrity.

Step 3: Processing in Agisoft Metashape

Import images into Metashape and execute the standard workflow:

  • Align Photos: Generate the sparse point cloud and estimate camera positions.
  • Build Dense Cloud: Create a detailed point cloud with millimeter‑level detail.
  • Build Mesh: Convert the dense cloud into a 3D mesh; use depth maps for complex surfaces.
  • Build Texture: Bake high‑resolution textures for realistic color reproduction.

Throughout processing, verify GCP accuracy, remove misaligned images, and adjust depth filtering to eliminate noise while preserving fine details.

Step 4: Creating Digital Archives

Once models are complete, museums archive them in multiple formats:

  • OBJ/FBX/GLTF: Interactive 3D models for web and VR platforms.
  • Point Clouds (LAS/PLY): For advanced research and measurement.
  • Orthophotos: High‑res 2D projections for catalog records.
  • PDF Reports: Automated processing logs, accuracy metrics, and thumbnails.

Metadata—like object dimensions, capture date, and version history—are stored alongside each file to ensure long‑term traceability.

Step 5: Building Virtual Exhibits

Virtual exhibits allow global audiences to explore collections online. Common approaches include:

  • WebGL Viewers: Use libraries like three.js or ModelViewer to embed 3D models directly into museum websites.
  • CesiumJS or Mapbox: Geolocate architectural scans within interactive maps or campus layouts.
  • VR Tours: Import models into Unity or Unreal Engine to create immersive gallery experiences.
  • 360° Panoramas: Stitch room‑scale scans into navigable virtual tours with hotspots linking to detailed 3D objects.

Interactive features—such as annotations, measurement tools, and audio guides—enhance educational value and engagement.

Case Studies

  • The British Museum: Digitized small artifacts and created an online 3D gallery using Metashape and Sketchfab.
  • Uffizi Gallery, Florence: Scanned Renaissance sculptures and provided AR‑enabled visitor guides.
  • Smithsonian Institution: Developed VR tours of historical rooms with interactive exhibits built in Unreal Engine.

Conclusion

Agisoft Metashape empowers museums to preserve, document, and share their collections in unprecedented detail. By combining high‑quality photogrammetry with web and VR technologies, institutions can create lasting digital archives and immersive virtual exhibits—ensuring cultural heritage is safeguarded and accessible to audiences worldwide. As digital engagement grows, Metashape will remain a cornerstone in modern museum practice.
