Research

From 2014 I’m a fellowship researcher of National Research Council (CNR), the largest public research institution in Italy. I give my contribution in the Virtual Heritage Lab (VHLab), a small team of Institute for technologies applied to cultural heritage (ITABC)

Virtual Heritage Lab is a multi-disciplinary research laboratory driven by different sensitivities that for many years has been developing innovative languages ​​and technologies for the documentation, communication and promotion of cultural heritage.

The team develops concepts, contents, tools and services mainly in the archaeological field combining advanced techniques of 3D Virtual Reconstruction and Computer Vision. VHlab projects and activities demonstrate a strong propensity to use virtual reconstructions both as a scientific database for documentation and as an element of narration for promotion of cultural heritage.

The research projects, in Italy and abroad, are oriented to the digitization and dissemination of the archaeological site through the use – but not only – of multimedia technologies. The results are aimed at satisfying a wide range of users, from a single professional to the public of museums, students, web user.

The laboratory develops new communication languages ​​with the fundamental contribution of Computer Vision. This area of ​​research offers innumerable solutions for generating virtual reconstructions and allowing interactive visualization of the models developed. One of the common objectives is to develop a work flow fast, efficient, reliable, flexible and shareable for a wide range of archaeological artifacts, from small objects to entire monumental complexes. The final result are heterogeneous: 3D models optimized for real-time use with immersive HDM devices, 3D databases, 360° photo/video, interactive contents for museum installations or large exhibition spaces, 2D drawings typically used in the professional field, videos or animations to be shown in public.

The activity of 3D survey and virtual reconstruction of artifacts and archaeological scenarios is followed by a team within the laboratory, of which I am a member, which uses different technologies: Laser Scanner, GPS, Topography, Photogrammetry. The reconstruction and editing of the models makes extensive use of Photogrammetry and Image_based Modeling (Debevec) tools and software. In the galaxy of theories and techniques related to these two sectors – which often intersect or even overlap – my personal contribution is to develop realistic 3D photo restitution methods and technologies with particular attention to the Spherical Photogrammetry or Multi Image Spherical Photogrammetry (Fangi).

Main topics

  • Photogrammetry (Range Image and UAV)
  • High Resolution Panoramic Photography
  • Multi Image Spherical Photogrammetry
  • Spherical Image-based Modeling and Rendering
  • Structure from Motion and Dense Stereo Matching
  • 3D Mesh Reconstruction and Editing
  • Omni directional High Dynamic Range Images

The laboratory follows numerous activities of dissemination and promotion of cultural heritage in museums or cultural events. My task is first and foremost to contribute to the design of experience using concepts and tools typical of Computer Vision and of Digital Art. I’m in charge of design,  prototyping and setting of multimedia infrastructures (structure / hardware / software) for museums or expo. I’m developing Real Time Image Processing applications using vvvv programming environment, a powerful textual/visual hybrid language.

I developed complete prototypes and software applications for interactive multimedia installations like

  • Holographic Projection (Pepper’s Ghost)
  • Spacial Augmented Reality and 3D Projection Mapping
  • VR Multi Interaction (Touchscreen, Eyes Tracking, MIDI, etc.)
  • VR Multi Screen (Free Planar Surfaces)
  • VR for CAVE or DOME (Planar, Curved or Spherical Surfaces)
  • Interactive Multi Contents Player
  • Mixed Reality Showcase (Virtual Reality on Real Artifact)
