In this paper, an innovative method for the digital representation of ancient books is proposed. Specifically, this approach consists of the reconstruction of the book three-dimensional geometry through photogrammetric images obtained from different viewpoints using Structure from Motion. In addition, both reflectograms in the mid-wave infrared spectral range and thermograms, recorded by pulse thermography, have been adopted since they enable a depth-resolved characterization of the manuscript. The final result is a 4D digital model of the codex, which allows both the visualization of the geometry of the book and stratigraphic exploration of the features buried beneath the surface. Data obtained from humanistic studies and diagnostic surveys have been also mapped onto this model in the form of semantic annotations. Finally, several outputs were developed, including a 3DWeb platform and a holographic showcase designed for museums, with the goal of creating an interdisciplinary experience with the ancient codex.

Abstract
In this paper, an innovative method for the digital representation of ancient books is proposed. Specifically, this approach consists of the reconstruction of the book three-dimensional geometry through photogrammetric images obtained from different viewpoints using Structure from Motion. In addition, both reflectograms in the mid-wave infrared spectral range and thermograms, recorded by pulse thermography, have been adopted since they enable a depth-resolved characterization of the manuscript. The final result is a 4D digital model of the codex, which allows both the visualization of the geometry of the book and stratigraphic exploration of the features buried beneath the surface. Data obtained from humanistic studies and diagnostic surveys have been also mapped onto this model in the form of semantic annotations. Finally, several outputs were developed, including a 3DWeb platform and a holographic showcase designed for museums, with the goal of creating an interdisciplinary experience with the ancient codex.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
