Digital documentation activities at the Museo delle Civiltà, Rome

On April 17th, 2025, the research teams of CNR ISPC and Sapienza University of Rome carried out an intensive digital documentation campaign at the Museo delle Civiltà in Rome, as part of the ongoing activities of the PRIN KNOT – Knowledge of Things project. The work was conducted in close collaboration with the museum’s staff and curators.

The activity focused on two exceptional examples of Indigenous American heritage preserved in Italy: the Tlahmachayatl mantle and the Quetzalin costume. These highly delicate and culturally significant artefacts were documented using advanced photogrammetric techniques to obtain accurate, high-resolution 3D models.

To ensure complete geometric coverage and minimize handling stress, the mantle was carefully suspended using a custom vertical setup, allowing for full-frontal and multi-angle imaging. The Quetzalin costume was documented through a combined workflow, integrating controlled photographic capture with tailored positioning solutions to ensure three-dimensional consistency across all components.

As part of the campaign, the team also conducted experimental tests using Gaussian Splatting, exploring its potential for representing complex textiles and highly detailed surface features. This experimentation aims to assess how emerging spatial reconstruction techniques can complement traditional photogrammetry and enhance future digital storytelling and visualization strategies within the KNOT framework.

The data acquired are now being processed to produce detailed models that will support further research, diagnostic interpretation, accessibility, and public dissemination. These outputs will contribute to the broader objectives of KNOT, which seeks to reassess, study, and digitally valorize Indigenous American heritage held in Italian institutions through interdisciplinary research and innovative technological solutions.
