CULTURAL HERITAGE APPLICATIONS 

[2018 - 2022]  I've co-coordinated the project OPEN CULTURAL HERITAGE:  The Modern Rio in collaboration with Vivian Luiz Fonseca (FGV/CPDOC)

ABSTRACT:   The use of three-dimensional (3D) digitisation technologies for producing 3D digital replicas of cultural heritage assets has acquired greater prominence in recent decades. A 3D digital replica is a digital asset that reproduces as extensively as possible the visual information of a physical object including its shape, colour and texture information. 

In this research, we take advantage of the maturity of the digitization technology to propose a methodology for producing 3D digital replicas of open cultural heritage assets. By open we mean both in the sense of their location in open spaces and the fact that they are openly accessible to the public. The contribution of the research is a trialed methodology, which is based on an open source pipeline and photogrammetry.  We also join the debate on copyright issues related to the ownership of any resulting digital content. Our focus is on outdoor sculptures, placed on roads, streets, parks, and other public areas.

[2015 - 2017] I've been coordinating the Digitising 3D Chinese Ivory Junk project in collaboration with Ricardo Guerra Marroquim (LCG/COPPE/UFRJ), Museu Historico Nacional (MHN) and CIRG, University of Brighton, UK. 

ABSTRACT:   The project is the result of ongoing efforts on engaging with museums in Brazil, in this particular case the National History Museum in Rio de Janeiro, in order to explore the potential of 3D technologies for the documentation and dissemination. For the pesent study, we have focused on their important collection of ivory artefacts.  The selected items included various figurines as well as a carved Junk Boat from East Asia. 

METODOLOGY:  The approach used for producing the 3D digital replicas was a combination of approaches. Digitising the figurines used a simpler photogrammetry based approach while the Chinese Junk recquired a combination of approaches.  For the latter, photogrammetry was combined with a model synthesising approach informed by the images. Potential use of 3D printing was also subject of investigation.
