Projection mapping for the enhancement of Estense wall paintings: a workflow for complex surfaces and the management of colors

The present paper constitutes the development of research work carried out in 2018 as part of a project to enhance and promote the Estense architecture. Through the projection mapping technique, we wanted to compensate for the partially compromised decorations of the facades of some Estense dwellings, by building a permanent system capable of periodically projecting their reconstruction directly onto the existing surfaces. The critical issues analyzed during the process carried out in the past year of-fered the basis for the development of a new methodology, attentive to the result from the outset and more consistent with the objectives of enhancing the architecture itself.
