Track and Visualise the CHANGEs on Cultural Heritage Surfaces
The conservation and restoration of cultural heritage objects are an occupation of protecting the material witnesses of human art from the past. It is very important to keep track of the occurrence of changes on its surface over time as documenting the changes is the first step to learn more about why they happen and hopefully how to limit the changes. Also, it is a good practice to document it from time to time and pass on the documented changes as well as the restoration process to future generations.
Involvement of virtual reality in the field of cultural heritage can improve the digital documentation of artworks. ESR4 Sunita Saha in CHANGE is currently working on the importance of change analysis and its respective colormap visualization and has recently published a paper on “Augmented Reality in Tracking the Surface Geometry Change of Cultural Heritage Objects”. Link to this is provided in the button below.
In the era of interdisciplinary science, computational analysis and visualization of surface changes can play an important and efficient role to improve the 3D documentation of the restoration of artworks. One of the main challenges for this work is to get access and permission to work on cultural heritage objects without damaging them. We would like to acknowledge the collaboration with the Academy of Fine Arts Warsaw (AFAW) in Poland and the their conservation scientists for their supervision of Sunita’s research and for providing access to their labs and cultural heritage objects. It is of high value to receive feedback on the research results from them.
Various research is going on in change analysis of cultural heritage surfaces in terms of global geometry (shape) change of the surface. Together with AFAW, Sunita has focused on keeping track of local geometry change on cultural heritage surfaces and classify the behavior of change over time. In one of their publications they explained their work motive very clearly and to know more detail about the approach, refer to the paper “Approach to Analysis the Surface Geometry Change in Cultural Heritage Objects” that is available from the link below.
