3D Scans for Weather-damaged Sculptures

ABSTRACT

The creation and maintenance of different kinds of authenticity is explored for the preservation of weather-damaged sculptures. This is a one-year cultural heritage preservation project led by Juming Museum, to scan stone and copper sculptures by the famous Taiwanese sculptor, Ju Ming. Two approaches were applied to the sculptures. They were based on the use of suitable scanners for the different materials, sizes and conditions, as a way to extend previous studies and facilitate future research. The scanned 3D data led to the identification, inspection, quantification and comparison of deteriorated and damaged parts. By combining existing procedures and minimizing the learning experience for museum researchers, this project not only prepares geometries of different resolutions to make the transfer of the model's data proceed smoothly, but also recommends the virtual tools and setting for research-related work.
