  • Digital Archive Project for Cultural HeritagesDevelop methods for acquiring accurate digital models of cultural heritage in all the world. (University of Tokyo)Use for conservation and restoration.Create computer graphics and open to the public through a virtual museum on the Internet.

    Use the acquired digital data for education.(Osaka University)History, Art, Literature, Languages.
