This is a speech by Dr. Katsushi Ikeuchi who carried out a project to digitally model Bayon Temple with his student students in Siem Reap, Cambodia. Enjoy watching!

Enjoying amazing ancient structures through Internet technologies is one of
the most promising methods to promote our culture and cultural heritage.
These technologies involve sensing, transmission, and display. In this talk,
I will briefly explain these three aspects, and then focus on sensing
issues, in particular, the technical challenges presented by sensing huge
outdoor structures. I will describe the technical challenges and how we
solved them as we confronted the difficult task of modeling the huge Bayon
Temple in the Angkor ruin in Cambodia. I will show the digital data we
obtained, including the entire structure of the temple, the hundred and
seventy-three faces of deities, and the hidden pediments. I will also
explain some of the technical issues involved in displaying the data we
obtained, using our virtual Aska as an example.
