We have developed a system based on computer-aided estimations of relics, specifically the face from an excavated skull, which can be performed more easily compared to conventional techniques. We have also constructed a 3D virtual museum, which makes it possible to view the reconstructed face by applying Internet technology.

We gathered all of the information on the skull through a 3D CT scanner, but as the CT data information is very large, we proposed an original information management technique so that it may be possible to use it on standard computers as well. As a result, anthropologists, who usually do not use high speed computers, can easily use the system.

To reconstruct the skull in 3-dimensional virtual space, we used another excavated skull from a similar era and proposed a technique for reconstructing the skull by staying as close as possible to its original features. Based on this we implemented our system.

To paste the skin on the restored skull, we stretched it virtually by applying data measuring the thickness of skin on a modern human and then pasting appendages such as eyes, ears and nose at the end. Our system was able to estimate the face of a person from the Yayoi period.

As it is desirable to give as many people as possible the opportunity to view relics found in archaeological excavation, we have built a virtual museum on the Internet. We calculated an algorithm for reducing information on the reconstructed face and data. In addition, we proposed an interface making it possible for the visitor to view the process of facial reconstruction and experiment with it themselves.

By presenting 3D content on the Internet, it is possible for the user to better understand the material presented.

This paper describes our various proposals regarding the above-mentioned technique for estimating the appearance of the face of prehistoric man, as well as its implementation. We explain how to use the data created by using the system to create a virtual museum on the Internet and introduce concrete techniques so that the user can make use of an exhibit.
