[POSTER] On-site AR Interface with Web-Based 3D Archiving System for Archaeological Project

This paper proposes an AR (augmented reality) interface for on-site use in an archaeological project. We have already been developing a web-based 3D archiving system for supporting the diverse specialties and nationalities needed for carrying out the survey and restoration work of the archaeological project. Our 3D archiving system is designed for the spontaneous updating and sharing of information on findings in order to better enable frequent discussions, through a 3D virtual copy of the field site that a user can visit, explore, and embed information into, over the Internet. Here we present an AR user interface to enhance access from mobile devices at the actual site to the archiving system. Using SFM (structure from motion) and solving the Perspective-n-Point (PnP) problem, a photo taken at the site can be stably matched to the pre-registered photo sets in the archiving system and the archived information is automatically overlaid on the photo, just in the same manner as exploring the virtual version of the site on desktop PCs. Our implementation effectively works on an on-going project in Saqqara, Egypt.
