Archeoguide project will provide access to information in cultural heritage sites in a compelling, user-friendly way through the development of a system based on advanced IT techniques including augmented reality, 3D-visualisation, mobile computing, and multi-modal interaction. Visitors will be provided with a see-through Head-Mounted-Display (HMD), earphone, and mobile computing equipment. A tracking system will determine the location of visitors within the site and audio-visual information will be presented to her/him in context with her exploration, allowing him/her to gain more insight into relevant aspects of the site. The system will be tried out in ancient Olympia in Greece. Particular emphasis will be given to virtual reconstruction of the remains while insight will be provided about the changes that the site has undergone over the years.
The visitors, in the beginning of their session, provide a user profile indicating their interests and background, and they optionally choose a tour from a set of pre-defined tours. The system guides them through the site, acting as a personal intelligent agent. Meeting the functional requirement of displaying augmented reality reconstruction of the temples and other monuments of the site, depends on the position – orientation tracking component of our system. Correct object registration and occlusion handling of course requires having an adequate position and orientation component and a detailed model of the site’s static environment. An accurate model of the site (digital elevation model, orthophotos etc.) was obtained using accurate photogrammetry and site maps.
