Application of Augmented Reality in Campus Navigation

Augmented reality(AR) has the unique quality of providing a direct link between the physical reality and virtual information about that reality. In the application of a visitor visiting the campus with a smartphone, the location and pose information of the phone are acquired and calculated in real time. Then registration in 3D is realized by tracking the visitor's viewpoint and the phone post based on the result data. Also the location and orientation of the campus buildings relative to the visitor are identified. When the visitor is watching campus buildings, additional digital information appears to become part of the real world in the visitor's perception utilized by AR technology. As a result, the visitor not only appreciates the appearances and styles of the buildings directly, but also learn their history from the additional information which they can't intuitively understand.
