3D augmented reality mobile navigation system supporting indoor positioning function

“Oxford College,” well-known as “the earliest edification institution in northern Taiwan,” was planned by Rev. George Leslie Mackay. It is a typical Chinese and Western style architecture with rich historical and cultural content, now is a Class 2 national monument. This paper took “Oxford College” as an example to develop a 3D augmented reality mobile navigation system that supports the function of indoor positioning. This system collected the historical data to develop the 3D models according to the ratio of actual objectives, and constructed the 3D external and internal structures of Oxford College of the past and present. Moreover, this system combined RFID positioning function with the technology of markerless augmented reality to actively detect the location of visitors and to further instantaneously present 3D and multimedia navigation information on mobile devices.
