Abstract
Purpose - We present a vision based wide area registration method for camera phones based mobile augmented reality applications.Design/methodology/approach - Our system can be used in wide area scenarios and provides an accurate registration between real and virtual objects. The tracking system uses a drift-free 6 DOF tracker based on prebuilt multiple maps, and can be initialized using our compacted key-frames recognition engine.Findings - Given the current location and camera pose, we show how the corresponding virtual objects can be accurately superimposed even in the case of varying user positions. Originality/value - We also build a mobile AR based virtual exhibition prototype to prove the usability of the proposed method.
