| Abstract: | A light and compact PDA-based augmented reality system was presented.The system provided the user with a three-dimensional augmented view of the cultural heritage on the commercial PDA device.Accurate registration was achieved by using Fourier-Mellin transform based 2D image registration algorithm and a set of reference images captured from different viewpoint was calibrated and used as reference image database.The client/server infrastructure was employed to reduce the computation burden of the PDA.Experimental test demonstrated the validity and practicability of the PDA-based AR system.Compared with other AR systems,this system can run in the outdoor environment successfully. |
