Implementation of the augmented reality on PDA

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.
