Orientation control for indoor virtual landmarks based on hybrid- based markerless augmented reality


Augmented Reality opens the gate of connection between real and virtual dimension. AR can be used to display any information that by default are not perceived by regular human senses. As such, it is very beneficial to enrich the connection between human and machines. In this paper, an indoor Augmented Reality system is presented in order to display virtual artifacts or ancient heritages in the real, unprepared environment, with the help of camera as the image capturing device. A hybrid sensor-vision markerless tracking algorithm is used as the trackers for camera movement. Vision tracking provides the mapping for unknown environment, and works collaboratively with sensor tracking, so that system can get information where the camera is looking at with respect to the targeted scene. Rendering is then done according to this information. Result shows that the system can display any 3D model in the wide room. The model stays intact when the user moves camera to a different position. The system is also robust to the change of illumination, due to sensor tracking algorithm that does not depend on image features. However, alignment of these virtual objects may fail when rapid, sudden movement occurs in the camera. This study can open more opportunities for AR to be used as a medium of conveying study. © 2013 The Authors. Published by Elsevier Ltd.
