ABSTRACT
Augmented reality (AR) mixes computer-generated, synthetic elements (3D/2D graphics, 3D audio) with the real world in such a way that synthetic elements appear to be part of the real world. Various techniques are used to accomplish this, including magnetic tracking of position and orientation, and video-based tracking. This paper focuses on video-based AR, in which a camera is used to generate an image of the real world; the image is then processed to determine where the computer-generated elements should be displayed. Video-based AR is particularly popular among AR researchers because of the accuracy that can be achieved in video image processing.
