A framework of augmented reality for geotagged videos

In this paper, we present a prototype system and a framework for the implementation of augmented reality system for a geotagged video. In the proposed system, a live video is captured by a mobile phone and the corresponding geo-coordinates and orientation parameters are recorded at the same time. Based on the parameters, the information about buildings around the center position of the mobile phone is obtained from a database called V-World (http://map.vworld.kr) that is an open platform built by Korean government and freely available through the online. More specifically, the keyhole markup language (KML) is used for the description of the parameters for a captured video, and a detailed description about a chosen building, e.g., the name and the height of the building are obtained from V-World and overlaid on the video. The proposed approach is based on a database freely available through the online and a new database is not required to be constructed for the service, which is very essential to provide augmented reality services.
