Automatic modeling of a 3D city map from real-world video

Mixed reality (MR) systems which integrate the virtual world and the real world have become a major topic in the research area of multimedia. As a practical application of these MR systems, we propose an efficient method for making a 3D map from real-world video data. The proposed method is an automatic organization method focusing on video objects to describe video data in an efficient way, i.e., by collating the real-world video data with map information using DP matching. To demonstrate the reliability of this method, we describe successful experiments that we performed using 3D information obtained from the real-world video data.
