3D mobile augmented reality in urban scenes

摘要

In this paper, we present a large-scale mobile augmented reality system that recognizes the buildings in the mobile device's live video and registers this live view with the 3-dimensional models of the buildings. Having the camera pose estimated and tracked, the system adds relevant information about the buildings to the video in the correct perspective. We demonstrate the system on a large database of geo-tagged panoramic images of an urban environment with associated 3-dimensional planar models. The system uses the capabilities of emerging mobile platforms such as location and orientation sensors, and computational power to detect, track, and augment buildings in urban scenes.
