Detection of the intersection lines in multiplanar environments: Application to real-time estimation of the camera-scene geometry

This paper describes an integrated system for building a multiplanar model of the scene as the camera is localized on the fly. The core of this system is a robust and accurate procedure for detecting the intersection line between two planes. User cues are used to assist the system in the mapping tasks. Synthetic results and a long video demonstrate the relevance of the method.
