Vers une reconstruction 3D de zones urbaines : mise en correspondance de données Gps, Sig et Vidéo
msra(2007)
摘要
D reconstruction of urban environments is a widely studied subject since several years, since it can lead to many useful applications: virtual navigation, augmented reality, architectural pla nification, etc. One of the most difficult problem nowadays in this context is acquisition and treatment of data if very large scale and precise reconst ruction is aimed. In this paper we present a system for computing geo-referenced positions and orientations if images of buildings from non calibrated videos. Providing such information is a mandatory step to well conditioned large scale and precise 3 D reconstruction of urban areas. Our method is based on the fusion of multimodal datasets, namely GPS measures, video sequences and rough 3D models of buildings.
