Abstract :
The context of this study is 3D city modeling. The goal is to automatically compute the initial registration of a GIS model and a video sequence. The proposed method is divided into two parts. First, a coarse registration is obtained using GPS data and the theory of epipolar geometry. Then, a simultaneous pose and correspondence determination is done thanks to RANSAC algorithm applied on line features. Experiments on real sequences show that a correct registration is achieved.
