Calcul de pose d'un réseau de caméras hybrides à partir de droites

We present a pose estimation approach for a setup of multiple hybrid cameras using line features. From line images across at least three single viewpoint cameras such as perspective, central catadioptric or fish-eye ones, the camera poses are recovered by a decoupling of rotations and translations : rotations are estimated from vanishing points of parallel lines and translations are calculated from known rotations and line images. The 3D lines are reconstructed by the triangulation of projective planes passing through line correspondences. The camera poses and 3D scene are finally refined by bundle adjustment. This technique can be used to recover the topology of a multiple hybrid camera sy…
