Abstract : In this paper we present an iterative algorithm for camera autocalibration from five or more views of an unknow planar scene. Although our method work provided five views, we aim the particular case of "real time video" autocalibration problems which involves an important number of images. We used a stratified approch to compute a metric reconstruction of camera and scene structure. In a first step, we compute a projective reconstruction of scene structure using planar homography. This intermediate reconstruction is used in a second time in a Kalman Filter which ensure its rectification to recover metric properties.
