Abstract : We provide a new technique for the Euclidean upgrading of a projective calibration for a set of ten or more cameras with known skew angle and aspect ratio and arbitrary varying focal length and principal point. The proposed algorithm, which is purely linear and thus of very low computational cost, is based on the geometric object given by the set of lines incident with the absolute conic. We include experiments which show the good performance of the technique.
