Universidad de Zaragoza Exploiting line metric reconstruction from non-central circular panoramas 2017 Access copy available to the general public Unrestricted In certain non-central imaging systems, straight lines are projected via a non-planar surface encapsulating the 4 degrees of freedom of the 3D line. Consequently the geometry of the 3D line can be recovered from a minimum of four image points. However, with classical non-central catadioptric systems there is not enough effective baseline for a practical implementation of the method. In this paper we propose a multi-camera system configuration resembling the circular panoramic model which results in a particular non-central projection allowing the stitching of a non-central panorama. From a single panorama we obtain well-conditioned 3D reconstruction of lines, which are specially interesting in texture-less scenarios. No previous information about the direction or arrangement of the lines in the scene is assumed. The proposed method is evaluated on both synthetic and real images. info:eu-repo/grantAgreement/ES/MINECO/DPI2014-61792-EXP info:eu-repo/grantAgreement/ES/MINECO/DPI2015-65962-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.952 2017 COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE 56 / 132 = 0.424 2017 Q2 T2 0.662 2017 Computer Vision and Pattern Recognition 2017 Q1 Software 2017 Q1 Signal Processing 2017 Q2 Artificial Intelligence 2017 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Saurer, O.
