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.2017http://zaguan.unizar.es/record/7559410.1016/j.patrec.2017.05.006http://zaguan.unizar.es/record/75594oai:zaguan.unizar.es:75594info:eu-repo/grantAgreement/ES/MINECO/DPI2014-61792-EXPinfo:eu-repo/grantAgreement/ES/MINECO/DPI2015-65962-RPATTERN RECOGNITION LETTERS 94 (2017), 30-37by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
