 # ORB-SLAM3
 
 ### V0.2: Beta version, 21 Jul 2020
-**Authors:** [Carlos Campos], [Richard Elvira], [Juan J. Gómez], [José. M. M. Montiel](http://webdiis.unizar.es/~josemari/), [Juan D. Tardos](http://webdiis.unizar.es/~jdtardos/)

 ORB-SLAM3 is the first real time SLAM library able to perform **Visual, Visual-Inertial and Multi-Map SLAM** with **monocular, stereo and RGB-D** cameras, using **pin-hole and fisheye** lens models. In all sensor configurations, ORB-SLAM3 is as robust as the best systems available in the literature, and significantly more accurate.
