# Resources - Official Github: https://github.com/UZ-SLAMLab/ORB_SLAM3 - My clone version: https://github.com/yubaoliu/ORB_SLAM3 - Youtube demo: https://youtu.be/WfY6mCTnFGg 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.
