Simultaneous localization and mapping

Simultaneous localization and mapping is a method of 3D tracking based on camera data of an environment. It uses one or more cameras that are mounted on a rigid body like a headset.
SLAM has stability problems. If the cameras are covered, the device can lose tracking or become erratic.
It operates based on computer vision, heavily relying on feature detection. It is similar in concept to visual inertial odometry (VIO).
One method of SLAM is ORB SLAM2. Another method is ORB SLAM3. Another SLAM-like method is RTAB-Map.
The Hololens 1 and the Magic Leap 1 both use a SLAM-type system for their 3D tracking.
The Oculus Quest 2 uses a tracking system that is some kind of SLAM or VIO.
