Simultaneous localization and mapping (SLAM) is a method of 3D tracking that uses cameras to capture images of an environment and uses computer vision to determine the pose of a rigid body attached to the camera(s). It is a kind of egocentric tracking.
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 gadget 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.
