Ever wondered how a VR headset scans your entire room in just a few seconds? Here is the concept explained in simplest terms. SLAM (Simultaneous Localization and Mapping) is mapping technique used in robotics, computer vision, AR phones and VR headsets to estimate device position while building a map of the environment. It detects stable visual features in every frame, matches them over time and uses depth data to recover their real 3D positions.

By doing this, SLAM maps an accurate world locked coordinate frame. #xr #mixedreality #augmentedreality #vr #metaquest
