Samsung patents method to help VR headsets find their place in familiar rooms
Samsung has filed a patent for a method that helps head-mounted display devices, such as VR headsets, locate themselves within a room they have seen before. The system works by identifying visual landmarks in different views of the scene and creating a multi-level map, or graph, that connects these views based on shared landmarks. This map allows the device to quickly determine its current position and orientation, or pose, by matching what it sees now to the stored map.
In the filing’s own words
Provided is a method for optimizing searching of a previously viewed scene for a head-mounted display (HMD) device including receiving a plurality of views corresponding to a real-world scene, determining landmarks within each view, determining a co-visibility of the landmarks between different views, generating a co-visibility graph based on the co-visibility of the landmarks between the different views, the co-visibility graph including multiple levels, which include nodes that represent at least one view and edges between the nodes that represent the co-visibility of the landmarks between the at least one view, and detecting a pose of the HMD device based on the co-visibility graph of the real-world scene.
What exactly they claim (claim 1)
1. A method for optimizing searching of a previously viewed scene for a head-mounted display (HMD) device, comprising: receiving, by the HMD device, a plurality of views corresponding to a real-world scene; determining, by the HMD device, landmarks included in each view of the plurality of views; determining, by the HMD device, a co-visibility of the landmarks between different views of the plurality of views, the co-visibility indicating same landmarks being included in the different views of the plurality of views; generating, by the HMD device, a co-visibility graph based on the co-visibility of the landmarks between the different views of the plurality of views, the co-visibility graph comprising multiple levels, each level of the multiple levels comprises nodes corresponding to at least one view of the plurality of views, and edges between the nodes that represent the co-visibility of the landmarks between the at least one view of the plurality of views; and detecting, by the HMD device, a pose of the HMD device based on the co-visibility graph of the real-world scene.
