US Patent 11969651 Merging local maps from mapping devices

An augmented reality system generates computer-mediated reality on a client device. The client device has sensors including a camera configured to capture image data of an environment. The augmented reality system generates a first 3D map of the environment around the client device based on captured image data. The server receives image data captured from a second client device in the environment and generates a second 3D map of the environment. The server links the first and second 3D together in a singular 3D map. The singular 3D map may be a graphical representation of the real world using nodes that represent 3D maps generated by image data captured at client devices and edges that represent transformations between the nodes.
