Abstract: Methods, devices, and systems for digital space management in virtual reality and augmented reality are described. A method can include a terminal that logs in to a preset application based on a first user identifier, presents a first interface, where the first interface includes a virtual space registration option. In response to an enabling operation of a user for the virtual space registration option, the terminal photographs a first scene to obtain a preview stream, obtains a target geometry, and sends the first user identifier, the preview stream, and the target geometry to a server. The preview stream and the target geometry are used to determine a target virtual space in which a user with the first user identifier has virtual content editing permission in a first virtual space. The first virtual space is a virtual space corresponding to a real world including the first scene. The target geometry is used to represent a form of the target virtual space.

Abstract: This application provides a data processing method and device. The method includes: collecting a first image by using a camera; obtaining first point cloud data of the object based on the first image, where the first point cloud data indicates three-dimensional coordinate values of a surface point of the object in a first camera coordinate system of the first terminal; obtaining pose data of the first terminal in the first camera coordinate system based on the first image; obtaining a two-dimensional feature image based on the pose data, the first point cloud data, and the first image; generating map data based on the first point cloud data, the pose data, and the two-dimensional feature image; and sending the map data to a second terminal or a server.
