Abstract: This application relates to the field of pose detection technologies, and discloses a method and an apparatus for obtaining pose information, a method and an apparatus for determining symmetry of an object, and a storage medium. The method includes: obtaining a rotational symmetry degree of freedom of a target object (901), obtaining pose information of the target object (902), and adjusting the pose information of the target object based on the rotational symmetry degree of freedom to obtain adjusted pose information (903), where the adjusted pose information is used for displaying a virtual object, and the virtual object is an object associated with the target object.

Abstract: A terminal device sends first information to a cloud device, where the first information indicates a posture and a location of the terminal device at a first moment. Then, the terminal device receives information about a first field of view image from the cloud device, where the first field of view image is a field of view image corresponding to the posture and the location of the terminal device at the first moment. The terminal device displays an image within a field of view range of the terminal device at a second moment based on the information about the first field of view image and a posture change and a location change of the terminal device from the first moment to the second moment.

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.
