Abstract: This disclosure provides a data processing method. The method includes: A backup server receives a metadata obtaining command, where the metadata obtaining command is used to obtain file system metadata in a first format, and the command includes an identifier of a to-be-read target directory. The backup server obtains, from a metadata storage area of an archive storage based on the identifier of the target directory, file system metadata that is in a second format and that corresponds to the target directory, converts the file system metadata that is in the second format and that corresponds to the target directory into file system metadata that is in the first format and that corresponds to the target directory, and returns the file system metadata.

Abstract: A method, an apparatus, and a medium for determining a pose are provided. The method includes: receiving a query image sent by a terminal and N text fields included in the query image; determining a candidate reference image based on a prestored correspondence between a reference image and a text field and based on the N text fields; determining an initial pose of the terminal at the first location based on the query image and the candidate reference image; and sending the initial pose to the terminal. According to the method, a candidate reference image is queried based on a text field, and an initial pose of a terminal is obtained based on a candidate reference image with higher accuracy. Therefore, the obtained pose is more accurate.

Abstract: A visual localization method and apparatus are provided. The method includes obtaining a captured first image, determining a first pose based on the first image and an aerial model, determining whether a ground model corresponding to the first pose exists in an aerial-ground model, and when the ground model corresponding to the first pose exists, determining a second pose based on the ground model. The aerial-ground model includes the aerial model and the ground model mapped to the aerial model, a coordinate system of the ground model is the same as a coordinate system of the aerial model, and localization accuracy of the second pose is higher than localization accuracy of the first pose. Performing fine visual localization based on the ground model can improve accuracy and a success rate of localization.

Abstract: The present disclosure relates to computer system power supply methods, apparatuses, and devices. In one example method, a power management circuit in a computer system obtains a parameter that affects a power supply capability, determines, based on the parameter, the power supply capability of a power supply to provide a burst power for a component in the computer system, and controls the power supply to supply power to the component in the computer system based on the power supply capability. The power management circuit determines the power supply capability of the power supply based on the real-time dynamic parameter that affects the power supply capability, and controls the power supply to provide electric energy of the burst power for the component in the computer system based on the power supply capability of the power supply.

Abstract: The technology of this application relates to a pose determining method. The method includes obtaining a first image, when first pose information determined based on the first image meets a pose anomaly condition, displaying prompt information for indicating to photograph a target object, and obtaining, by using the target object in the target image captured by a user based on the prompt, second pose information that does not meet the pose anomaly condition. When high-precision pose information cannot be determined, pose positioning is implemented by using the target object in a scenario. In addition, in a process of determining pose information of a terminal device, prompt information for indicating the user to photograph the target object is displayed, and the user is indicated to photograph the target object, thereby avoiding that the user does not know how to operate or scan an invalid target object.
