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.

Abstract: Embodiments of the present invention provide a method for detecting a network transmission status, and a related device. The method for detecting a network transmission status may include: measuring and calculating, by a first communications device, a transmission status characterization parameter used to indicate a status of network transmission between the first communications device and a second communications device; and if the transmission status characterization parameter meets a preset condition, sending, by the first communications device, a Real-Time Transport Protocol packet to the second communications device. Technical solutions provided in the embodiments of the present invention facilitate improving of estimation precision of available network bandwidth on a transmit end, and further improve bandwidth utilization and reduce phenomena such as a delay and an intermittent stop, thereby improving user experience.

Abstract: A pose determining method, which may be applied to the field of photographing and image processing, includes: obtaining a target image, where the target image includes a target parking space mark and a target parking space line, and a target parking space corresponding to the target parking space mark includes the target parking space line; and determining pose information based on the target parking space mark and the target parking space line. The pose information indicates a corresponding pose of a terminal during photographing of the target image. According to the pose determining method, the pose information may be determined based on the target parking space mark and the target parking space line, to implement positioning.
