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: A method for displaying a virtual object is disclosed, applied to an electronic device (10) having a display component (323) and a camera (324). The method includes: detecting an operation of starting an application by a user; in response to the operation, downloading a global submap and storing the global submap in a simultaneous localization and mapping SLAM system of the electronic device (10), where the global submap (123) is a submap corresponding to a location of the electronic device (10) in a global map; and displaying a location and a posture of the virtual object on the display component (323), where the location and the posture of the virtual object are obtained by performing pose calculation based on at least a video image collected by the camera (324) and the global submap (123).

Abstract: This application relates to the automated driving field, and discloses a method for identifying abnormal driving behavior, a system, and a vehicle including the system. The method for identifying abnormal driving behavior includes: obtaining vehicle driving behavior data, and determining, based on the vehicle driving behavior data, whether a vehicle is in a state of suspicious abnormal driving behavior; obtaining current vehicle driving scenario data if the vehicle is in the state of suspicious abnormal driving behavior; and determining, based on the vehicle driving behavior data and the current vehicle driving scenario data, whether the suspicious abnormal driving behavior is abnormal driving behavior. In the technical solutions of this application, current driving scenario information is introduced to an identification process of abnormal driving behavior of the vehicle, so that accuracy of identifying the abnormal driving behavior is improved.

Abstract: A lens module and a head mounted electronic device are provided, where the lens module includes a light emitting unit, a lens barrel, and an eye camera. The light emitting unit is disposed at an end of the lens barrel. The lens module further includes a hollow mounting stage, where the mounting stage is connected to the lens barrel, a cavity of the mounting stage communicates with an inner cavity of the lens barrel, and an optical axis of the eye camera is inclined to an axial direction of the lens barrel. The lens module helps implement an eye tracking function of VR glasses based on a folded optical path, and helps reduce impact of the eye tracking function on imaging quality of the lens module.
