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 display module for a head-mounted display device includes a display assembly, an optical imaging assembly, and a virtual image location adjustment assembly. The display assembly is configured to display an image. The optical imaging assembly is configured to form a virtual image based on the image. The virtual image location adjustment assembly is configured to adjust at least one of the optical imaging assembly and the display assembly to adjust the virtual image to a target location. The virtual image location adjustment assembly adjusts the optical imaging assembly and/or the display assembly.
