Abstract: Disclosed are a calibration method, an apparatus, a device and a system for a head-mounted display device, and a computer-readable storage medium. The calibration method includes: obtaining a three dimensional (3D) point coordinate corresponding to a target calibration graphic card image; the target calibration graphic card image includes an image of a calibration graphic card, and the target calibration graphic card image is an image captured by a positioning assembly in response to that a preset image of the calibration graphic card projected by an optical engine on a see-through display coincides with a real calibration graphic card under a perspective of a wearer of the head-mounted display device; determining a corresponding relationship between a projection coordinate system of the optical engine and a coordinate system of the positioning assembly according to the 3D point coordinate; and calibrating display content of the head-mounted display device according to the corresponding relationship.

Abstract: A content display method, apparatus and device. Said method comprises determining an initial position of a user in a VR scene (101); determining, in the VR scene, at least one object to be displayed and the display position of each of said objects in the VR scene (102); according to the display position of each of said objects and the initial position of the user, dividing the VR scene to obtain respective spatial boundaries of the user and each of said objects, and creating respective display spaces for the user and each of said objects (103); and displaying each of said objects in the respective display space 104). The three-dimensional scene-based content display method enables a user to be in a three-dimensional space at every moment, thus providing a better spatial immersion experience.
