Title:
HEAD-MOUNTED DISPLAY DEVICE CALIBRATION METHOD, APPARATUS, DEVICE AND SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/092638
Kind Code:
A1
Abstract:
Disclosed in the present invention are a head-mounted display device calibration method, apparatus, device and system, and a computer-readable storage medium. The method comprises: acquiring 3D point coordinates corresponding to a target calibration chart card image, wherein the target calibration chart card image comprises an image of a calibration chart card, and the target calibration chart card image is an image, which is captured by a positioning component when a preset image projected by a light machine under the angle of view of a wearer of a head-mounted display device onto the calibration chart card on a see-through display coincides with an actual calibration chart card; determining a correspondence between a projection coordinate system of the light machine and a coordinate system of the positioning component according to the 3D point coordinates; and calibrating the display content of the head-mounted display device according to the correspondence. In the present invention, by determining the correspondence between the projection coordinate system of the light machine and the coordinate system of the positioning component according to the acquired 3D point coordinates corresponding to the target calibration chart card image, the calibration data collection process is simplified, and calibration can be completed by means of just one alignment, thereby saving the calibration time.
