Title:
DISPLAY DEVICE AND DISTORTION PARAMETER DETERMINATION METHOD, APPARATUS AND SYSTEM THEREOF, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/238564
Kind Code:
A1
Abstract:
The present invention relates to the technical field of display, and provides a display device and a distortion parameter determination method, apparatus and system thereof, and a storage medium. According to the method, a VR image and a reference image which are displayed by a virtual reality (VR) device and photographed by adopting the same target photographing parameter can be acquired; an actual image height between any two target points in the VR image can be flexibly determined on the basis of the reference image, and a distortion parameter of the virtual reality device can be reliably determined on the basis of the actual image height. Therefore, compared with the related technology of obtaining a distortion parameter from a manufacturer, the distortion parameter determined by adopting the method is higher in accuracy, i.e., the reliability of determining a distortion parameter is better.
