Title:
METHOD AND XR DISPLAY DEVICE FOR DEPTH MAP RE-PROJECTION BASED ON IMAGE AND POSE CHANGES
Document Type and Number:
WIPO Patent Application WO/2021/206367
Kind Code:
A1
Abstract:
A method implemented by an extended reality (XR) display device includes rendering a current image frame received from an external electronic device associated with the XR display device. The current image frame is associated with a current pose of the XR display device. The method further includes receiving an updated image frame from the external electronic device, calculating an updated pose based on one or more characteristics of the updated image frame, and determining whether the updated pose is within a pose range with respect to the current pose. The method thus further includes re-rendering, on one or more displays of the XR display device, a current image frame based on whether the updated pose is determined to be within the pose range.
