METHOD AND SYSTEM FOR SELECTIVE CONTENT PROCESSING BASED ON A PANORAMIC CAMERA AND A VIRTUAL-REALITY HEADSET

摘要

The gaze position of an operator wearing a virtual reality headset displaying a video stream defines preferential viewing areas of the display. Starting from a reference gaze position, for each subsequent contrasting gaze positions, the virtual reality headset receives the video stream control data comprising three spatial coordinates and a temporal coordinate expressed as a cyclic video-frame index. Send it to the view adapter. The view adapter stores the contents of a plurality of latest video frames of the video stream in a circular content-buffer, and stores control data of a plurality of latest gaze positions in the circular control-buffer. The content filter in the view adapter determines the preferred view area around the gaze position according to the control data held in the recursive control-buffer, and extracts the partial content of each frame held in the recursive content-buffer according to the preferred view area.
