Document Type and Number:
WIPO Patent Application WO/2022/110903
Kind Code:
A1
Abstract:
Disclosed is a method for rendering a panoramic video. The method comprises: acquiring a current image frame from a video source, and generating texture map data, wherein a gaze point region is determined according to a viewing angle of a perspective camera, and image pixels outside the gaze point region are rendered at a resolution lower than a resolution of image pixels in the gaze point region; constructing a spherical rendering model, and performing mapping according to the texture map data to convert the current image frame into a three-dimensional image; and projecting the three-dimensional image onto a two-dimensional screen. Also disclosed are a system for rendering a panoramic video, an electronic device and a computer-readable storage medium. In the invention, image pixels outside a gaze point region of a user are rendered at a lower resolution, thereby optimizing rendering efficiency, and preventing occurrence of a lag when a video is playing.
