Title: Main viewpoint-based panoramic video mapping method
Inventor: WANG RONGGANG
IPC: G06T3/00
Filed: 2018-05-29
Abstract: Disclosed are a panoramic video asymmetrical mapping method and a corresponding inverse mapping method: by means of the mapping methods, mapping a spherical surface corresponding to a panoramic image or video A onto a two-dimensional image or video B; projecting the spherical surface onto an isosceles rectangular pyramid for which a bottom surface is a rectangle, and further projecting the rectangular pyramid onto a planar surface; using isometric projection on a region of a main viewpoint in the projection and using a relatively high sampling density to ensure that the video quality of the region of the main viewpoint is high, while using a relatively low sample density for non-main viewpoint regions so as to reduce bit rate. While ensuring that the video quality of the region of the main viewpoint remains unchanged, the present panoramic video asymmetrical mapping technique greatly reduces the resolution of the remaining regions in the video, effectively reducing the bit rate required for encoding a virtual reality video. The panoramic video asymmetrical mapping technique provides a method for mapping from a planar surface to a spherical surface, and by means of said method, a planar surface video may be mapped back to a spherical surface for rendering and viewing.
