Patent ID: 10319071

Abstract:
Techniques and systems are described for mapping 360-degree video data to a truncated square pyramid shape. A 360-degree video frame can include 360-degrees' worth of pixel data, and thus be spherical in shape. By mapping the spherical video data to the planes provided by a truncated square pyramid, the total size of the 360-degree video frame can be reduced. The planes of the truncated square pyramid can be oriented such that the base of the truncated square pyramid represents a front view and the top of the truncated square pyramid represents a back view. In this way, the front view can be captured at full resolution, the back view can be captured at reduced resolution, and the left, right, up, and bottom views can be captured at decreasing resolutions. Frame packing structures can also be defined for 360-degree video data that has been mapped to a truncated square pyramid shape.
