摘要
Provided are systems and methods for processing 360-degree video data. In various implementations, a spherical representation of a 360-degree video frame can be segmented into a top region, a bottom region, and a middle region. Using a cylindrical equal area projection, such as the Lambert cylindrical equal area projection, the middle region can be mapped into one or more rectangular areas of an output video frame.
