Abstract
In some implementations, a 360-degree camera includes two wide-angle lenses that provide a spherical view of a scene. The 360-degree camera is configured to be connected to a computing device (e.g., a smart phone) for rendering the captured images. In some implementations, the camera lenses in the 360-degree camera are wide-angle lenses (e.g., 208°) and corrections are performed to the projection of the 3D video data into a planar view to adjust the fisheye effect. A fisheye mapping function is selected that improves the distribution of sampling rays to present a natural view without blurred areas.
