Omnidirectional FTV

摘要

FTV (Free-viewpoint Television) enables users to view a 3D scene by freely changing the viewpoint. It was developed based on ray-space representation. Omnidirectional FTV is 360-degree video with free viewpoint function. Omnidirectional FTV with horizontal parallax is realized by using 3-dimensional (3D) spherical ray-space. Here, 3D spherical ray-space is extended to 4D to realize vertical parallax. Ray capture and view synthesis are analyzed in 4D spherical ray-space and verified experimentally. Omnidirectional views with full parallax are successfully generated.
