Patent ID: 11196977

Abstract:
Methods for unified coding of 3D objects and 3D scenes are described herein. A flexible camera model is used to capture either parts of a 3D object or multiple views of a 3D scene. The flexible camera model is transmitted as metadata, and the captured 3D elements (objects and scenes) are combined in a 2D atlas image that is able to be further compressed with 2D video encoders. Described herein is a unification of two implementations for 3D coding: V-PCC and MIV. Projections of the scene/object of interest are used to map the 3D information into 2D, and then subsequently use video encoders. A general camera concept is able to represent both models via signaling to allow coding of both 3D objects and 3D scenes. With the flexible signaling of the camera model, the encoder is able to compress several different types of content into a single bitstream.
