Title:
POINT CLOUD AND MESH COMPRESSION USING IMAGE/VIDEO CODECS
Document Type and Number:
WIPO Patent Application WO/2019/013430
Kind Code:
A1
Abstract:
An decoding device, an encoding device and a method for point cloud encoding is disclosed. The method includes generating, from a three-dimensional point cloud, multiple two-dimensional frames, the two-dimensional frames including at least a first frame representing a geometry of points in the three-dimensional point cloud and a second frame representing texture of points in the three-dimensional point cloud. The method also includes generating an occupancy map indicating locations of pixels in the two-dimensional frames that represent points in the three-dimensional point cloud. The method further includes encoding the two-dimensional frames and the occupancy map to generate a compressed bitstream. The method also includes transmitting the compressed bitstream.
