摘要

A point cloud data transmitting method according to embodiments can comprise the steps of encoding point cloud data and transmitting a bitstream including the point cloud data. A point cloud data receiving method according to embodiments can comprise the steps of receiving a bitstream including point cloud data, decoding the point cloud data, and rendering the point cloud data.

說明書

For example, the pre-processor may perform the above-described operation on all the point cloud data or on the point cloud data indicated by the orientation information and/or the viewport information. The video encoder and/or the image encoder may perform the above-described operation on all the point cloud data or on the point cloud data indicated by the orientation information and/or the viewport information. The file/segment encapsulator may perform the above-described operation on all the point cloud data or on the point cloud data indicated by the orientation information and/or the viewport information. The transmitter may perform the above-described operation on all the point cloud data or on the point cloud data indicated by the orientation information and/or the viewport information.

FIG. 22 is an exemplary block diagram of a point cloud data reception device according to embodiments.

FIG. 22 shows a point cloud system according to embodiments. A part/the entirety of the system may include some or all of the transmission device and reception device of FIG. 1, the encoding process of FIG. 4, the 2D video/image encoder of FIG. 15, the decoding process of FIG. 16, the transmission device of FIG. 18, and/or the reception device of FIG. 19. In addition, it may be included or corresponded to a part/the entirety of the system of FIGS. 20 and 21.
