Abstract: Provided is a method of processing and transmitting three-dimensional data represented as a point cloud.
The method of encoding three-dimensional (3D) data includes: generating a geometry image indicating position information of points, a texture image indicating color information of the points, and an occupancy map indicating occupancy information of the position information of the points in the geometry image, by projecting the points included in the 3D data onto a two-dimensional (2D) plane; generating a filtered occupancy map by performing filtering on the occupancy map; performing image padding on the geometry image and the texture image, based on the filtered occupancy map; and generating and outputting a bitstream including a padded geometry image, a padded texture image, a downsampled occupancy map, and information about the filtering performed on the occupancy map.

Abstract: A method for transmitting data for a three-dimensional image is provided. The method comprises the steps of: generating a plurality of voxelized points corresponding to a plurality of voxels, respectively, from a plurality of points constituting a three-dimensional image; grouping the plurality of voxelized points into a plurality of segments, wherein each of the plurality of segments includes at least one of the plurality of voxelized points; for each segment, projecting the plurality of points and generating a plurality of two-dimensional images; generating a packed two-dimensional image from the generated plurality of two-dimensional images; decoding data for the packed two-dimensional image, and encapsulating same; and transmitting the decoded and encapsulated data.
