Method and apparatus for point cloud chunking for improved patch packing and coding efficiency

An apparatus for encoding a video stream using video point cloud coding, the apparatus comprising:

• at least one memory configured to store program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code comprising:
• obtaining code configured to cause the at least one processor to obtain an input point cloud;
• dividing code configured to cause the at least one processor to the input point cloud into a plurality of chunks, including a first chunk comprising a first plurality of points and a second chunk comprising a second plurality of points;
• first generating code configured to cause the at least one processor to generate a first plurality of patches based on the first plurality of points;
• second generating code configured to cause the at least one processor to generate a second plurality of patches based on the second plurality of points;
• packing code configured to cause the at least one processor to pack the first plurality of patches and the second plurality of patches into an image;
• and
• third generating code configured to cause the at least one processor to generate the video stream based on the image.

A non-transitory computer-readable medium storing computer instructions for encoding a video stream using video point cloud coding that, when executed by at least one processor, cause the at least one processor to:

• obtain an input point cloud;
• divide the input point cloud into a plurality of chunks, including a first chunk comprising a first plurality of points and a second chunk comprising a second plurality of points;
• generate a first plurality of patches based on the first plurality of points;
• generate a second plurality of patches based on the second plurality of points;
• pack the first plurality of patches and the second plurality of patches into an image;
• and
• generate the video stream based on the image.
