Claims15
A method of transmitting point cloud data, the method comprising:
- pre-processing the point cloud data containing points;
- encoding the pre-processed point cloud data;
- and
- transmitting the encoded point cloud data and signaling data,
- wherein the pre-processing comprises:
- classifying the point cloud data into a plurality of objects;
- mapping a priority level to each of the classified objects;
- and
- controlling a density of at least one of the objects based on position information and the priority level about each of the classified objects.
