Abstract
Disclosed according to embodiments are a point cloud data transmission method, a point cloud data transmission device, a point cloud data reception method, and a point cloud data reception device. The point cloud data transmission method according to embodiments may comprise the steps of: acquiring point cloud data including points through LiDAR equipment provided with laser sensors; encoding the point cloud data; and transmitting signaling data and the encoded point cloud data.
Claims16
A method of transmitting point cloud data, the method comprising:
- acquiring point cloud data containing points by LiDAR equipment having laser sensors;
- encoding the point cloud data;
- and
- transmitting the encoded point cloud data and signaling data,
- wherein the encoding comprises:
- separating the points in the point cloud data into a road and an object;
- constructing a first predictive tree based on the points separated as the road and a second predictive tree based on the points separated as the object;
- and
- compressing the point cloud data based on prediction by applying the first predictive tree and the second predictive tree,
- wherein the signaling data comprises information related to separation of the road and the object.
