Abstract
A point cloud data transmission method according to embodiments comprises the steps of: encoding geometry data of point cloud data; encoding attribute data of the point cloud data on the basis of the geometry data; and transmitting the encoded geometry data, the encoded attribute data, and signaling data, wherein the step of encoding the geometry data may comprise the steps of: converting coordinates of the geometry data from a first coordinate system to a second coordinate system; and compressing the geometry data by performing prediction between neighboring frames on the second coordinate system.
