Claim 9:
10. A three-dimensional data decoding device comprising:
a processor; and
memory, wherein
using the memory, the processor:
performs motion compensation on a second point cloud by using motion from a decoded first point cloud to the second point cloud, to generate a third point cloud having a position which is a position of the second point cloud that is shifted based on the motion;
merges the first point cloud and the third point cloud, to generate a reference point cloud;
decodes an N-ary tree structure of a current point cloud using the reference point cloud, where N is an integer greater than or equal to 2; and
generates a decoded point cloud of the current point cloud from the N-ary tree structure of the current point cloud.
