Abstract:
A three-dimensional data encoding method includes: dividing point cloud data into pieces of sub point cloud data by dividing a three-dimensional space into subspaces; shifting each of the pieces of sub point cloud data in accordance with a predetermined shift amount; and generating a bitstream by encoding the pieces of sub point cloud data shifted. The bitstream includes first control information common to the pieces of sub point cloud data, and pieces of second control information for each of the pieces of sub point cloud data, the first control information including first information about a shift amount of each of the pieces of sub point cloud data.
