Abstract:
A three-dimensional data encoding method includes: generating a first predicted value for an item of position information of a first three-dimensional point included in point cloud data, using an item of position information of a reference three-dimensional point included in the point cloud data and angle information; calculating a first difference value between the item of position information of the first three-dimensional point and the first predicted value; and generating a bitstream including the first difference value and the angle information.
