Abstract:
A three-dimensional data encoding method includes: determining a first maximum bit count for encoded data obtained after encoding at least one of (i) a divisional data unit obtained when point cloud data indicating a three-dimensional point cloud is divided or (ii) a point cloud data unit of the point cloud data before the dividing; and generating a bitstream by encoding (i) items of divisional data obtained by dividing the point cloud data or (ii) the point cloud data before the dividing, to satisfy the first maximum bit count determined. The bitstream includes first bit count information indicating the first maximum bit count.
