Abstract
A three-dimensional data encoding method includes: calculating coefficient values from pieces of attribute information of three-dimensional points included in point cloud data (S7091); quantizing the coefficient values individually to generate quantized values (S7092); and generating a bitstream including the quantized values (S7093). Each of the coefficient values belongs to any one of layers. In the quantizing (S7092), each of the coefficient values is quantized using a quantization parameter for a layer to which the coefficient value belongs among the layers, and the bitstream includes first information and pieces of second information, the first information indicating a reference quantization parameter, the pieces of second information being for calculating quantization parameters for the layers from the reference quantization parameter.
