Abstract
A three-dimensional data encoding method includes: calculating a prediction residual that is a difference between information of a three-dimensional point included in point cloud data and a predicted value; quantizing the prediction residual using a quantization parameter; determining, using the quantization parameter, a second bit count of second information indicating a first bit count of first information on the prediction residual quantized; and generating a bitstream including the first information, the second information, and third information indicating the second bit count.
