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; and generates a bitstream including first information with respect to the prediction residual, second information indicating a bit count of the first information, and third information indicating a bit count of the second information.

A three-dimensional data encoding method comprising:
- calculating a prediction residual that is a difference between information of a three-dimensional point included in point cloud data and a predicted value;
- and
- generating a bitstream including first information for the prediction residual, second information indicating a bit count of the first information, and third information indicating a bit count of the second information.
A three-dimensional data decoding method comprising:
- obtaining, from a bitstream, first information for a prediction residual, second information indicating a bit count of the first information, and third information indicating a bit count of the second information, the prediction residual being a difference between information of a three-dimensional point included in point cloud data and a predicted value;
- and
- calculating the information of the three-dimensional point by adding the predicted value to the prediction residual, using the first information, the second information, and the third information.
A three-dimensional data encoding device comprising:
- a processor;
- and
- memory,
- wherein using the memory, the processor:
