A three-dimensional data encoding method, a three-dimensional data decoding method, a three-dimensional data encoding apparatus, and a three-dimensional data decoding apparatus

摘要

The three-dimensional data encoding method encodes a plurality of pieces of attribute information of each of a plurality of three-dimensional points using a parameter (S6701), and a bit including the encoded plurality of attribute information, control information, and a plurality of first attribute control information A stream is generated (S6702), and the control information includes a plurality of types of information corresponding to a plurality of pieces of attribute information, each of which indicates different types of attribute information, and the plurality of pieces of first attribute control information includes: Corresponding to the information, each of the plurality of first attribute control information includes first identification information indicating that it is associated with any one of the plurality of types of information.
