THREE-DIMENSIONAL DATA STORAGE METHOD, THREE-DIMENSIONAL DATA ACQUISITION METHOD, THREE-DIMENSIONAL DATA STORAGE DEVICE, AND THREE-DIMENSIONAL DATA ACQUISITION DEVICE

摘要

A three-dimensional data storage method includes: acquiring one or more units in which an encoded stream generated by encoding point cloud data is stored (S4781); and storing the one or more units into a file (S4782). The storing includes storing, in control information for the file, information indicating that data stored in the file is data generated by encoding the point cloud data. For example, the information further may indicate an encoding method used in the encoding of the point cloud data out of a first encoding method and a second encoding method.
