THREE-DIMENSIONAL DATA ENCODING METHOD, THREE-DIMENSIONAL DATA DECODING METHOD, THREE-DIMENSIONAL DATA ENCODING DEVICE, AND THREE-DIMENSIONAL DATA DECODING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/159956
Kind Code:
A1
Abstract:
This three-dimensional data encoding method includes: adding, to a bitstream, first information indicating whether a leaf included in an N-branched tree structure (N is an integer of 2 or greater) having multiple three-dimensional points included in three-dimensional data, includes one three-dimensional point or includes two or more three-dimensional points (S2221); and when the first information indicates that the leaf includes one three-dimensional point (Yes in S2222), generating an N-branched tree structure such that the leaf includes one three-dimensional point (S2223) and encoding the N-branched tree structure (S2224), whereas when the first information indicates that the leaf includes two or more three-dimensional points (No in S2222), generating an N-branched tree structure such that the leaf includes two or more three-dimensional points (S2225) and encoding the N-branched tree structure (S2226).
