三次元データ符号化方法、三次元データ復号方法、三次元データ符号化装置、及び三次元データ復号装置
Document Type and Number:
Japanese Patent JP7478668
Kind Code:
B2
Abstract:
A three-dimensional data encoding method includes: calculating difference values each of which is a difference between (i) a corresponding one of pieces of attribute information of three-dimensional points included in point cloud data and (ii) a predicted value corresponding to the corresponding attribute information (S6591); generating a second code sequence including first information (ZeroCnt) and second information (value), the first information indicating a total number of zero difference values consecutive in a first code sequence in which the difference values are arranged, the second information indicating a value of a non-zero difference value included in the difference values, the zero difference values being included in the difference values and having a value of 0 (S6592); and generating a bitstream including the second code sequence (S6593).
