Abstract: Un método de codificación de datos tridimensionales, en el cual: se hace una determinación sobre si usar o no una estructura de árbol octal para codificar una unidad especial en cuestión de entre una pluralidad de unidades espaciales incluidas en datos tridimensionales (S1522); si se determina que la unidad de espacio en cuestión se va a codificar al usar un estructura de árbol octal (SÍ en S1522), la unidad espacial en cuestión se codifica al usar una estructura de árbol octal (S1523); si se determina que la unidad espacial en cuestión no se va a codificar con una estructura de árbol octal (NO en S1522), la unidad espacial en cuestión se codificada al usar un método diferente a una estructura de árbol octal (S1524); e información que indica si la unidad espacial actual ha sido o no codificada con una estructura de árbol octal se agrega una corriente de bits (S1525).

Abstract: A three-dimensional data encoding method includes: obtaining third point cloud data that is a combination of first point cloud data and second point cloud data, and includes geometry information of each of three-dimensional points included in the third point cloud data, and identification information indicating which of the first point cloud data and the second point cloud data each of the three-dimensional points belongs to (S5661); and generating encoded data by encoding the third point cloud data obtained (S5662). In the generating, identification information of each of the three-dimensional points is encoded as attribute information.

Abstract: This three-dimensional data encoding method comprises the steps of: computing a plurality of difference values between each of a plurality of pieces of attribute information of a plurality of three-dimensional points included in point group data and predicted values corresponding to the attribute information (S6591); generating a second code string including, in relation to a first code string in which the plurality of difference values are arrayed, first information (ZeroCnt) indicating the number of continuous zero-difference values which are difference values having a value of zero and second information (value) indicating values of non-zero difference values (S6592); and generating a bitstream including the second code string (S6593).

Abstract: In a three-dimensional data encoding method, a bitstream is generated by encoding a plurality of sub-spaces in a target space that comprises a plurality of three-dimensional points, the bitstream comprising a plurality of encoded data corresponding to the plurality of sub-spaces. In generating the bitstream, a list of information about the plurality of sub-spaces, which are mapped to a plurality of identifiers allocated to the plurality of sub-spaces, is stored in first control information shared by the plurality of encoded data in the bitstream (S4531), and the identifiers, allocated to the sub-spaces that correspond to the encoded data, are stored in each of the headers of each of said plurality of encoded data (S4532).

Abstract: This three-dimensional data encoding method: divides (S2631) a plurality of three-dimensional points included in three-dimensional data into a plurality of three-dimensional point sub-groups including a first three-dimensional point sub-group and a second three-dimensional point sub-group; attaches (S2632) first spatial information of the first three-dimensional point sub-group to a header of the first three-dimensional point sub-group, and attaches second spatial information of the second three-dimensional point sub-group to a header of the second three-dimensional point sub-group; and then encodes (S2633) the first three-dimensional point sub-group and the second three-dimensional point sub-group such that the same can be independently decoded.
