Three-dimensional data encoding method, decoding method, encoding device and decoding device

The invention provides a three-dimensional data encoding method, a decoding method, an encoding device and a decoding device. The three-dimensional data coding method is used for coding three-dimensional data, and comprises the following steps: a division step: dividing the three-dimensional data into first processing units respectively corresponding to three-dimensional coordinates; and an encoding step for encoding each of the plurality of first processing units, in which it is determined whether or not to encode a second processing unit included in the first processing units with reference to another second processing unit included in the first processing units. 提供三维数据编码方法、解码方法、编码装置、解码装置。三维数据编码方法，对三维数据进行编码，包括：划分步骤，将所述三维数据划分为分别与三维坐标对应的第一处理单位；以及编码步骤，对多个所述第一处理单位的每一个进行编码，在所述编码步骤中，决定将所述第一处理单位中包含的第二处理单位是否参照所述第一处理单位中包含的其他的第二处理单位来进行编码。
