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 dividing the first processing units into a plurality of second processing units; and an encoding step of generating encoded data by encoding each of the plurality of second processing units, the plurality of second processing units defining different spaces, respectively. 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，并将所述第一处理单位划分为多个第二处理单位；以及编码步骤，通过对多个所述第二处理单位的每一个进行编码，生成编码数据，多个所述第二处理单位分别定义不同的空间。
