This application discloses a point cloud encoding processing method, a point cloud decoding processing method, and a related device. The point cloud encoding processing method according to an embodiment of this application includes: determining a to-be-encoded point cloud block based on geometric information of a point cloud, and determining a first parameter based on the to-be-encoded point cloud block, where the first parameter is used to indicate the number of bits required to encode a second parameter, and the second parameter is used to indicate a size of the to-be-encoded point cloud block; constructing a predictive tree corresponding to the to-be-encoded point cloud block, and determining a prediction residual of a node in the predictive tree; and performing entropy encoding on the prediction residual based on the first parameter to obtain a geometry encoding result.
