Abstract
A method for level partition of a point cloud includes that: a point cloud bitstream is decoded; a maximum permissible value of a first syntax element in the point cloud bitstream is determined as a constant value; the first syntax element is decoded to obtain a value of the first syntax element; a number of levels of detail (LODs) in a process of decoding the attribute information is determined according to the value of the first syntax element; and the attribute information is decoded according to the number of the LODs and the geometry information, to determine a reconstructed point cloud of the point cloud.
