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