Claim 4:
5. The method according to claim 3, wherein the partitioning spatially the point cloud to obtain the at least one spatial block comprises:
calculating Morton codes of points in the point cloud;
arranging the Morton codes of the points in the point cloud in an ascending order, and determining a maximum value of the Morton codes and a minimum value of the Morton codes;
calculating a difference between the maximum value of the Morton codes and the minimum value of the Morton codes, and shifting the obtained difference to right by N bits to obtain a shifted difference, wherein N is a positive integer greater than or equal to 1; and
partitioning the point cloud into a quantity, which equals to the shifted difference, of spatial blocks when the shifted difference meets a preset range.
