Claim 7:
8. The method according to claim 1, wherein determining a mapping relationship between the expression parameter corresponding to the driving character and the expression parameter corresponding to the driven character according to the driving expression base and the driven expression base comprises:
determining first point cloud data corresponding to the driving character according to the driving expression base and the expression parameter corresponding to the driving character;
determining second point cloud data corresponding to the driven character according to the driven expression base and the expression parameter corresponding to the driven character;
determining a conversion parameter of the first point cloud data and the second point cloud data, the conversion parameter being used for identifying a conversion relationship between the second point cloud data and the first point cloud data; and
determining the mapping relationship between the expression parameter corresponding to the driving character and the expression parameter corresponding to the driven character according to the first point cloud data, the second point cloud data, and the conversion parameter.
