Claim 4:
5. The method according to claim 4, wherein performing global fitting on the three-dimensional face mesh and the global area of the second three-dimensional face model comprises:
performing the global fitting on the three-dimensional face mesh and the global area of the second three-dimensional face model according to the second correspondence, to calculate a second posture parameter of the three-dimensional face model of the target object after the global fitting;
adjusting a shape base coefficient of the second three-dimensional face model according to the second posture parameter, to obtain a shape base coefficient of the three-dimensional face model of the target object after the global fitting;
adjusting an expression base coefficient of the second three-dimensional face model according to the second posture parameter, to obtain an expression base coefficient of the three-dimensional face model of the target object after the global fitting; and
obtaining, according to the second posture parameter, the shape base coefficient, and the expression base coefficient, the three-dimensional face model of the target object after the global fitting.
