An information processing method and an information processing device are disclosed. The information processing method comprises: calculating at least one of a shape parameter and an expression parameter based on a correspondence relationship between a first set of fin a two-dimensional image containing a face of a person and a second set of landmarks in an average three-dimensional face model; and configuring a face deformable model using the at least one of the shape parameter and the expression parameter, to obtain a specific three-dimensional model corresponding to the face contained in the two-dimensional image.
