Abstract: Provided is a face pose correction apparatus for correcting a face pose, using a person-specific frontal model specialized for input three-dimensional (3D) facial data. The face pose correction apparatus may comprise: a generation unit for generating corrected first facial data by performing a 3D rigid transformation of input 3D facial data on the basis of a pre-stored 3D standard facial model; and a correction unit for generating a first subject-specialized frontal model which is a bilateral symmetry model of the first facial data, and correcting the first facial data by performing the 3D rigid transformation of the first facial data on the basis of the generated first subject-specialized frontal model.
