摘要： Disclosed herein is technology for generating a digital clone. An apparatus for generating a digital clone includes a standard human body model generation unit for extracting information about appearance deformations based on joint control angles of joints from posture-based appearance deformation examples, generating a parametric shape control engine in which the appearance deformation information is incorporated, and incorporating the parametric shape control engine in a standard mesh-type human body model, thus generating a standard human body model. A unique human body model generation unit receives multi-view image examples based on a change in a posture of an actor, generates a 3D model of the actor based on multi-view image examples, and transfers the standard human body model to the 3D model, thus generating a unique human body model, in which unique appearance deformations of the actor based on the change in the posture of the actor are reflected.
