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.

Disclosed herein is an apparatus and method for estimating the joint structure of a human body. The apparatus includes a multi-view image acquisition unit for receiving multi-view images acquired by capturing a human body. A human body foreground separation unit extracts a foreground region corresponding to the human body from the acquired multi-view images. A human body shape restoration unit restores voxels indicating geometric space occupation information of the human body using the foreground region corresponding to the human body, thus generating voxel-based three-dimensional (3D) shape information of the human body. A skeleton information extraction unit generates 3D skeleton information from the generated voxel-based 3D shape information of the human body. A skeletal structure estimation unit estimates positions of respective joints from a skeletal structure of the human body using both the generated 3D skeleton information and anthropometric information.
