Abstract:
A virtual reality-based apparatus and method to generate a 3D human face model includes, storage of a 3D face model that is an existing 3D face model or a mean-shape face model in at least a neutral expression. A point cloud of the face of the first user is generated based on the plurality of color images and depth information of the face of the first user. A first 3D face model of the first user having neutral expression is generated by a shape-based model-fitment on the stored 3D face model. A shape of the first 3D face model is refined based on a difference between the first 3D face model, the shape-based model-fitment, and the generated point cloud. The display of the refined first 3D face model is controlled to exhibit a minimum deviation from the shape and appearance of the face of the first user.

Claim (Index 1):
A virtual reality-based apparatus, comprising:\n a memory device configured to store a three dimensional (3D) face model that is an existing 3D face model; and circuitry communicatively coupled to a sensing device, wherein the circuitry is configured to:\n generate a point cloud of a face of a first user based on a plurality of color images and corresponding depth information of the face of the first user, wherein the plurality of color images and corresponding depth information of the first user is captured by the sensing device from one or more viewing angles of the face in a neutral expression; \n generate a first 3D face model of the face of the first user with a neutral expression by a shape-based model-fitment on the stored 3D face model using the generated point cloud; \n refine a shape of the first 3D face model based on the shape-based model-fitment and a difference between the first 3D face model and the generated point cloud of the face of the first user; and \n control display of the refined first 3D face model of the face of the first user on the virtual reality-based apparatus such that a plurality of appearance attributes on the refined first 3D face model exhibit a minimum deviation from the shape and appearance of the face of the first user in the captured plurality of color images.
