SYSTEM AND METHOD FOR CREATING A FULL HEAD 3D MORPHABLE MODEL
First Claim
1. A system for generating a full head three-dimensional (3D) morphable model from a two-dimensional (2D) image for use in one of an augmented reality (AR), a virtual reality (VR) and a mixed reality (MR) medium, the system comprising:
- an image capturing unit to capture the 2D image of an object;
an identification module to identify feature points as a collection of principal regions on a face portion of the 2D image, wherein the identification module is configured to correct the principal regions of the 2D image by re-sizing the feature points to obtain scaled principal regions; and
a 3D reconstruction engine module to generate the full head 3D morphable model by mapping the feature points of the scaled principal regions with feature points of principal regions of predefined trained 3D mesh models stored in one or more databases to select one or more predefined 3D mesh models from the predefined trained 3D mesh models, wherein each selected 3D mesh model includes at least one principal region equivalent to a corresponding scaled principal region of the 2D image.

Abstract
The present subject matter relates to a system and a method for generating a full head 3D morphable model. In an aspect, the system includes an identification module to identify one or more feature points as a collection of principal regions of an input 2D image. A 3D reconstruction engine generates the full head 3D morphable model by mapping feature points of the principal regions with corresponding feature points of predefined trained 3D mesh models. A rigging and animation module joins the full head 3D morphable model to a body of an animatable object to obtain a final 3D morphable model. Further, in an aspect, audio content may be added to the final 3D morphable mode to cause the final 3D morphable model to lip-sync with the audio content, and rendered in one of an AR, a MR or a VR medium.
