APPARATUS AND METHOD FOR RECONSTRUCTING THREE DIMENSIONAL FACES BASED ON MULTIPLE CAMERAS
First Claim
1. An apparatus for reconstructing three-dimensional (3D) faces based on multiple cameras, comprising:
- a multi-image analysis unit configured to determine resolution information of images received from a plurality of cameras, and to determine whether the images have been synchronized with each other;
a texture image separation unit configured to separate a texture processing image by comparing resolutions of the received images;
a reconstruction image automatic synchronization unit configured to synchronize images that are determined to be asynchronous images by the multi-image analysis unit;
a 3D appearance reconstruction unit configured to compute 3D coordinate values of the synchronized images, and to reconstruct a 3D appearance image; and
a texture processing unit configured to reconstruct a 3D image by mapping the texture processing image to the 3D appearance image.

Abstract
Disclosed herein are an apparatus and method for reconstructing a three-dimensional (3D) face based on multiple cameras. The apparatus includes a multi-image analysis unit, a texture image separation unit, a reconstruction image automatic synchronization unit, a 3D appearance reconstruction unit, and a texture processing unit. The multi-image analysis unit determines the resolution information of images received from a plurality of cameras, and determines whether the images have been synchronized with each other. The texture image separation unit separates a texture processing image by comparing the resolutions of the received images. The reconstruction image automatic synchronization unit synchronizes images that are determined to be asynchronous images by the multi-image analysis unit. The 3D appearance reconstruction unit computes the 3D coordinate values of the synchronized images, and reconstructs a 3D appearance image. The texture processing unit reconstructs a 3D image by mapping the texture processing image to the 3D appearance image.
