Three-dimensional face capturing apparatus and method and computer-readable medium thereof

A method of capturing a 3D face, the method comprising:

• obtaining a face color image;
• obtaining a face depth image;
• aligning, by a computer, the obtained face color image and the obtained face depth image;
• obtaining, by the computer, a 3D face model by 2D modeling of the obtained face color image and covering a modeled 2D face area on an image output by an image alignment module;
• removing, by the computer, depth noise of the 3D face model;
• and obtaining, by the computer, an accurate 3D face model by aligning the 3D face model and a 3D face template, and removing residual noise based on a registration between the 3D face model and the 3D face template,
• wherein the 2D modeling performs the 2D modeling with respect to the face color image using an ellipse, and
• wherein a scale-independent variance (V) is calculated in a depth direction, and compares V with a first threshold to determine whether noise exists in the 3D face model.

At least one non-transitory computer readable recording medium comprising computer readable instructions that control at least one processor to implement a method, comprising:

• obtaining a face color image;
• obtaining a face depth image;
• aligning the obtained face color image and the obtained face depth image;
• obtaining a 3D face model by 2D modeling of the obtained face color image and covering a modeled 2D face area on an image output by an image alignment module;
• removing depth noise of the 3D face model;
• and
• obtaining an accurate 3D face model by aligning the 3D face model and a 3D face template, and removing residual noise based on a registration between the 3D face model and the 3D face template,
• wherein the 2D modeling is performed using an ellipse face color image, and
• wherein a scale-independent variance (V) is calculated in a depth direction, and compares V with a first threshold to determine whether noise exists in the 3D face model.
