Abstract

A device for user enrollment is adapted to capture an image of a pattern projected on a target and distorted on the three-dimensional (3D) surface of the target, such as a human face, and an image of a two-dimensional (2D) surface of the target. The device can include an illumination unit adapted to project a patterned light onto the surface of the target in an invisible light wavelength, a 3D image capturing device to capture an image of a pattern projected on the target and distorted on the 3D surface of the target. The device can also include a 2D image capturing device adapted to capture an image of a 2D frontal view of the target in visible light. The device can also include an orientation unit that displays the face of the target in order to facilitate the positioning of the target within the proper fields of view.

Claims

1. A system for enrolling a three dimensional image of a target face comprising:

an illumination unit for generating a patterned light signal having a first pattern including at least one location identifier, said patterned light signal projected in a first projection cone, wherein said first pattern is distorted onto the target face to form a distorted first pattern when said target face is positioned within said first projection cone;

a 3D image capturing device for receiving an image of said distorted first pattern when the target face is positioned within a 3D camera cone; and

an orientation unit for generating an image of the target face when the target face is positioned with the first projection cone and the 3D camera cone.

2. The system of claim 1 wherein said patterned light has a wavelength outside of a visible light range.

3. The system of claim 1, further comprising:

a 2D image capturing device for receiving a two dimensional image the target face when the target face is positioned within a 2D camera cone.

4. The system of claim 3, further comprising:

a synchronous controller, coupled to said 3D image capturing device and said 2D image capturing device to enable the substantially simultaneously receiving said image of said distorted first pattern by the 3D image capturing device and said two dimensional image by the 2D image capturing device.

5. The system of claim 1, further comprising:

a biometric unit, coupled to said 3D image capturing device, to identify biometric information about the target face based upon the distorted first image.

6. A method for enrolling a three dimensional image of a target face comprising:

generating a patterned light signal having a first pattern including at least one location identifier, said patterned light signal projected in a first projection cone, wherein said first pattern is distorted onto the target face to form a distorted first pattern when said target face is positioned within said first projection cone;

receiving an image of said distorted first pattern when the target face is positioned within a 3D camera cone; and

generating an image of the target face when the target face is positioned with the first projection cone and the 3D camera cone.

7. The method of claim 6 wherein said patterned light has a wavelength outside of a visible light range.

8. The method of claim 6, further comprising the step of:

receiving a two dimensional image the target face when the target face is positioned within a 2D camera cone.

9. The method of claim 8, further comprising the step of:

substantially simulltaneously receiving said image of said distorted first pattern by the 3D image capturing device and said two dimensional image by the 2D image capturing device.

10. The method of claim 6, futher comprising the step of:

identifying biometric information about the target face based upon the distorted first image.
