Abstract

A face imaging system for recordal and/or automated identity confirmation, including a camera unit and a camera unit controller. The camera unit includes a video camera, a rotatable mirror system for directing images of the security area into the video camera, and a ranging unit for detecting the presence of a target and for providing target range data, comprising distance, angle and width information, to the camera unit controller. The camera unit controller includes software for detecting face images of the target, tracking of detected face images, and capture of high quality face images. A communication system is provided for sending the captured face images to an external controller for face verification, face recognition and database searching. Face detection and face tracking is performed using the combination of video images and range data and the captured face images are recorded and/or made available for face recognition and searching.

Claims

1. A face imaging system for recordal and/or automated identity confirmation comprising:

a camera unit, comprising;

a camera unit controller;

a video camera for viewing a security area and sending images thereof to said camera unit controller; and

a ranging unit for detecting the presence of a target within said security area and for providing range data relating to said target to said camera unit controller,

said camera unit controller comprising;

a face detection system for detecting a face image of said target;

a face tracking system for tracking said face image;

a face capture system for capturing said face image when said face image is determined to be of sufficient quality.

2. The face imaging system of claim 1, wherein said camera unit includes a rotatable mirror system for reflecting said security area images, said images of said target and said face images into said video camera.

3. The face imaging system of claim 1, including a camera unit communications system for sending said captured face images to an external controller for purposes of face verification and/or face recognition.

4. The imaging system of claim 1, wherein said face detection system uses said range data to assist in detecting said face images.

5. The imaging system of claim 4, wherein said range data includes a distance, an angular location and a width of said target.

6. The imaging system of claim 1, wherein said face tracking system uses said range data to assist in tracking said faces images.

7. The imaging system of claim 6, wherein said range data includes a distance, an angular location and a width of said target.
