DEVICE FOR CAPTURING PERSON-SPECIFIC DATA

摘要

The disclosure relates to a device for capturing person-specific data of a person, wherein the person-specific data comprises a facial image of the person, wherein the device has a camera for recording the facial image of the person, a lighting apparatus, and a semi-transparent mirror, wherein the semi-transparent mirror is arranged between the person and the camera, wherein the semi-transparent mirror is oriented such that, on the side of the semi-transparent mirror facing towards the person, the optical path of light incident on the semi-transparent mirror is parallel to the optical path of the portion of this light reflected back by the semi-transparent mirror, wherein the lighting apparatus is used to illuminate the person from the front, wherein the device also has a control unit for capturing an image, by generating light by means of the lighting apparatus in order to illuminate the face of the person and, during the illumination, capturing a first image of the face of the person by means of the camera, capturing a second image of the face of the person by means of the camera without generation of the light, forming a first differential image of the first image and the second image, wherein in the first differential image the face of the person is freed from the background, wherein the person-specific data comprises the first differential image as the facial image.

1. A device for capturing person-specific data of a person, wherein the person-specific data comprises a facial image of the person, wherein the device has a camera for recording the facial image of the person, a lighting apparatus, and a semi-transparent mirror, wherein the semi-transparent mirror is arranged between the person and the camera, wherein the semi-transparent mirror is oriented such that, on the side of the semi-transparent mirror facing towards the person, the optical path of light incident on the semi-transparent mirror is parallel to the optical path of the portion of this light reflected back by the semi-transparent mirror, wherein the lighting apparatus is used to illuminate the person from the front, wherein the device also has a control unit for capturing an image, by:
generating light by means of the lighting apparatus in order to illuminate the face of the person and, during the illumination, capturing a first image of the face of the person by means of the camera; capturing a second image of the face of the person by means of the camera without generation of the light; and forming a first differential image of the first image and the second image, wherein in the first differential image the face of the person is freed from the background, wherein the person-specific data comprises the first differential image as the facial image.
