Definitions

  • the invention relates to a method for the contactless detection of biometric features of body parts, in particular finger lines, with optical image acquisition from different perspectives by several
  • Image recording devices with monitoring and / or control of the position and / or posture of the body part to be recognized and / or correction of the images of the recording devices with regard to position and / or posture, the external shape of the body part being used for this purpose.
  • Security systems are used in a variety of applications to prevent unauthorized persons from accessing certain areas. Such areas are, for example, ATMs, laboratory rooms to be kept secret and the like. These systems mainly use facilities for fingerprint and face recognition.
  • DE 101 23 561 AI describes a method for personal identification using the biometric features of the fingertip, the outer
  • Shape of the fingertip in the three spatial dimensions as well as that on the Structures of the fingerprint included on the underside of the finger, including their spatial position and orientation on the fingertip, can be detected as person-specific parameters by using recordings from different perspectives by one or more cameras to create a three-dimensional profile of the fingertip and its
  • the position and rotation of the finger can be determined with an additional camera in front of the fingertip in order to request the user to correct the position or to improve the recognition analysis by the additional information about the degree of rotation of the finger.
  • the invention is based on the object of specifying methods of the type mentioned at the beginning with which improved contactless biometric recognition is possible at low cost.
  • the advantage of the method according to the invention is that only the lowest possible number of image recording devices requires recording from different directions, which fulfill a double function and are therefore better utilized. Improved recognition is possible through the use of the finger image or model over several members.
  • Figure 1 is a schematic representation of an arrangement for use with the inventive method.
  • the two CCD cameras 2.1 and 2.2 are at an angle of 90 ° to one another and lie in the planes of a coordinate system x-y-z separated by the angles 0 and ⁇ , while they take pictures of the object 1.
  • both cameras take repeated recordings until both cameras have determined a finger position that is acceptable for the other camera. This condition can be required for both cameras at the same time or one after the other.
  • the acceptances can either be checked in pairs or for a certain camera by a group or all of the other cameras.
  • Two-dimensional images from certain perspectives or three-dimensional models from the measured data can be used as a reference and as a representation of the measured data.
  • a computational transformation of the images onto a finger into "normal posture” is possible from the posture (that is, position, curvature and degree of rotation) of the finger, that is to say, for example, in a stretched posture without twisting, which is preferably also present in the reference images and models ,
  • the features of the finger limbs and the fingernail ie thickness, width, length, are preferably used to form the models.
  • the degree of rotation of the finger can be calculated very easily from the nail area visible in the photographs.
  • the acceptance range of the recognition is significantly increased by the transformation into a "normal attitude", whereby the process is carried out much faster.
  • feedback can also be given as soon as the recognition has been successful in order to inform the user of the end of the process.

Abstract

Procédé de reconnaissance sans contact de caractéristiques biométriques de parties du corps, en particulier des crêtes papillaires des doigts, qui comporte la prise optique d'images dans des perspectives différentes par plusieurs dispositifs de prise d'images, avec surveillance de la position et du maintien de la partie du corps à reconnaître et correction des images des dispositifs de prise d'images concernant la position et le maintien, la forme externe du doigt étant utilisée pour ce faire.
