Title (EN) NON-CONTACT OPTICAL MEANS AND METHOD FOR 3D FINGERPRINT RECOGNITION
(FR) MOYENS OPTIQUES SANS CONTACT ET PROCEDE DE RECONNAISSANCE D'EMPREINTES DIGITALES 3D
Abstract:
(EN) The present invention discloses a method of recognizing 3D fingerprints by contact-less optical means. The novel method comprising inter alia the following steps of obtaining an optical contact-less means for capturing fingerprints, such that 3D optical images, selected from a group comprising minutia, forks, endings or any combination thereof are provided; obtaining a plurality of fingerprints wherein the images resolution of said fingerprints is not dependent on the distance between a camera and said inspected finger; correcting the obtained images by mis-focal and blurring restoring; obtaining a plurality of images, preferably 6 to 9 images, in the enrolment phase, under various views and angles; systematically improving the quality of the field depth of said images and the intensity per pixel; and, disengaging higher resolution from memory consumption, such that no additional optical sensor is required.
(FR) L'invention concerne un procédé de reconnaissance d'empreintes digitales 3D utilisant des moyens optiques sans contact. Ce nouveau procédé comporte entre autres les étapes consistant à: prévoir des moyens optiques sans contact pour saisir les empreintes digitales, p. ex. images optiques 3D, sélectionnées dans le groupe comprenant points caractéristiques, bifurcations, arrêts ou toute combinaison de ceux-ci; obtenir une pluralité d'empreintes digitales, la résolution des images desdites empreintes ne dépendant pas de la distance entre l'appareil photographique et le doigt inspecté; corriger, par une restauration de mise au point erronée et de flou, les images obtenues; obtenir une pluralité d'images, de préférence de 6 à 9 images, dans une phase d'enregistrement, sous divers points de vue et angles; améliorer systématiquement la qualité de la profondeur de champ desdites images ainsi que l'intensité par pixel; et désactiver une résolution supérieure pour éviter de consommer de la mémoire, ce qui rend superflu tout capteur optique supplémentaire.
