Definitions

  • the invention relates to a method for distortion-free detection, examination and identification of fingerprints and a device for carrying out the method.
  • DE-OS 34 21 220 a device for imaging objects which are arranged at an oblique angle to the imaging plane using a reflection prism is known, which is acted upon by a light source and is assigned to the object to be imaged.
  • This device has the disadvantage that with a concavely curved design of the contact surface to produce a "rolled" impression, in particular due to a strong astigmatism, even with a large number of optical correction elements such as prisms and lenses, distortion-free image field flattening cannot be achieved. In addition to the high manufacturing costs, the large number of error-prone correction elements results in high maintenance and operating costs.
  • the object of the invention is to demonstrate a method and a device for carrying out the method with which, in particular, simple and secure identification of "rolled" fingerprints is possible.
  • the object is achieved in that the finger of the person to be identified is rolled on a fingerprint surface, an undistorted, high-contrast impression image being generated in an optical impression device, in that the impression image is then adapted to the rolling movement of the finger while adapting the digitization process directly digitized or first recorded by a video camera and then digitally lized, then a gray-scale image is generated from the digitized data of the print image, which is then converted into a binary image and then displayed on a monitor and / or stored in a memory and / or printed out and / or forwarded by remote data transmission.

Abstract

Le doigt de la personne à examiner ou à identifier est roulé sur une surface (4) pour empreintes digitales, une empreinte digitale contrastée et non déformée étant produite dans un dispositif optique pour empreintes digitales (17). Ensuite, l'image de l'empreinte digitale est numérisée directement, ou bien tout d'abord enregistrée par une caméra vidéo (6) puis numérisée. A partir des données numérisées de l'image de l'empreinte digitale, on produit une image présentant des demi-teintes qui est ensuite convertie en une image binaire puis affichée sur un écran de contrôle (11) et/ou stockée dans une mémoire (7).
