Abstract: A method and an apparatus for recognition of biometric data with high fraud resistance, in particular for recognition of characteristics of fingers and of faces, wherein an object is acquired by optical scanning and numerical parameters are acquired by means of digital image processing.

Abstract: The invention relates to a method and a system for recording biometric data, especially for recording the features of the fingers or faces of persons, wherein an object is recorded by optically scanning it and evaluated by digital image processing. The inventive method is characterized in that the object is recorded simultaneously or almost simultaneously by at least two different recording devices, whereby all pixels of the surface to be imaged are imaged in at least two different directions in at least one digital two-dimensional image each and a three-dimensional model of the viewed object is calculated from at least two images.

Abstract: A method for detecting data of an uneven surface of an object includes the following steps: illuminating at least one of stripes and a grid on the uneven surface using at least one light source; detecting, without a touching contact, light reflected from the uneven surface at a plurality of discrete locations so as to create a partial image of the uneven surface at each of the plurality of discrete locations; selectively analyzing each of the partial images; and combining at least portions of the partial images into an overall image of the uneven surface.

Abstract: The present invention relates to a method and an arrangement for acquiring biometic data, particularly for acquiring finger or face characterstics of persons, where an object is acquired by optical scanning and analyzed by digital image processing

Abstract: 1. Touchless biometric recognition 2.1 The invention is underlied by the problem to specify a method of the type initially mentioned, with which an improved touchless biometric recognition is possible cheaply. 2.2 According to the invention, the problem is solved by mutually carrying out the observing, checking and/or correcting using the imaging facilities respectively and thereby acquiring position, attitude and degree of rotation. 2.3 The invention relates to a method for touchless recognition of biometric attributes of a body part, in particular of finger lines, comprising optical imaging from different points of view by several imaging facilities, observing and/or checking the position and/or the attitude of the body part to be recognized and/or correcting the images of the imaging facilities regarding the position and/or the attitude, wherein the shape of the body part is used.

Abstract: 1. Method and arrangement for touchless detection of data of uneven surfaces. 2.1 The present invention is underlied by the problem to specify a method and an apparatus of the initially said type which enable touchlessly scanning of uneven surfaces, in particular of a relief made up of dermal ridges, and creating an image of the surfaces true to original with high contrast. 2.2 According to the present invention, the problem is solved by scanning the surface without a touching contact to optically effective surfaces by illuminating them in a strip-shaped manner and, by using light reflected at discrete locations, creating partial images of the object, which are selectively analyzed and composed to an overall image. 2.
