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 acquiring biometric data of a finger a surface to be imaged includes touchlessly and simultaneously imaging a finger surface to be imaged along at least three different directions into digital images, wherein each point of the surface to be imaged is imaged along at least two of the directions and wherein the surface to be imaged extends from a first nail edge across a finger-ball to a second nail edge. Subsequently, a geometric basic model for at least a part of the finger is determined using at least one of the digital images. Pre-warped images are calculated by geometrically pre-warping the digital images using the geometric basic model. Additionally, a three-dimensional model of the surface to be imaged is reconstructed using a stereoscopic analysis of the pre-warped images and at least one finger characteristic is determined using the three-dimensional model.

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.
