Abstract:
1. A method for recognition of biometric data, comprising: illuminating an object using a light source; simultaneously acquiring a plurality of images of the object from at least two different imaging directions using at least one optical detector device; acquiring numerical data for each of at least two of the plurality of images using digital image processing; calculating a three-dimensional model of the object from the numerical data of each of the at least two images; comparing the three-dimensional model to a reference model, wherein the reference model is acquired from a plurality of other images; and recognizing the object as a correct object when the numerical data from the each of the at least two images simultaneously correspond with data from the reference model within a predetermined tolerance, wherein the biometric data includes at least one characteristic of one of a finger or a face of a person, wherein the illuminating of the object includes directing an illumination path coming laterally from the light source onto the object and wherein the acquiring of numerical data includes analyzing both a reflected portion and a portion transmitted through the object using at least one of a spectroscopic analysis and a scattered-light-spectroscopic analysis and, wherein a first wavelength is 678 nm and a second wavelength ranges from 808 nm to 835 nm, the first wavelength representing light to acquire at least one of the plurality of images and the second wavelength representing light to acquire at least one other of the plurality of images.
