Method for detecting biometric data esp. of finger-prints and facial features etc, requires detecting object by optical scanning with digital image processing of numerical characteristics

摘要

A method for detecting biometric data, such as finger prints etc in which an object (1) is illuminated by a light source and detected by optical scanning and ascertained by digital image processing of the numerical characteristics. The object is simultaneously detected from at least two different recording directions, and a three-dimensional model of the observed object is calculated from at least two images and compared with a reference model, where the object (1) is identified correctly if the data obtained from the images agrees simultaneously with the data of the reference model. An independent claim is included for a device for carrying out the method.
