  • Method and arrangement for optical recording of biometric finger data
    Patent number: 7599531
    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.
