<p>Three dimensional biometric scanner (1) for the capillary mapping of the palm of the hand (2) incorporates two image sensors (5, 6) configured for obtaining a stereoscopic image of a vascular map and where for each image corresponding to each wave length, the depth of each point on the plane is known. Grouping the N images corresponding to the emitted wave N longitudes, a 3D map of the palm of the hand veins is achieved. To achieve a stereoscopic image, a fixed distance (d) between the image sensors (5,6) is needed to be able to calculate the depth of the biometric recognition element Z component.</p> |
