3D BIOMETRIC SCANNER

摘要

The invention relates to a 3D biometric scanner (1) for the capillary mapping of the palm of the hand (2), including two image sensors (5, 6) configured to obtain a stereoscopic view of a vascular map, and in which the depth of each point on the plane is known for each image corresponding to each wavelength. A 3D map of the veins in the palm of the hand is obtained by combining N images corresponding to N emission wavelengths. In order to obtain a stereoscopic image there must be a fixed distance (d) between the image sensors (5, 6) so that the depth component Z of the biometric recognition element can be calculated.
