Abstract:
A system and method for capturing biometric data from a hand includes a low resolution camera for recognizing the existence of a hand and determining when the hand is in an optimal position and orientation to capture the biometric data. A plurality of high resolution cameras photographs respective sections of the palm and fingers while several lights illuminate the sections from different directions in rapid sequence. A processor then tiles together the respective images, matches the friction ridges between adjacent images, adjusts the images to account for curvature, and selects individual pixels from the several images to obtain maximum contrast. Conversions of the resulting images into standard formats, such as grayscale, black and white, or simulated rolled ink fingerprint equivalents are also included.
