Claim One:
1. A contactless multi-fingerprint collection device for imaging a plurality of fingerprints comprising: an imaging volume configured to receive a hand of a subject for imaging the plurality of fingerprints; a user interface configured to provide feedback to the subject regarding a proximity of the hand to a desired imaging location within the imaging volume; at least one image capture device to capture images of each of the plurality of fingerprints at each of at least two different depths from the fingerprints when the hand is at the desired imaging location; a positioning verification device configured to determine a position of the hand of the subject within the imaging volume so as to identify when the hand is positioned at the desired imaging location within the imaging volume, the positioning verification device being further configured to: determine a location of or track movement of the hand of the subject within the imaging volume; and based on the determined location or tracked movement of the hand, control each of the at least one image capture devices to control the field-of-view and focus depth thereof, so as to provide for capture of in-focus images of the fingers; and a processor coupled to the at least one image capture device, the processor being programmed to: generate a composite image and a contour map of each of the plurality of fingerprints from the images captured at the at least two different depths; and generate a two-dimensional rolled equivalent image of each of the plurality of fingerprints from the composite image and the contour map; wherein the at least one image capture device is adaptable to a size of the hand of the subject to enable the capture of the plurality of fingerprints, with each of the at least one image capture devices having an increased field-of-view for a respective finger of the subject from which it captures images, so as to accommodate a plurality of hand and finger sizes.
