Abstract: A system and method for contactless multi-fingerprint collection is disclosed. The contactless multi-fingerprint collection system includes an imaging volume, a user interface configured to provide feedback to the subject regarding a proximity of a hand to a desired imaging location within the imaging volume, and 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. The contactless multi-fingerprint collection system also includes a processor coupled to the at least one image capture device that is 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.
