This paper introduces a new technology of non-contact 3D fingerprint capture and processing for higher quality fingerprint data acquisition. The system relies on a real-time 3D sensor using structured light illumination (SLI), which generates both texture and detailed ridge depth information. The high resolution 3D scans are then converted into flat equivalent images. As a result, many limitations imposed upon conventional fingerprint capture and processing can be reduced by the unobtrusiveness…
