摘要
Disclosed herein are systems and methods for extracting two-dimensional fingerprints from high resolution three-dimensional surface data obtained from contactless, stand-off sensors. The system may include a three-dimensional sensor that generates three-dimensional surface data of a hand and one or more fingers of a subject and a processor, coupled to the three-dimensional sensor, and a memory associated with the processor, in which the processor executes instructions stored in the memory collect three-dimensional surface data of the subject hand and one or more subject fingers generated by the three-dimensional sensor, estimate a hand pose of the subject based on the collected three-dimensional surface data, unroll one or more two-dimensional fingerprints from the extracted fingerprint information, determine a fingerprint quality score for each of the one or more two-dimensional fingerprints and for each of the one or more two-dimensional fingerprints that have a sufficiently high determined fingerprint quality score, store the two-dimensional fingerprint.
