Abstract
A biometric identification device acquires enrollment data in such a manner as to improve usability while maintaining identification accuracy. The noncontact biometric identification device includes: a sensor that detects feature data including a feature of a part of a living body at a plurality of positions in a range defined in advance in a real space when the part of the living body moves in the range to acquire enrollment data; a processor that arranges a specified number of hyperspheres in a comparison range along a line defined by a locus of the living body in the real space such that the hyperspheres run over the comparison range, do not overlap one another, and have maximum radii, and then selects the feature data detected at one of the positions in the real space closest to the position corresponding to the center of one of the hyperspheres as the enrollment data.
