Apparatus and method for acquiring an image for iris recognition using facial component distance

摘要

A buffer for capturing and storing a person image of one or more persons to be photographed with a camera to acquire an image for iris recognition; a face component element for calculating a face component distance from the person image stored in the buffer An actual distance between the photographed person and the camera is estimated from the distance component calculating unit and the facial component distance calculated by the facial component distance calculating unit, and based on the estimated distance, whether or not the photographer is in the iris photographing space , An eye image is acquired from the person image of the person to be photographed confirmed to be in the iris photographing space by the actual distance estimating section, the quality of the acquired eye image is measured, and the reference quality And an iris image acquiring unit that acquires an iris recognition image that satisfies the degree of the iris recognition using the facial component distance.(FIG.
