The fingerprint collector is a precise electronic instrument for identifying the identity by utilizing the different characteristics of human fingerprints, and the working principle comprises four functions of collecting fingerprint images, extracting fingerprint characteristics, storing data and comparing fingerprints. The fingerprint collector is a precise electronic instrument for identifying the identity by utilizing the different characteristics of human fingerprints, and the working principle comprises four functions of collecting fingerprint images, extracting fingerprint characteristics, storing data and comparing fingerprints. Wherein, reading fingerprint images is the most important function of the fingerprint collector. By imaging with uneven patterns of a finger fingerprint, we generally refer to the raised patterns as "ridges" and the depressed pattern formation as "valleys", and the process of fingerprint acquisition is essentially that of fingerprint imaging. The principle is that different optical or current resistance feedback signals are obtained according to the difference of the geometrical characteristics, the physical characteristics and the biological characteristics of ridges and valleys, a fingerprint image is drawn by using image processing algorithms of different algorithms according to the magnitude of the feedback signals, and then fingerprint characteristics are extracted and fingerprint characteristic codes are compared on the basis of the fingerprint image through fingerprint identification algorithm software.
