Embodiment 1

[0012] Embodiment one: see attached figure 2 shown.

[0013] An adaptive fingerprint recognition system includes a fingerprint collection unit, a fingerprint imaging unit connected with the fingerprint collection unit, and a fingerprint database connected with the fingerprint imaging unit. The fingerprint collection unit is provided with a fingerprint analysis module for focusing on the collected fingerprints.

[0014] When collecting fingerprints, focus on the collected fingerprints through the fingerprint analysis module, and then image the collected fingerprints through the fingerprint imaging unit, compare the formed image with the data in the fingerprint database, and finally obtain the fingerprint comparison Conclusion of success or failure.

[0015] Since the fingerprint analysis module is set up to focus on the collected fingerprints, ideal fingerprint imaging can be obtained no matter in a dry or humid environment, which reduces the impact of the environment on fin...

Abstract

The invention relates to a self-adaptive fingerprint identification system which comprises a fingerprint acquisition unit. The fingerprint acquisition unit is provided with a fingerprint analysis module for carrying out focusing processing on an acquired fingerprint. According to the self-adaptive fingerprint identification system provided by the invention, the fingerprint analysis module is arranged for carrying out focusing processing on the acquired fingerprint, so that ideal fingerprint imaging can be ensured to be obtained, the influence of the environment on the fingerprint identification can be reduced, the accuracy of the fingerprint identification is improved and the false reject rate of inputting the fingerprint is reduced.

Description

technical field [0001] The invention relates to a fingerprint identification system. Background technique [0002] See attached figure 1 As shown, when the existing fingerprint identification system that cannot automatically adjust the dry humidity is in operation, the fingerprint is collected and imaged by the fingerprint acquisition unit, and the image is compared with the data in the fingerprint database, and then the success or failure of the comparison is obtained. recognition results. This fingerprint identification system is relatively affected by the weather. When the weather is dry, the recognition ability of the fingerprint is relatively poor, and the internal image is very light and blurred; while in the humid weather, the fingerprint recognition ability is strong, and the internal image is very thick, heavy, and blurry. Contents of the invention [0003] The purpose of the present invention is to provide an adaptive fingerprint identification system capable ...
