Abstract

A biometric feature identification method and device, the biometric feature identification method includes: acquiring pressure information accompanied by biometric feature input; calculating biometric feature collection parameters according to the pressure information; collecting biometric feature information under the biometric feature collection parameters; The collected biometric information is used to identify biometrics. By combining the pressure information to calculate biometric acquisition parameters, the number of iterations of biometric acquisition can be reduced, thereby reducing the time required for biometric detection.

Description

technical field [0001] The present disclosure relates to the field of biological feature identification, and in particular to a biological feature identification method and device. Background technique [0002] With the development of technology, biometric identification technologies such as fingerprints, palm prints, faces, and irises are increasingly used in various fields, and the requirements for the speed and accuracy of biometric identification are also getting higher and higher. Taking fingerprint identification as an example, when the same finger presses the fingerprint sensor with different pressures, the contrast between the fingerprint ridge and the fingerprint valley in the fingerprint image is different, so it is necessary to adjust the fingerprint acquisition parameters several times, and after each adjustment of the fingerprint acquisition parameters, it is necessary to re- Fingerprint acquisition is performed until a fingerprint image with the desired contras...
