FINGERPRINT RECOGNITION METHOD AND APPARATUS

Abstract: a fingerprint recognition method and apparatus are provided. the method is applied to the field of fingerprint recognition technologies. the method includes: when a first fingerprint image is successfully matched, judging whether matching information of the first fingerprint image satisfies a first preset condition; when the matching information of the first fingerprint image satisfies the first preset condition, judging whether a cumulative update count of a second fingerprint template is greater than a first quantity threshold; when the cumulative update count of the second fingerprint template is greater than the first quantity threshold, judging whether priority information of the second fingerprint template satisfies a second preset condition; and when the priority information of the second fingerprint template satisfies the second preset condition, updating the second fingerprint template with the first fingerprint image. a high-quality fingerprint image is selected through a plurality of judgment conditions to update a fingerprint template library. matching is performed based on an updated fingerprint template library. this can increase a fingerprint unlocking rate and an unlocking speed, so that user experience in unlocking is improved.
