Title (EN) FINGERPRINT RECOGNITION METHOD AND RELATED PRODUCTS
(FR) PROCÉDÉ DE RECONNAISSANCE D'EMPREINTE DIGITALE ET PRODUITS ASSOCIÉ
Abstract:
(EN) Embodiments of the present disclosure provide a fingerprint recognition method and related products. The method may include: acquiring (201, 301) by the mobile terminal a first fingerprint image in a first fingerprint recognition mode; matching (202, 302) the first fingerprint image and a first enrolled fingerprint template; acquiring (204, 305) a second fingerprint image in a second fingerprint recognition mode, in response to detecting (203, 303) a number of consecutive occurrences of failure matching event; verifying (205, 306) whether the second fingerprint image is a valid fingerprint image; and determining (206, 307) that fingerprint is verified when the second fingerprint image is the valid fingerprint image.
(FR) Selon des modes de réalisation, la présente invention concerne un procédé de reconnaissance d'empreinte digitale et des produits associés. Le procédé peut comprendre : l'acquisition (201, 301), par le terminal mobile, d'une première image d'empreinte digitale dans un premier mode de reconnaissance d'empreinte digitale ; la mise en correspondance (202, 302) de la première image d'empreinte digitale et d'un premier modèle d'empreinte digitale enregistré ; l'acquisition (204, 305) d'une seconde image d'empreinte digitale dans un second mode de reconnaissance d'empreinte digitale, en réponse à la détection (203, 303) d'un certain nombre d'occurrences consécutives d'événement d'échec de mise en correspondance ; la vérification (205, 306) si la seconde image d'empreinte digitale est une image d'empreinte digitale valide ; et la détermination (206, 307) que l'empreinte digitale est vérifiée lorsque la seconde image d'empreinte digitale est l'image d'empreinte digitale valide.
