Kuzivikanwa kwemunwe unoziva sei nguva yekubatira

April 10, 2023

Chiziviso chigunwe chiri parizvino ndiyo nzira inonyanya kushandiswa nzira yekunakidzwa kweminwe. Kuvhara mukati nekubuda mubasa, kuvhura foni, kuvhura musuwo, nezvimwe saka basa rekuziva zvigunwe zvigunwe zvigunwe zvigunwe zvigunwe zvinozivikanwa zvinozivikanwa?

How Is The Fingerprint Recognition Time Attendance Function Realized Is It Possible For Fingerprints To Be Copied

Nekukura kwekuenderera uye kukura kweminwe yekuziva zvigunwe nguva yekunyepedzera, mikova yekukiya inoshandisawo zvigunwe zvigunwe zvekunzwa. Kubva ipapo, kupinda kwehungwaru kwemunwe wekunakidzwa kwekupinda nguva. Smart Door Lock inovandudza zvakanyanya kuchengetedzeka uye kuve nyore kwemusuwo kukiya kuburikidza nekushandiswa kwemabasa ekuziva zvigunwe. Iko kuzivikanwa kweminwe kunozivikanwa sei kwekunakidzwa kwekuziva zvizere nguva
Iyo inonzi minererprirt inoreva mitsara pamusoro peiyo yemunwe wemuviri wemunhu. Chiziviso chigunwe chinonyanya kuve neinotevera matatu maitiro:
1. Fingerprint Kuwedzera
Mukuita kwekuunganidza zvigunwe zvigunwe, nekuda kwezvikonzero zvakasiyana, zvakaunganidzwa zvigunwe zvigunwe zvisingaonekwe neruzha, kana zvakashandiswa zvakanyatso kuzivikanwa zviziviso zviziviso, zvinowanzoitika kuti uwane mhedzisiro. Naizvozvo, isu tinogona kuvandudza iyo Fingerprint mufananidzo mhando kuburikidza neimwe logy inomisikidza maitiro ekuwedzera. Maitiro ayo achashandiswa pano anosanganisira chikamu chechifananidzo, Halfox kuenzaniswa, kuwedzerwa kwefaira, binarization, kuonda, etc.
2. Ratidza Exction
Chigunwe chigunwe chiratidzo chebenzi chemuviri wemunhu, icho "chakasiyana" uye "chisiri chinodzokororwa". Kupinda kweminwe yekuzivikanwa kweminwe kunofananidza zvigunwe zvigunwe mukushandisa zvakajairika mushure mekuungana.
3. Fingerprint inoenderana
Kune marudzi mazhinji emunwe wemunwe unoenderana neAlgorithms Nongedzera nzira yekufananidza ndeyekufananidza iyo inobviswa minutiae point yakaiswa pamwe neinatiae point yakaiswa mune database. Kana iyo poindi yakagadzika mutambo kuburikidza nekuenderera mberi, scashanduko uye shanduro yekushandura, ipapo mifananidzo miviri yeminwe inoenderana.
Iko kune kunyanya nzira mbiri dzekuziva iyo Fingerprint Kuziva Nguva Yekupinda Basa Rekuita:
1. rarama zvigunwe zvigunwe
Izvo zvinongoita kune kuzivikanwa kweminwe yehupenyu hwevanhu chaivo, uye hauzive zvimwe zvinhu zvese, izvo zvinogona kusiyanisa zvigunwe zvechokwadi uye zvinyepedzera zvigunwe zvenhema. Kazhinji, tinogona kuita izvi nekushandisa Semiconductor Fingerprint yekuziva nguva yekuziva nguva.
2. Optical yemunwe eminwe yekuziva nguva yekuenda
Iko kuzivikanwa chaiko kwekunakidzwa kwekunakidzwa kwekunakidzwa kwekunakidzwa kwekunakidzwa kwenguva yekutanga yemunwe. Zvichienderana nechiedza chakaburitswa nechinhu chechiitiko chechiitiko, chakaburitswa pamunwe uye wobva waratidza kumashure kumushini kuti uwane data, uye uchienzaniswa nedatabase kuti uone kana ichienderana.
