Fingerprint scanner system zvikamu

Kune akawanda marudzi emunwe eminwe scanner, uye pakati pemhando idzi, zvigunwe zvigunwe zvigunwe zvinoshandiswa zvakanyanya. Zvigunwe zvevanhu zvakasarudzika uye kuramba zvisina kuchinjika muhupenyu hwese. Kusunungurwa zvigunwe kunokosha nyore uye kwakachengeteka. Saka zvikamu zvipi zvinozivikanwa nenzvimbo dzinochengetwa munweve? Zvitaure nezvazvo nemupepeti.

1. Fingerprint mufananidzo compression
Yakakura-kugona zvigunwe zvigunwe zvigunwe zvinofanirwa kumanikidzwa uye kuchengetwa kuti uderedze nzvimbo yekuchengetedza. Nzira huru dzinosanganisira Jpeg, Wsq, ZW, nezvimwe.
2. zvigunwe zvigunwe mifananidzo yekugadzirisa
Kusanganisira zvigunwe zvigunwe zvekuona, mufananidzo wemhando yekutonga, mafambiro uye kuwanda kwemifananidzo, etcupprint ruzivo rwakakurumbira. Chinangwa chayo ndechekuvandudza mhando yemifananidzo yeminwe uye kugadzirisa chokwadi chehurongwa hwekubvisa. Kazhinji, maitiro ekutanga anosanganisira kujairika, chikamu chechifananidzo, kuvandudza, binarization, uye matanho ekutakura, asi matanho ekurega akasiyana zvichienderana nemamiriro ezvinhu chaiwo.
3. Fingerprint Inoratidza Kubvisa
Fingerprint Inoratidza Kubvisa: Bvisa zvigunwe zvigunwe chimiro chechinyorwa ruzivo kubva pamufananidzo wakakwana. Ruzivo rwacho runonyanya kusanganisira parameter dzakadai serudzi, runoronga, uye kutungamira. Zvinyorwa zvakadzama muminwe zvinowanzo kusanganisira endpoints, mapoinzi ezvipfuyo, mapoinzi ezvipfuyo, etcomputation uye etpurcation mapoinzi emitsetse anoonekwa kazhinji mune zvigunwe, uye zviri nyore, uye zviri nyore kuwana. Aya marudzi maviri ezvinyorwa zvinhu anogona kuenderana nezvimiro zvigunwe zvechigunwe
4. zvigunwe zvigunwe
Fingerprint kuenzanisa maitiro emunwe wechigunwe kunounganidzwa pane saiti ine hunhu hwemunwe hwakachengetedzwa mumunwe wechigunwe database kuti uone kana vari vechigunwe zvakafanana. Pane nzira mbiri dzekuenzanisa zvigunwe zvigunwe:
① Imwe-kune-imwe yekuenzanisa yemugunwe yemushandisi kuti ifananiswe kubva kuFinerprint Database yakavakirwa pane mushandisi ID, wobva waenzanisa neyechangobva kuunganidzwa zvigunwe;
② Imwe-kune-yakawanda enzaniso: Enzanisa iyo ichangobva kuunganidzwa zvigunwe zvemunwe mumwe nemumwe neese zvigunwe zvigunwe mumugunwe mumunwe wechigunwe database.
Nekuvandudzwa kwesainzi uye tekinoroji munyika medu, kupindirana kweminwe nguva yekunakidzwa kune huwandu hwakawanda hwekushandisa, kunyanya mukudzora uye kupinda. Uye mutengo wakaderera, vazhinji vashandisi vanogamuchira iyi tekinoroji.
