Fingerprint Scanner Nheyo uye Algorithm

Iyo yemunwe scanner inotsiva kiyi yechinyakare nemunwe wako. Paunenge uchishandisa iyo, iwe unongoda kuisa chigunwe chako flat pane yekuunganidza hwindo rechigunwe yemunwe wechiScanner kupedzisa basa rekusunungura. Iko kuvhiya kuri nyore uye kunzvenga mukana wekunyepedzera, kuba, uye kukanganwa mune mamwe masisitimu ekudzora, kutsausa uye zvimwe zvisina kunaka. Saka, yakawanda sei iwe yaunoziva iwe nezveMinwe yekuziva nguva yekuziva nguva uye algorithms.

Isu tinoziva kuti zvigunwe zvemunwe zvakasarudzika. Uku kusarudzika kunoreva chaizvo kuti zvigunwe zvemunhu wese zvakasiyana. Uku kusarudzika ndiyo nheyo yekushandisa zvigunwe zvekusiyanisa vanhu vakasiyana. Chinangwa chekutanga kwekunyepedzera kwekunyengera nguva ndeyekuti ndiani anogona kupinda muhurongwa uye asingakwanise kupinda muchivako, uye kupa mvumo dzakasiyana kune vashandisi vakasiyana. Pfungwa yayo yekutanga ndeyekuwana chigunwe chemunwe wemushandisi kuti abatwe mukati, uye fananidza chigunwe nemunwe neminwe yeminwe yevashandisi vese vashandisi pre-yakanyorwa mu data. Mutambo wakabudirira unoratidza kuti mushandisi ari mushandisi wepamutemo uye anobvumidzwa zvinoenderana nerondedzero yemvumo mu data. Zvikasadaro, hazvisi pamutemo. mushandisi, uye kudzivirira mushandisi kubva mukupinda, nokudaro anoziva manejimendi emunhu wechivako. Matanho mana anotevera anoshandiswa kuona mifananidzo dzakasiyana zvifananidzo, uye kuedza kwakaratidza kuti nzira iyi ine mhedzisiro inozivikanwa iri nani:
1) Shandisa chigunwe chemubatanidzwa kuti uwane mugunwe yemubatanidzwa.
2) Preprocessing of Fingerprint Mifananidzo: Mifananidzo yakawanikwa nemutero wemunwe munharaunda isinganyanye kusanganiswa neruzha, uye idzi ruzha ruzha runokanganisa chinhanho chinotevera chekuzivikanwa. Maitiro ekutanga pano ndekuchinja mifananidzo yakaunganidzwa mune yakanyanya kukodzera. Ziva mifananidzo. Nzira huru yekugadzirisa inosanganisira: kuwedzeredza mufananidzo, mufananidzo unoridza, kufananidzira, binarization, nezvimwe.
3. Zvimiro zvakakosha kusiyanisa akasiyana zvifananidzo zvifananidzo. Kuzivikanwa kweminwe uye kufananidza zvakavakirwa pachigadzirwa. Chinhu chakanaka chinongedzo nzira inosarudza nzira yekuziva yakazivikanwa kune yakakura. Pano isu tinoshandisa marongero uye kutungamira munda wemubatanidzwa wemunwe wechifananidzo chiratidzo seyekupedzisira ficha vector, uye shandisa ichi chimiro kuratidza uye kusiyanisa vashandisi vakasiyana.
4) Mufananidzo wemifananidzo Kuti uwedzere kusimudzira kusimba kwemunwe wemunwe, idzo dzechiratidzo dzechikamu pfungwa dzakashandurwa muPolar radius, polar angle uye minda yepolar yakaunganidzwa. Iyo inoshanduka yekusunga bhokisi nzira inoshandiswa kururamisa iyo isipoler deformation uye misiyano misiyano yakagadzirwa panguva yekuwana kwemifananidzo.
Systems Kudzora Systems inowanzo kuve nevanodzora, vaverengi vekadhi, madhiri ekuvhura, makomputa (makomputa), maneja ekutaurirana, maneja ekutaurirana, manejimendi, etc. pane iyi. , iyi mapepa anogadzirwa gadziriso yekudzora yekudzora yakavakirwa pachigadziko cheminwe. Dhizaini yehurongwa hwese inogona kukamurwa muzvikamu zvepanyama network module yeiyo yekuwana yekudzora system uye iyo inozivikanwa nguva yekuziva nguva yekuvapo kwechokwadi. Iyo Network network module inosanganisira chimiro chemuviri weiyo yekudzora yekudzora uye michina, nepo mwero wechiitiko chechiitiko chinonyanya kusanganisira dhizaini uye kusimudzwa kwe software uye kugadzwa yemvumo yeMushandisi yemugunwe yemugunwe, iyo inoitwa kuburikidza neiyi software yekuvimbika yemugunwe emushandisi.
Iyo yese zvigunwe zvigunwe chokwadi algorithm system inogamuchira dhizaini yehukama uye yakakamurwa kuita matatu matatu. Iyo yepasi denderedzwa inosanganisira iyo data tafura yemufananidzo, iyo Classifier module uye iyo template zvigunwe zvigunwe raibhurari; Iyo yepakati layer ndiyo interface layer, kusanganisira iyo ficha yekubvisa interface, inoratidzika kufananidza interface uye zvigunwe zvigunwe database inoshanda? Iyo yekumusoro denderedzwa ndeyekunyorera kwechikumbiro, kusanganisira zvigunwe zvekunyoresa zvigunwe, zvigunwe zvigunwe, chigunwe zvigunwe zvigunwe uye zvigunwe zvigunwe uye zvigunwe database manejimendi.
Iyi module yekutanga inobvisa iyo Fingerprint mufananidzo data Mune yekudzora kwekutonga, hunhu hwemunwe wemunun'una wemubatanidzwa wemubatanidzwa unowanikwa kuburikidza nemuteresi, uye kuenderana nedata mudhata kuti uone kana mushandisi akatenderwa kupinda.
