Ubuchwepheshe bokuhlonza iminwe ye-Fingerprint Scanner

Ukukhonjwa kweminwe kwesithwebuli somunwe, umsebenzisi udinga ukufaka kuphela ukufaka iminwe, i-module yomsebenzisi ekhipha izici zomunwe wokufaka, futhi uhlelo lufunda kaninginingi izici zeminwe yomunwe kanye nezici zeminwe yokufaka kusuka database ngokuya ngecebo elithile. Qondanisa kuze kube yilapho umunwe ongaqondanisa ngempumelelo ngempumelelo iminwe yokufaka yokufaka, bese ukhipha igama lomsebenzisi elihambisanayo, noma kuze kube yilapho kungekho minwe okufana neminwe yokufaka kungatholakala database, kuzokwenqatshwa iminwe, futhi inqubo yokuhlonza iminwe izothatha eyodwa noma izikhathi eziningi. Ukuqondanisa, ngokohlobo lwesigaba sokuhlonza, uhlelo lwe-othomathitho le-Fingerprint RJ luhlukaniswe ngohlelo lokuqinisekisa iminwe (noma olubizwa nge-1: 1 uhlelo) kanye nohlelo lokuhlonza iminwe.

Amapharamitha okusebenza wokuhlola uhlelo lokuhlonza umunwe oluzenzakalelayo ahlukaniswe izigaba ezintathu: Ukulungiswa kwamapharamitha, amapharamitha wesikhathi namapharamitha wesikhala. Amapharamitha asetshenziswa ngokujwayelekile afaka phakathi isilinganiso sokufanisa amaphutha, i-ERROR ARERIRTATCH STRING, amathuba okulingana, njll. Isikhathi sokubhalisa sichaza isivinini sohlelo, njengesikhathi sokubhalisa, njll. Amapharamitha wendawo ikakhulukazi abhekisela kwimemori eyabelwe Usayizi nosayizi wesici sethempulethi / j. Lapho uhlelo luhambisana neminwe emibili, bazothola izikolo zabo ezifanayo, ezingabhekwa njengokufana. Ngaphandle kokulahlekelwa yi-glue, ukufana kungabuye kuncishiswe ku [o, wena, ukusondelana okufanayo kimi, okufana kakhulu nalezi zinto zeminwe emibili, futhi okusondele kakhulu kufana nomehluko phakathi kweminwe emibili . Uma unikezwa umkhawulo wokufana f, uma amaphuzu afanayo inkulu kune- ', khona-ke iminwe emibili yahlulelwa ukuthi ifaniswe (ngaphandle kwalokho, uma kungenjalo iminwe efanayo), ngaphandle kwalokho iminwe emibili yahlulelwa ukuthi ifakwe yingakwenziwe (kusuka kuminwe ehlukene), Ngale ndlela, inani elifanayo elifanayo
.
. Imisebenzi ye) izoba nkulu, lapho u-6 encipha, okuphambene nalokho kuyiqiniso, ngoba i-DM: f (fmr), ngakho-ke c kungavezwa ngokuthi yi-FM, ngakho-ke susa u-R: 9 (*) = 8 (* F (Susa)) = H (FM MIN), khona-ke iShun ingumsebenzi we-MB.
Uma ukuxhumanisa okuvundlile kuthathwa njengokuxhumanisa okuvundlile, futhi ukuxhumanisa okuqondile kuthathwa njengokuxhumanisa okuqondile, kusungulwa uhlelo lokuxhumanisa izindiza. Lapho C kuthatha amanani ahlukile, sixhuma amaphuzu ohlelweni lokuxhumanisa <MR (') bese ususa u-R (c)) kwijika, le curve ijika le-roc kuya kokuvundlile I-Axis, ikhuphuka ukunemba kohlelo.
