Kodi magulu ang'onoang'ono a biometric pofikira njira zowongolera?

Ndondomeko ya kuzindikiridwa nthawi yodziwika bwino imakhala ndi microprocessor, gawo lodziwika bwino, gawo lamadzimadzi, lotchi kapena chip loko lakale, loko la magetsi. Microprocessor, monga kompyuta yapamwamba ya dongosololi, imalamulira dongosolo lonse. Chidziwitso cha chala ndi gawo limakwaniritsa zosonkhanitsa, kufanizira, kusungidwa, ndi kuchotsedwa kwa mawonekedwe a chala. Module yamadzimadzi yamadzi imagwiritsidwa ntchito posonyeza zidziwitso monga mbiri yotsegulira khomo, wotchi zenizeni ndi opaleshoni imalimbikitsa, ndikupanga mawonekedwe amakono ndi kiyibodi.

Chipangizo cha zala zowerengera (otola) amagwiritsa ntchito ukadaulo wa Phozelelelert kapena ukadaulo wapamwamba kuti atole nkhani zam'malo, ndiye kuti akupanga zidziwitso ndikuwafanizira ndi chidziwitso chosungidwa kuti mumalize chizindikiritso. Njirayi yonse imalizidwa mu chipangizo chowerengera, kapena chida chowerengera chimangotolera zala zam'manja, kenako ndikugawika ku zida zakumbuyo (monga PC) kuti mumalize kuchotsa. Chipangizocho chotola ndi zala zosiyanitsa ndi zala ndizosavuta kuchepera, zosavuta kugwiritsa ntchito, ndipo kuthamanga kwa dongosololi kumathamanganso. Kusonkhanitsa zinthu zala zala kumafunikira kukhazikitsidwa kwa ubale womwe watchulidwa pakati pa chala cha munthu ndi osonkhanitsa pakugwira ntchito. Chifukwa chake, kachitidwe kali ndi chidwi.
Biostatatic Lili ikuwonetsa kuti zala zam'manja zimakhala ndi mwayi wapamwamba kwambiri, ndipo kuthekera kwa zomwe zalembedwa pakati pa anthu ndizochepa kwambiri, chifukwa chotetezedwa kwambiri, koma pali chilimbikitso chomenyedwa. Chifukwa chake, zopangidwa ndi ntchito ya zokhala ndi zam'manja zawonekera, makamaka kuti ziwonjezere kutentha kwa kutentha, kukwezedwa, ndi michere kuti zitsimikizire kuti zotsimikizika za zala zomwe zasonkhanitsidwa. Kuti mupeze dongosolo lolowera ndi zofuna za chitetezo, kuwonjezera pa kupezeka kwa zala ndi kupezeka kwa nthawi, njira zina zowonjezera, njira monga malembawo, ziyenera kuwonjezeredwa kukonza chitetezo chamapumu.
1. Palm Revied Reference Propect
Zomwe zili mu Palprirint ndizolemera, ndipo munthu akhoza kutsimikiza kwathunthu pogwiritsa ntchito mzere, mfundo, mawonekedwe, komanso mawonekedwe a geometric a palmprint. Maziko a nthawi yodziwika bwino ya kanjedza ndi kuzindikiridwa kwa kanjedza. Kuzindikira kwa kanjedza ndikuzindikira mikhalidwe ya kanjedza ndi zala zam'manja, ndipo zinthu zapamwamba zimatha kuzindikira zithunzi zamitundu itatu.
Kuzindikira kwa kanjedza ndikosavuta kugwiritsa ntchito. Ndioyenera kuchitika ndi ogwiritsa ntchito ambiri kapena kuvomereza kosavuta, ndipo kulondola kwake ndikokwera kwambiri. Osakwana 1 sekondi, kudziwika kwa wogwiritsa ntchito kumatsimikiziridwa ndikuwona mawonekedwe a magawo atatu monga kukula kwake, motero ndikuwonetsetsa kuti antchito okhaokha alowe m'malo ena, choncho zokwaniritsa cholinga cholowera. Monga njira ina ku radio fraquency Card yolowera, njira yoyendetsera magy imathandizira ogwiritsa ntchito kuti asunge mtengo wogwiritsira ntchito ndi kugwiritsa ntchito makadi ena kuti awonjezere chitetezo. Poyerekeza ndi dongosolo la zala la zala, dongosolo lozindikira la lal hand lili ndi dothi ndi zipsera zomwe sizikukhudza muyeso, ndipo dzanja ndilosavuta kuyika pamalo oyenera a scanner, etc., zomwe ndizosavuta kuti ogwiritsa ntchito avomereze.
2. Makina oyang'anira
Njira yodziwitsa iris iris ndikuzindikira kuti ndife anthu ndikuwona ngati mungatsegule chitseko poyerekeza chithunzi cha Iris chithunzi. Njira yaukadaulo wodziwika bwino limaphatikizaponso masitepe anayi: imodzi ndikugwiritsa ntchito zida zapadera za kamera kuti iwombeni maso a anthu, pezani zithunzi za Iris ndikuzitumiza ku fano lomwe limakonzedwa ku Iris. Lachiwiri ndikupeza IRIIS, onani malo amkati mwamkati, bwalo lakunja ndi mapiko okhazikika m'chifaniziro; Sinthani kukula kwa iris m'chithunzichi ku dongosolo la madongosolo, ndiye kuti, gwiritsani ntchito mawonekedwe. Chachitatu ndikutengera algorithm inayake kuti ichotse mfundo zofunika kwambiri pa chithunzi cha iris ku Iris ndikuziyika. Chachinayi ndikugwirizana ndi ma code omwe amapezeka ndikuchotsa chithunzi cha iris ku IRIS mu dalabase imodzi yodziwika ndi munthu kuti aweruze ngati ali iris. Njira yodziwitsa iris iris sikutanthauza kulumikizana kwakuthupi, imakhala ndi chizindikiritso chochepa chabodza komanso kudalirika kwambiri; Komabe, ndizovuta kupirira zida zomaliza za kutsogolo, mtengo wake ndi wokwera, ndipo ndizovuta kupititsa patsogolo pamlingo waukulu.
3. Kuzindikira kwa Pamaso Kufikira
Poyerekeza ndi matekinoloje ena achidziwitso omwe amapezeka pamadera opezeka kumaso amapezeka apadera pakufunsidwa, mwachitsanzo, ndi yosavuta pakuwerengera zithunzi, ndipo pang'onopang'ono akhala mtundu wachilengedwe kwambiri komanso wachilengedwe wa biometric kuzindikira. Cholinga cha luntha ndi kuvomerezedwa zimagwiritsidwanso ntchito kwambiri pamachitidwe olamulira.
Njira yodziwitsa nkhope yomwe imapezeka nthawi yolowera imasonkhanitsa zidziwitso za anthu onse omwe amaloledwa kupeza njira yolowera ndikuyisunga pamalo osungira. Munthu akapeza njira yolowera kuwongolera, njira yodziwika bwino yolowera imayamba kupeza zidziwitso kudzera mu kamera, kenako ikani chithunzi chomwe chophatikizira pakompyuta, kenako nkuchita nawo zowona. Munjira iyi, kachitidwe ka alendo kazithunzithunzi kuti mupewe kufotokozera, zowunikira ndi zida zowonjezera pazomwe zidakonzedwa, ndikulemba zomwe zatulutsidwa ndi chidziwitso cha nkhope, ndipo Lembani zotsatira zodziwika. Chidziwitso cha nkhope zomwe zitha kufananizidwa molinganizidwa mu database, makina oyendetsera pulogalamuyi alandire malangizo apakompyuta, ndipo kugwiritsidwa ntchito kwa alendo kuti akhazikitsidwe Kupanda kutero, kompyuta sidzapereka malangizo otsegula chitseko, ndipo kuwongolera dongosolo sikudzatsegulidwa, ndipo chidziwitso cha mlendoyo chidzajambulidwa kwa kufunsa komanso kuyang'aniridwa.
