I-biometrics yimilinganiselo yomzimba kunye nezibalo ezinxulumene neempawu zomntu. Ungqinisiso lwebhayometriki (okanye ungqinisiso oluyinyani) lusetyenziswa kwisayensi yekhompyuter njengohlobo lokuchongwa kunye nolawulo lokufikelela. Ikwasetyenziselwa ukuchonga abantu abakumaqela aphantsi kweliso elibukhali.

Izazisi zebhayometriki zezona mpawu zihlukileyo, ezinokulinganiswa ezisetyenziselwa ukuleyibhelisha nokuchaza umntu ngamnye. Izazisi zebhayometriki zihlala zihlelwa njengeempawu zefiziyoloji ezinxulumene nokumila komzimba. Imizekelo ibandakanya, kodwa ayiphelelanga kwiminwe yeminwe, imithambo yesundu, ukubonwa kobuso, iDNA, ukuprintwa kwesundu, ijometri yesandla, ukuqaphela iris, iretina, kunye nevumba/ivumba.

Itekhnoloji yokuchonga yebhayometriki ibandakanya isayensi yekhompyuter, i-optics kunye ne-acoustics kunye nezinye isayensi yendalo, isayensi yebhayoloji, i-biosensors kunye nemigaqo ye-biostatistics, itekhnoloji yokhuseleko, kunye netekhnoloji yobukrelekrele bokwenziwa kunye nezinye iisayensi ezininzi ezisisiseko kunye nobuchwepheshe bokusebenzisa obutsha. Zizisombululo zobugcisa ezipheleleyo ze-multidisciplinary.

Kwiminyaka yakutshanje, ngophuhliso lobukrelekrele bokwenziwa, itekhnoloji yokuchongwa kwebhayometriki iye yakhula ngakumbi. Okwangoku, itekhnoloji yokuqaphela ubuso yeyona imele i-biometrics.

Ukuqaphela ubuso

Inkqubo yokuqondwa kobuso ibandakanya ukuqokelelwa kobuso, ukubonwa kobuso, ukutsalwa kweempawu zobuso kunye nokuqondwa kokulinganisa ubuso. Inkqubo yokuqaphela ubuso isebenzisa itekhnoloji eyahlukeneyo efana ne-AdaBoos algorithm, i-convolutional neural network kunye nomatshini we-vector wenkxaso ekufundeni koomatshini.

Inkqubo yokuqaphela ubuso

Okwangoku, ubunzima bokuqonda ubuso bendabuko obubandakanya ukujikeleza kobuso, ukuvalela, ukufana, njl., kuphuculwe kakhulu, okuphucula kakhulu ukuchaneka kokuqaphela ubuso. Ubuso be-2D, ubuso be-3D, ubuso obuninzi be-spectral Imowudi nganye ineemeko ezahlukeneyo zokufumana ukulungelelaniswa, idigri yokhuseleko lwedatha kunye nobuntununtunu babucala, njl. Iyakwazi ukuchonga ngokukhawuleza isazisi somntu, nto leyo eye yazisa impumelelo ethile ekusetyenzisweni kokuqondwa kobuso obunamacala amabini.

Kwangaxeshanye, itekhnoloji yokufumanisa i-biometric ngoku isetyenziswa njengetekhnoloji ephambili yokuphucula ukhuseleko lokuqondwa kobuso, obunokuthi buxhathise ngokufanelekileyo ubuqhetseba bomgunyathi obunje ngeefoto, iividiyo, iimodeli ze-3D, kunye neemaski ezifakelweyo, kunye nokuzimela ngokuzimeleyo ukuba ngubani. abasebenzisi abasebenzayo. Okwangoku, ngophuhliso olukhawulezayo lwetekhnoloji yokuqonda ubuso, uninzi lwezicelo ezintsha ezinje ngezixhobo ezihlakaniphileyo, imali ye-intanethi, kunye nentlawulo yobuso ziye zanda kakhulu, zizisa isantya kunye nokulula kubomi kunye nomsebenzi womntu wonke.

Palmprint ukuqatshelwa

Ukuqaphela iPalmprint luhlobo olutsha lwetekhnoloji yokuqaphela i-biometric, esebenzisa i-palmprint yomzimba womntu njengeyona nto ijoliswe kuyo, kwaye iqokelela ulwazi lwebhayoloji ngetekhnoloji ye-imaging multispectral. Ukuqaphela i-multi-spectral palmprint inokuthathwa njengomzekelo we-biometric recognition technology edibanisa i-multi-modality kunye neempawu ezininzi ezijoliswe kuzo. Ubuchwephesha obutsha budibanisa iimpawu ezintathu ezichongiweyo zolusu, ukuprintwa kwesundu kunye nemithambo yemithambo ukunika ulwazi oluninzi ngexesha elinye kunye nokwandisa ukwahlula kweempawu ekujoliswe kuzo.

Kulo nyaka, itekhnoloji yokwamkelwa kwesundu yaseAmazon, ebizwa ngokuba yi-Orville, sele iqalile ukuvavanywa. I-scanner kuqala ifumana isethi yemifanekiso ye-infrared polarized original, igxininise kwiimpawu zangaphandle zesundu, njengemigca kunye nokugoba; xa ufumana iseti yesibini yemifanekiso yepolarized kwakhona, igxininisa kwisakhiwo sesundu kunye neempawu zangaphakathi, njengemithambo, amathambo, izicubu ezithambileyo, njl njl. Le mifanekiso ikhanya kakuhle, igxininise, kwaye ibonise intende kwi-orientation ethile, kwi-pose ethile, kwaye ibhalwe njengesandla sasekhohlo okanye sokunene.

Okwangoku, itekhnoloji yokuqaphela i-palmprint ye-Amazon inokuqinisekisa ubuwena kunye nentlawulo epheleleyo nge-300 milliseconds kuphela, kwaye ayifuni ukuba abasebenzisi babeke izandla zabo kwisixhobo sokuskena, vele ushukumise kwaye uskene ngaphandle koqhagamshelwano. Izinga lokungaphumeleli kobu buchwepheshe malunga ne-0.0001%. Ngexesha elifanayo, ukuqaphela i-palmprint kukuqinisekiswa kabini kwinqanaba lokuqala - okokuqala ukufumana iimpawu zangaphandle, kwaye okwesibini ukufumana iimpawu zentlangano zangaphakathi. Xa kuthelekiswa nobunye ubugcisa bebhayometriki ngokwemiqathango yokhuseleko, iphuculwe.

Ukongeza kwezi mpawu zebhayometriki zingentla, itekhnoloji yokuqaphela iris nayo iyathandwa. Izinga lokuqaphela ubuxoki bokuqatshelwa kwe-iris liphantsi njenge-1/1000000. Ikakhulu isebenzisa iimpawu zokungaguquguquki kobomi be-iris kunye nokwahlukana ukuchonga izazisi.

Okwangoku, ukuvumelana kwishishini kukuba ukuqatshelwa kwendlela enye kunezithintelo ekusebenzeni kokuqaphela kunye nokhuseleko, kunye ne-multi-modal fusion yinkqubela ebalulekileyo ekuqapheliseni ubuso kunye nokuqaphela i-biometric-kungekhona kuphela kwizinto ezininzi. ukuphucula ukuchaneka kokuqondwa kunokuphucula ukuziqhelanisa nendawo kunye nokhuseleko lwabucala lobuchwepheshe bebhayometriki ukuya kumlinganiselo othile. Xa kuthelekiswa ne-algorithm yendlela enye yemveli, inokuhlangabezana ngcono nezinga lokuqondwa kobuxoki kwinqanaba lemali (elisezantsi njengenye kwizigidi ezilishumi), ekwayindlela ephambili yophuhliso lokuchongwa kwebhayometriki.

Inkqubo yebhayometriki ye-Multimodal

Iinkqubo zebhayometriki ezininzi zisebenzisa i-sensor ezininzi okanye i-biometrics ukoyisa imida ye-unimodal biometric systems.Ngokomzekelo, ii-iris recognition systems zingathotywa yi-irises egugayo kwaye ukuqondwa kweminwe ye-elektroniki kunokwenziwa mandundu ngokuguga okanye ukunqunyulwa kweminwe. Ngelixa iisistim zebhayometriki ezingafaniyo zisikelwe umda yimfezeko yesazisi, akunakwenzeka ukuba iinkqubo ezininzi ze-unimodal ziya kuchaphazeleka yimida efanayo. Iisistim zebhayometriki ye-Multimodal zinokufumana iiseti zolwazi kwisiphawuli esifanayo (oko kukuthi, imifanekiso emininzi ye-iris, okanye iskena somnwe omnye) okanye ulwazi oluvela kwi-biometrics eyahlukeneyo (ifuna iskeni seminwe kunye, kusetyenziswa ukuqondwa kwelizwi, ikhowudi yokudlula ethethiweyo).

Iinkqubo zebhayometriki ye-Multimodal zinokudibanisa ezi zixokelelwano ze-unimodal ngokulandelelanayo, ngaxeshanye, indibaniselwano yazo, okanye kuthotho, ezibhekiselele kwiimowudi ezilandelelanayo, ezinxuseneyo, zenqanaba eliphezulu kunye nezilandelelanayo, ngokulandelelanayo.

ICHANCCTVuphuhlise uthotho lweiilensi zebhayometrikiukuqondwa kobuso, ukuqondwa kwepalmprint kunye nokuchongwa kweminwe kunye nokuchongwa kweiris.Umzekelo CH3659A yi-4k low distortion lens eyilelwe i-1/1.8'' yoluvo. Ifaka yonke iglasi kunye noyilo oludibeneyo kunye ne-11.95mm TTL kuphela. Ibamba i-44 degrees kwindawo ethe tyaba yokujonga. Le lens ilungele ukuqatshelwa kwe-palmprint.
