I-Biometrics zizilinganiso zomzimba kunye nokubala okunxulumene neempawu zomntu. Ukuqinisekiswa kwe-biometric (okanye ukuqinisekiswa okuyinyani) kusetyenziswa kwisayensi yekhompyutha njengendlela yokuchonga kunye nokulawula ukufikelela. Ikwasetyenziselwa ukuchonga abantu kumaqela aphantsi kweliso.

Iimpawu zebhayomethrikhi ziimpawu ezikhethekileyo nezilinganiswayo ezisetyenziselwa ukulebhelisha nokuchaza abantu ngabanye. Iimpawu zebhayomethrikhi zihlala zihlelwa njengeempawu zomzimba ezinxulumene nokuma komzimba. Imizekelo ibandakanya, kodwa ayipheleli nje kwiminwe, imithambo yesundu, ukuqondwa kobuso, i-DNA, ushicilelo lwesundu, ijiyometri yesandla, ukuqondwa kwe-iris, i-retina, kunye nevumba/ivumba.

Itekhnoloji yokuchonga i-biometric ibandakanya isayensi yekhompyutha, i-optics kunye ne-acoustics kunye nezinye iisayensi zefiziksi, isayensi yebhayoloji, imigaqo ye-biosensors kunye ne-biostatistics, itekhnoloji yokhuseleko, kunye netekhnoloji yobukrelekrele bokwenziwa kunye nezinye iisayensi ezisisiseko kunye neetekhnoloji ezintsha zesicelo. Sisisombululo sobugcisa esipheleleyo esinamacandelo amaninzi.

Kwiminyaka yakutshanje, ngophuhliso lobukrelekrele bokwenziwa, iteknoloji yokuchonga i-biometric iye yakhula ngakumbi. Okwangoku, iteknoloji yokuqonda ubuso yeyona imele kakhulu i-biometrics.

Ukuqaphela ubuso

Inkqubo yokuqaphela ubuso ibandakanya ukuqokelelwa kobuso, ukubonwa kobuso, ukukhupha iimpawu zobuso kunye nokubonwa kobuso obufanayo. Inkqubo yokuqaphela ubuso isebenzisa ubuchwepheshe obahlukeneyo obufana ne-AdaBoos algorithm, inethiwekhi ye-convolutional neural kunye nomatshini we-support vector ekufundeni koomatshini.

Inkqubo yokuqaphela ubuso

Okwangoku, ubunzima bokuqaphela ubuso bendabuko kuquka ukujikeleza kobuso, ukuvaleka, ukufana, njl.njl. buphuculwe kakhulu, nto leyo ephucula kakhulu ukuchaneka kokuqaphela ubuso. Ubuso be-2D, ubuso be-3D, ubuso be-multi-spectral. Imo nganye ineemeko ezahlukeneyo zokulungelelanisa ukufunyanwa, inqanaba lokhuseleko lwedatha kunye nobuntununtunu babucala, njl.njl., kwaye ukongezwa kokufunda nzulu kwedatha enkulu kwenza i-algorithm yokuqaphela ubuso be-3D yongeze iziphene ze-2D projection, Ingachonga ngokukhawuleza ubuwena bomntu, nto leyo eye yazisa impumelelo ethile ekusetyenzisweni kokuchongwa kobuso obunemilinganiselo emibini.

Kwangaxeshanye, iteknoloji yokuchonga ubuso ngoku isetyenziswa njengeteknoloji ephambili yokuphucula ukhuseleko lokubona ubuso, enokumelana ngempumelelo nobuqhetseba bokukhohlisa obufana neefoto, iividiyo, iimodeli ze-3D, kunye neemaski zokufakelwa, kwaye ikwazi ukuchonga ngokuzimeleyo ubuwena babasebenzisi abasebenzayo. Okwangoku, ngophuhliso olukhawulezileyo lwetekhnoloji yokuqonda ubuso, usetyenziso oluninzi olutsha olufana nezixhobo ezikrelekrele, imali-mboleko ye-intanethi, kunye nentlawulo yobuso ziye zathandwa kakhulu, zizisa isantya kunye nokulula kubomi bomntu wonke kunye nomsebenzi.

Ukuqatshelwa kweMifanekiso yesandla

Ukuqatshelwa kwesandla sesandla luhlobo olutsha lobuchwepheshe bokuqatshelwa kwebhayomethrikhi, olusebenzisa i-palmprint yomzimba womntu njengophawu olujoliswe kulo, kwaye luqokelela ulwazi lwebhayoloji ngetekhnoloji yokufota nge-multispectral. Ukuqatshelwa kwesandla sesandla se-multi-spectral kunokubonwa njengomzekelo wetekhnoloji yokwazi i-biometric edibanisa i-multi-modality kunye ne-multi-target features. Le teknoloji intsha idibanisa iimpawu ezintathu ezichongiweyo ze-skin spectrum, i-palm print kunye ne-vein veins ukubonelela ngolwazi oluninzi ngexesha elinye kunye nokwandisa ukwahluka kweempawu ezijoliswe kuzo.

Kulo nyaka, iteknoloji yokuqaphela iintende zesandla yeAmazon, ebizwa ngokuba yi-Orville, iqalile ukuvavanya. Iskena kuqala sifumana iseti yemifanekiso yokuqala ene-infrared polarized, sigxile kwiimpawu zangaphandle zesundu, njengemigca kunye nokugoba; xa sifumana iseti yesibini yemifanekiso ene-polarized kwakhona, sigxila kwisakhiwo sesundu kunye neempawu zangaphakathi, njengemithambo, amathambo, izicubu ezithambileyo, njl. Imifanekiso eluhlaza iqale icutshungulwe ukuze inike iseti yemifanekiso equlethe izandla. Le mifanekiso ikhanyiswe kakuhle, igxile, kwaye ibonisa intende kwi-orientation ethile, kwi-pose ethile, kwaye ibhalwe njengesandla sasekhohlo okanye sasekunene.

Okwangoku, iteknoloji yokuqaphela imifanekiso yesandla yeAmazon inokuqinisekisa ubuwena bomntu kunye nentlawulo epheleleyo kwi-300 milliseconds kuphela, kwaye ayifuni ukuba abasebenzisi babeke izandla zabo kwisixhobo sokuskena, bamane bashukumise kwaye baskene ngaphandle kokunxibelelana. Izinga lokusilela kwale teknoloji limalunga ne-0.0001%. Kwangaxeshanye, ukuqaphela imifanekiso yesandla kukuqinisekiswa kabini kwinqanaba lokuqala - okokuqala ukufumana iimpawu zangaphandle, kwaye okwesibini ukufumana iimpawu zangaphakathi zombutho. Xa kuthelekiswa nezinye iiteknoloji zebhayometri ngokubhekiselele kukhuseleko, ziphuculwe.

Ukongeza kwezi mpawu zebhayomethri zingasentla, iteknoloji yokuqaphela iris nayo iyathandwa. Izinga lokuqaphela iris elingelolokwenyani liphantsi njenge-1/1000000. Isebenzisa ikakhulu iimpawu zokuguquguquka kobomi be-iris kunye nomahluko ukuchonga ubuwena.

Okwangoku, isivumelwano kwishishini kukuba ukuqatshelwa kwendlela enye kuneengxaki ekusebenzeni nasekukhuselekeni kokuqatshelwa, kwaye ukuhlanganiswa kweendlela ezininzi yimpumelelo ebalulekileyo ekuqaphelweni kobuso kwanokuqatshelwa kwebhayomethrikhi—kungekuphela nje ngokusebenzisa izinto ezininzi. Indlela yokuphucula ukuchaneka kokuqatshelwa inokuphucula ukulungelelaniswa kwendawo kunye nokhuseleko lwabucala lwetekhnoloji yebhayomethrikhi ukuya kwinqanaba elithile. Xa kuthelekiswa ne-algorithm yendabuko yendlela enye, inokuhlangabezana ngcono nezinga lokuqatshelwa kobuxoki kwinqanaba lezemali (eliphantsi njengenye kwizigidi ezilishumi), elikwayindlela ephambili yophuhliso lokuchongwa kwebhayomethrikhi.

Inkqubo yebhayomethrikhi ye-multimodal

Iinkqubo ze-biometric ze-multimodal zisebenzisa ii-sensors ezininzi okanye ii-biometrics ukoyisa imida yeenkqubo ze-biometric ze-unimodal. Umzekelo, iinkqubo zokuqaphela iris zinokonakaliswa yi-iris ezidala kwaye ukuqondwa kweminwe ye-elektroniki kunokwenziwa mandundu yiminwe egugileyo okanye enqunyulweyo. Ngelixa iinkqubo ze-biometric ze-unimodal zithintelwe bubunyani besazisi sazo, akunakwenzeka ukuba iinkqubo ezininzi ze-unimodal zibe nemida efanayo. Iinkqubo ze-biometric ze-multimodal zinokufumana iiseti zolwazi oluvela kwi-marker efanayo (oko kukuthi, imifanekiso emininzi ye-iris, okanye ii-scan zomnwe omnye) okanye ulwazi oluvela kwi-biometrics ezahlukeneyo (ezifuna ii-scan zeminwe kwaye, ngokusebenzisa ukuqondwa kwelizwi, i-passcode ethethiweyo).

Iinkqubo ze-biometric ze-multimodal zinokudibanisa ezi nkqubo ze-unimodal ngokulandelelana, ngaxeshanye, indibaniselwano yazo, okanye ngochungechunge, ezibhekisa kwiindlela zokudibanisa ezilandelelanayo, ezihambelanayo, ezihambelanayo kunye nezilandelelanayo, ngokulandelelana.

I-CHANCCTVuphuhlise uthotho lweiilensi zebhayomethrikhiukubonwa kobuso, ukubonwa kwesandla kunye nokubonwa kweminwe kunye nokubonwa kwe-iris. Umzekelo, i-CH3659A yilensi ye-4k eguquguqukayo esezantsi eyenzelwe izinzwa ze-1/1.8''. Inayo yonke imizobo yeglasi kunye ne-compact ene-11.95mm TTL kuphela. Ibamba umbono othe tye we-44 degrees. Le lensi ifanelekile ukubonwa kwesandla.
