Biometrics waa cabbirada jidhka iyo xisaabaadka la xidhiidha sifooyinka aadanaha.Xaqiijinta biometric (ama xaqiijinta dhabta ah) waxaa loo isticmaalaa sayniska kombiyuutarka qaab aqoonsi iyo xakameyn gelitaanka.Waxa kale oo loo adeegsadaa in lagu aqoonsado shakhsiyaadka ku jira kooxaha la ilaalinayo.

Aqoonsayaasha biometric waa kuwa kala soocan, sifooyinka la cabbiri karo ee loo isticmaalo in lagu calaamadiyo laguna qeexo shakhsiyaadka.Aqoonsayaasha biometric ayaa inta badan loo kala saaraa sifooyin nafsiyeed kuwaas oo la xidhiidha qaabka jidhka.Tusaalooyinka waxaa ka mid ah, laakiin aan ku xaddidnayn faraha, xididdada timirta, aqoonsiga wejiga, DNA, daabacaadda timirta, joomatari gacanta, aqoonsiga iris, retina, iyo ur/ur.

Tignoolajiyada aqoonsiga Biometric waxay ku lug leedahay sayniska kombiyuutarka, optics iyo acoustics iyo cilmiga kale ee jirka, cilmiga noolaha, biosensors iyo mabaadi'da biostatistics, tignoolajiyada amniga, tignoolajiyada sirdoonka macmal iyo cilmiyo kale oo badan oo aasaasi ah iyo teknooloji codsi cusub.Waa xal farsamo oo dhamaystiran oo kala duwan.

Sanadihii la soo dhaafay, iyada oo la horumarinayo garaadka macmalka ah, tignoolajiyada aqoonsiga biometric ayaa noqotay mid aad u qaangaar ah.Waqtigan xaadirka ah, tignoolajiyada aqoonsiga waji ayaa ah wakiilka ugu badan ee biometrics.

Aqoonsiga wajiga

Habka aqoonsiga wejiga waxaa ka mid ah ururinta wejiga, ogaanshaha wejiga, soo saarista muuqaalka wejiga iyo aqoonsiga u dhigma wejiga.Habka aqoonsiga wejigu wuxuu adeegsadaa tignoolajiyada kala duwan sida AdaBoos algorithm, isku-xidhka neerfaha ee is-daba-joogta ah iyo taageeridda mashiinka vector ee barashada mashiinka.

Habka aqoonsiga wajiga

Waqtigan xaadirka ah, dhibaatooyinka aqoonsiga weji ee soo jireenka ah oo ay ka mid yihiin wareegga wejiga, daboolka, isku ekaanshaha, iwm ayaa si weyn loo hagaajiyay, taas oo si weyn u wanaajisay saxnimada aqoonsiga wejiga.Wejiga 2D, wejiga 3D, wejiga kala duwan ee qaab kastaa wuxuu leeyahay xaalado la qabsiga la qabsiga oo kala duwan, shahaadada amniga xogta iyo xasaasiga gaarka ah, iwm. Waxay si dhakhso ah u aqoonsan kartaa aqoonsiga qofka, taas oo keentay horumar gaar ah oo loogu talagalay codsiga aqoonsiga wejiga laba-geesoodka ah.

Isla mar ahaantaana, tignoolajiyada ogaanshaha biometric ayaa hadda loo isticmaalaa sidii tignoolajiyada muhiimka ah si loo hagaajiyo amniga aqoonsiga wejiga, taas oo si wax ku ool ah u diidi karta khiyaanada been abuurka ah sida sawirada, fiidiyowyada, moodooyinka 3D, iyo maaskaro-prosthetic, oo si madaxbanaan u go'aamiya aqoonsiga isticmaalayaasha hawlgalka.Waqtigan xaadirka ah, horumarka degdega ah ee tignoolajiyada aqoonsiga wejiga, codsiyo badan oo cusub sida aaladaha smart, maaliyadda internetka, iyo lacag bixinta wejiga ayaa noqday mid caan ah oo sii kordheysa, taas oo keenaysa xawaare iyo raaxo qof walba noloshiisa iyo shaqadiisa.

Aqoonsiga calaacalaha

Aqoonsiga calaacalaha waa nooc cusub oo tignoolajiyada aqoonsiga biometric, kaas oo u adeegsada calaacalaha jidhka bini'aadamka sifo bartilmaameedka ah, oo u ururisa macluumaadka noolaha iyada oo loo marayo tignoolajiyada sawir-qaadista badan.Aqoonsiga calaacalaha badan ee spectral waxa loo tixgalin karaa in uu yahay nooc ka mid ah tignoolajiyada aqoonsiga biometric kaas oo isku daraya qaabab badan iyo astaamo badan oo bartilmaameed ah.Tignoolajiyadan cusubi waxay isku daraysaa saddexda astaamood ee lagu aqoonsan karo maqaarka maqaarka, daabacaadda timirta iyo xididdada xididdada si ay u bixiso macluumaad aad u tiro badan hal mar iyo kordhinta kala saarista astaamaha bartilmaameedka.

Sannadkan, tignoolajiyada aqoonsiga timirta ee Amazon, code-ka loo yaqaan Orville, ayaa bilaabay tijaabinta.Sawir-qaaduhu wuxuu marka hore helayaa sawirro asal ah oo infrared polarized ah, oo diiradda saaraya sifooyinka dibadda ee calaacalaha, sida xariiqyada iyo laalaabyada;Marka la helo qaybta labaad ee sawirada polarized mar labaad, waxay diiradda saartaa qaabka calaacalaha iyo sifooyinka gudaha, sida xididada, lafaha, unugyada jilicsan, iwm. Sawirada cayriin ayaa marka hore la farsameeyaa si loo bixiyo sawiro ka kooban gacmo.Sawiradani waa kuwo si fiican u iftiimaya, diirada saaraya, waxayna muujinayaan calaacalaha jihayn gaar ah, meel gaar ah, oo lagu calaamadeeyay inay tahay bidix ama midig.

Waqtigan xaadirka ah, tignoolajiyada aqoonsiga calaacalaha ee Amazon waxay xaqiijin kartaa aqoonsiga shakhsi ahaaneed waxayna ku dhamayn kartaa lacag bixinta 300 millise seconds oo keliya, uma baahna isticmaalayaashu inay gacmahooda saaraan qalabka wax lagu baadho, kaliya luxul iyo iskaan la'aan.Heerka fashilka tignoolajiyadani waa qiyaastii 0.0001%.Isla mar ahaantaana, aqoonsiga calaacalaha ayaa ah xaqiijin labanlaab ah marxaladda hore - marka ugu horeysa ee la helo sifooyinka dibadda, iyo marka labaad si loo helo sifooyin urureed gudaha ah.Marka la barbar dhigo tignoolajiyada kale ee biometric ee dhinaca amniga, waa la hagaajiyay.

Marka lagu daro sifooyinka biometric-ka ee kore, tignoolajiyada aqoonsiga iris ayaa sidoo kale la faafiyay.Heerka aqoonsiga beenta ah ee aqoonsiga iris waa mid hooseeya sida 1/100000.Waxay inta badan adeegsataa sifooyinka nolosha iris-ka ee is-bedbeddelka iyo kala duwanaanshaha si loo aqoonsado aqoonsiga.

Waqtigan xaadirka ah, is-afgaradka warshadaha ayaa ah in aqoonsiga hal qaab-dhismeed uu leeyahay caqabado labadaba waxqabadka aqoonsiga iyo amniga, iyo isku-dhafka qaababka badan ayaa ah horumar muhiim ah oo lagu ogaanayo aqoonsiga wejiga iyo xitaa aqoonsiga biometric-ma aha oo kaliya iyada oo loo marayo arrimo badan. Si loo wanaajiyo saxnaanta aqoonsiga waxay sidoo kale wanaajin kartaa la qabsiga goobta iyo amniga gaarka ah ee tignoolajiyada biometric ilaa xad.Marka la barbar dhigo algorithm-ka caadiga ah ee hal-hab, waxay si fiican u buuxin kartaa heerka aqoonsiga beenta ah ee heerka maaliyadeed (sida ugu hooseeya hal tobankii milyanba), taas oo sidoo kale ah isbeddelka ugu weyn ee horumarinta aqoonsiga biometric.

Hababka kala duwan ee biometric

Nidaamyada biometric-ka ee Multimodal waxay isticmaalaan dareemeyaal badan ama biometrics si ay uga gudbaan xaddidaadda nidaamyada unugyada biometric ee unimodal.Tusaale ahaan nidaamyada aqoonsiga iris waxaa wax u dhimi kara irises gabowga iyo aqoonsiga faraha elektarooniga ah waxaa ka sii dari kara faraha gaboobay ama la jaray.Halka nidaamyada unugyada noole ee midaysan ay xaddidan yihiin daacadnimada aqoonsigooda, uma badna in dhowr nidaam oo midaysan ay la kulmaan xaddidaadyo isku mid ah.Nidaamyada biometric-ga ee Multimodal-ka waxay ka heli karaan xog ururin isku mid ah (tusaale, sawirro badan oo iris ah, ama sawiro isla far isku mid ah) ama macluumaadka biometrics kala duwan (u baahan sawir-qaadista faraha iyo, adeegsiga aqoonsiga codka, lambarka sirta ah ee lagu hadlo).

Nidaamyada hab-nololeedka ee Multimodal-ka waxay isku darsanaan karaan nidaamyadan midaysan si isku xigta, isku mar, isku-dar ah, ama taxane ah, kuwaas oo tixraacaya qaababka isku-xiran, isbar-bar-dhigga, kala sareynta iyo is-dhexgalka taxanaha ah, siday u kala horreeyaan.

CHANCCTVwuxuu sameeyay taxane ahmuraayadaha biometricAqoonsiga wejiga, aqoonsiga calaacalaha iyo sidoo kale aqoonsiga faraha iyo aqoonsiga iris.Tusaale ahaan CH3659A waa muraayad qalloocan oo hooseeya oo 4k ah kaas oo loogu talagalay 1/1.8'' dareemayaasha.Waxay ka kooban tahay dhammaan muraayadaha iyo naqshadaha is haysta oo leh kaliya 11.95mm TTL.Waxay qabtaa 44 digrii goob muuqaal toosan.Muraayaddani waxay ku habboon tahay aqoonsiga timirta.
