Ngokuthuthuka okusheshayo kobuchwepheshe, ubuchwepheshe be-biometric buye basetshenziswa ngokuqhubekayo ekuhloleni okuqhubekayo. Ubuchwepheshe bokuhlonza i-biometric ikakhulukazi bubhekisela kubuchwepheshe obusebenzisa i-biometrics yomuntu ukuze kuqinisekiswe ubuwena. Ngokusekelwe ekwehlukeni kwezici zomuntu ezingenakuphindwa, ubuchwepheshe bokuhlonza i-biometric busetshenziselwa ukuqinisekiswa kobuwena, okuphephile, okuthembekile, nokunembile.
Izici zebhayoloji zomzimba womuntu ezingasetshenziselwa ukuqashelwa kwebhayomethrikhi zihlanganisa ukuma kwesandla, izigxivizo zeminwe, ukuma kobuso, iris, i-retina, ishayela, i-auricle, njll., kuyilapho izici zokuziphatha zifaka isiginesha, izwi, amandla enkinobho, njll. Ngokusekelwe kulokhu izici, abantu bathuthukise ubuchwepheshe obuhlukahlukene bebhayomethrikhi njengokubonwa kwesandla, ukubonwa kwezigxivizo zeminwe, ukubona ubuso, ukuqaphela ukuphimisela, ukuqashelwa kwe-iris, ukuqashelwa kwesiginesha, njll.
Ubuchwepheshe bokuqaphela i-Palmprint (ikakhulukazi ubuchwepheshe bokubona imithambo yesundu) buwubuchwepheshe bokunemba okuphezulu kokubona umazisi bukhoma, futhi bungobunye bobuchwepheshe obuqashelwa kakhulu nobuvikelekile bokuqaphela i-biometric njengamanje. Ingasetshenziswa emabhange, ezindaweni ezilawulayo, ezakhiweni zamahhovisi ezisezingeni eliphezulu nakwezinye izindawo ezidinga ukuhlonzwa okunembayo kobunikazi babasebenzi. Isetshenziswe kakhulu emikhakheni efana nezezimali, ukwelashwa, izindaba zikahulumeni, ukuvikeleka komphakathi kanye nobulungiswa.
Ubuchwepheshe bokubona i-Palmprint
Ubuchwepheshe be-Palmar vein recognition ubuchwepheshe be-biometric obusebenzisa okuhlukile kwemithambo yegazi yesundu ukukhomba abantu ngabanye. Umgomo wayo oyinhloko ukusebenzisa izici zokumuncwa kwe-deoxyhemoglobin emithanjeni kuya ku-760nm ukukhanya okuseduze kwe-infrared ukuthola ulwazi lomkhumbi we-venous.
Ukuze usebenzise ukubonwa komthambo wesundu, qala ngokubeka intende yesandla kwinzwa yesiboni, bese usebenzisa ukuskena kokukhanya okuseduze kwe-infrared ukuze kubonwe ukuze uthole ulwazi lomkhumbi womuntu, bese uqhathanisa futhi uqinisekise ngama-algorithms, amamodeli esizindalwazi, njll. ukuze ekugcineni uthole imiphumela yokuqashelwa.
Uma kuqhathaniswa nobunye ubuchwepheshe bebhayomethrikhi, ukuqashelwa kwemithambo yesundu kunezinzuzo eziyingqayizivele zobuchwepheshe: izici zebhayoloji eziyingqayizivele nezizinzile ngokuqhathaniswa; Isivinini sokuqashelwa okusheshayo nokuvikeleka okuphezulu; Ukwamukela ukuhlonza okungekona othintana naye kungagwema izingozi zezempilo ezibangelwa ukuxhumana okuqondile; Inezinhlobonhlobo zezimo zohlelo lokusebenza kanye nenani eliphezulu lemakethe.
I-Chuang'Ilensi eseduze ne-infrared
Ilensi (imodeli) CH2404AC ithuthukiswe ngokuzimele yi-Chuang'An Optoelectronics iyilensi eseduze ne-infrared eyenzelwe ngqo ukuskena izinhlelo zokusebenza, kanye ne-M6.5 lens enezici ezifana nokuhlanekezela okuphansi nokucaca okuphezulu.
Njengelensi yokuskena eseduze ne-infrared esivuthiwe, i-CH2404AC inesisekelo samakhasimende esizinzile futhi okwamanje isetshenziswa kabanzi emikhiqizweni yetheminali yokuphrinta isundu kanye nemithambo yesundu. Inezinzuzo zohlelo lokusebenza ezinhlelweni zamabhange, izinhlelo zokuphepha zepaki, izinhlelo zokuhamba zomphakathi, neminye imikhakha.
Ukunikezwa kwasendaweni kokubonwa kwe-palm vein CH2404AC
I-Chuang'An Optoelectronics yasungulwa ngo-2010 futhi yaqala ukusungula iyunithi yebhizinisi lokuskena ngo-2013, igxile ekuthuthukisweni kochungechunge lwemikhiqizo yokuskena yamalensi. Sekuyiminyaka eyishumi kusukela lapho.
Namuhla, amalensi okuskena angaphezu kwekhulu avela ku-Chuang'An Optoelectronics anezinhlelo zokusebenza ezivuthiwe emikhakheni efana nokubonwa kobuso, ukubonwa kwe-iris, ukuqashelwa kokuphrinta kwesundu, nokuqashelwa kwezigxivizo zeminwe. Ilensi efana ne-CH166AC, CH177BC, njll., isetshenziswe emkhakheni wokubonwa kwe-iris; I-CH3659C, CH3544CD kanye namanye amalensi asetshenziswa emikhiqizweni yokuqaphela izigxivizo zeminwe.
I-Chuang'An Optoelectronics izibophezele embonini ye-optical lens, igxile ocwaningweni nasekuthuthukisweni nasekukhiqizeni ama-lens optical anencazelo ephezulu kanye nezinsiza ezihlobene, ukuhlinzeka ngezinsizakalo zezithombe ezenziwe ngokwezifiso kanye nezixazululo zezimboni ezihlukahlukene.
Eminyakeni yamuva nje, amalensi okubona athuthukiswe ngokuzimela futhi aklanywa nguChuang'An asetshenziswe kabanzi emikhakheni eyahlukene efana nokuhlolwa kwezimboni, ukuqapha ezokuphepha, ukubona komshini, izimoto zasemoyeni ezinganamuntu, i-DV enyakazayo, imaging eshisayo, i-aerospace, njll., futhi uthole ukutuswa okusabalele kumakhasimende asekhaya nawakwamanye amazwe.
