Ndi chitukuko chofulumira chaukadaulo, ukadaulo wa biometric wagwiritsidwa ntchito kwambiri pakufufuza kosalekeza. Ukadaulo wozindikiritsa ma biometric makamaka umatanthawuza ukadaulo womwe umagwiritsa ntchito ma biometric amunthu potsimikizira kuti ndi ndani. Kutengera ndi mawonekedwe apadera a anthu omwe sangathe kubwerezedwanso, umisiri wozindikiritsa ma biometric amagwiritsidwa ntchito potsimikizira kuti ndi ndani, zomwe ndi zotetezeka, zodalirika komanso zolondola.
Zachilengedwe za thupi la munthu zomwe zitha kugwiritsidwa ntchito kuzindikira za biometric zimaphatikiza mawonekedwe a dzanja, zala, mawonekedwe a nkhope, iris, retina, kugunda, auricle, ndi zina zambiri, pomwe mawonekedwe amaphatikizira siginecha, mawu, mphamvu ya batani, ndi zina zambiri. Kutengera izi zinthu, anthu apanga umisiri zosiyanasiyana biometric monga kuzindikira dzanja, kuzindikira zala, kuzindikira nkhope, kuzindikira katchulidwe, kuzindikira iris, kuzindikira siginecha, etc.
Ukadaulo wozindikira za Palmprint (makamaka ukadaulo wozindikiritsa mitsempha ya kanjedza) ndiukadaulo wapamwamba kwambiri wozindikiritsa zidziwitso, komanso ndi imodzi mwaukadaulo wodziwika bwino komanso wotetezeka wozindikiritsa ma biometric pakali pano. Itha kugwiritsidwa ntchito m'mabanki, malo owongolera, nyumba zamaofesi apamwamba ndi malo ena omwe amafunikira kuzindikirika bwino kwa anthu ogwira ntchito. Zakhala zikugwiritsidwa ntchito kwambiri m'madera monga zachuma, chithandizo chamankhwala, zochitika za boma, chitetezo cha anthu ndi chilungamo.
Tekinoloje yozindikiritsa Palmprint
Ukadaulo wozindikira mtsempha wa Palmar ndi ukadaulo wa biometric womwe umagwiritsa ntchito mitsempha yamagazi ya kanjedza kuzindikira anthu. Mfundo yake yayikulu ndikugwiritsa ntchito mawonekedwe a mayamwidwe a deoxyhemoglobin m'mitsempha kupita ku 760nm pafupi ndi kuwala kwa infrared kuti mupeze chidziwitso cha venous chotengera.
Kuti mugwiritse ntchito kuzindikira kwa mtsempha wa palmar, choyamba ikani chikhato chanu pa sensa ya chozindikira, kenako gwiritsani ntchito kuwunika kwapafupi ndi infrared kuti muzindikire kuti mupeze zidziwitso za chotengera chamunthu, kenako ndikufananiza ndikutsimikizira kudzera mu ma aligorivimu, mitundu ya database, ndi zina zambiri kuti pamapeto pake mupeze zotsatira zozindikirika.
Poyerekeza ndi matekinoloje ena a biometric, kuzindikira kwa mitsempha ya kanjedza kuli ndi ubwino wapadera waukadaulo: mawonekedwe apadera komanso okhazikika achilengedwe; Kuthamanga kwachangu kuzindikira ndi chitetezo chachikulu; Kutenga zizindikiritso zosagwirizana ndi anthu kungapewe ngozi zomwe zimachitika chifukwa cholumikizana mwachindunji; Ili ndi zochitika zosiyanasiyana zogwiritsira ntchito komanso mtengo wamsika wamsika.
Chuang'An pafupi-infrared lens
Magalasi (chitsanzo) CH2404AC opangidwa paokha ndi Chuang'An Optoelectronics ndi lens yapafupi ndi infrared yopangidwa makamaka kuti ifufuze ntchito, komanso lens ya M6.5 yokhala ndi makhalidwe monga kusokoneza pang'ono ndi kusintha kwakukulu.
Monga ma lens okhwima omwe ali pafupi ndi infrared, CH2404AC ili ndi makasitomala okhazikika ndipo pakadali pano imagwiritsidwa ntchito kwambiri pazosindikiza za kanjedza ndi zida zozindikiritsa mitsempha ya kanjedza. Ili ndi maubwino ogwiritsira ntchito m'mabanki, machitidwe otetezera mapaki, machitidwe oyendera anthu onse, ndi magawo ena.
Kupereka kwanuko kwa kuzindikira kwa mtsempha wa kanjedza wa CH2404AC
Chuang'An Optoelectronics idakhazikitsidwa mchaka cha 2010 ndipo idayamba kukhazikitsa bizinesi yojambulira mu 2013, ikuyang'ana kwambiri pakupanga zinthu zingapo zamagalasi. Patha zaka khumi kuchokera pamenepo.
Masiku ano, magalasi ojambulira zana kuchokera ku Chuang'An Optoelectronics ali ndi ntchito zokhwima m'magawo monga kuzindikira nkhope, kuzindikira kwa iris, kuzindikira zolemba za kanjedza, komanso kuzindikira zala. Magalasi monga CH166AC, CH177BC, etc., amagwiritsidwa ntchito pozindikira iris; CH3659C, CH3544CD ndi magalasi ena amagwiritsidwa ntchito pazosindikiza za kanjedza ndi zinthu zozindikiritsa zala.
Chuang'An Optoelectronics akudzipereka ku makampani opanga magalasi, akuyang'ana pa kafukufuku ndi chitukuko ndi kupanga magalasi apamwamba kwambiri opangira magalasi ndi zina zowonjezera, kupereka ntchito zowonetsera zithunzi ndi njira zothetsera mafakitale osiyanasiyana.
M'zaka zaposachedwa, magalasi owoneka bwino opangidwa ndi Chuang'An akhala akugwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga kuyesa kwa mafakitale, kuyang'anira chitetezo, masomphenya a makina, magalimoto osayendetsedwa ndi ndege, kuyenda kwa DV, kujambula kwamafuta, mlengalenga, ndi zina zambiri. adalandira kutamandidwa kofala kuchokera kwa makasitomala apakhomo ndi akunja.
