Chifukwa cha kupita patsogolo kwa ukadaulo mwachangu, ukadaulo wa biometric wakhala ukugwiritsidwa ntchito kwambiri pakufufuza kosalekeza. Ukadaulo wozindikiritsa wa biometric makamaka umatanthauza ukadaulo womwe umagwiritsa ntchito biometrics ya anthu potsimikizira kuti ndi ndani. Kutengera mawonekedwe apadera a anthu omwe sangabwerezedwe, ukadaulo wozindikiritsa wa biometric umagwiritsidwa ntchito potsimikizira kuti ndi ndani, womwe ndi wotetezeka, wodalirika, komanso wolondola.
Makhalidwe a thupi la munthu omwe angagwiritsidwe ntchito pozindikira mawonekedwe a manja ndi monga mawonekedwe a dzanja, zala, mawonekedwe a nkhope, iris, retina, kugunda kwa mtima, auricle, ndi zina zotero, pomwe makhalidwe a thupi ndi monga signature, mawu, mphamvu ya batani, ndi zina zotero. Kutengera ndi mawonekedwe awa, anthu apanga ukadaulo wosiyanasiyana wa biometric monga kuzindikira dzanja, kuzindikira zala, kuzindikira nkhope, kuzindikira katchulidwe, kuzindikira iris, kuzindikira zizindikiro, ndi zina zotero.
Ukadaulo wozindikira zizindikiro za kanjedza (makamaka ukadaulo wozindikira mitsempha ya kanjedza) ndi ukadaulo wozindikira zizindikiro zamoyo molondola kwambiri, komanso ndi umodzi mwa ukadaulo wodziwika bwino komanso wotetezeka kwambiri pakali pano. Ungagwiritsidwe ntchito m'mabanki, m'malo olamulira, m'nyumba zapamwamba zamaofesi ndi m'malo ena omwe amafunika kudziwika bwino kwa anthu ogwira ntchito. Wagwiritsidwa ntchito kwambiri m'magawo monga zachuma, chithandizo chamankhwala, nkhani za boma, chitetezo cha anthu ndi chilungamo.
Ukadaulo wozindikira zilembo za kanjedza
Ukadaulo wozindikira mitsempha ya Palmar ndi ukadaulo wa biometric womwe umagwiritsa ntchito kusiyanasiyana kwa mitsempha yamagazi ya kanjedza kuti uzindikire anthu. Mfundo yake yayikulu ndikugwiritsa ntchito mawonekedwe a deoxyhemoglobin m'mitsempha mpaka 760nm pafupi ndi infrared kuwala kuti mupeze zambiri za mitsempha yamagazi.
Kuti mugwiritse ntchito kuzindikira mitsempha ya kanjedza, choyamba ikani chikhatho pa sensa ya chozindikira, kenako gwiritsani ntchito kusanthula kuwala kwapafupi ndi infrared kuti muzindikire kuti mupeze zambiri za mitsempha ya anthu, kenako yerekezerani ndikutsimikizira kudzera mu ma algorithms, mitundu ya database, ndi zina zotero kuti mupeze zotsatira zozindikira.
Poyerekeza ndi ukadaulo wina wa biometric, kuzindikira mitsempha ya kanjedza kuli ndi ubwino wapadera waukadaulo: mawonekedwe apadera komanso okhazikika achilengedwe; Kuthamanga kwa kuzindikira mwachangu komanso chitetezo chambiri; Kugwiritsa ntchito chizindikiritso chosakhudzana ndi munthu kungapewe zoopsa paumoyo zomwe zimachitika chifukwa chokhudzana mwachindunji; Ili ndi mitundu yosiyanasiyana ya ntchito komanso mtengo wake wamsika.
Lenzi ya Chuang'An pafupi ndi infrared
Lenzi (chitsanzo) CH2404AC yopangidwa payokha ndi Chuang'An Optoelectronics ndi lenzi yapafupi ndi infrared yopangidwira makamaka ntchito zojambulira, komanso lenzi ya M6.5 yokhala ndi mawonekedwe monga kupotoza kochepa komanso mawonekedwe apamwamba.
Popeza ndi lenzi yowunikira pafupi ndi infrared, CH2404AC ili ndi makasitomala okhazikika ndipo pakadali pano imagwiritsidwa ntchito kwambiri pazinthu zosindikizira kanjedza ndi zozindikira mitsempha ya kanjedza. Ili ndi ubwino wogwiritsidwa ntchito m'mabanki, machitidwe achitetezo a paki, machitidwe oyendera anthu onse, ndi zina.
Kujambula kwapafupi kwa CH2404AC kuzindikira mitsempha ya kanjedza
Chuang'An Optoelectronics idakhazikitsidwa mu 2010 ndipo idayamba kukhazikitsa bizinesi yowunikira mu 2013, ikuyang'ana kwambiri pakupanga zinthu zingapo zowunikira. Papita zaka khumi kuchokera pamenepo.
Masiku ano, magalasi opitilira zana ojambulira zithunzi ochokera ku Chuang'An Optoelectronics ali ndi ntchito zazikulu m'magawo monga kuzindikira nkhope, kuzindikira iris, kuzindikira zolemba za kanjedza, ndi kuzindikira zala. Magalasi monga CH166AC, CH177BC, ndi zina zotero, amagwiritsidwa ntchito pozindikira iris; CH3659C, CH3544CD ndi magalasi ena amagwiritsidwa ntchito pozindikira zolemba za kanjedza ndi zala.
Chuang'An Optoelectronics yadzipereka ku makampani opanga ma lens optical, kuyang'ana kwambiri pa kafukufuku, chitukuko ndi kupanga ma lens optical apamwamba komanso zowonjezera zina, kupereka ntchito zowonetsera zithunzi ndi mayankho amitundu yosiyanasiyana.
M'zaka zaposachedwa, magalasi opangidwa ndi kupangidwa paokha ndi Chuang'An akhala akugwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga kuyesa mafakitale, kuyang'anira chitetezo, kuwona makina, magalimoto amlengalenga opanda anthu, mayendedwe a DV, kujambula kutentha, ndege, ndi zina zotero, ndipo alandiridwa ndi anthu ambiri kuchokera kwa makasitomala am'deralo ndi akunja.
