Adam Kos Haasi ese mafoni anoshandisa tekinoroji yekuvhura kumeso. Vamwe vakachengeteka, vamwe zvishoma. Vamwe vanoongorora mu3D, vamwe mu2D. Nekudaro, kunyangwe nekukosha kuri kukura kwechengetedzo, iwe unofanirwa kuziva kuti hazvisi zvese zvekuzivikanwa kwechiso kuita zvinogadzirwa zvakaenzana.
Kuzivikanwa kwechiso uchishandisa kamera
Sezvinoratidzwa nezita racho, nzira iyi inotsamira pamakamera akatarisana nemudziyo wako kuti aone chiso chako. Anenge ese ma smartphones eAroid akabatanidza chinhu ichi kubva pakaburitswa Android 4.0 Ice Cream Sandwich muna 2011, yaive nguva refu Apple isati yauya neFace ID yayo. Mashandiro ayo ari nyore. Paunomisikidza chimiro kekutanga, chishandiso chako chinokukurudzira kuti utore mifananidzo yechiso chako, dzimwe nguva kubva kumakona akasiyana. Inobva yashandisa algorithm yesoftware kubvisa zviso zvako uye kuzvichengeta kuti zvizoshandiswa mune ramangwana. Kubva zvino zvichienda mberi, pese paunoyedza kuvhura chishandiso, iyo mhenyu mufananidzo kubva kumberi kamera inofananidzwa nereferenzi data.
Kurongeka kunoenderana zvakanyanya nesoftware algorithms inoshandiswa, saka sisitimu iri kure nekukwana. Zvinotonyanya kuoma kana mudziyo uchifunga nezvezvakasiyana zvakaita semamiriro emwenje akasiyana, shanduko mukutaridzika kwemushandisi uye mashandisirwo emidziyo yakadai semagirazi uye zvishongo zvakanyanya. Nepo Android pachayo ichipa API yekuzivikanwa kumeso, vagadziri ve smartphone vakagadzirawo yavo mhinduro mumakore apfuura. Pakazara, chinangwa chaive chekuvandudza kukurumidza kucherechedzwa pasina kupira kurongeka zvakanyanya.
Zvinogona kudaro kufarira iwe
Vratislav Holub Kuzivikanwa kwechiso kunobva pane infrared radiation
Infrared face recognition inoda imwe hardware kune yekumberi kamera. Nekudaro, hadzisi dzese infrared face recognition mhinduro dzakagadzirwa zvakaenzana. Rudzi rwekutanga runosanganisira kutora mufananidzo une mativi maviri echiso chako, wakafanana nenzira yapfuura, asi mune infrared spectrum pachinzvimbo. Chakanyanya kukosha ndechekuti infrared makamera haadi kuti chiso chako chivheneke zvakanaka uye anogona kushanda munzvimbo dzine dimlight. Ivo zvakare vanoramba zvakanyanya kutyora-mukati kuyedza nekuti infrared makamera anoshandisa kupisa simba kugadzira mufananidzo.
Face ID
Nepo 2D infrared face recognition yatove kusvetuka uye kusungirirwa pamberi penzira dzechinyakare dzakavakirwa pamifananidzo yekamera, pane imwe nzira iri nani. Izvo, hongu, iApple's Face ID, iyo inoshandisa akatevedzana ma sensors kutora matatu-dimensional inomiririra yechiso chako. Iyi nzira inoshandisa kamera yekumberi chete zvishoma, sezvo yakawanda yedata inowanikwa nemamwe ma sensors anotarisa kumeso kwako. Chivheneko, infrared dot projector uye infrared kamera zvinoshandiswa pano.
Iyo yekuvhenekesa inotanga kuvhenekera chiso chako nechiedza che infrared, iyo dot projekta inogadzira 30 infrared dots pairi, iyo inotorwa nekamera infrared. Iyo yekupedzisira inogadzira yakadzama mepu yechiso chako uye nekudaro inowana chaiyo yechiso data. Zvese zvinobva zvaongororwa neural injini, iyo inofananidza mepu yakadaro nedata rakatorwa kana basa raitwa.
Face unlock yakanakira, asi inogona kunge isina kuchengetedzwa
Hapana kupokana kuti 3D kuzivikanwa kwechiso uchishandisa infrared mwenje ndiyo nzira yakachengeteka zvakanyanya. Uye Apple inoziva izvi, ndosaka, kunyangwe kusafara kwevashandisi vazhinji, inochengeta kuchekwa muchiratidziro paPhones dzayo kudzamara yaona kupi uye sei kuvanza ma sensors ega. Uye sezvo kucheka kusingapfekwe munyika yeAroid, tekinoroji yekutanga inotsamira pamifananidzo chete ndiyo yakajairika pano, kunyangwe ichiwedzerwa neakawanda smart algorithms. Kunyange zvakadaro, vagadziri vazhinji vezvishandiso zvakadaro havakubvumiri kuti uzvishandise kune zvakanyanya kuoma maapplication. Ndokusaka munyika ye Android, semuenzaniso, tekinoroji yeiyo under-display ultrasonic fingerprint reader ine huremu hwakawanda.
Pfungwa iPhone ine Bata ID pasi pechiratidziro
Nekudaro, muiyo Android sisitimu, iyo Google nharembozha masevhisi certification chirongwa chinoisa mashoma ekuchengetedza miganhu yeakasiyana biometric echokwadi nzira. Nzira dzisina kuchengetedzeka dzekuvhura, dzakadai sekuvhurwa kwechiso nekamera, dzinobva dzaiswa se "zvakanakira". Zvichitaurwa zviri nyore, haagone kushandiswa kuonesa muzvishandiso zvine hunyanzvi seGoogle Pay uye mazita ekubhengi. Apple's Face ID inogona kushandiswa kukiya nekuvhura chero chinhu, pamwe nekubhadhara nayo, nezvimwe.
Mune mafoni, biometric data inowanzo kuvharidzirwa uye yakaparadzaniswa mune yakachengetedzwa-yakachengetedzwa Hardware mukati memudziyo wako-on-chip (SoC). Qualcomm, imwe yevagadziri vakuru vemachipisi emafoni ane Android system, inosanganisira Yakachengeteka Kugadziridza Unit muSoCs yayo, Samsung ine Knox Vault, uye Apple, kune rumwe rutivi, ine Yakachengeteka Enclave subsystem.

Kare neremangwana
Kushandiswa kwakavakirwa pachiedza che infrared kwave kushoma mumakore mashoma apfuura, kunyangwe iwo ari akachengeteka zvakanyanya. Kunze kwePhones uye iPad Pros, akawanda ma-smartphones haachave nemasensa anodiwa. Iye zvino mamiriro acho ari nyore, uye zvinonzwika senge Apple mhinduro. Nekudaro, pakanga paine nguva apo akawanda madivaysi eAroid, kubva pakati-renji kusvika kumureza, aive nemidziyo inodiwa. Semuenzaniso, iyo Samsung Galaxy S8 neS9 yakakwanisa kuziva iris yeziso, Google yakapa kuvhurwa kwechiso kunonzi Soli muPixel 4 yayo, uye 3D yekuvhura kumeso kwaiwanikwawo paHuawei Mate 20 Pro foni. Asi haudi cutout? Iwe hauzove neIR sensors.
Nekudaro, kunyangwe kubviswa kwavo kubva kuAndroid ecosystem, zvinogoneka kuti kucherechedzwa kwemhando yepamusoro kwechiso kuchadzoka pane imwe nguva. Iko kune kwete chete mafingerprint sensors asiwo makamera pasi pechiratidziro. Saka ingangove ingori nyaya yenguva isati infrared sensors iwane kurapwa kumwe chete. Uye panguva iyoyo tichaonekana kune cutouts zvakanaka, pamwe kunyange kuApple.
Zvakanaka, ndingataura kuti android haifanirwe kubata neizvi, nekuti haina kubvisa zvigunwe zvemunwe sensors uye kazhinji haimanikidze chero munhu kushandisa nzira yakadaro.
