Adam Kos Si mafoni onse omwe amagwiritsa ntchito ukadaulo wofanana wotsegula nkhope. Zina ndi zotetezeka, zina zochepa. Ena amajambula mu 3D, ena mu 2D. Komabe, ngakhale kufunikira kokulirapo kwa chitetezo, muyenera kudziwa kuti sizinthu zonse zozindikiritsa nkhope zomwe zimapangidwa mofanana.
Kuzindikira nkhope pogwiritsa ntchito kamera
Monga momwe dzinalo likusonyezera, njirayi imadalira makamera akutsogolo a chipangizo chanu kuti adziwe nkhope yanu. Pafupifupi mafoni onse amtundu wa Android adaphatikiza izi kuyambira pomwe Android 4.0 Ice Cream Sandwich idatulutsidwa mu 2011, zomwe zidali kale Apple asanabwere ndi ID yake ya nkhope. Momwe zimagwirira ntchito ndizosavuta. Mukatsegula gawolo kwa nthawi yoyamba, chipangizo chanu chimakulimbikitsani kujambula zithunzi za nkhope yanu, nthawi zina mosiyanasiyana. Kenako imagwiritsa ntchito algorithm yamapulogalamu kuti ichotse mawonekedwe amaso anu ndikusunga kuti mudzawagwiritse ntchito mtsogolo. Kuyambira pano, nthawi iliyonse mukayesa kutsegula chipangizocho, chithunzi chamoyo kuchokera ku kamera yakutsogolo chikufaniziridwa ndi zomwe zikuwonetsedwa.
Kulondola kumadalira makamaka ma aligorivimu a mapulogalamu omwe amagwiritsidwa ntchito, kotero dongosololi liri kutali kwambiri ndi langwiro. Zimakhala zovuta kwambiri pamene chipangizocho chiyenera kuganizira zosiyana siyana monga mikhalidwe yowunikira, kusintha kwa maonekedwe a wogwiritsa ntchito komanso kugwiritsa ntchito zipangizo monga magalasi ndi zodzikongoletsera makamaka. Ngakhale Android palokha imapereka API yodziwika ndi nkhope, opanga mafoni apanganso mayankho awo pazaka zambiri. Ponseponse, cholinga chake chinali kupititsa patsogolo liwiro la kuzindikira popanda kusiya kulondola kwambiri.

Vratislav Holub Kuzindikira nkhope kutengera ma radiation a infrared
Kuzindikira kumaso kwa infrared kumafunikira zida zowonjezera ku kamera yakutsogolo. Komabe, si njira zonse zozindikiritsa nkhope za infrared zomwe zimapangidwa mofanana. Mtundu woyamba umaphatikizapo kutenga chithunzi cha mbali ziwiri cha nkhope yanu, mofanana ndi njira yapitayi, koma mu mawonekedwe a infrared m'malo mwake. Ubwino waukulu ndikuti makamera a infrared safuna kuti nkhope yanu ikhale yowunikira bwino ndipo imatha kugwira ntchito m'malo osawoneka bwino. Amakhalanso osamva zoyeserera chifukwa makamera a infrared amagwiritsa ntchito kutentha kuti apange chithunzicho.
Foni ya nkhope
Ngakhale kuzindikira kwa nkhope ya 2D infrared kwayamba kale kudumpha ndi kupitilira njira zachikhalidwe potengera zithunzi za kamera, pali njira yabwinoko. Izi, zachidziwikire, ndi ID ya nkhope ya Apple, yomwe imagwiritsa ntchito masensa angapo kuti ijambule mawonekedwe atatu a nkhope yanu. Njirayi imagwiritsa ntchito kamera yakutsogolo pang'ono, chifukwa zambiri zimapezedwa ndi masensa ena omwe amasanthula nkhope yanu. Zounikira, purojekitala ya madontho a infrared ndi kamera ya infrared amagwiritsidwa ntchito pano.
Chowunikira choyamba chimawunikira nkhope yanu ndi kuwala kwa infrared, projekiti yamadontho imapanga madontho 30 a infrared pamenepo, omwe amajambulidwa ndi kamera ya infrared. Chotsatiracho chimapanga mapu akuya a nkhope yanu ndipo motero amapeza deta yolondola ya nkhope. Chilichonse chimawunikidwa ndi injini ya neural, yomwe imafananiza mapu oterowo ndi deta yojambulidwa pamene ntchitoyo yatsegulidwa.
Kutsegula kumaso ndikosavuta, koma sikungakhale kotetezeka
Palibe kutsutsa kuti kuzindikira nkhope ya 3D pogwiritsa ntchito kuwala kwa infrared ndiyo njira yotetezeka kwambiri. Ndipo Apple akudziwa izi, ndichifukwa chake, ngakhale osasangalala ndi ogwiritsa ntchito ambiri, amasunga chodulidwacho pachiwonetsero pa ma iPhones awo mpaka atazindikira komwe angabise komanso momwe angabisire masensawo. Ndipo popeza ma cutouts samavala mdziko la Android, ukadaulo woyamba womwe umadalira pazithunzi umakhala wanthawi zonse pano, ngakhale wophatikizidwa ndi ma algorithms ambiri anzeru. Ngakhale zili choncho, ambiri opanga zida zotere sangalole kuti muzigwiritsa ntchito pazinthu zovuta kwambiri. Ichi ndichifukwa chake m'dziko la Android, mwachitsanzo, ukadaulo wa owerenga zala zomwe zikuwonetsa zala zala zala zimakhala zolemera kwambiri.
Lingalirani iPhone yokhala ndi ID ID pansi pa chiwonetsero
Chifukwa chake, m'dongosolo la Android, pulogalamu yotsimikizira ntchito zam'manja za Google imayika malire ochepera achitetezo panjira zosiyanasiyana zotsimikizira za biometric. Njira zotsegula zosatetezedwa, monga kutsegula nkhope ndi kamera, zimatchedwa "zosavuta". Mwachidule, sangagwiritsidwe ntchito kutsimikizira pazinthu zachinsinsi monga Google Pay ndi maudindo akubanki. Face ID ya Apple itha kugwiritsidwa ntchito kutseka ndikutsegula chilichonse, komanso kulipira nayo, ndi zina.
M'ma foni a m'manja, ma biometric nthawi zambiri amabisidwa ndikukhazikika pazida zotetezedwa mkati mwa chipangizo chanu pa system-on-chip (SoC). Qualcomm, m'modzi mwa opanga zazikulu kwambiri zama tchipisi a mafoni okhala ndi Android system, akuphatikiza Secure Processing Unit mu SoCs zake, Samsung ili ndi Knox Vault, ndipo Apple, kumbali ina, ili ndi Secure Enclave subsystem.

Zakale ndi zamtsogolo
Kugwiritsa ntchito kutengera kuwala kwa infrared kwakhala kosowa kwambiri m'zaka zingapo zapitazi, ngakhale ndi kotetezeka kwambiri. Kupatula ma iPhones ndi iPad Ubwino, mafoni ambiri sakhalanso ndi zomvera zofunika. Tsopano zinthu ndizosavuta, ndipo zikuwoneka bwino ngati yankho la Apple. Komabe, panali nthawi yomwe zida zambiri za Android, kuyambira pakatikati mpaka pazithunzi, zinali ndi zida zofunikira. Mwachitsanzo, Samsung Galaxy S8 ndi S9 adatha kuzindikira iris ya diso, Google idapereka mafungulo amaso otchedwa Soli mu Pixel 4 yake, ndi kutsegula kumaso kwa 3D kunalinso pa foni ya Huawei Mate 20 Pro. Koma simukufuna kudula? Simudzakhala ndi masensa a IR.
Komabe, ngakhale atachotsedwa ku chilengedwe cha Android, ndizotheka kuti kuzindikira kwamawonekedwe apamwamba koteroko kudzabweranso nthawi ina. Palibe zowonera zala zala komanso makamera pansi pa chiwonetsero. Chifukwa chake mwina ndi nthawi yokhayo kuti masensa a infrared alandire chithandizo chimodzimodzi. Ndipo panthawiyo tidzatsazikana ndi cutouts zabwino, mwina ngakhale ku Apple.
Chabwino, ndinganene kuti Android sichiyenera kuthana ndi izi, chifukwa sichinachotse zomvera zala zake ndipo nthawi zambiri sichikakamiza aliyense kugwiritsa ntchito njira yotereyi.
