Batyhila ubuchule bokubona iikhamera ezifihliweyo zisebenzisa i-sensor ye-ToF yee-smartphones

Abaphandi abavela kwiYunivesithi yeSizwe yaseSingapore kunye neYunivesithi yase Yonseo (Korea) baye bavelisa indlela yokubona iikhamera ezifihlakeleyo kwigumbi usebenzisa i-smartphone eqhelekileyo exhotyiswe ngenzwa ye-ToF.

Olu phando luvela kwinkxalabo yangoku yokuba namhlanje ikhamera efihliweyo ingathengwa ngaphezu kwedola kwaye ezi ntlobo zeekhamera zine-lens enobubanzi be-1-2 millimeters, okwenza kube nzima ukuzifumana ngaphakathi. EMzantsi Korea, zingaphezu kwama-6.800 XNUMX iziganeko ezibandakanya ukubekwa kweekhamera ezifihlakeleyo kumagumbi ehotele okanye kumagumbi okuhlambela zarekhodwa ngonyaka.

Indlela I-LAPD (Ukufunyanwa kweFoto yokuNcedisa ngeLaser) ecetywe ngabaphandi ivumela ukubona iikhamera ezifihliweyo usebenzisa ii-smartphones zanamhlanje ezinezixhobo isivamvo sobunzulu (TOF), esetyenziselwa ukuqikelela umgama kwizinto xa kugxilwe kwikhamera nakwizicelo zenyani ezandisiweyo.

Phakathi kwezixhobo ezisetyenzisiweyo, i-Samsung S20 kunye neHuawei P30 Pro zikhankanywa njengemizekelo yee-smartphones ezisebenzisa ezi zivamvo. I-sensor yenza imephu enzulu ngokuskena indawo ejikelezileyo ngelaser kwaye ibale umgama ngokusekelwe ekufikeni kokulibaziseka komqadi obonakalisiweyo.

Iikhamera ezincinci zentlola ezifihlwe kwiindawo ezinovakalelo njenge iihotele kunye nezindlu zangasese eziye zaba sisisongelo esikhulu kwihlabathi jikelele. Ezi khamera zifihliweyo zinokuthengwa ngokulula kwaye kunzima kakhulu ukuzifumana ngeliso lenyama ngenxa yefomu yabo encinci. 
Izisombululo zaseburhulumenteni ezijolise ekuboneni ezi khamera zilinganiselwe njengoko zifuna izixhobo ezikhethekileyo kwaye zivelise ukubonwa okuphantsi.

Indlela yokukhangela iikhamera ezifihliweyo ixhomekeke ekuboneni izinto ezingaqhelekanga xa iilensi kunye neelensi zikhanyiswa ngelaser, zenza amadangatye athile. kwimephu yobunzulu besiphumo. Iimpazamo zichongwa nge-algorithm yokufunda oluzenzekelayo olunokwahlula ilitha elithile lekhamera. Ababhali bokufunda banenjongo yokupapasha isicelo esigqityiweyo seqonga le-Android emva kokulungisa imiba ethile ngezithintelo ze-API.

Amaphepha emfundo yamva nje acebisa ukuhlalutya i-traffic engenazingcingo yenziwe ziikhamera ezifihliweyo. Ezi zindululo, nangona kunjalo, nazo umda ngenxa yokuba bacinga ukuhanjiswa kwevidiyo ngaphandle kwamacingo, ngelixa kuphela
inokubona ubukho beekhamera ezifihliweyo, kwaye akunjalo iindawo zabo.

Ukoyisa le mida, sibonisa i-LAPD, a Ukufunyanwa kwekhamera efihliweyo entsha kunye nenkqubo yendawo ethatha ithuba lexesha lokubhabha (ToF) sensor kwii-smartphones ezisisiseko.

Ixesha elipheleleyo elithathayo ukuskena igumbi liqikelelwa ukuba yi-30-60 imizuzwana. Kuvavanyo olwenziwa ngamavolontiya angama-379, iikhamera ezifihliweyo zafunyanwa ngendlela ye-LAPD kwi-88,9% yamatyala.

Ukuthelekisa, kuphela i-46% yabathathi-nxaxheba ekuvavanyeni bakwazi ukufumana iikhamera ngeso kunye nokusebenza kakuhle kokusebenzisa i-specitor ye-K18 ekhethekileyo yayiyi-62,3% kunye ne-57,7%, kuxhomekeke kwindlela yokuskena ekhethiweyo. Indlela ye-LAPD nayo ibonise izinga elisezantsi lobuxoki: i-16.67% xa ithelekiswa ne-26.9% / 35.2% ye-K18 kunye ne-54.9% xa kukhangelwa ngeso.

Sisebenzisa i-LAPD njengesicelo se-smartphone esikhupha imiqondiso ye-laser ukusuka kwinzwa ye-ToF usebenzisa umbono wekhompyuter kunye nokufunda koomatshini ukufumana imiboniso eyodwa yeekhamera ezifihliweyo.

Sivavanya i-LAPD ngokusebenzisa imifuniselo ebanzi yehlabathi lokwenyani ukugaya abathathi-nxaxheba abangama-379 kwaye bajonge ukuba i-LAPD ifezekisa tI-88,9% efihliweyo yokukhangela ikhamera yokukhangela, ngelixa isetyenziswe kuphela ngeso lenyama ivelisa kuphela i-46,0% efihliweyo izinga lokubona ikhamera.

Ukuchaneka kokufumanisa kwe-LAPD kuxhomekeke kwikhamera efihliweyo efikelela kwi-angle ye-20 yokujonga i-sensor kwaye ikumgama ofanelekileyo ukusuka kwinzwa (isondele kakhulu, i-lens flare yekhamera imnyama, kwaye ukuba ikude kakhulu, iyanyamalala).

Ukuphucula ukuchaneka, kucetywayo ukusebenzisa abenzi boluvo abanesisombululo esiphezulu (kwii-smartphones ezifumanekayo kubaphandi, isisombululo senzwa ye-ToF yi-320 × 240, oko kukuthi, ubungakanani be-anomaly emfanekisweni yi-pixels eyi-1-2 kuphela) kunye neenkcukacha ezinzulu (ngoku kukho amanqanaba asi-8 kuphela kwi-pixel nganye).

Ezinye iindlela zokuvavanya ubukho bekhamera efihliweyo ziquka abahlalutyi bezithuthi ezingenazingcingo ezibona ubukho bokuhanjiswa kwevidiyo kwinethiwekhi engenazingcingo, kunye neeskena zemitha ye-electromagnetic.

Okokugqibela, ukuba unomdla wokwazi okungakumbi ngayo, unokujonga iinkcukacha Kule khonkco ilandelayo.
