Indlela ukuzwela kwe-IR okunomthelela ngayo ekwakhiweni kwekhamera yokubona ebusuku
Kwadalwa ngo 10.10
Hamba kunoma yimuphi umbukiso wokuhweba ngezinto zikagesi, futhi uzobona amamojula amakhamera amaningi akhangiswa ngokuthi “10m night vision” noma “0.001 lux low-light performance.” Zimbalwa izicaciso ezisetshenziswa ngokunganaki — nangokungaqondile — njengokuzwela kwe-infrared. Kubadwebi bemikhiqizo kanye namaqembu onjiniyela, nokho, ukuzwela kwe-IR akusona iphuzu lokukhangisa. Kuyisithiyo esiyisisekelo esibumba cishe zonke izinqumo ku-uhlelo lwekhamera yokubona ebusuku: kusukela ekukhetheni inzwa nokuklanywa kwelensi kuya kumandla okukhanyisa, usayizi wendawo evalekile, ngisho nokuphila kwebhethri.
Izinkulumo eziningi mayelana nokubona ebusuku ziqala ngama-LED e-infrared futhi ziphele ngokucutshungulwa kwesiginali yesithombe. Le ndatshana ithatha indlela ehlukile: ibheka ukuzwela kwe-IR njengento ebalulekile yokuklama futhi ilandele imiphumela yako ehlangene kulo lonke uhlelo lwamehlo, lwe-elekthroniki, kanye nemishini. Ukuqonda lezi zihlobo yikho okwehlukanisa ikhamera "esebenza ebusuku" kuleyo ehlinzeka ngezithombe ezisetshenzisekayo ngaphansi kwezimo zangempela zomhlaba, ngenani lezinto elingokoqobo, nangesabelomali samandla esingokoqobo.
Okushiwo Ukuzwela kwe-IR Empeleni (Ngale Kwesibalo Sebhedi Ledatha)
Ngaphambi kokungena ekwakhiweni kwesistimu, kufanelekile ukucacisa ukuthi empeleni sikhuluma ngani lapho sithi “ukuzwela kwe-IR.” Iphepha ledatha yenzwa lingase libonise isibalo sokukhanya okuncane, kodwa lelo nani lodwa alikutsheli cishe lutho mayelana nokusebenza kwangempela kokubona ebusuku. Ukuzwela kwe-IR kwangempela kuyisici esiyinhlanganisela, esinqunywa izici ezimbalwa eziyisisekelo zomzimba zenzwa yesithombe.
Ezingeni eliyisisekelo kakhulu, ukuzwela kuchaza ukuthi isenzwa sisebenza ngempumelelo kangakanani ukuguqula ama-photon e-infrared angenayo abe yishaji kagesi elingalinganiswa. Lokhu kubalwa njengempumelelo ye-quantum (QE), evezwa njengephesenti, kumaza athile. Kumakhamera okubona ebusuku, amaza amabili afanele kakhulu yi-850 nm ne-940 nm, amabhendi e-near-infrared asetshenziswa cishe yizo zonke izinhlelo zokukhanyisa ezisebenzayo. Isenzwa esijwayelekile se-CMOS esikhanyiswe ngaphambili singaba ne-QE engu-30–40% ku-850 nm, kuyilapho ingxenye ekhanyiswe ngemuva enokuzwela okuphezulu ingafinyelela ku-60–70% kulelo wave elilodwa. Lowo mehluko ungase uzwakale mncane, kodwa uhunyushwa ngqo ekutheni ungakanani amandla okukhanyisa owadingayo, noma ukuthi ungabona kude kangakanani ebusuku.
Ikhwalithi ye-Quantum, nokho, iyingxenye kuphela yendaba. Enye ingxenye umsindo. Inzwa ekhiqiza i-dark current eningi noma umsindo wokufunda ingaba ne-QE enhle kakhulu futhi isahlinzeka ngezithombe zasebusuku ezinomsindo, ezingacacile. I-Dark current ingisho eliqoqeka ku-pixel ngayinye ngisho ebumnyameni obuphelele, liqhutshwa imiphumela yokushisa. Likhula ngokushesha okukhulu ngezinga lokushisa, yingakho amakhamera angaphandle ezindaweni ezishisayo evame ukuba nenkinga enkulu ngekhwalithi yesithombe sasebusuku kunalokho okubikezelwa ama-datasheet. Umsindo wokufunda, ngokuphambene, ufakwa njalo lapho inani le-pixel lifundwa kusuka enzweni, futhi uba umthombo womsindo obusayo ngezikhathi zokuchayeka ezimfushane kakhulu.
Yingakho isibalo "se-minimum lux" esikwiphepha ledatha singakhohlisa kangaka. Lelo nani cishe lihlala lilinganiswa ngenzuzo ephezulu kakhulu, isikhathi sokuchayeka eside kakhulu, kanye nezinga lokushisa laselabhorethri elifanele. Emkhiqizweni osetshenzisiwe, awukwazi ukusebenzisa inzuzo ephezulu kakhulu ngaphandle kokucekela phansi imininingwane yesithombe, awukwazi ukusebenzisa isikhathi sokuchayeka esiyimizuzwana eminingi ezintweni ezinyakazayo, futhi nakanjani awukwazi ukulawula izinga lokushisa lendawo. Okubalulekile ngempela ekwakhiweni isilinganiso sesignali kumsindo (SNR) ezingeni elithile lokukhanyisa — futhi lokho kuncike ku-QE, usayizi wephikseli, i-dark current, umsindo wokufunda, kanye namandla egcwele omthombo kusebenza ndawonye.
Kukhona okunye okucashile: ukuzwela akulingani kuyo yonke i-near-infrared band. Inzwa elungiselelwe i-850 nm ingase isebenze kabi ku-940 nm, futhi okuphambene nalokho. Lokhu kudala esinye sezinqumo zokuqala futhi ezinomthelela omkhulu zokuklama: ukuthi iyiphi i-wavelength yokukhanyisa okufanele kusetshenziswe njengenqubo evamile. I-band ye-850 nm inikeza ukuzwela okungcono kwezinzwa cishe kuzo zonke izinzwa ze-silicon — cishe u-30–50% phezulu kwe-QE uma kuqhathaniswa ne-940 nm ezingxenyeni ezijwayelekile. Kodwa ama-emitter angu-850 nm akhiqiza ukukhanya okubomvu okufiphele endaweni ye-LED, okubonakala ngeso lomuntu uma useduze. Ezinhlelweni lapho ukusebenza ngokucashile kubalulekile, i-940 nm ayibonakali neze — kodwa ukhokha ngenxa yalokho kungabonakali ngokuncipha kokuzwela. Lesi sinqumo se-wavelength eyodwa sidlulela emandleni okukhanyisa, i-coating yelensi, ukukhethwa kwezinzwa, futhi ekugcineni ezindlekweni zesistimu.
Ukuhwebelana Okuyisisekelo: Kungani Ukuzwela Okuphezulu Kungenziwa Kube Ngcono Njalo
Isicabango esivamile ukuthi ukuzwela okwengeziwe kuhlala kungcono. Empeleni, ukuzwela kwenzwa kusendaweni yokuhwebelana okunezinhlangothi eziningi okubandakanya ukucaca, amandla, izindleko, ububanzi bokuguquguquka, nokuzinza kokushisa. Ukucindezela kakhulu ekuzweleni kwesinye isici kuvame ukudala izinkinga ezimbi kakhulu kwezinye izindawo.
Ukuzwela vs. Ukucaca
Isigxobo esinamandla kakhulu sokuthuthukisa ukuzwela kwe-IR ukukhulisa usayizi wephikseli. Amaphikseli amakhulu aqoqa ama-photon amaningi, abe namandla aphelele okugcwalisa aphezulu, futhi ngokuvamile anikeza i-SNR engcono. I-physics icacile lapha: konke kufana, iphikseli engu-3 µm iqoqa cishe izikhathi ezingu-2.25 ukukhanya okuningi kunephikseli engu-2 µm ekukhanyeni okufanayo.
Inkinga ukuthi amaphikseli amakhulu asho ukuthi kuncane amaphikseli endaweni yenzwa, noma okunye, i-die yenzwa enkulu futhi ebiza kakhulu ngesisombululo esifanayo. Inzwa ye-1080p enamaphikseli angu-3 µm idinga ifomethi yokukhanya enkulu kakhulu kune-1080p enamaphikseli angu-2 µm, lokho kudinga ilensi enkulu, indawo yokufaka enkulu, kanye nephakethe yenzwa ebiza kakhulu.
Kumikhiqizo eminingi yabathengi kanye nemikhiqizo yevolumu, imakethe idinga kokubili ukucaca okuphezulu kanye nokubona ebusuku okungcono — izinhloso ezimbili ezidonsela ezinhlangothini eziphambene. Amaqembu omklamo avame ukuxazulula lokhu ngokukhetha inzwa enamaphikseli amancane kodwa ukusebenza kahle kwe-quantum okuphezulu (ngokuvamile ingxenye ye-BSI), amukele umsindo ophezulu ukuze agcine ukucaca. Yingakho amakhamera amaningi abathengi e-4K enezici ezinhle kakhulu zasemini kodwa ukusebenza ebusuku okungagculisi: ubukhulu bephikseli bumncane kakhulu ukuba buqoqe ama-IR photon anele.
Ukuzwela vs. Ukusetshenziswa Kwamandla
Amandla avame ukuba umphumela ongacatshangelwa kakhulu ezinkethweni zokuzwela. Kumakhamera asebenza ngebhethri — ama-doorbell, amakhamera asendleleni, amakhamera okuphepha angenantambo — ukuzwela akusiyo inkinga yekhwalithi yesithombe kuqala. Kuyinkinga yempilo yebhethri.
Ikhamera enenzwa yokuzwela ephansi kufanele inxephezele ngokusebenzisa amandla aphezulu e-IR LED, isikhathi sokuchayeka eside, kanye nokuzuza kwenzwa okuphezulu. Amandla aphezulu e-LED adonsa amandla amaningi ngqo. Isikhathi sokuchayeka eside sisho ukuthi inzwa iyasebenza isikhathi esiningi kufreyimu ngayinye, okwandisa ukudonswa kwamandla. Ukuzuza okuphezulu ngokuvamile kudinga ukuncishiswa komsindo wedijithali okunamandla ku-ISP, okwengeza ukusetshenziswa kwamandla okucubungulayo. Umphumela ohlangene ungaba mkhulu kakhulu: isistimu enokuzwela kwe-IR okunguhafu ingase idonse amandla aphindwe kabili noma kathathu kumodi yasebusuku ukuze izuze izinga elifanayo lekhwalithi yesithombe esisebenzayo.
Kumakhamera axhunywe ngezintambo lokhu akubalulekile kangako, kodwa kusathinta ukwakheka kokushisa, ukwehliswa kwezingxenye, nokuthembeka kwesikhathi eside. Kumadivayisi asebenza ngebhethri, ukuzwela kunquma ngqo umjikelezo wokusebenza, ukuziphatha kokuvuka, nokuthi umkhiqizo uyafinyelela yini izimangalo zawo zokuphila kwebhethri ezikhangisiwe.
Ukuzwela vs. Izindleko
Izinzwa ezinokuzwela okuphezulu zibiza kakhulu. Lokhu akubangelwa nje ukuthi zisebenzisa indawo enkulu ye-silicon — nakuba lokho kuyisici — kodwa ngoba izinqubo zokukhiqiza eziletha ukusebenza kahle kwe-quantum ephezulu kanye ne-dark current ephansi ziyinkimbinkimbi futhi zinemiphumela ephansi. Izinzwa ezikhanyiswe ngemuva, isibonelo, zidinga izinyathelo ezengeziwe zokucubungula uma kuqhathaniswa nezingxenye ezikhanyiswe ngaphambili, futhi intengo eyengeziwe ingaba ngu-2× noma ngaphezulu ngesilinganiso esifanayo.
Isithombe sezindleko sinemininingwane eminingi kunenani le-sensor kuphela, nokho. I-sensor enokuzwela okuphezulu inganciphisa izindleko kwezinye izindawo ohlelweni: ama-IR LED ambalwa noma anamandla aphansi, ilensi elula enombobo ohamba kancane, i-ISP enamandla aphansi, kanye ne-heat sink encane. Kwezinye izimo, ukunyukela ku-sensor ebiza kakhulu empeleni kunciphisa izindleko ze-BOM eziphelele ngoba kukhulula imingcele kuzo zonke ezinye izingxenye. Okuhlukile nakho kuyiqiniso: ukukhetha i-sensor eshibhile ukonga ama-dollar ambalwa kungakuphoqa ukuthi ube nohlelo lwe-optical nokukhanyisa olubiza kakhulu.
Ukuzwela vs. Ukuzinza Kokushisa
Izinzwa ezinokuzwela okuphezulu zivame ukuzwela kakhulu ekushintsheni kwezinga lokushisa. I-Dark current icishe iphindeke kabili njalo uma izinga lokushisa lenzwa likhuphuka ngo-6–8 °C, ngakho ikhamera ehlezi elangeni ngqo emini ingabona izinga lomsindo wayo wasebusuku likhuphuka kakhulu kusihlwa. Ekusetshenzisweni kwangaphandle ezindaweni ezinesimo sezulu esishintshashintshayo, lokhu kudala ukuguquguquka kokusebenza okucashile okungavamile ukubonakala kuma-datasheet.
Yingakho izinzwa ezisezingeni lezimboni nezimoto zivame ukucacisa i-dark current ngokushintsha kwezinga lokushisa, nokuthi kungani lezo zingxenye zibiza kakhulu. Emikhiqizweni yabathengi, abaklami bavame ukwamukela ukuhluka kokusebenza kokushisa ukuze bathole izindleko eziphansi — kodwa kufanele baqinisekise ukusebenza ezingeni lokushisa elidlulele, hhayi ezingeni lokushisa legumbi kuphela.
Indlela Ukuzwela Kwe-IR Kulolonga Ukuklanywa Kwe-Optical
Inzwa ayisebenzi yodwa. Uhlelo lwe-optical — ilensi, isihlungi esixhunywe phezulu, kanye nembobo — lunquma ukuthi bangaki bama-photon e-IR atholakalayo afinyelela ngempela ebusweni benzwa. Izidingo zokuzwela ngakho-ke ziqhuba izinqumo ezinkulu zokuklanywa kwe-optical.
Imbobo Nezindleko Zelensi
Inombolo ye-f yeso le-lens ichaza ukuthi ingakanani ukukhanya elingakufaka ku-sensor. I-lens engu-f/1.4 iqoqa ukukhanya okuphindwe kane kune-lens engu-f/2.8. Ku-sensor enokuzwela okuphansi, ukuthola isithombe sasebusuku esisebenzisekayo ngokuvamile kudinga i-lens esheshayo kakhulu — f/1.8 noma eshesha kakhulu — ukuze kunxeshezelwe.
Amalensi asheshayo ayabiza. Adinga izinto eziningi, ukuhlelwa okunembile kakhulu, nobubanzi bengilazi obukhulu. Futhi avamise ukuba nokubukhali okubi emakhoneni, i-chromatic aberration eningi, nokuhlanekezela okukhulu, konke lokhu okufanele kulungiswe ngokubona noma ku-ISP. Ikakhulukazi kumakhamera e-wide-angle, ukuklama ilensi esheshayo ye-f/1.4 enokufana okwamukelekayo kuyo yonke indawo yokubuka kungenye yezinselelo zobunjiniyela ezinzima kakhulu kulo lonke uhlelo.
Inzwa enokuzwela okuphezulu kakhulu iyawephula lo mkhawulo. Uma inzwa izwela ngokuphindwe kabili kumaza e-IR, ungasebenzisa ilensi engu-f/2.0 esikhundleni sika-f/1.4 futhi uthole ukubutha kokukhanya okufanayo. Leyo lensi ehamba kancane izoba shibhile, incane, ibukhali kulo lonke inkambu, futhi ilula ukukhiqiza ngenani elikhulu. Lona ngomunye wemihlomulo yezinhlelo engabonakali kahle yokukhetha inzwa ezwela kakhulu: yenza ukwakheka kwezokubona kube lula kakhulu.
Izembatho ze-IR Nokufanisa Ngokwe-Spectral
Ama-lens awadlulisi ngokulinganayo kuwo wonke amaza obude. Ama-anti-reflective coatings enzelwe amabhendi athile, futhi izinto zengilazi zineempawu zokudlulisa ezihlukene ku-near infrared. Uma isenzwa sakho sinokuzwela okuphezulu ku-850 nm kodwa i-lens coating yakho yenzelwe ukukhanya okubonakalayo, ulahla ingxenye ebalulekile yesabelomali sakho sokuzwela ngaphambi kokuba ama-photon afike ku-silicon.
Yingakho imiklamo ebucayi yokubona ebusuku icacisa amalensi anezembozo ezilungiselwe i-IR ezihambisana nobude begagasi bokukhanyisa. Umehluko phakathi kwesembozo esijwayelekile sokukhanya okubonakalayo nesembozo esilungiselelwe i-850 nm kungaba ukudluliswa okungu-10–20% kubude begagasi elifanele — okwanele ukushintsha isidingo sonke samandla okukhanyisa. Ezinhlelweni ze-940 nm, ukulungiselelwa kwesembozo kubaluleke kakhulu ngoba inzwa isivele ingazweli kahle kulelo bude begagasi; awukwazi ukulahlekelwa amanye ama-photon amaningi elensini.
Isakhiwo Se-IR-Cut Filter
Cishe wonke amakhamera anombala asebenzisa isihlungi se-IR-cut ngesikhathi sokusebenza kwemini ukuvimba ukukhanya kwe-infrared, okungenjalo kungaphazamisa ukuboniswa kombala. Ebusuku, leso sihlungi kufanele sisuswe noma sishintshwe ukuze ukukhanya kwe-infrared kufinyelele inzwa. Indlela evame kakhulu isihlungi se-IR-cut esingumshini (ICR) esishelela ngokomzimba esinye sezihlungi ezimbili endleleni yokukhanya.
Ukuzwela kwenzwa kuthonya ngqo ukuthi udinga i-ICR nhlobo yini, nokuthi yiluphi uhlobo olusebenzisayo. Izinzwa ezinokuzwela okuphezulu kakhulu ngezinye izikhathi zinganikeza ukusebenza ebusuku okwamukelekayo ngisho noma isihlungi se-IR-cut sisetshenziswa, kuqede indlela yemishini futhi kuthuthukise ukuthembeka. Ezakhiweni eziningi, nokho, i-ICR iyimpoqo — kodwa izici zokudlulisa zesihlungi semodi yasebusuku zikhethwa ngokusekelwe kujika lokuzwela kwenzwa.
Kukhona futhi indlela ephakathi esafufusa: izinzwa ze-“day-night” ezingenasihlungi esinyakazayo, ezisebenzisa iphethini yesihlungi samazinga ephikseli edlulisa kokubili ukukhanya okubonakalayo ne-IR. Lokhu kushintshanisa ukunemba kombala wasemini ukuze kube nemishini elula nokuthembeka okungcono. Ukusebenza kwazo kwangempela ebusuku kuncike kakhulu ekutheni isihlungi sidlulisa malini ukukhanya kwe-IR — esinye isimo lapho ukuzwela kwenzwa eluhlaza kuyingxenye yesibalo kuphela.
Ukulingana Komkhawulo
Enye into evamile yokukhanya engabonwa kalula i-vignetting kubhendi ye-infrared. Amalensi amaningi anokulingana okuhle kokukhanya okubonakalayo abonisa ukwehla okukhulu kokukhanya emakhoneni uma esetshenziswa ku-850 nm noma ku-940 nm. Lo mphumela uba kubi kakhulu ngezimbobo ezisheshayo kanye nezinkambu ezibanzi zokubuka.
Nge-sensor enokuzwela okuphezulu, i-vignetting yamakhona elinganiselayo iyamukeleka ngoba isikhungo sesithombe sisenayo i-SNR eningi, futhi amakhona angalungiswa ngedijithali. Nge-sensor enokuzwela okuphansi, amakhona angase ehle ngaphansi kwezinga lomsindo elisetshenzisekayo ngokuphelele, okuholela emakhoneni amnyama ebusuku. Lokhu kuphoqa abaklami be-optical ukuthi basebenzise umklamo we-lens olinganayo kakhulu (futhi obiza kakhulu), noma bangeze amandla okukhanyisa engeziwe emaphethelweni enkambu — okudala izinkinga zayo ngamachashaza ashisayo nokusetshenziswa kwamandla.
Ukwakhiwa Kokukhanya: Olunye Uhlangothi Lwesibalo Sokuzwela
Ukukhanya kwe-infrared okusebenzayo yikho okwenza amakhamera amaningi okubona ebusuku asebenze. Ubudlelwano phakathi kokuzwela kwenzwa nokwakhiwa kokukhanya buqondile: yonke i-decibel yokuzwela oyitholayo ohlangothini lwenzwa iyidecibel yamandla okukhanya ongayisusa ohlelweni. Yilapha lapho izinqumo zokuzwela zinemithelela ebonakalayo yezindleko nosayizi.
Amandla kanye Nenani Lama-emitha
Indlela elula yokucabanga ngayo mayelana nesabelomali samandla okukhanya. Ebangeni elithile lesigcawu kanye nokukhanya kwesithombe okufunwayo, kunenani elinqunyiwe lama-photon e-IR okudingeka ukuthi abonakale esigcawini futhi abuyele kukhamera. Uma i-sensor inokuzwela okuphindwe kabili, udinga ama-photon angaphelele kanye nengxenye afika kulensi. Uma kubalwa konke ukulahlekelwa ohlelweni — ukuncipha komoya, ukulahlekelwa kokubonakala, ukudluliswa kwelensi — lokhu kuhumusha cishe kumandla okukhanya angaphelele kanye nengxenye.
Ukwehlisa amandla okukhanyisa kunemiphumela emihle elandelanayo. Ungasebenzisa ama-LED ambalwa, ama-heat sink amancane, i-electronics yokushayela elula, kanye namandla kagesi amancane. Kumakhamera abathengi, lokhu ngokuvamile kusho umehluko phakathi komklamo ongena endlini ekhompakthi kanye nomklamo odinga indawo enkulu yokukhipha ukushisa. Kumadivayisi asebenza ngebhethri, kungaphinda kabili noma kathathu impilo yebhethri kumodi yasebusuku.
Iphendulwa kabusha kwe-Wavelength: 850 nm vs. 940 nm
Sikhulume ngaphambili ngegebe lokuzwela phakathi kuka-850 nm no-940 nm. Leli gebe liyisici esiyinhloko esinqumayo ekukhetheni i-wavelength.
Ku-850 nm, izinzwa ze-silicon ezijwayelekile zine-QE ephezulu kakhulu, futhi ama-IR LED nawo asebenza kahle kakhulu ekuguquleni amandla kagesi abe umphumela wokukhanya. Le nhlanganisela isho ukuthi uhlelo lwe-850 nm lungakwazi ukunikeza ukukhanya kwesigcawu okufanayo ngamandla kagesi amancane kakhulu. Okubi ukukhanya okubomvu okuncane okubonakala ngeso lomuntu, okungamukeleki ekuqapheni okuyimfihlo futhi okungafuneki kumakhamera abathengi abaseduze nezindawo zokuhlala.
Ku-940 nm, ama-LED awakhiqizi mkhanya obonakalayo nhlobo — kodwa i-QE yenzwa yehla cishe ngo-30–50% ezingxenyeni eziningi, futhi ukusebenza kahle kwe-LED wall-plug nakho kuyehla. Umphumela uwukuthi uhlelo lwe-940 nm ludinga cishe amandla kagesi aphindwe kabili ukuze kuzuzwe ukukhanya kwesithombe sasebusuku okufanayo njengohlelo lwe-850 nm olulinganayo. Lomehluko mkhulu kakhulu. Amaqembu okuklama ashintsha ukusuka ku-850 nm aya ku-940 nm ngenxa yezizathu zokubukeka kwangaphandle avamisile ukungakuboni ukuthi kufanele bacindezela kangakanani uhlelo lokukhanyisa, nokuthi kufanele balawule ukushisa okungakanani.
Izinzwa ezinokuzwela okuphezulu zinciphisa leli gebe. Uma ukhetha inzwa enokuphendula okuhle kakhulu ku-940 nm — ezinye izingxenye ezikhethekile zenzelwe leli bhendi — unganciphisa kakhulu inani lamandla adingekayo. Lesi ngesinye sezizathu ezivame kakhulu zokuthi abaklami banyusele ezingxenyeni zezinzwa ezisezingeni eliphezulu: hhayi ukuthola ukusebenza okungcono ku-850 nm, kodwa ukwenza ukukhanya kwe-940 nm kusebenze ngaphakathi kwesabelomali samandla esifanelekile.
I-engeli ye-Beam kanye nokufana
Ukufana kokukhanyisa kuchaza ukuthi ukukhanya kwe-IR kusibekela kahle kangakanani isigcawu. Ukungafani okubi kubangela indawo ekhanyayo ephakathi nendawo yesithombe kanye namakhona amnyama.
Ngokumangalisayo, izinzwa ezinokuzwela okuphansi zenza ukufana kube nzima kakhulu ukukufeza. Lapho inzwa iseduze nezinga layo lomsindo emaphethelweni esithombe, ngisho nokuhluka okuncane kokukhanya kwenza umehluko omkhulu wokukhanya obonakalayo. Ngenzwa ezwela kakhulu, sonke isithombe siba ngaphezu kwezinga lomsindo ngezinga elikhululekile, ngakho ukuhluka kokukhanya akubonakali kakhulu.
Lokhu kusho ukuthi amasistimu anokuzwela okuphezulu angasebenzisa ama-optics okukhanyisa alula, angabizi kakhulu — ama-reflector ajwayelekile noma ama-diffuser esikhundleni samalensi e-free-form abunjwe ngokunemba. Ikakhulukazi kumakhamera e-wide-angle, lokhu kuyonga izindleko okuphawulekayo.
Ibanga Nebanga Lokutholwa
Ibanga lokubona ebusuku lingenye yezincazelo ezimakethwa kakhulu futhi ezingaqondwa kahle. Ibanga eliphezulu lapho ikhamera ingathola noma ibone into ebusuku lincike ezintweni eziningi, kodwa ukuzwela kwenzwa kuyisisekelo.
Umthetho ojwayelekile wokucabangela ukuthi ukuphinda kabili ukuzwela kwandisa ibanga lokutholwa elisebenzisekayo cishe nge-40%, uma kucatshangwa ukuthi amandla okukhanyisa ahlala efanayo. Lokhu kuvela emthethweni wesikwele esiphambene: amandla okukhanyisa ehla ngesikwele sebanga, ngakho-ke ukuze ubone ibanga elingama-40% kude kakhulu udinga cishe ukuphinda kabili ukuzwela (noma ukuphinda kabili amandla). Yingakho amakhamera asebenzela ibanga elide ezimbonini kanye nasemngceleni cishe wonke esebenzisa izinzwa ezinkulu zamaphikseli, ezinokuzwela okuphezulu ezihambisana nokukhanyisa kwe-IR okunamandla aphezulu. Awukwazi ukuthola ukubona ebusuku kwamakhilomitha angu-100+ kusuka kunzwa encane yamaphikseli yomsebenzisi, kungakhathaliseki ukuthi mangaki ama-LED owafaka ngaphambili.
I-ISP Nokucutshungulwa Kwesithombe: Ukunxephezela Imikhawulo Yokuzwela
Akukho ngxoxo ngokwakhiwa kokubona ebusuku ephelele ngaphandle kwesicubunguli sesignali yesithombe. I-ISP ayikwazi ukudala amaphothoni angakaze aqoqwe, kodwa ingathuthukisa kakhulu izinga elibonakalayo lesithombe sokukhanya okuphansi — futhi ngokwenza lokho, ishintsha ukuthi kungakanani ukuzwela kwenzwa elikudingayo empeleni.
Amasu Okunciphisa Umsindo
Ukunciphisa umsindo wedijithali (DNR) iyithuluzi eliyinhloko lokuthuthukisa izinga lesithombe ekukhanyeni okuphansi. I-2D DNR isebenza ngaphakathi kwefreyimu eyodwa, icwecisa umsindo ngenkathi izama ukugcina imiphetho. I-3D DNR, noma ukunciphisa umsindo kwesikhathi, ihlanganisa ulwazi kumafreyimu amaningi ukuze icindezele umsindo ngamandla amakhulu.
I-Temporal DNR isebenza kahle kakhulu — ingathuthukisa i-SNR esebenzayo nge-6 dB noma ngaphezulu, okulingana nokuphindwe kane kokuzwela kwenzwa noma ukuphindwe kane kwamandla okukhanyisa. Kodwa iza nokushintshana. Izinto ezinyakazayo zishiya imikhondo yezipoki, ukunyakaza okusheshayo kungafiphalisa, futhi i-algorithm idinga ukulungiswa ngokucophelela kwesimo ngasinye sokusetshenziswa. Ezigcawini ezinganyakazi (ezokuphepha zasendlini, ukuqapha indawo ezungezile) isebenza kahle kakhulu. Ezigcawini ezinokunyakaza okusheshayo (amakhamera omgwaqo, amakhamera omzimba) ayisebenzi kahle kangako.
Lokhu kudala ukusebenza okuthakazelisayo komklamo: ezinhlelweni zezimo ezinganyakazi, ngokuvamile ungasebenzisa inzwa enokuzwela okuphansi futhi uncike ku-3D DNR ukubuyisela umehluko. Ezinhlelweni zokunyakaza okuphezulu, awukwazi — udinga ukuzwela kwangempela okuvela enzweni ngokwayo. Amathimba amaningi emikhiqizo afunde lokhu ngendlela enzima, ecacisa inzwa eshibhile ecabanga ukuthi isofthiwe izolungisa umsindo, kodwa bathola ukuthi ukugqama kwesithombe esinyakazayo akwamukeleki esimweni sabo sokusebenzisa.
Ukuchayeka kanye Nesilinganiso Sesikhathi Sokuthwebula
Enye indlela yokunxephezela ukuzwela okuphansi ukwandisa isikhathi sokuchayeka. Ukuchayeka isikhathi eside kuqoqa ama-photon amaningi, kuthuthukise i-SNR ngezindleko ze-frame rate kanye nokufiphala kokunyakaza.
Kumakhamera adinga kuphela ukuthwebula izithombe ezinganyakazi ngo-10–15 fps, ukukhanya isikhathi eside kuyisinqumo esingcono. Kumakhamera adinga u-30 fps noma ngaphezulu, noma adinga ukumisa ukunyakaza, isikhathi sokukhanya sincishiswa yisikhathi sefreyimu. Ikhamera engu-30 fps inesikhathi esiphezulu sokukhanya esingaba ngu-33 ms ngefreyimu — futhi empeleni sincane kakhulu, ngoba inzwa idinga isikhathi sokufunda.
