Kameras na RGB-IR: An yi shi ke? Da ke nanan mai tsawaccen su?

Kamara modula daga wannan kasa na yi aiki da CFAs (Color Filter Arrays) dai dai ne BGGR wani an saukar da shirin na hanyar mai gudunwa da IR (Infrared). Kuma, ya fiye taimakon hanyar da ke nuna IR, yana soya mutuwa da cikin rubutuwar hanyar RGB. Suna za'a soya masu amfani da IR cikin hanyar da aka samu.
 
Don zaiyance wannan masu, kamara suka iya aikawa filtar jikin IR don bayyana IR light ta gabatarwa daya. Tare da layi, suka iya tambayoyi kawai don ake samun IR light don bincika gabatarwa. Maisu, tambaya na mashinaiya ne kawai ne kan sha'awa, ya kamata matsayin module kamara.
 
Kamara RGB-IR ya biyu wannan kalmomin daidai ne yanzu a cikin samfiri mai amfani da sabon fittin jajjakin litafiya (CFA) yan yi daga pixels talaka da pixels mai hanyar IR. Suna mai watsalar daidai yana zama a cikin samfiri na litafiya da samfiri na IR binciken mutane, kuma ya kawo daidai da haifarwa litafiya. Pixels talaka da aka iya abubuwan imaging multi-band.
 
A cikin rubutun na farko nan, mutum akan shiga masu riga ake yi amfani da kamara modula RGB-IR da komponentinsa, kuma suna masu halifin vision embedded ake yi amfani da kamara RGB-IR binciken mutane suka recommended don kamara kawai.

An yi kamara RGB-IR?

Pixel mai formattin Bayer standard na mode BGGR ya fiye ta bar bar.

Pixels mai amfani da aka yi kamara RGB-IR yana iya tsaye rayuwanci na IR a cikin uwar sa. Kuma pixels sai an yi imaging multi-band. Sabon CFA mai amfani da pixels R, G, B da IR ya fiye ta bar bar:

Sunan wannan ne ba hanyar amfani da kamara RGB-IR:

• An yi amfani daidai don an sanya a cikin shirin kuma wataƙasa daya na rana da layi. An kawai daga wannan aiki don wataƙasa gaba-dabba'a.
• Kunna amfani da fiter mekaniki don an zama bayan rayuwa naɗan rayuwar IR, ya kawo hanyar da suka gabatar da cikakken aikin da.
• An kawo rubutu mai amfani da rayuwar IR da an samfuka wannan data talaka da data rayuwar IR. An kawo amfani daidai don an samun makamafin rayuwar IR a cikin RGB da an bincika color don an saukar daidai na RGB

Hakanan na amfani da rayuwar visible na infrared CFA

Kuna amfani da fiter RGB-IR ba yake amfani daidai ba. An kawo amfani da komponan da aka samun amfani da RGB-IR

Sensar: Bincika sensor da aka samun pixels mai amfani da IR a cikin CFA. Mai riga onsemi da OmniVision an kawo sensors mai amfani da RGB-IR
 
Optics: Ayyukan kamera na rayuwanci aka samun IR cutoff filters don guda mara a cikin 650nm. Don hanyar imaging RGB-IR, filtar dual bandpass, mai so daidaita ne daga wannan a kan filtar IR cutoff tradishenali.
 
Image Signal Processor (ISP): ISP an yi algorizam mai wanda da data RGB yanuwar IR a cikin frames kuma, an sani output RGB dai dai, kuma an shigar da kontaminashin IR don kai fara littafin warna. Kamar shi, ISP ya kamata yi amfani da processed RGB ko frames IR duk da yadda system host an samun.

Amfani Common Embedded Vision don Camera RGB-IR

Automatic Number Plate Recognition (ANPR)

Don ANPR, mai so daidaita na farko jami'in rubutu, simbul, kuma warna a cikin shirin tara abubuwa rayuwarsa, amfani cameras RGB-IR mai so daidaita ne don kai fara littafin images visible kuma infrared don hanyar longa kuma bayan tunani.

Security Weatherproof Advanced

Za'a RGB-IR cameras, amfani da aikin security yana gudanarwa cikakken littafin na wannan daga cikakken an yi shirya wanda kuma ya saita masu babban gabatarwa. Duniya ko layi, yadda kamataci ne, ake samun sensors na RGB-IR da filtar bayan dual bandpass ta samun fayil mai kyau dai dai a zai iya samun mafi tabbatarwa da aka samunwa don analysis.
 
Sinoseen yana haifarwa su da rubutu da aka sona, kuma suna daidaita za'a iya samunwa misali suna daidaita za'a iya samunwa daga problem yadda aka samunwa a hanyar visible da infrared (IR) imaging.
