Umehluko phakathi kwelensi ye-IR nelensi evamile
Uma ilensi evamile isebenzisa ukukhanya kwe-infrared ebusuku, indawo yokugxila kuyoshintsha.Yenza isithombe sifiphaze futhi sidinga ukulungiswa ukuze sicace.Ukugxila kwelensi ye-IR kuyahambisana kukho kokubili ukukhanya kwe-infrared nokubonakalayo.Kukhona namalensi e-parfocal.2. Ngenxa yokuthi izosetshenziswa ebusuku, indawo yokuvula kufanele ibe nkulu kunaleyo yamalensi avamile.Imbobo ibizwa ngokuthi imbobo ehlobene, imelelwa ngu-F, ngokuvamile u-f omkhulu, omelela ubuhlobo phakathi kobubanzi obusebenzayo belensi nobude bokugxila.Inani elincane, umphumela uba ngcono.Ubunzima obukhulu, intengo iyanda.Ilensi ye-IR ilensi ye-infrared, esetshenziswa kakhulu ukubona ebusuku, futhi isetshenziswa kakhulu kumakhamera agadayo.
Ilensi ye-IR
Ngemuva kokuthi ilensi ye-CCTV ilungiswe kahle emini, ukugxila kuyoshintsha ebusuku, futhi kufanele kugxilwe ngokuphindaphindiwe emini nasebusuku!Ilensi ye-IR isebenzisa izinto ezikhethekile zokubona, futhi i-multi-layer coating isetshenziswa kuyunithi ngayinye yelensi ukuze kwandiswe umthelela wezinguquko zokukhanya emini nasebusuku.Asikho isidingo sokuphindaphinda ukulungisa amalensi e-IR kungenye indawo ebalulekile yokuthuthukiswa kwemikhiqizo yelensi engenisiwe eminyakeni yamuva nje, okuwukuhlangabezana nesidingo semakethe sokuqapha amahora angama-24.Ngobunzima obukhulayo bokuvikeleka komphakathi, abantu abadingi nje kuphela ukuthi amakhamera akwazi ukuqedela imisebenzi yokugada emini, kodwa futhi akwazi ukuba nesibopho somsebenzi wokuphepha ebusuku, ngakho ukusetshenziswa kwamakhamera wemini nobusuku kuzokwanda kakhulu. adumile, namalensi e-IR angumsizi omuhle wamakhamera asemini nasebusuku .
Njengamanje, imikhiqizo yekhamera yemini nobusuku yaseChina ikakhulukazi isebenzisa izihlungi ze-infrared ukufeza ukuguqulwa kwemini nobusuku, okungukuthi, ukuvula izihlungi emini ukuze kuvinjwe imisebe ye-infrared ukuthi ingangeni ku-CCD, ukuze i-CCD ikwazi ukuzwa ukukhanya okubonakalayo kuphela;ngaphansi kombono wasebusuku, izihlungi ziyeka ukusebenza , Azisavimbeli imisebe ye-infrared ukuthi ingangeni ku-CCD, futhi imisebe ye-infrared ingena ku-lens ukuze ifane nesithombe ngemva kokuboniswa izinto.Kodwa ekusebenzeni, ngokuvamile kwenzeka ukuthi isithombe sicacile phakathi nosuku, kodwa isithombe sifiphazwa ngaphansi kwezimo zokukhanya kwe-infrared.
Lokhu kungenxa yokuthi ubude bamaza okukhanya okubonakalayo nokukhanya kwe-infrared (ukukhanya kwe-IR) kuhlukile, futhi ubude beza beza obuhlukene buzoholela ezindaweni ezihlukene zendiza egxilile yesithombe, okuholela ekugxilweni okubonakalayo nezithombe ezifiphele.Ilensi ye-IR ingalungisa ukuphuma okuyindilinga, ivumele imisebe yokukhanya ehlukene ukuthi igxile endaweni efanayo yendiza egxile kuyo, ngaleyo ndlela yenza isithombe sicace futhi sihlangabezane nezidingo zokugadwa ebusuku.
