Izinto eziluncedo kunye nokungalunganga kweeLensi zeTelecentric, umahluko phakathi kweeLensi zocingo kunye neeLensi eziqhelekileyo

Iilensi zeTelecentric, ekwaziwa ngokuba ziilensi ze-tilt-shift okanye iilensi ezigxilwe ngokuthambileyo, zineyona nkalo ibalulekileyo yokuba imilo yangaphakathi yelensi inokuphambuka kumbindi wokukhanya wekhamera.

Xa i-lens eqhelekileyo idubula into, i-lens kunye nefilimu okanye i-sensor ikwi-plane enye, ngelixa i-telecentric lens inokujikeleza okanye i-tilt isakhiwo se-lens ukwenzela ukuba i-optical center ye-lens iphambuke kumbindi we-sensor okanye ifilimu.

1,Iingenelo kunye nokungalunganga kweelensi zocingo

I-Advanteji 1: Ubunzulu bolawulo lwangaphandle

Iilensi zeTelecentric zinokujolisa ngokukhethekileyo kwiindawo ezithile zomfanekiso ngokutshintsha i-angle ethambekileyo yelensi, ngaloo ndlela ivumela abafoti ukuba benze iziphumo ezikhethekileyo zokugxila, ezifana nesiphumo seLillipuian.

Inzuzo yesi-2: Imbonocukulawula

Enye yeenzuzo eziphambili zeelensi zocingo kubafoti bokwakha kukuba zibonelela ngolawulo olukhulu kwimbono. Iilensi eziqhelekileyo zinokubangela ukuba imigca ethe tye ekufotweni (efana nemigangatho epakiweyo yesakhiwo) ibonakale igoso, kodwa iilensi zetelecentric zinokutshintsha umgca wokubonwayo ukuze imigca ibonakale ithe tye okanye iqhelekile.

I-Advantage yesi-3: I-engile yokujonga yasimahla

Iilensi zeTelecentric ziyakwazi ukwenza ii-engile ezahlukeneyo zasimahla zokujonga (okt iimbono ezingahambelaniyo nesivamvo). Ngamanye amazwi, ukusebenzisa ailensi yocingoikuvumela ukuba ubambe indawo ebanzi yokujonga ngaphandle kokuhambisa ikhamera, eluncedo kakhulu kubafoti bezakhiwo kunye nembonakalo yomhlaba.

Ilensi yocingo

Ububi 1: Ukusebenza okuntsonkothileyo

Ukusebenzisa kunye nokufunda iilensi zetelecentric kufuna izakhono ezikhethekileyo kunye nokuqonda okunzulu kokufota, okunokuba nzima kwabanye abafoti abaqalayo.

Ububi 2: Kuyabiza

Iilensi zeTelecentric zibiza kakhulu kuneelensi eziqhelekileyo, ezinokuba lixabiso abanye abafoti abangakwaziyo ukulamkela.

Ububi 3: Ukusetyenziswa kunqongophele

Nangonaiilensi zocingoziluncedo kakhulu kwiimeko ezithile, ezinjengokufota kwezakhiwo kunye nokufota komhlaba, ukusetyenziswa kwazo kunokuncitshiswa kwezinye iimeko, ezifana nokufota, ukufota, njl njl.

2,Umahluko phakathi kweelensi zocingo kunye neelensi eziqhelekileyo

Owona mahluko mkhulu phakathi kweelensi zocingo kunye neelensi eziqhelekileyo ulele kule miba ilandelayo:

Ubunzulu bolawulo lwentsimi

Kwilensi eqhelekileyo, inqwelomoya yogxininiso ihlala ihambelana nenzwa. Kwilensi yocingo, unokuthambeka ilensi ukuze utshintshe le nqwelo-moya, ukuze ukwazi ukulawula ukuba yeyiphi indawo yomfanekiso ebukhali kwaye yeyiphi indawo yomfanekiso emfiliba, ikunika ulawulo olukhulu kubunzulu bebala.

Izicelo zokufota iilensi zeTelecentric

Ukushukuma kweLens

Kwilensi eqhelekileyo, i-lens kunye ne-sensor yomfanekiso (njengefilimu yekhamera okanye i-digital sensor) zihlala zihambelana. Kwilensi ye-telecentric, iinxalenye zelensi zinokuhamba ngokuzimeleyo kwikhamera, zivumela umgca wokujonga lens ukuba uphambuke kwindiza yoluvo.

Le nature ehambayo yenzaiilensi zocingoinkulu yokufota izakhiwo kunye nembonakalo yomhlaba, njengoko itshintsha imbono kwaye yenza imigca ibonakale ngokuthe tye.

Ixabiso

Iilensi zeTelecentric zibiza kakhulu kuneelensi eziqhelekileyo ngenxa yeenkcukacha zolwakhiwo kunye nokusetyenziswa kwayo.

Aukugrumba

Iilensi zeTelecentric ngokubanzi zifuna ukuxhotyiswa ngomkhala omkhulu, oluncedo ekudubuleni kwiindawo ezinokukhanya okuphantsi.

Kufuneka kuqatshelwe ukuba nangonaiilensi zocingoinokudala iziphumo ezibonwayo ezizodwa, zinzima kakhulu ukuzisebenzisa kuneelensi eziqhelekileyo kwaye zifuna izakhono eziphezulu kumsebenzisi.

Iingcamango Zokugqibela:

Ukuba unomdla wokuthenga iintlobo ezahlukeneyo zeelensi zokubek' esweni, ukuskena, iidrone, ikhaya elinobulumko, okanye naluphi na olunye usetyenziso, sinayo into oyifunayo. Qhagamshelana nathi namhlanje ukuze ufunde ngakumbi malunga neelensi zethu kunye nezinye izincedisi.
