Ziziphi izinto eziluncedo kwiilensi zeBi-telecentric? Umahluko phakathi kweBi-telecentric Lens kunye neTelecentric Lens

A i-bi-telecentric lensI-lens eyenziwe ngezinto ezimbini ze-optical index kunye neempawu ze-dispersion ezahlukeneyo. Injongo yayo ephambili kukunciphisa okanye ukuphelisa ukungahambi kakuhle, ngokukodwa ukuchithwa kwe-chromatic, ngokudibanisa izinto ezahlukeneyo ze-optical, ngaloo ndlela kuphuculwe umgangatho we-imaging ye-lens.

1,Ziziphi iingenelo ze-bi-iilensi zocingo?

Iilensi zeBi-telecentric zineenzuzo ezininzi ezibalaseleyo, kodwa zikwanzima kakhulu ukusebenza kwaye zifuna izakhono ezingaphezulu zokuzisebenzisa. Makhe sijonge kwiingenelo zee-bi-telecentric lens ngokweenkcukacha:

1)Yenza imbonakalo ekhethekileyo

Iilensi ze-Bi-telecentric zingenza iziphumo ezibonakalayo ezingenako ukufezekiswa ngeelensi eziqhelekileyo, ezifana nokulungelelanisa ngokugqithisileyo ubunzulu bentsimi kunye nokudala into ebizwa ngokuba yi "imodeli encinci".

2)Lawula imbono yomfanekiso

I-lens ye-bi-telecentric inokulawula imbono yomfanekiso, ilungise ukugqwesa imiphetho yesakhiwo, kwaye igcine imigca eqikelelweyo ngokuthe tye ngaphandle kokugoba.

3)Yenza ulawulo lokugxila

Iilensi ze-Bi-telecentric zivumela uhlengahlengiso oluzimeleyo lokugxila kunye nobunzulu bendiza, engenakwenzeka ngeelensi eziqhelekileyo ezisisigxina.

4)Umgangatho womfanekiso ogqwesileyo

Ngenxa yoyilo lwabo,iilensi ze-bi-telecentriczikholisa ukuba nokusebenza okugqwesileyo kwamehlo kunye nomgangatho womfanekiso.

5)Ukuguquguquka kokusebenza

Nangona iilensi ze-bi-telecentric zifuna ukusebenza ngesandla kunye nokulawula, zibonelela ngeqondo lokuguquguquka elivumela umfaki-zithombe ukuba alawule umfanekiso ngokweemfuno ezithile.

6)Ukusungula iziphumo ezahlukeneyo

Ngokuhlengahlengisa i-tilt kunye ne-offset ye-lens, abafoti banokudala iintlobo ezahlukeneyo zeziphumo ezahlukeneyo ngeelensi ze-bi-telecentric.

2,Umahluko phakathi kwe-bi-ilensi yocingo kunye nelensi yocingo

Umahluko omkhulu phakathi kwe-bi-telecentric lens kunye ne-telecentric lens kukukwazi ukulungisa i-engile ye-lens kunye nokuhambisa ilensi:

1)I-Bi-telecentric lens

Iilensi zeBi-telecentric ngokubanzi zibhekisa kwiilensi zetelecentric ezineelensi ezimbini ezinokuhlengahlengiswa ngokwahlukeneyo. Bangakwazi ukunyuka naphantsi (i-offset) kwaye ekhohlo kwaye ekunene (sway), kwaye banokutshintsha i-angle ye-tilt.

Uyilo lwelensi ye-bi-telecentric inika abafoti bezithombe ulawulo olukhulu kunye nenkululeko yokuyila, kodwa kwangaxeshanye kunzima kakhulu ukusebenza, kufuna itekhnoloji ephezulu kunye nobuchule obugqwesileyo.

Ngokubanzi, iilensi ze-bi-telecentric zinika inkululeko enkulu yokulawula kwaye zenze imifanekiso enobuchule obungakumbi kwaye ibe nesibheno esihlala sihleli, kodwa nazo ziza nexabiso eliphezulu kunye neemfuno zobugcisa ekunzima ukuziqonda.

2)Iilensi zeTelecentric

Iilensi zeTelecentricvumela abafoti ukuba bahlengahlengise i-angle ye-lens ukwenzela ukuba i-lens kunye ne-sensor ingasahambelani, ivumela umfoti ukuba alawule ubunzulu bengqwalasela kwaye enze iziphumo ezinamandla kunye nokudala.

Ngakolunye uhlangothi, i-lens ye-telecentric lens nayo inokushukunyiswa okanye "i-offset," iguqule ukubunjwa ngaphandle kokutshintsha i-angle yekhamera, enenzuzo yokulawula kunye nokulungisa imbono.

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.
