Kuyini ukuhlanekezela kwelensi?

Lokhu kuyinkinga emkhakheni we-optics, enencazelo yayo ejwayelekile kuma-optics.Isithombe esidalwe ngokuthatha isithombe ngekhamera sizohlanekezelwa.

Njengesibonelo, sonke sinolwazi lokuthatha izithombe ngamakhamera ajwayelekile.Kukhona ilensi ebizwa ngokuthi “wide-angle lens”, eyaziwa nangokuthi “i-fisheye lens”, enalolu hlobo lwelensi yokuthatha izithombe, uzothola ukuthi isithombe ezinhlangothini ezine zesithombe sigobile.Lesi simo sibangelwa "ukuhlanekezela kwamalensi".Isibonelo sokuthi “fisheye lens” ngoba “fisheye lens” iyilensi enkulu yokuhlanekezela.

Amalensi abe nokuhlanekezela, umehluko kuphela ukuhlanekezela kukhulu futhi kuncane.Futhi ohlelweni lokuhlola okubukwayo, yiqiniso, ithemba lokuthi ukuhlanekezela kwe-lens kuncane ngangokunokwenzeka.Lokhu kungenxa yokuthi isistimu yokubona ukuze kutholwe, isesithombeni sekhamera.Uma isithombe sekhamera "esigwegwini", imiphumela yokutholwa kwesistimu ngeke "ilunge" .
Kunezindlela ezimbili zesistimu ye-Vision yokulungiswa kokuhlanekezelwa kwamalensi.

(1) Kusuka ku-hardware:

Ngelensi encane kakhulu yokuhlanekezela.Le lens ibizwa ngokuthi i-telecenter imaging lens.Kodwa intengo yayo ibiza izikhathi ezingu-6 noma ngaphezulu njengentengo yamalensi avamile.Iningi lokunemba okuphezulu kwesistimu yokulinganisa okubukwayo, enamalensi anjalo.

(2) Kusuka ku-software:

“Ekulinganisweni kwekhamera”, ukusetshenziswa kwemojuli evamile yokulinganisa ku-matrix yechashazi ukuze kubalwe.
Indlela eqondile yilena: ngemva kokuqedwa “kokulinganisa kwekhamera”, ngokwesilinganiso esaziwayo sosayizi wephoyinti ngalinye ku-matrix yamachashazi, ukuhlaziya usayizi wamaphoyinti endaweni ezungezile ye-matrix yamachashazi, kanye nosayizi we-matrix yamachashazi. amaphuzu endingilizini yangaphakathi ye-matrix yamachashazi ahlukile.Ngokuqhathanisa kungenziwa etholakala isilinganiso, lesi silinganiso ukuhlanekezela lens.Ngalesi silinganiso, esilinganisweni sangempela singenziwa ukulungisa ukuhlanekezela

I-Ronghua, ingumkhiqizi onguchwepheshe be-R&D, ukwenza ngokwezifiso, ukukhiqizwa, ukuthengisa kanye nensizakalo yamamojula wekhamera, amamojula ekhamera ye-USB, amalensi neminye imikhiqizo.Uma unentshisekelo yokuxhumana nathi, sicela:
