Yintoni ukugqwesa ilensi?

Le yingxaki kwintsimi ye-optics, enenkcazo yayo esemgangathweni kwi-optics.Umfanekiso owenziwe ngokuthatha umfanekiso ngekhamera uya kuphazamiseka.

Njengomzekelo, sonke sinamava okuthatha imifanekiso ngeekhamera eziqhelekileyo.Kukho i-lens ebizwa ngokuthi "i-wide-angle lens", eyaziwa ngokuba yi "fisheye lens", kunye nolu hlobo lwelensi ukuthatha imifanekiso, uya kufumanisa ukuba umfanekiso kumacala amane esithombeni ugobile.Esi siganeko sibangelwa "i-lens distortion".Umzekelo wokuthi "i-lens ye-fisheye" kuba "i-lens ye-fisheye" yi-lens enkulu yokuphazamiseka.

Iilensi zinokuphazamiseka, umahluko kuphela ukugqwetheka kukhulu kwaye kuncinci.Kwaye kwinkqubo yokuhlola ebonakalayo, ngokuqinisekileyo, ithemba lokuba ukuguqulwa kwe-lens kuncinci kunokwenzeka.Oku kungenxa yokuba isixokelelwano sombono sokubona, sisemfanekisweni womfanekiso wekhamera.Ukuba umfanekiso wekhamera kwi "goso", ngoko iziphumo zokufumanisa inkqubo aziyi kuba "zifanelekileyo".
Kukho iindlela ezimbini zenkqubo yeVision yokulungiswa kokuphazamiseka kwelensi.

(1) Ukusuka kwihardware:

Ngelensi encinci kakhulu yokuphazamiseka.Le lens ibizwa ngokuba yi-telecenter imaging lens.Kodwa ixabiso layo libiza njenge-6 amaxesha okanye ngaphezulu njengexabiso le-lens eziqhelekileyo.Uninzi lokuchaneka okuphezulu kwenkqubo yokulinganisa okubonakalayo, kunye neelensi ezinjalo.

(2) Ukusuka kwisoftware:

Kwi "calibration yekhamera", ukusetyenziswa kwemodyuli yomgangatho wokulinganisa kwimatrix yamachaphaza ukubala.
Indlela ekhethekileyo yile: emva kokugqitywa "kokulinganisa ikhamera", ngokomlinganiselo owaziwayo wobukhulu benqaku ngalinye kwi-matrix yamachaphaza, ukuhlalutya ubungakanani bamanqaku kwi-periphery ye-matrix yechaphaza, kunye nobukhulu be-matrix. amanqaku angaphakathi kwisangqa sematrix yamachaphaza ahlukile.Ngokuthelekisa kunokufumaneka kumlinganiselo, lo mlinganiso kukugqwesa lens.Ngalo mlinganiselo, kumlinganiselo wangempela unokwenziwa ukulungisa ukugqwesa

I-Ronghua, ngumenzi okhethekileyo kwi-R & D, ukwenza ngokwezifiso, ukuveliswa, ukuthengisa kunye nenkonzo yeemodyuli zekhamera, iimodyuli zekhamera ye-USB, iilensi kunye nezinye iimveliso.Ukuba unomdla wokuqhagamshelana nathi, nceda:
