Emkhakheni we-automation yezimboni, amakhamera namalensi kuyizinto ezibalulekile zokuhlola nokuhlonza ngokubona. Njengedivayisi engaphambili yekhamera, ilensi inomthelela obalulekile kwikhwalithi yesithombe sokugcina sekhamera.
Izinhlobo ezahlukene zelensi kanye nezilungiselelo zamapharamitha zizoba nomthelela oqondile ekucaceni kwesithombe, ukujula kwensimu, isixazululo, njll. Ngakho-ke, ukukhetha ilensi efanelekile kumakhamera ezimboni kuyisisekelo sokufeza ukuhlolwa okubonakalayo kwekhwalithi ephezulu.
1.Ukuhlukaniswa kwamalensi ekhamera yezimboni
Ochwephesheamalensi ekhamera yezimboniingahlukaniswa ngezigaba ezilandelayo:
(1)Ilensi yokugxila egxilile
Ilensi yokugxila egxilile uhlobo lwelensi olusetshenziswa kakhulu kumakhamera ezimboni. Inobude obuqondile obubodwa kanye nobubanzi bokudubula obugxilile. Ifanelekela ukunquma ibanga kanye nosayizi wethagethi yokuthola. Ngokulungisa ibanga lokudubula, osayizi abahlukene bebanga lokudubula bangafinyelelwa.
(2)Ilensi ye-Telecentric
Ilensi ye-Telecentric uhlobo olukhethekile lwelensi yekhamera yezimboni enomzila omude wokukhanya, ongafinyelela ukujula okukhulu kwensimu kanye nomphumela wokudubula ocacile. Lolu hlobo lwelensi lusetshenziswa kakhulu ezinhlelweni zokuhlola okubonakalayo ezinembile nezizinzile, njengombono womshini, ukulinganisa okunembile kanye nezinye izinkambu.

(3)Ilensi yokuskena umugqa
Ilensi yokuskena ngomugqa iyilensi yokuskena ngesivinini esikhulu esetshenziselwa amakhamera okuskena ngomugqa noma amakhamera e-CMOS. Ingafinyelela ukuskena kwesithombe ngesivinini esikhulu nangokunembile futhi ifanele ukuhlolwa kwekhwalithi nokuhlonza imigqa yokukhiqiza ngesivinini esikhulu.
(4)Ilensi ye-Varifocal
Ilensi ye-varifocal ilensi engashintsha ukukhulisa. Ingazivumelanisa nezidingo ezahlukene zokuhlola ngokulungisa ukukhulisa. Ifanele ukuhlolwa kwezingxenye ngokunemba, ucwaningo lwesayensi kanye nezinye izimo.
Ngokukhetha uhlobo lwelensi kanye nezilungiselelo zepharamitha ezifanele ikhamera, ungathola imiphumela yesithombe sekhwalithi ephezulu kanye nemiphumela yokuhlolwa okunembile kokubona. Ngesikhathi esifanayo, usebenzisa ikhwalithi ephezulu kanye nokuzinza okuphezulu.amalensi ekhamera yezimbonikungathuthukisa nokusebenza kahle kokukhiqiza futhi kunciphise izindleko zokulungisa.
Ngakho-ke, kulabo ababandakanyeka ekuboneni komshini nasekucubunguleni izithombe, kubaluleke kakhulu ukuqonda nokuqonda izinhlobo, izimiso zokukhetha kanye nezindlela zokusebenzisa amalensi ekhamera yezimboni.
2.Izimiso zokukhetha amalensi ekhamera yezimboni
(1)Ukunquma ukuthi ukhethe ukugxila okugxilile nomavilensi ye-arifocal
Amalensi agxilile anezinzuzo zokuphambuka okuncane kanye nokusebenza okubiza kakhulu, futhi asetshenziswa kabanzi ezinhlelweni zokuhlola okubonakalayo. Kodwa-ke, kwezinye izimo lapho insimu yokubuka idinga ukushintshwa, amalensi okusondeza ayinketho.
Ngesikhathi senqubo yokuthwebula izithombeumbono womshiniUma kwenzeka, kubalulekile ukunquma ukuthi ukukhuliswa kuyadingeka yini. Uma kunjalo, kufanele kusetshenziswe ilensi ye-varifocal. Ngaphandle kwalokho, ilensi egxilile ingahlangabezana nezidingo.

(2)Nquma ibanga lokusebenza kanye nobude bokugxila
Ibanga lokusebenza kanye nobude obuqondile ngokuvamile kubhekwa ndawonye. Ngokuvamile, isinqumo sesistimu sinqunywa kuqala, bese ukukhuliswa kutholakala ngokuhlanganisa usayizi wephikseli wekhamera yezimboni.
Ibanga elingaba khona lesithombe esiqondiwe laziwa ngokuhlanganisa imikhawulo yesakhiwo sendawo, kanti ubude obuqondile kanye nobude belensi yekhamera yezimboni kuyalinganiswa ngokwengeziwe. Ngakho-ke, ubude obuqondile belensi yekhamera yezimboni buhlobene nebanga lokusebenza kanye nesisombululo sekhamera yezimboni.
(3)Izidingo zekhwalithi yesithombe
Ezinhlelweni zokubona komshini, amakhasimende ahlukene adinga ukunemba okuhlukile kokuthola, futhi ikhwalithi yesithombe ehambisanayo nayo ingase ihluke. Lapho ukhetha ilensi yekhamera yezimboni, usayizi wesithombe udinga ukufana nosayizi wobuso obuzwela ukukhanya kwekhamera yezimboni, ngaphandle kwalokho ikhwalithi yesithombe yensimu yokubuka esemaphethelweni ayinakuqinisekiswa.
Ezinhlelweni zokulinganisa umbono womshini, ikhwalithi yesithombe ihlobene nesisombululo, izinga lokuphambuka kanye nokuphambuka kwelensi yezimboni.
(4)Imbobo kanye nesixhumi esibonakalayo
Ukuvulwa kweamalensi ekhamera yezimboniKuthinta kakhulu ukukhanya kwendawo yokuthwebula izithombe, kodwa embonweni wamanje womshini, ukukhanya kokugcina kwesithombe kunqunywa yizici eziningi ezifana nokuvuleka, izinhlayiya zekhamera, isikhathi sokuhlanganiswa, umthombo wokukhanya, njll. Ngakho-ke, ukuze kutholakale ukukhanya kwesithombe okufiswayo, kudingeka izinyathelo eziningi zokulungisa.
Isixhumi selensi sekhamera yezimboni sibhekisela esixhumi esibonakalayo sokufaka phakathi kwekhamera nelensi yekhamera. Okubili kumele kufane. Uma kungenakufana, ukuguqulwa kufanele kucatshangelwe.
Ukukhethwa kwamalensi ezimboni
(5)Ingabe kudingeka ilensi ye-telecentric?
Uma wahlulela ukuthi into ehlolwayo iwugqinsi, ukuthi ngabe kudingeka kuhlolwe izindiza eziningi, ukuthi into inomgodi, ukuthi into ingumkhiqizo onezinhlangothi ezintathu, ukuthi into ikude kangakanani nelensi, njll., ukusebenzisa amalensi ekhamera yezimboni ajwayelekile kulezi zimo kuzokhiqiza i-parallax, okuholela emiphumeleni yokuhlola enganembile.
Ngalesi sikhathi, ukusetshenziswa kwamalensi ezimboni asebenzisa i-telecentric kungaxazulula ngempumelelo lezi zinkinga. Ngaphezu kwalokho, amalensi asebenzisa i-telecentric anokuhlanekezela okuphansi kanye nokujula okukhulu kwensimu, futhi ngesikhathi esifanayo, anokunemba okuphezulu kokuhlola kanye nokunemba okungcono.
Imicabango Yokugcina:
UChuangAn wenze umklamo wokuqala kanye nokukhiqizwa kweamalensi ezimboni, ezisetshenziswa kuzo zonke izici zezicelo zezimboni. Uma unesithakazelo noma unesidingo samalensi ezimboni, sicela usithinte ngokushesha okukhulu.
