Umshini wokubuka umshiniyilensi yekhamera yezimboni eyenzelwe ngokukhethekile izinhlelo zombono womshini. Umsebenzi wayo oyinhloko ukuwusebenzisa isithombe sento ethathwe izithombe ku-sensor yekhamera yokuqoqwa kwesithombe okuzenzakalelayo, ukucubungula kanye nokuhlaziywa.
Isetshenziswa kabanzi emikhakheni eminingi efana nokukalwa okuphezulu, umhlangano ozenzakalelayo, ukuhlolwa okungelonakalisa okulimazayo, kanye nokuzulazula kwamarobhothi.
1,Umgomo welensi yombono womshini
Imigomo ye-Machine Vision Lens ikakhulukazi ifaka ukucabanga kwe-Optical, i-Geometric Optics, i-Optics ye-Global kanye nezinye izinkambu, kufaka phakathi ubude obugxile, inkambu yokubuka, i-aperture kanye namanye amapharamitha okusebenza. Okulandelayo, ake sifunde kabanzi ngemigomo ye-Machine Vision Lens.
Izimiso zokucabanga okubonakalayo.
Umgomo wokucabanga okubonakalayo ukuthi i-lens igxile ekukhanyiseni inzwa ngamaqembu amaningi we-lens (njengamalensi wesikhala namalensi wesikhala sento) ukukhiqiza isithombe sedijithali sento.
Isikhundla kanye nesikhala seqembu le-lens endleleni yokubona kuzothinta ubude obugxile, inkambu yokubuka, ukulungiswa kanye namanye amapharamitha okusebenza amalensi.
Izimiso ze-geometric optics.
Umgomo we-geometric optics we-lens ukugxila ekukhanyiseni okubonisiwe kusuka entweni ebusweni bezinzwa ngaphansi kwezimo zokubonisa ukukhanya kanye ne-rection agculisekile.
Kule nqubo, kuyadingeka ukunqoba ukuguquguquka, ukuhlanekezela, ukuguquguquka kwe-chromatic nezinye izinkinga zelensi ukuthuthukisa ikhwalithi yokucabanga.
Izimiso ze-Work Optics.
Lapho uhlaziya i-lens imaging usebenzisa imigomo ye-optics yomzimba, kuyadingeka ukubheka imvelo yegagasi kanye nokuphazanyiswa kokukhanya. Lokhu kuzothinta amapharamitha okusebenza amalensi afana nesixazululo, umehluko, ukusakazeka, ukuhlakazeka, njll. Isibonelo, ukumboza amalensi kungabhekana nezinkinga nokuthuthukisa ikhwalithi yesithombe.
Ilensi yombono womshini
Ubude obugxile kanye nomkhakha wokubuka.
Ubude obugxile belensi bubhekisela ebangeni phakathi kwento kanye nelensi. Inquma usayizi wenkambu yelensi yokubuka, okungukuthi, uhla lwezithombe lapho ikhamera ingathwebula khona.
Isikhathi eside ubude obugxile, abathi mancane emkhakheni wokubukwa, kanye nokukhuliswa kwesithombe; Okufushane ubude obugxile, ababanzi emkhakheni wokubuka, futhi okuncane kokukhuliswa kwesithombe.
I-aperture nokujula kwenkambu.
I-aperture ingumgodi oguqukayo elensi elawula inani lokukhanya elidlula ku-lens. Usayizi we-apertate ungaguqula ukujula kwenkambu (okungukuthi, uhla olucacile lokucabanga), oluthinta ukukhanya kwesithombe nekhwalithi ye-imaging.
Lapho likhulisa ukuthambekela, ukukhanya okwengeziwe kungena nokujula kwensimu; Uma kuncane i-aperture, ukukhanya okuncane kungena kanye nokujula kwensimu.
Isinqumo.
Isixazululo sibhekisela ebangeni elincane lens elingasixazulula, futhi lisetshenziselwa ukukala ukucaciswa kwesithombe selensi. Ukuphakama kwesinqumo, kungcono ikhwalithi yesithombe yelensi.
Ngokuvamile, lapho kuqhathaniswa, ukulungiswa kweumshini wokubuka umshiniKufanele kuhambisane namaphikseli enzwa, ukuze ukusebenza kohlelo lwelensi kungasetshenziswa ngokugcwele.
2,Umsebenzi welensi yombono womshini
Izinhlelo zombono womshini zisetshenziswa kabanzi ekukhiqizweni kwe-elekthroniki, ezokukhiqiza izimboni kanye nezinye izinkambu. Njengengxenye ebaluleke kakhulu yohlelo lombono, ama-Mensesion Vision Lens anomthelela onqumayo ekusebenzeni nasemisebenzini yohlelo.
Imisebenzi esemqoka yama-lens wombono womshini imi ngalendlela elandelayo:
Form isithombe.
Uhlelo lokubona luqoqa imininingwane mayelana nento ekhonjiwe ngokusebenzisa i-lens, futhi i-lens igxile ekukhanyeni okuqoqwe kwinzwa yekhamera ukuze wakhe isithombe esicacile.
Imisebenzi ye-Machine Vision Lens
Ihlinzeka ngomkhakha wokubuka.
Inkambu yokubukwa kwama-lens inquma usayizi nensimu yokubuka kwento eqondiwe yikhamera yekhamera ezoyiqoqa. Ukukhethwa kwensimu yokubuka kuncike ebudweni obugxile belensi kanye nosayizi wezinzwa wekhamera.
Lawula ukukhanya.
Amalensi amaningi wokubona umshini anokulungiswa kwe-aperture elawula inani lokukhanya okufaka ikhamera. Lo msebenzi ubalulekile ekutholeni izithombe ezisezingeni eliphakeme ngaphansi kwezimo ezihlukile zokukhanyisa.
Nquma isixazululo.
Ilensi enhle inganikeza izithombe ezicacile, ezisezingeni eliphakeme ngemininingwane ephezulu, okubaluleke kakhulu ekutholweni okunembile nokukhonjwa kwezinto.
Ukulungiswa kokuhlanekezela kwe-lens.
Lapho ukuklama ama-Mensesion ama-Menses lens, ukuhlanekezela kuzolungiswa ukuze ilensi ithole imiphumela eyiqiniso futhi enembile ngesikhathi sokucutshungulwa kwezithombe.
Ukucabanga okujulile.
Amanye ama-lens athuthukile anganikeza imininingwane ejulile, ebaluleke kakhulu emisebenzini efana nokutholwa kwento, ukuqashelwa, kanye nokubekwa esikhundleni.
Imicabango yokugcina:
UChuangan wenze ukwakheka kokuqala nokukhiqizwa kweAmalensi wombono woMshini, ezisetshenziswa kuzo zonke izici zezinhlelo zombono womshini. Uma unentshisekelo noma unezidingo zamalensi wombono womshini, sicela uxhumane nathi ngokushesha okukhulu.
