Ezinhlelweni zokusebenzisa izithombe zezimboni, ukuhlanekezela kuyisitha esikhulu ekuqaphelweni kwesithombe kanye nokulinganiswa kobukhulu. Ngokusebenzisa umklamo wokukhanya onembile,amalensi okuphambuka okuphansiukunciphisa ukuhlanekezelwa kwesithombe sejometri—ngaleyo ndlela kuqinisekiswe ukunemba kokulinganisa kanye nokuthembeka kokuhlola—futhi ngenxa yalokho kube yingxenye ebalulekile emkhakheni wokuskena kwezimboni.
Amalensi aphansi angaphinda akhiqize ngokunembile i-geometry yento elinganiswayo, okwenza kube yinto ebalulekile ezimweni zezimboni ezidinga ukulinganiswa kobukhulu obuphezulu kanye nokuskena amabhakhodi. Nazi izimo eziyinhloko zokusetshenziswa kokuskena kwezimboni:
1.Ukulinganisa ubukhulu obunembile
Ukulinganisa ngokunemba izingxenye zezimboni ezifana nezingxenye ze-elekthronikhi kanye nezingxenye zemishini kuyindlela eyinhloko yokusetshenziswa kwezimboni kwamalensi aphansi okuphambuka. Lezi zimo zokukhiqiza ngokunemba zivame ukudinga ukuhlolwa okunembile kakhulu ezingeni le-sub-millimeter noma ngisho ne-micrometer. Ukuphambuka kungabangela kalula amaphutha okulinganisa ngokulinganisa, kuyilapho ukuthembeka okuphezulu kwamalensi aphansi okuphambuka kungaqinisekisa ukuthi imiphumela yokulinganisa iyiqiniso futhi ithembekile.
2.Ukuskena nokuqashelwa kwebhakhodi
Ukunemba kwesistimu yokubona komshini kuncike ngqo ekulawulweni kokuhlanekezelwa kwelensi yayo. Njengoba ama-barcode namakhodi e-QR esebenza njengezikhombisi ezibalulekile zokulandelelwa komkhiqizo, ukusetshenziswa kwama-lens okuhlanekezelwa okuphansi ngesikhathi sokuskena okusheshayo emigqeni yokuhlangana ezenzakalelayo kuvimbela ukwelulwa nokuguqulwa kwezinhlamvu ze-barcode, ngaleyo ndlela kuqinisekiswe ukuqashelwa okusheshayo nokunembile ngemishini yokuskena.
Lokhu kuwusizo ikakhulukazi ezimweni ezihilela ukuskenwa kweqoqo lama-micro-barcode aphezulu noma ama-barcode agcwele ibhokisi lonke ensimini ebanzi yokubuka; ezimweni ezinjalo, amalensi aphansi anciphisa ngempumelelo amazinga amaphutha okubona, okuqinisekisa ukuthembeka kokuhlelwa kwezinto kanye nezinhlelo zokulandelela umkhiqizo.
Amalensi aphansi avame ukusetshenziselwa ukulinganisa ubukhulu ngokunembile
3.Ukutholwa kwesici somphezulu
Amandla okuthwebula izithombe ngokunemba okuphezuluamalensi okuphambuka okuphansikwenza kube lula ukuthola amaphutha amancane; avame ukusetshenziswa ukuhlola izindawo zomkhiqizo ukuze kutholakale amaphutha afana nokuklwebheka, imifantu, ama-voids, amabhamuza, kanye nokungafani kobuntu. Izici zazo zokuhlanekezela okuphansi zivimbela ukuhlanekezela kokwakheka kwamaphutha, ngaleyo ndlela zigweme ukutholakala okungafanele noma ukwahlulela kabi.
Isibonelo, ekukhiqizweni nasekuhlolweni kwamaphaneli e-LCD, ingilazi ye-photovoltaic, kanye nengilazi yezimoto, amalensi abonisa ukuphambuka okuphansi angabamba ngokusobala amaphutha afana nokuklwebheka, amabhamuza, nezinto zangaphandle ebusweni bengilazi, kuyilapho kuqinisekiswa ukunemba kwejometri komugqa womphetho wengilazi.
4.Ukuma okunembe kakhulu kanye nokuhlonza
Ukuhlanekezelwa kwesithombe kubangela ukuthi izixhumanisi zesimo samaphuzu ezici ngaphakathi kwesithombe zishintshe, ngaleyo ndlela kuthinte ngqo ukunemba kokusebenza kwerobhothi kokubamba, ukubeka, noma ukuhlanganisa.
Njengengxenye yesiqondiso esibonakalayo ngaphakathi kwemigqa yokukhiqiza ezenzakalelayo, amalensi aphansi okuphambuka ahlinzeka ngedatha yesithombe enembile, okwenza amarobhothi akwazi ukubona nokuthola ngokunembile izingxenye zomsebenzi. Lesi siqondiso senza kube lula ukwenziwa kwemisebenzi—njengokuhlanganisa nokubamba—ngaleyo ndlela kufezwe ukulawula okuzenzakalelayo nokuthuthukisa ukusebenza kahle kokukhiqiza.
Amalensi aphansi okuphambuka asetshenziswa ekubekeni nasekukhombeni ngokunemba okuphezulu
5.Ukwenziwa kwedijithali kwepokuqoshiwemi-ateriyu kanyedimithombo ngesukukheniza
Amalensi aphansi okuphambukaZivame ukusetshenziswa ezimweni ezihilela ukuskena kwedijithali kwezinto eziphrintiwe, amadokhumenti, kanye nemidwebo yobuchwepheshe.
Isibonelo, ekubekweni kwamaphethini ezindwangu zezindwangu kanye nokuhlolwa kwekhwalithi yama-barcode ezintweni eziphrintiwe, amalensi aphansi okuphambuka angabuyisela ngokunembile isilinganiso nendawo yamaphethini, aqinisekise ukuthi usayizi wama-barcode aphrintiwe uhlangabezana nezindinganiso; ezimweni ezifana nokuphathwa kwamafayela ezimboni kanye nokwenza imidwebo yobunjiniyela ibe yedijithali, amalensi aphansi okuphambuka angabuyisela ngokunembile isilinganiso somugqa kanye nemininingwane yombhalo yemidwebo, agweme izinkinga ezifana nokwelula nokuguqulwa, aqinisekise ukuthi imibhalo ye-elekthronikhi eskeniwe iyahambisana nemidwebo yokuqala, futhi ahlangabezane nezidingo zokuhlela kwesibili kwe-CAD okulandelayo, ukugcinwa kwengobo yomlando kanye nokutholwa.
6.Ukuhlunga kwempahla kanye nokulinganisa amaphasela
Ukusetshenziswa kokuskena kwamalensi aphansi okuphambuka embonini yezokuthutha akufanele kuthathwe kancane. Ezikhungweni zokuhlunga zezokuthutha ezihlakaniphile, amalensi aphansi okuphambuka, ngokubambisana nezinzwa zokubona ze-3D noma amakhamera e-2D, angaskena ngokushesha ama-contour futhi alinganise umthamo wamaphakheji kumabhande okuhambisa, athole idatha ngokunembile njengobude, ububanzi, kanye nokuphakama kwamaphakheji okuhlela indlela yokuhlunga ngokuzenzakalela, ukubalwa kwempahla, kanye nokwenza ngcono indawo yokugcina impahla.
Amalensi aphansi aguquguqukayo nawo avame ukusetshenziswa embonini yezokuthutha
Ngaphezu kwalokho, ukuskena nokuhlola amalebula okupakisha, ubuqotho bokuvala, kanye nekhwalithi yokubukeka kokupakisha kwezimboni ezikhethekile njengokudla nemithi ukuqinisekisa ulwazi olunembile noluhambisanayo nakho kungenye yezindlela zokuskena zezimboni zamalensi aphansi okuphambuka.
Kusobala ukuthiamalensi okuphambuka okuphansi, ngezinzuzo zazo zokuphambuka okuphansi, ukwethembeka okuphezulu kwesithombe, kanye nokulinganisa okunembile, sezibe yingxenye ebalulekile yezinhlelo zokubona komshini futhi zisetshenziswa kabanzi ekuhlolweni okuzenzakalelayo kanye nokulawulwa kwekhwalithi ezimbonini ezifana nokukhiqiza izinto zikagesi, izimoto, ezokuthutha, kanye nokupakishwa komkhiqizo.
