Kwadalwa ngo 01.22
Emhlabeni osheshayo wocwaningo lwesayensi kanye nokuxilongwa kwezempilo, ukuzenzakalela kwelabhorethri sekuyisisekelo sokusebenza kahle, ukunemba, nokukala. Phakathi kobuchwepheshe obuqhuba le ngunguquko, umbono wekhamera ugqama—hhayi njengengxenye esekelisayo nje, kodwa njengesisekelo esibalulekile esivumela ukwenza izinqumo ngesikhathi sangempela, kunciphisa amaphutha omuntu, futhi kuvule amathuba amasha ekuhlolweni okuphezulu. Namuhla, sihlola ukuthi kanjaniumbono wekhameraubuyisa kanjani izinhlelo zokuzenzakalela kwelabhorethri, izicelo zawo ezibalulekile kuzo zonke izimboni, izimpumelelo zobuchwepheshe ezikhuthaza ukukhula kwawo, nokuthi kungani kuyinto eshintsha imidlalo emalabhorethri ahlose ukuhlala phambili enkathini yemithi enembayo nocwaningo oluthuthukile.
Iminyaka eminingi, ukuzenzakalela ezindlini zokuhlola bekuncike kakhulu ezinhlelweni zemishini kanye nezinzwa eziyisisekelo ukuze kwenziwe lula imisebenzi ephindaphindwayo—kusukela ekufakeni amaphayiphu nasekuphathweni kwezibonelo kuze kube ukulungiswa kwezivivinyo. Kodwa-ke, lezi zinhlelo zazingenamandla okubona nokuzivumelanisa nezinguquko ezibonelweni, ukuguga kwemishini, noma izinto ezingalindelekile. Lesi sikhala sivame ukubangela amaphutha abiza kakhulu, ukungathembeki kwedatha, nokulinganiselwa ekukaleni. Nansi ubuchwepheshe bokubona ngekhamera: ngokuhlanganisa izithombe ezinokulungiswa okuphezulu, izindlela ezithuthukisiwe zokucubungula izithombe, kanye nobuchwepheshe bokufakelwa (AI), izinhlelo zesimanje zokuzenzakalela ezindlini zokuhlola manje seziyakwazi ukuqonda imvelo yazo ngokucacile okungakaze kube khona ngaphambili, ukwenza ukulungiswa okusheshayo, nokukhiqiza imininingwane ewusizo kusuka kudatha ebonakalayo. Leli shintsho kusuka "ekuzenzakaleleni okungaboni" kuya "ekuzenzakaleleni okuhlakaniphile okuqondiswa ngemibono" luyaluguqula indlela izindlu zokuhlola ezisebenza ngayo, luguqula izinqubo ezenziwa ngesandla, ezinamaphutha, zibe izindlela zokusebenza ezingathembekile kakhulu, eziqhutshwa yidatha.
Ukuvela Kombono weKhamera Ekuzenzakaleleni Kwelabhorethri: Kusukela Ekubonisweni Okuyisisekelo kuya Ekuhlakanipheni Okunikezwe yi-AI
The journey of camera vision in laboratory settings began with simple image capture for documentation purposes—for example, capturing images of gel electrophoresis results or cell cultures for later analysis. Early systems were low-resolution, slow, and required manual interpretation, offering little to no value in real-time process control. Over the past decade, however, three key technological advancements have propelled camera vision into the core of automation:
Okokuqala, ukwanda kwamakhamera aphezulu, ancane. Amakhamera esimanje asezingeni eliphezulu ahlanganisa isinqumo esiphezulu (kufika ku-4K nangaphezulu), amazinga okudubula asheshayo, nokuzwela ezinhlobonhlobo zamagagasi—kusukela ekukhanyeni okubonakalayo kuya ku-ultraviolet (UV) kanye ne-infrared (IR). Lokhu kubavumela ukuthi bathwebule izithombe ezinemininingwane zezincane kakhulu (isib. amangqamuzana ayedwa, amaconsana amancane) futhi bathole izinguquko ezicashile ezingabonakali emehlweni omuntu. Ngaphezu kwalokho, isimo sawo esincane sivumela ukuhlanganiswa okungenamihawu ezindaweni ezincane zelabhorethri, njengaphakathi kwezinhlelo zokubamba uketshezi ezizenzakalelayo noma iz incubator.
Okwesibili, ukuthuthukiswa kwezindlela eziphambili zokucubungula izithombe. Ukuhlaziywa kwezithombe kwakudala kwakusekelwe ekubekeni imingcele eyisisekelo nasekuqaphelweni kwemiphetho, okwakunzima ezindaweni ezihlukahlukene zaselebhu (isibonelo, ukukhanya okungalingani, amasampula ahlangene, iziqukathi ezicacile). Izindlela zanamuhla zisebenzisa ubuchwepheshe njengokufunda ngomshini (ML), ukufunda okujulile (DL), kanye nombono wekhompyutha ukuhlukanisa izithombe, ukukhomba izinto, ukukala izici (isibonelo, usayizi, isimo, umbala), nokuhlukanisa amasampula ngokunemba okuphezulu. Ngokwesibonelo, amanethiwekhi ezinzwa ezihlangene (CNNs) angakwazi ukuhlukanisa phakathi kwezeli eziphilile nezinephutha kusampula legazi, noma ukukhomba izitsha ezingcolile ngesikhathi sangempela.
Okwesithathu, ukuhlanganiswa kwe-AI (Artificial Intelligence) kanye ne-machine learning kulawulo olubikezelayo noluvumelanayo. Ngokungafani nokucubungula izithombe ezingashintshi, izinhlelo zekhamera ezisekelwa yi-AI zingafunda kusuka kudatha yomlando, zivumelanise nezimo ezintsha, futhi zenze izinqumo ezibikezelayo. Ngokwesibonelo, uhlelo lokuzenzakalela oluqondiswa ngombono lungafunda ukulungisa ivolumu yokufaka amachashaza ngokuya ngobukhulu besampula (esitholwe ngokuhlaziya izithombe zokwakheka kwamaconsa) noma libike ukwehluleka kwemishini ngokuqapha izinguquko ezicashile ezingxenyeni zomshini (isibonelo, ukuguga kwethiphu ye-pipette) ngokuthwebula izithombe njalo.
Key Applications: Where Camera Vision Adds the Most Value in Lab Automation
Umthelela wokubona ngekhamera uzwakala ezinhlelweni eziningi zokusebenza emalabhorethri, kusukela ekuhloleni kwezokwelapha nasekutholeni imithi kuya kwesayensi yezinto nasekuhloleni kwemvelo. Nansi eminye yemisebenzi ebaluleke kakhulu lapho ukuzenzakalela okuhamba phambili kuhlinzeka ngezinsiza ezibonakalayo:
