Umshini wokubuka umshiniIngabe ilensi eyenzelwe ukusetshenziswa ezinhlelweni zombono womshini, eyaziwa nangokuthi ama-lens wekhamera yezimboni. Izinhlelo zombono womshini zivame ukuhlanganisa amakhamera wezimboni, ama-lens, imithombo ekhanyayo, nesoftware yokucubungula isithombe.
Zisetshenziselwa ukuqoqa ngokuzenzakalela, zicubungule, futhi zihlaziye izithombe ukuze zigwebe ngokuzenzakalelayo ikhwalithi yemisebenzi yokusebenza noma ukukala okuphelele kwesikhundla ngaphandle kokuthintana. Zivame ukusetshenziselwa ukukalwa okunengqondo okuphezulu, umhlangano ozenzakalelayo, ukuhlolwa okungeyona eyonakalisayo, ukutholwa kwesici, ukuzulazula kwamarobhothi neminye imikhakha eminingi.
1.Yini okufanele ucabangele lapho ukhetha ama-lens wombono womshini?
Lapho ukhethaAmalensi wombono woMshini, udinga ukucubungula izinto ezahlukahlukene ukuthola ilensi evumelana kahle nawe. Izici ezilandelayo zinokucatshangelwa okuvamile:
Inkambu yokubuka (i-FOV) nebanga elisebenzayo (WD).
Inkambu yokubuka kanye nebanga elisebenzayo ukunquma ukuthi iyiphi into enkulu kangakanani ongayibona nebanga ukusuka kwilensi kuya entweni.
Uhlobo lwekhamera ehambisanayo nosayizi we-sensor.
Ilensi oyikhethayo kufanele ihambisane nesibonisi sakho sekhamera, kanye nesithombe se-lens kufanele sibe sikhulu noma silingane nebanga le-diagonal le-sensor.
Kudluliswa ugongolo lwezehlakalo.
Kuyadingeka ukucacisa ukuthi uhlelo lwakho lokusebenza ludinga ukuhlanekezela okuphansi, ukulungiswa okuphezulu, ukujula okukhulu noma ukucushwa kwe-lens enkulu ye-aperture.
Ubungako bento kanye namakhono wesinqumo.
Into enkulu kangakanani into ofuna ukuyithola nokuthi isixazululo sidingeka kanjani kudingeka sicace, esinquma ukuthi inkulumo enkulu kangakanani yokubuka nokuthi ikhamera engakanani oyidingayo.
Eizimo ze-nvelo.
Uma unezidingo ezikhethekile zemvelo, ezinjenge-Shockproof, Uthumeleli noma Ngamanzi, udinga ukukhetha ilensi engahlangabezana nalezi zidingo.
Isabelomali sezindleko.
Hlobo luni lwezindleko ongakwazi ukukhokha luzothinta uhlobo lwelensi nemodeli ogcine ukuyikhetha.
Ilensi yombono womshini
2.Indlela yokuhlukanisa ye-Machine Vision Lens
Kunezici eziningi okufanele zicatshangelwe lapho ukhetha amalensi.Amalensi wombono woMshinifuthi ingahlukaniswa ngezinhlobo ezahlukene ngokuya ngamazinga ahlukene:
Ngokusho kohlobo lobude obugxile, kungahlukaniswa ku:
I-Lens Egxile Engaguquki (ubude obugxile buhleliwe futhi abakwazi ukulungiswa), ukusondeza amalensi (ubude obugxile buguqukayo futhi ukusebenza kuyavumelana nezimo).
Ngokusho kohlobo lwe-aperture, kungahlukaniswa ku:
I-Lens ye-Manual Apertate (i-aperture idinga ukulungiswa ngesandla), i-lens ezenzakalelayo ye-lens (ilensi ingalungisa ngokuzenzakalelayo i-aperture ngokuya ngokukhanya okukhona).
Ngokusho kwezidingo zokucabanga, zingahlukaniswa:
Ama-lens ajwayelekile wokuxazulula (alungele izidingo ezijwayelekile zokuqapha kanye nokuhlolwa kwekhwalithi), ama-lens aphezulu (alungele ukutholwa okunembile, ukucabanga okunejubane kanye nezinye izinhlelo zokusebenza ezinezidingo eziphakeme).
Ngokusho kobukhulu bezinzwa, kungahlukaniswa ku:
Ama-lens amafomethi wezinzwa amancane (alungele izinzwa ezincane ezifana ne-1/4 ", 1/3", njll. , njll. Sensor), ama-lens amakhulu we-Sensor Formay (ngezinzwa ezigcwele noma ezigcwele noma ezinkulu).
Ngokusho kwemodi yokucabanga, ingahlukaniswa:
I-Monochrome Imaging Lens (ingabamba kuphela izithombe ezimnyama nezimhlophe), ilensi yokulinganisa imibala (ingathwebula izithombe zombala).
Ngokusho kwezidingo ezikhethekile ezisebenzayo, zingahlukaniswa ngokuthi:ama-lens aphansi wokuhlanekezela(Okunganciphisa umthelela wokuhlanekezela ngekhwalithi yesithombe futhi kufanelekile ukuthola izimo zohlelo lokusebenza ezidinga ukukalwa okunembile), amalensi alwa nama-anti-vibration (alungele izindawo zezimboni ezinama-vibrations amakhulu), njll.
