一,What yi-lens ukuhlanekezela esithombeni?
Ukuhlanekezela kwamalensi ezithombeni kubhekisa kokuhlaselwa okubonakalayo okwenzeka lapho ilensi yekhamera yehluleka ukukhiqiza kabusha isithombe sendaba esithathwe. Lokhu kuphumela emfanekisweni ohlanekezelwe olwelulwe noma ocindezelwe, kuya ngohlobo lokuhlanekezela. Kunezinhlobo ezimbili eziphambili zelensi yokuhlanekezela:Ukuhlanekezelanana-Ukuhlanekezela kwe-Pincushion.
Ukuhlanekezela umgqomo kwenzeka lapho imigqa eqondile eduzane nemiphetho yesithombe ibonakala i-curve ngaphandle, idale ukusebenza kwe-bulging. Ngokuhlanekezela ngePincursion, ngakolunye uhlangothi, kwenzeka lapho imigqa eqondile eduzane nemiphetho yesithombe ibonakala i-curve ngaphakathi, yakha umphumela onenqwaba.
Ukuphazanyiswa kwelensi kungenzeka ngenxa yezici ezahlukahlukene ezifana nokwakhiwa nokwakhiwa kwelensi, i-angle yokubuka, nebanga phakathi kwekhamera kanye nendaba. Izinga lokuhlanekezela lingahluka ngokuya ngelensi ethile esetshenziswayo kanye nezilungiselelo ezisetshenziswa ngumthwebuli wezithombe.
Ngenhlanhla, ukuhlanekekekekekezela kwamalensi kuvame ukulungiswa ngamasu ngemuva kokusebenza noma ngokusebenzisa isoftware ekhethekile eyenzelwe ukulungisa i-lens ukuphambuka. Kodwa-ke, kungcono njalo ukunciphisa ukuhlanekezela kwe-lens ngokusebenzisa ama-lens asezingeni eliphakeme futhi kufakwe ngokucophelela isibhamu sakho ukugwema ukuhlanekekezela ngokweqile.
二,Umehluko ekuhlanekezelweni phakathiaamalensi ama-spherical kanye namalensi ayindilinga.
Ama-lens asperical namalensi ayindilinga anezinhlobo zamalensi abonakalayo asetshenziswa kumakhamera, ama-telescopes, ama-microscopes, nakwamanye amathuluzi abonakalayo.
Amalensi ayindilingaIba nendawo egobile ebunjiwe njengengxenye ye-sphere, futhi uhlobo oluvame kakhulu lwelensi. Kodwa-ke, bangakwazi ukwethula ama-aferration aphezulu anjenge-afrrration eyindilinga, ama-coma, kanye nokuhlanekezela, ikakhulukazi uma kusetshenziswa ezindaweni ezinkulu noma ngamalensi amaningi e-angle.
Ama-lens asperical, ngakolunye uhlangothi, babe yindawo engeyona eye-spherical eyenzelwe ukulungisa lezi zingozi. Lokhu kuvumela izithombe ezibukhali ngokuhluka okungcono nokuncishiswa kokuhlanekezelwa, ikakhulukazi emaphethelweni ohlaka. Ama-lens asperical ajwayele ukusetshenziselwa amalensi aphelele, futhi angatholakala kuwo womabili ama-lens aphambili futhi asondeza.
Sekukonke, ukusetshenziswa kwamalensi a-asperical kungasiza ukuthuthukisa ukusebenza kwe-lens, ikakhulukazi ngokuya ngokunciphisa ukuhlanekezela nokunye ukuhlukunyezwa. Kodwa-ke, ama-lens asperical abiza kakhulu ukukhiqiza kunamalensi ayindilinga, angabenza babize kakhulu abathengi.
三,What yi-angle ebanzi yokuhlanekezela lens?
A I-engela enkulu yokuhlanekezela ukuhlanekezelaUhlobo lwelensi yekhamera evumela insimu ebanzi yokubuka kunelensi ejwayelekile ngenkathi inciphisa noma isusa ukuhlanekezela okungenzeka ngamalensi abanzi.
Ama-lens aude-angleIba nobude obugxile ekugxileni kunamalensi ajwayelekile futhi ingathwebula okuningi kwesigcawu ngohlaka olulodwa, kubenza badume ngokubona, izakhiwo, kanye nezithombe zangaphakathi. Kodwa-ke, ngenxa yombono obubanzi, bangakwazi futhi ukukhiqiza ukuhlanekezela, okungaholela emigqeni eqondile ebonakala egobile noma izinto ezibonakala zeluliwe noma ezihlanekezelwe.
Ama-lens aphansi abubanziyakhelwe ukunciphisa noma ukuqeda lokhu kuhlanekezelwa, okuvumela ukumelwa okunembile futhi okungokoqobo kwesigameko. Lawa ma-lens asetshenziswa kakhulu abathwebuli bezithombe abaqeqeshiwe abadinga insimu ebanzi yokubuka ngaphandle kokuyekethisa ikhwalithi yesithombe noma ukunemba.
四,WHat izicelo eziphambili ze-M12 Ukuhlanekezela Kwenyusa?
Le khasiI-M12 Lens ephansi yokuhlanekezelaIsetshenziswa kakhulu ku-Machine Vision kanye nezinhlelo ze-Computer Viseos, ikakhulukazi amakhamera nezinhlelo zezithombe ezidinga izithombe ezisezingeni eliphakeme ngokuhlanekezeka okuncane. Nazi ezinye izinhlelo zokusebenza eziphambili ze-M12 Low Wokuhlanekezela Lens:
I-automatio yezimboniN: Ama-lens aphansi wokuhlanekezela asetshenziswa ezinhlelweni ezenziwa ezimbonini zokubamba izithombe ezicacile nezinembile zezinto ezinqubweni zokukhiqiza.
Amarobhothi: Izicelo zeRobotic zivame ukusebenzisa ama-M12 aphansi wokuhlanekezela ama-lens ukuze izinqubo ezibonakalayo ezizwayo nezinhlelo zokuqondisa ezidinga ukunemba okuphezulu nokunemba.
Ukuphepha nokubhekwa: Ama-lens aphansi wokuhlanekezela asetshenziswa kakhulu kumakhamera ezokuphepha kanye nezinhlelo zokubhekwa zokubamba izithombe ezicacile nezinembile zabantu nezinto.
Ukucabanga kwezokwelapha: Ama-lens aphansi we-M12 aphansi asetshenziswa nezinhlelo zokucabanga zezokwelapha zokuxilonga nezinhloso zocwaningo.
Izimoto: I-M12 Lens ephansi yokuhlanekezela isetshenziswa ezinhlelweni zosizo lomshayeli athuthukile (ADAS) zezimoto, njengezinhlelo zokuvikeleka zomgwaqo kanye nezinhlelo zokugwema ukushayisana.
Sekukonke, i-M12 ephansi ye-Lens iyithuluzi eliguquguqukayo kunoma yiluphi uhlelo lokusebenza oludinga ukucabanga okuseqophelweni eliphezulu ngokuhlanekezeka okuncane.
