Lub lens fisheye yog lub lens dav dav, tseem hu ua panoramic lens.Nws feem ntau suav hais tias lub lens nrog lub focal ntev ntawm 16mm lossis luv dua focal ntev yog lub lens fisheye, tab sis hauv engineering, lub lens nrog lub kaum sab xis saib ntau dua 140 degrees yog suav tias yog lub lens fisheye.Hauv kev xyaum, kuj tseem muaj cov lo ntsiab muag uas pom lub kaum ntse ntse tshaj lossis txawm tias ncav cuag 270 degrees.Lub lens fisheye yog ib pab pawg neeg tiv thaiv telephoto teeb nrog ntau lub thoob distortion.Lub lens pem hauv ntej ntawm lub lo ntsiab muag no yog parabolically protruding rau pem hauv ntej, thiab cov duab zoo ib yam li lub qhov muag ntawm ib tug ntses, li no lub npe "fisheye lens", thiab nws cov nyhuv pom tau zoo ib yam li cov ntses saib tej yam saum toj no dej.
Lub lens fisheye cia siab rau cov khoom siv qhia txog qhov loj ntawm lub thoob distortion kom tau txais lub kaum sab xis loj.Yog li ntawd, tshwj tsis yog rau cov khoom nyob hauv nruab nrab ntawm daim duab, lwm qhov chaw uas yuav tsum yog cov kab ncaj nraim muaj qee qhov distortions, uas ua rau muaj ntau yam kev txwv rau nws daim ntawv thov.Piv txwv li, hauv kev ruaj ntseg, lub lens fisheye tuaj yeem hloov ntau lub lens zoo tib yam los saib xyuas ntau yam.Txij li thaum saib lub kaum sab xis tuaj yeem ncav cuag 180º lossis ntau dua, yuav luag tsis muaj lub kaum sab xis rau kev saib xyuas.Txawm li cas los xij, vim yog qhov tsis sib xws ntawm cov duab, cov khoom yog qhov nyuaj rau kev lees paub los ntawm tib neeg lub qhov muag, uas txo cov peev xwm saib xyuas;Lwm qhov piv txwv yog nyob rau hauv lub teb ntawm robotics, automated robots yuav tsum tau mus sau cov duab cov ntaub ntawv ntawm ib puag ncig scenes thiab txheeb xyuas lawv coj coj ua.Yog tias siv lub lens fisheye, qhov kev sau tau zoo tuaj yeem nce 2-4 zaug, tab sis qhov aberration ua rau software nyuaj rau txheeb xyuas.Yog li yuav ua li cas peb thiaj paub cov duab los ntawm lub lens fisheye?Ib qho algorithm yog muab los txheeb xyuas cov haujlwm ntawm cov khoom hauv daim duab.Tab sis nws kuj yog ib qho nyuaj rau kev paub txog kev paub txog cov duab nyuaj vim qhov kev ua haujlwm nyuaj ntawm software.Yog li ntawd, txoj kev tam sim no yog tshem tawm cov distortion hauv daim duab los ntawm kev hloov pauv, thiaj li tau txais cov duab ib txwm muaj thiab tom qab ntawd txheeb xyuas nws.
Kev sib raug zoo ntawm cov duab voj voog thiab sensor yog raws li nram no:
Keeb kwm, cov lo ntsiab muag fisheye tsuas yog siv hauv kev yees duab vim tias lawv qhov kev zoo nkauj tshwj xeeb vim yog qhov txawv txav ntawm lub thoob lawv tsim thaum lub sijhawm ua duab.Nyob rau hauv xyoo tas los no, daim ntawv thov ntawm fisheye lens tau nquag siv nyob rau hauv lub tshav pob ntawm lub dav-angle duab, tub rog, soj ntsuam, panoramic simulation, spherical projection thiab thiaj li nyob.Piv nrog rau lwm cov lo ntsiab muag, lub lens fisheye muaj qhov zoo ntawm lub teeb yuag thiab me me.
