Qhov no yog ib qho teeb meem nyob rau hauv lub Scope ntawm optics, uas muaj nws tus kheej txheem txhais nyob rau hauv optics.Cov duab uas tsim los ntawm kev yees duab nrog lub koob yees duab yuav distorted.Piv txwv li, peb txhua tus muaj kev paub txog kev thaij duab nrog lub koob yees duab zoo tib yam hauv tsev.Muaj ib hom lens hu ua "wide-angle lens", uas yog hu ua "fisheye lens" ntau ruthlessly.Thaum koj thaij duab nrog lub lens zoo li no, koj yuav pom tias cov duab ntawm ob sab ntawm daim duab yog nkhaus.Qhov tshwm sim no tshwm sim los ntawm "lens distortion".Piv txwv ntawm "fisheye lens" yog vim "fisheye lens" yog ib lub lens nrog loj distortion.
Lub lens muaj distortion, qhov txawv yog tias qhov distortion txawv heev.Rau qhov kev tshuaj ntsuam xyuas qhov muag, nws yog qhov tseeb cia siab tias lub lens distortion siv tsawg npaum li qhov ua tau.Qhov no yog vim hais tias thaum lub zeem muag qhov system ua kom pom, nws tau ua rau ntawm cov duab thaij duab los ntawm lub koob yees duab.Yog hais tias lub koob yees duab lub koob yees duab yog "crooked", qhov tshwm sim ntawm qhov kev kuaj pom yuav tsis yog "tsim" - qhov no txhais tau hais tias lub beam sab sauv tsis raug thiab lub nqaj qis yog crooked.
Muaj ob txoj hauv kev rau lub zeem muag kom kho lub lens distortion: uas yog, pib ntawm lub hardware lossis pib ntawm software.Txoj kev pib los ntawm cov khoom siv yog yooj yim: tsuas yog siv lub lens nrog me ntsis distortion.Lub lens zoo li no hu ua telecentric imaging lens, uas yog kim, ntau dua 6 lossis 7 npaug ntawm tus nqi ntawm lub lens zoo tib yam.Qhov distortion ntawm hom lens no yog qis dua 1%, thiab qee qhov tuaj yeem ncav cuag 0.1%.Feem ntau cov kev ntsuas qhov muag pom kev siab tshaj plaws siv hom lens no: Txoj kev thib ob yog pib los ntawm software.Thaum ua "lub koob yees duab calibration", siv dot matrix ntawm tus qauv calibration module los xam.Txoj kev tshwj xeeb yog: tom qab ua tiav ntawm "lub koob yees duab calibration", qhov loj ntawm txhua lub ntsiab lus hauv dot matrix tau txais raws li kev ntsuas paub, thiab qhov luaj li cas ntawm cov dots ntawm qhov chaw ntawm lub dot matrix yog soj ntsuam.Lub ntsiab lus loj yog txawv.Ib qho piv tau tuaj yeem tau los ntawm kev sib piv, thiab qhov piv no yog qhov txawv ntawm lub lens.Nrog rau qhov piv txwv no, qhov txawv txav tuaj yeem kho tau thaum ntsuas qhov tseeb.
