Qhov no yog ib qho teeb meem nyob rau hauv lub teb ntawm optics, uas muaj nws tus kheej txheem txhais nyob rau hauv optics.Cov duab tsim los ntawm kev thaij duab nrog lub koob yees duab yuav raug distorted.
Ua piv txwv, peb txhua tus muaj kev paub txog kev thaij duab nrog lub koob yees duab zoo tib yam.Muaj lub lens hu ua "wide-angle lens", tseem hu ua "fisheye lens", nrog rau hom lens no los thaij duab, koj yuav pom tias cov duab ntawm plaub sab ntawm daim duab yog khoov.Qhov tshwm sim no tshwm sim los ntawm "lens distortion".Piv txwv hais tias "fisheye lens" vim hais tias "fisheye lens" yog lub lens loj distortion.
Lenses muaj distortion, qhov txawv tsuas yog distortion yog loj thiab me.Thiab rau qhov kev tshuaj ntsuam xyuas qhov muag, tau kawg, yog qhov kev cia siab tias lub lens distortion yog me me li sai tau.Qhov no yog vim lub zeem muag qhov system rau kev kuaj pom, nyob ntawm cov duab ntawm lub koob yees duab duab.Yog hais tias lub koob yees duab duab ntawm "crooked", tom qab ntawd qhov kev tshawb pom qhov system yuav tsis yog "tsim nyog".
Muaj ob txoj hauv kev rau Kev Pom Zoo rau kev kho lub lens distortion.
(1) Los ntawm hardware:
Nrog ib tug me me distortion lens.Lub lens no hu ua telecenter imaging lens.Tab sis nws tus nqi yog kim li 6 npaug los yog ntau dua li tus nqi ntawm cov lo ntsiab muag zoo tib yam.. Qhov aberrations ntawm cov lo ntsiab muag yog qis dua 1%, thiab qee qhov tuaj yeem ncav cuag 0.1%.Feem ntau ntawm qhov raug siab dua ntawm qhov kev ntsuas qhov muag, nrog rau cov lo ntsiab muag zoo li no.
(2) Los ntawm software:
Nyob rau hauv "lub koob yees duab calibration", kev siv calibration standard module ntawm dot matrix los xam.
Cov txheej txheem tshwj xeeb yog: tom qab ua tiav ntawm "lub koob yees duab calibration", raws li kev ntsuas qhov loj ntawm txhua qhov taw qhia hauv dot matrix, txhawm rau txheeb xyuas qhov loj ntawm cov ntsiab lus nyob rau hauv qhov chaw ntawm lub dot matrix, thiab qhov loj ntawm cov ntsiab lus nyob rau hauv lub puab voj voog ntawm dot matrix yog txawv.Los ntawm kev sib piv tuaj yeem muab tau los ntawm qhov piv, qhov piv no yog lub lens distortion.Nrog rau qhov piv txwv no, hauv kev ntsuas qhov tseeb tuaj yeem ua kom kho qhov tsis sib xws
Ronghua, yog cov chaw tsim khoom tshwj xeeb hauv R & D, customization, ntau lawm, muag thiab kev pabcuam ntawm lub koob yees duab modules, USB lub koob yees duab modules, lo ntsiab muag thiab lwm yam khoom.Yog xav tiv tauj peb, thov:
