Chii chinonzi lens distortion?

Iri idambudziko mumunda we optics, iyo ine yayo yakajairwa tsananguro mune optics.Mufananidzo wakagadzirwa nekutora mufananidzo nekamera uchakanganiswa.

Semuenzaniso, isu tese tine ruzivo rwekutora mifananidzo nemakamera akajairwa.Kune lens inonzi "wide-angle lens", inozivikanwawo se "fisheye lens", nemhando iyi yekutora mifananidzo, uchaona kuti mufananidzo uri kumativi mana emufananidzo wakakotama.Ichi chiitiko chinokonzerwa ne "lens distortion".Muenzaniso wekuti "fisheye lenzi" nekuti "fisheye lenzi" ihombe yekukanganisa lenzi.

Malenzi ane kukanganisa, mutsauko unongova kukanganisa kwakakura uye kudiki.Uye kune iyo yekuona yekuongorora system, hongu, ndiyo tariro yekuti lens kukanganisa idiki sezvinobvira.Izvi zvinodaro nekuti iyo yekuona sisitimu yekuona, iri pamufananidzo wemufananidzo wekamera.Kana iyo kamera yekufungidzira pane "yakatsveyama", saka maitiro ekuona system haazove "akakodzera".
Pane nzira mbiri dzeVision system yekugadziriswa kwekukanganiswa kwema lens.

(1) Kubva kune Hardware:

Iine diki diki yekukanganisa lens.Iyi lenzi inonzi telecenter imaging lens.Asi mutengo wayo unodhura se6 nguva kana kupfuura semutengo weakajairika lenzi.Mazhinji ehupamhi hwepamusoro hweiyo yekuona kuyerwa system, ine ma lens akadaro.

(2) Kubva pane software:

Mu "calibration yekamera", kushandiswa kwecalibration standard module pane dot matrix kuverenga.
Iyo chaiyo nzira ndeiyi: mushure mekupedzwa kwe "kamera calibration", zvichienderana nechiyero chinozivikanwa chehukuru hwechinhu chimwe nechimwe mu dot matrix, kuongorora saizi yemapoinzi ari kuperiphery yedoti matrix, uye saizi ye. mapoinzi ari mudenderedzwa remukati meiyo dot matrix akasiyana.Nekuenzanisa inogona kutorwa kubva pachiyero, ichi chiyero ndiko kukanganisa lens.Nechiyero ichi, muchiyero chaicho chinogona kuitwa kugadzirisa kukanganisa

Ronghua, inogadzira inyanzvi muR&D, kugadzirisa, kugadzira, kutengesa uye sevhisi yemamodule kamera, USB kamera modules, lenzi uye zvimwe zvigadzirwa.Kana uchida kutibata, ndapota:
