Iri idambudziko mukati mechikamu che optics, iyo ine yayo yakajairika tsananguro mune optics.Mufananidzo unogadzirwa nekutora mufananidzo nekamera uchakanganiswa.Semuenzaniso, isu tese tine ruzivo rwekutora mifananidzo nemakamera akajairwa kumba.Kune rudzi rwe lens inonzi "wide-angle lens", iyo inonzi "fisheye lens" zvakanyanya hutsinye.Paunotora foto nerudzi urwu rwelenzi, uchaona kuti mufananidzo uri pamativi emufananidzo wakakombama.Ichi chiitiko chinokonzerwa ne "lens distortion".Muenzaniso we "fisheye lens" imhaka yekuti "fisheye lens" irenzi ine kukanganisa kukuru.
Iyo lens ine kukanganisa, mutsauko ndewekuti kukanganisa kunosiyana zvakanyanya.Kune yekuona yekutarisa sisitimu, zvinotarisirwa kuti kukanganiswa kwe lens kunoshandiswa idiki sezvinobvira.Izvi zvinodaro nekuti kana iyo yekuona sisitimu ichiita yekuona, inoitwa pamufananidzo unofananidzwa nekamera.Kana kufungidzira kwekamera "kwakatsveyama", mhedzisiro yekuonekwa kwehurongwa haizove "chaiyo" - izvi zvinoreva kuti danda repamusoro harina kunaka uye danda rezasi rakakombama.
Pane nzira mbiri dzekuti sisitimu yechiratidzo igadzirise kukanganisa lens: ndiko kuti, kutanga kubva kune Hardware kana kutanga kubva kusoftware.Nzira yekutanga kubva kune hardware iri nyore: ingoshandisa lens ine zvishoma kukanganisa.Rudzi urwu rwelenzi runodaidzwa kuti telecentric imaging lens, inodhura, inodarika katanhatu kana kanomwe mutengo weakajairika.Kukanganiswa kwemhando iyi yelens iri pasi pe1%, uye vamwe vanogona kusvika 0.1%.Mazhinji epamusoro-chaiyo yekuyera masystem anoshandisa iyi mhando yelenzi: Yechipiri nzira ndeyekutanga kubva pasoftware.Paunenge uchiita "calibration yekamera", shandisa dot matrix pane calibration standard module kuverenga.Iyo chaiyo nzira ndeiyi: mushure mekupedzwa kwe "kamera calibration", saizi yeimwe neimwe poindi mu dot matrix inowanwa zvichienderana nechiyero chinozivikanwa, uye saizi yemadoti padivi peiyo dot matrix analysed.Saizi yepoindi yakasiyana.Chiyero chinogona kuwanikwa nekuenzanisa, uye chiyero ichi ndiko kukanganisa kwe lens.Nechiyero ichi, kukanganisa kunogona kugadziriswa panguva yekuyera chaiko.
