Iko kuyerwa kwechiyero chemuchina wekuyeresa chiratidzo kuchakanganiswa nemamiriro matatu, ayo ari optical kukanganisa, mechanical kukanganisa uye kukanganisa kwekushanda kwevanhu.
Iko kukanganisa kwemuchina kunonyanya kuitika mukugadzira uye kuunganidza maitiro emuchina wekuyeresa chiratidzo.Tinogona kunyatso kudzikisa chikanganiso ichi nekuvandudza kunaka kwegungano panguva yekugadzira.
Aya anotevera matanho ekudzivirira kudzivirira kukanganisa kwemuchina:
1. Pakuisa njanji yekutungamira, hwaro hwayo hunofanirwa kunge hwakakwana mwero, uye chiratidzo chedhiza chinoda kushandiswa kugadzirisa kurongeka kwayo.
2. Kana uchiisa X uye Y axis grating vatongi, ivo vanofanirawo kuchengetwa munzvimbo yakakwana yakatwasuka.
3. The worktable inofanira kugadziridzwa kuti nhanho uye verticality, asi ichi ndicho bvunzo kukwanisa kwenyanzvi pagungano.
Optical kukanganisa ndiko kukanganisa uye kukanganisa kunogadzirwa pakati penzira yemaziso uye zvikamu panguva yekufungidzira, iyo inonyanya kuenderana nekugadzirwa kwekamera.Semuenzaniso, apo chiedza chechiitiko chinopfuura nepakati pe lens imwe neimwe, kukanganisa kwekugadzirisa uye kukanganisa kweCCD lattice position inogadzirwa, saka optical system ine nonlinear geometric distortion, zvichiita kuti pave nemhando dzakasiyana-siyana dzegeometric kukanganisa pakati pechinangwa chemufananidzo uye theoretical. image point.
Iyi inotevera sumo pfupi yekukanganisa kwakawanda:
1. Radial distortion: Inonyanya kunetsa ye symmetry yeiyo main optical axis yekamera lens, ndiko kuti, kukanganisa kweCCD uye chimiro che lens.
2. Eccentric distortion: Chikonzero chikuru ndechokuti optical axis centers ye lens imwe neimwe haigoni kuva yakasimba collinear, zvichiita kuti zvisakanganise optical centers uye geometric centers ye optical system.
3. Thin prism distortion: Izvo zvakaenzana nekuwedzera prism yakaonda kune optical system, iyo isingazokonzeri kutsauka kweradial, asiwo tangential kutsauka.Izvi zvinokonzerwa nekugadzira lens, kukanganisa kwekugadzira, uye zvikanganiso zvekuisa machining.
Yekupedzisira kukanganisa kwevanhu, iyo inowirirana zvakanyanya nemaitiro emushandisi ekushanda uye inonyanya kuitika pamakina emaoko uye semi-otomatiki michina.
Kukanganisa kwevanhu kunonyanya kusanganisira zvinotevera:
1. Tora kukanganisa kwechiyero chekuyera (unsharp uye burr edges)
2. Iko kukanganisa kweZ-axis yakatarisa kureba kugadzirisa (kukanganisa kweiyo yakajeka yekutarisa point kutonga)
Pamusoro pezvo, iko kurongeka kwemuchina wekuyeresa wechiratidzo kunoenderana zvakare nekuwanda kwayo kwekushandisa, kugara uchigadzirisa uye kushandiswa kwenzvimbo.Zviridzwa zvemazvo zvinoda kugadziriswa nguva dzose, chengeta muchina wakaoma uye wakachena kana usiri kushandiswa, uye chengeta kure nenzvimbo dzine vibrate kana ruzha rukuru paunenge uchiushandisa.
