Ukuchaneka kokulinganisa komatshini wokulinganisa umbono kuya kuchaphazeleka ziimeko ezintathu, ezizezi: impazamo yokujonga, impazamo yoomatshini kunye nempazamo yokusebenza komntu.
Impazamo yoomatshini ikakhulu yenzeka kwinkqubo yokuvelisa nokuhlanganisa umatshini wokulinganisa umbono. Singayinciphisa ngempumelelo le mpazamo ngokuphucula umgangatho wokuhlanganisa ngexesha lokuvelisa.
Nazi iindlela zokuthintela iimpazamo zoomatshini:
1. Xa ufaka ireyile yesikhokelo, isiseko sayo kufuneka sibe kumgangatho owaneleyo, kwaye kufuneka kusetyenziswe isalathisi sokudayela ukulungisa ukuchaneka kwenqanaba layo.
2. Xa ufaka iirula zegrating ze-X kunye ne-Y axis, kufuneka zigcinwe zikwimeko ethe tye ngokupheleleyo.
3. Itheyibhile yokusebenza kufuneka ilungiswe ngokwenqanaba kunye nobude bayo, kodwa olu luvavanyo lwesakhono somchwephesha sokudibanisa.
Impazamo yokujonga kukuphazamiseka kunye nokuphazamiseka okwenziwa phakathi kwendlela yokujonga kunye nezinto ngexesha lokufota, oku kunxulumene kakhulu nenkqubo yokwenziwa kwekhamera. Umzekelo, xa ukukhanya kwesiganeko kudlula kwilensi nganye, impazamo yokurhawuzelelwa kunye nempazamo yendawo yelattice yeCCD ziyaveliswa, ngoko ke inkqubo yokujonga ine-geometric engalunganga, nto leyo ebangela iintlobo ezahlukeneyo zokuphazamiseka kwe-geometric phakathi kwendawo yomfanekiso ekujoliswe kuyo kunye nendawo yomfanekiso yethiyori.
Oku kulandelayo yintshayelelo emfutshane yezinto ezininzi ezigqwethekileyo:
1. Ukuphazamiseka kwemitha: Ngokuyintloko yingxaki yokulingana kwe-axis ephambili ye-optical yelensi yekhamera, oko kukuthi, iziphene zeCCD kunye nokuma kwelensi.
2. Ukuphazamiseka kwe-Eccentric: Isizathu esiphambili kukuba iziko le-optical axis lelensi nganye azinakuba yi-collinear ngokungqongqo, nto leyo ebangela ukuba iziko le-optical lingahambelani kunye neziko zejometri zenkqubo ye-optical.
3. Ukuphazamiseka kweprism encinci: Kufana nokongeza iprism encinci kwinkqubo ye-optical, engayi kubangela kuphela ukuphambuka kwe-radial, kodwa kunye nokuphambuka kwe-tangential. Oku kungenxa yoyilo lwelensi, iziphene zokwenza, kunye neempazamo zokufakelwa kwemishini.
Eyokugqibela yimpazamo yomntu, enxulumene kakhulu nemikhwa yokusebenza komsebenzisi kwaye ikakhulu yenzeka koomatshini abasebenza ngesandla kunye noomatshini abazenzekelayo.
Impazamo yomntu ibandakanya ikakhulu ezi zinto zilandelayo:
1. Fumana impazamo yento yokulinganisa (imiphetho engacacanga kunye ne-burr)
2. Impazamo yokulungiswa kobude be-focal ye-Z-axis (impazamo yomgwebo we-focus point ocacileyo)
Ukongeza, ukuchaneka komatshini wokulinganisa umbono kukwanxulumene ngokusondeleyo nokusetyenziswa kwawo rhoqo, ukugcinwa rhoqo kunye nendawo osetyenziswa kuyo. Izixhobo ezichanekileyo zifuna ukulungiswa rhoqo, zigcine umatshini womile kwaye ucocekile xa ungasetyenziswa, kwaye zigcine kude neendawo ezineengxolo ezinkulu okanye ingxolo enkulu xa uyisebenzisa.
