Umshini Wokulinganisa Umbonoiyithuluzi lokulinganisa isithombe esibonakalayo esinembile kakhulu, elisetshenziswa kabanzi ekulinganisweni kwezingxenye ezahlukahlukene zokunemba.
1. Incazelo kanye nokuhlukaniswa
Ithuluzi lokulinganisa isithombe, elaziwa nangokuthi i-image precision plotter kanye nethuluzi lokulinganisa i-optical, liyithuluzi lokulinganisa elinokunemba okuphezulu elakhiwe ngokusekelwe kuphrojektha yokulinganisa. Lithembele kubuchwepheshe bokulinganisa isikrini sekhompyutha kanye nesofthiwe enamandla yokubala i-spatial geometry ukuthuthukisa indlela yokulinganisa yezimboni kusukela ekulinganisweni kwe-optical projection yendabuko kuya ekulinganisweni kwesikrini sekhompyutha ngokusekelwe enkathini yesithombe sedijithali. Izinsimbi zokulinganisa isithombe zihlukaniswe kakhulu zibe izinsimbi zokulinganisa isithombe ezizenzakalelayo ngokuphelele (ezaziwa nangokuthi i-CNC imagers) kanye nezinsimbi zokulinganisa isithombe ngesandla.
2. Isimiso sokusebenza
Ngemva kokuba ithuluzi lokulinganisa isithombe lisebenzise ukukhanya okungaphezulu noma ukukhanya kwe-contour ukuze kukhanye, lithwebula isithombe sento okufanele ilinganiswe ngelensi ye-zoom objective kanye nelensi yekhamera, bese lidlulisela isithombe esikrinini sekhompyutha. Ngemuva kwalokho, ama-crosshair evidiyo akhiqizwa yijeneretha ye-crosshair esibukweni asetshenziswa njengereferensi yokuqondisa nokulinganisa into okufanele ilinganiswe. Irula le-optical liqhutshwa ukuthi lihambe eziqondisweni ze-X kanye ne-Y yibhentshi lokusebenza, bese iprosesa yedatha enemisebenzi eminingi icubungula idatha, bese isofthiwe isetshenziswa ukubala nokuqedela ukulinganisa.
3. Ukwakheka kwesakhiwo
Umshini wokulinganisa isithombe uqukethe ikhamera yombala ye-CCD enesinqumo esiphezulu, ilensi eqondile yokukhulisa eguquguqukayo njalo, isibonisi sombala, ijeneretha yevidiyo ehlanganisa izinwele, irula eliqondile eliqondile, iprosesa yedatha enemisebenzi eminingi, isofthiwe yokulinganisa idatha ye-2D kanye nebhentshi lokusebenzela elinembile kakhulu. Lezi zingxenye zisebenza ndawonye ukuqinisekisa ukunemba nokuzinza kwemiphumela yokulinganisa.
Njengethuluzi lokulinganisa isithombe esibonakalayo elinembile kakhulu, elingathintani, futhi elizenzakalelayo kakhulu, uMshini Wokulinganisa Umbono udlala indima ebaluleke kakhulu ekukhiqizeni kwesimanje. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokwanda okuqhubekayo kwezicelo, sinesizathu sokukholelwa ukuthi uzobonisa inani lawo eliyingqayizivele emikhakheni eminingi.
