Izindlela zokulinganisa ubude besiqephu sokusebenza ngemishini yokulinganisa ividiyo ezenzakalelayo

I-VMS, eyaziwa nangokuthiIsistimu Yokulinganisa Ividiyo, isetshenziselwa ukukala ubukhulu bemikhiqizo kanye nesikhunta. Izakhi zokulinganisa zifaka ukunemba kwendawo, ukugxila, ukuqondisa, iphrofayela, ukujikeleza, nobukhulu obuhlobene namazinga ereferensi. Ngezansi, sizokwabelana ngendlela yokulinganisa ubude besiqephu somsebenzi namaphutha okulinganisa sisebenzisa imishini yokulinganisa ividiyo ezenzakalelayo.

Izindlela zokulinganisa ubude be-workpiece nge-othomathikhiimishini yokulinganisa ividiyo:

Isilinganiso sobude be-probe yokuxhumana: Faka i-probe ku-axis engu-Z ukuze ulinganise ubude bocezu lokusebenza usebenzisa i-probe yokuxhumana (kodwa-ke, le ndlela idinga ukungeza imojula yokusebenza kwe-probe ku-2disofthiwe yensimbi yokulinganisa isithombe). Iphutha lokulinganisa lingalawulwa ngaphakathi kwe-5um.

Isilinganiso sobude be-laser okungeyena othintana naye: Faka i-laser ku-axis engu-Z ukuze ulinganise ubude bomsebenzi usebenzisa isikali se-laser esingaxhunywanga (le ndlela futhi idinga ukungeza imojula yokusebenza kwe-laser kusofthiwe yethuluzi lokulinganisa lesithombe engu-2d). Iphutha lokulinganisa lingalawulwa ngaphakathi kwama-5ums.

Indlela yokulinganisa ubude esekelwe esithombeni: Engeza imojuli yokulinganisa ubude ku-VMMisofthiwe, lungisa ukugxila ukuze ucacise indiza eyodwa, bese uthola enye indiza, futhi umehluko phakathi kwezindiza ezimbili ubude obuzokalwa. Iphutha lesistimu lingalawulwa ngaphakathi kwe-6um.

Amaphutha okulinganisa emishini yokulinganisa ividiyo ezenzakalelayo:

Amaphutha esimiso:

Amaphutha ezimiso zemishini yokulinganisa ividiyo ahlanganisa amaphutha abangelwa ukuhlanekezela kwekhamera ye-CCD kanye namaphutha abangelwa ukuhlukahlukaizindlela zokulinganisa. Ngenxa yezici ezifana nokukhiqizwa kwekhamera nezinqubo, kukhona amaphutha ekukhanyeni ukukhanya kwesigameko okudlula kumalensi ahlukahlukene kanye namaphutha endaweni ye-CCD yamachashazi matrix, okuholela ezinhlotsheni ezihlukahlukene zokuhlanekezela kwejometri ohlelweni olubonayo.

Izindlela ezihlukene zokucubungula izithombe ziletha amaphutha okuqashelwa nokulinganisa inani. Ukukhishwa kwe-Edge kubalulekile ekucubungulweni kwesithombe, njengoba kukhombisa i-contour yezinto noma umngcele phakathi kwezindawo ezihlukene zezinto ezisesithombeni.

Izindlela ezihlukene zokukhipha unqenqema ekucubungulweni kwesithombe sedijithali zingabangela ukuhluka okuphawulekayo endaweni efanayo yonqenqema olulinganiselwe, ngaleyo ndlela kuthinte imiphumela yokulinganisa. Ngakho-ke, i-algorithm yokucubungula isithombe inomthelela obalulekile ekunembeni kokulinganisa kwethuluzi, okuyindawo ebalulekile yokukhathazeka esilinganisweni sesithombe.

Amaphutha okukhiqiza:

Amaphutha okukhiqiza emishini yokulinganisa ividiyo ahlanganisa amaphutha enziwe izindlela zokuqondisa namaphutha okufaka. Iphutha elikhulu elikhiqizwe indlela eqondisayo yemishini yokulinganisa ividiyo iphutha lokuma kokunyakaza komugqa wendlela.

Imishini yokulinganisa ividiyo ine-orthogonalxhumanisa izinsimbi zokulinganisaenezimbazo ezintathu ezihambisanayo (X, Y, Z). Izindlela ezisezingeni eliphezulu zokuqondisa ukunyakaza zinganciphisa umthelela wamaphutha anjalo. Uma ukusebenza kokulinganisa kweplathifomu yokulinganisa nokufakwa kwekhamera ye-CCD kuhle kakhulu, futhi ama-engeli awo angaphakathi kwebanga elicacisiwe, leli phutha lincane kakhulu.

Amaphutha okusebenza:

Amaphutha okusebenza kwemishini yokulinganisa ividiyo ahlanganisa amaphutha abangelwa izinguquko endaweni yokulinganisa nezimo (ezifana nokushintsha kwezinga lokushisa, ukushintshashintsha kwamandla kagesi, izinguquko ezimweni zokukhanya, ukuguga kwemishini, njll.), kanye namaphutha aguqukayo.

Ukushintsha kwezinga lokushisa kubangela ukuhluka kobukhulu, ukuma, ubudlelwano bendawo, nezinguquko kumapharamitha wesici esibalulekile sezingxenye zemishini yokulinganisa ividiyo, ngaleyo ndlela kuthinte ukunemba kwethuluzi.

Izinguquko ku-voltage nezimo zokukhanyisa zizothinta ukukhanya kwemithombo yokukhanya engaphezulu nephansi yomshini wokulinganisa ividiyo, okuholela ekukhanyeni kwesistimu okungalingani futhi kubangele amaphutha ekukhishweni konqenqema ngenxa yezithunzi ezisele emaphethelweni ezithombe ezithathiwe. I-Wear idala amaphutha obukhulu, umumo, nawendawo ezingxenyeni ze-umshini wokukala ividiyo, kwandisa ukucaciswa, futhi kunciphisa ukuzinza kokunemba kokusebenza kwethuluzi. Ngakho-ke, ukuthuthukisa izimo zokusebenza zokulinganisa kunganciphisa ngempumelelo umthelela wamaphutha anjalo.
