Iindlela zokulinganisa ubude bomsebenzi kunye noomatshini bokulinganisa ividiyo ngokuzenzekelayo

I-VMS, ekwaziwa njengeInkqubo yoMlinganiselo weVidiyo, isetyenziselwa ukulinganisa imilinganiselo yeemveliso kunye nokubumba. Izinto zokulinganisa ziquka ukuchaneka kwendawo, ukugxila, ukuthe tye, iprofayili, ukungqukuva, kunye nemilinganiselo enxulumene nemigangatho yereferensi. Apha ngezantsi, siza kwabelana ngendlela yokulinganisa ubude bomsebenzi kunye neempazamo zomlinganiselo kusetyenziswa oomatshini bokulinganisa ividiyo abazenzekelayo.

Iindlela zokulinganisa ubude bomsebenzi ngokuzenzekelaoomatshini bokulinganisa ividiyo:

Umlinganiselo wobude boqhakamshelwano: Nyusa iprobe kwi-Z-axis ukulinganisa ubude bomsebenzi usebenzisa iprobe yoqhagamshelwano (nangona kunjalo, le ndlela ifuna ukongeza imodyuli yomsebenzi weprobe kwi-2disoftware isixhobo sokulinganisa umfanekiso). Impazamo yokulinganisa inokulawulwa ngaphakathi kwe-5um.

Umlinganiselo wobude belaser ongaqhagamshelwanga: Faka i-laser kwi-Z-axis ukulinganisa ubude bomsebenzi usebenzisa umlinganiselo we-laser ongaqhagamshelani naye (le ndlela ifuna ukongeza imodyuli yomsebenzi we-laser kwi-software yesixhobo sokulinganisa umfanekiso we-2d). Impazamo yokulinganisa inokulawulwa ngaphakathi kwe-5ums.

Indlela yokulinganisa ubude obusekwe kumfanekiso: Yongeza imodyuli yomlinganiselo wobude kwiVMMisoftware, lungisa ugxininiso ukucacisa indiza enye, emva koko ufumane enye inqwelomoya, kwaye umahluko phakathi kwezi nqwelomoya zimbini bubude obunokulinganiswa. Impazamo yenkqubo inokulawulwa ngaphakathi kwe-6um.

Iimpazamo zokulinganisa koomatshini bokulinganisa ividiyo abazenzekelayo:

Iimpazamo zomgaqo:

Iimpazamo zomgaqo womatshini wokulinganisa ividiyo ziquka iimpazamo ezibangelwa ukuphazamiseka kwekhamera yeCCD kunye neempazamo ezibangelwa ngokwahlukileyoiindlela zokulinganisa. Ngenxa yezinto ezifana nokuveliswa kwekhamera kunye neenkqubo, kukho iimpazamo kwi-refraction yokukhanya kwesiganeko esidlula kwiilensi ezahlukeneyo kunye neempazamo kwindawo ye-CCD ye-dot matrix, ekhokelela kwiindidi ezahlukeneyo zokuphazamiseka kwejometri kwinkqubo ye-optical system.

Iindlela ezahlukeneyo zokucwangcisa imifanekiso zizisa ukuqondwa kunye neempazamo zobungakanani. I-Edge extraction ibalulekile ekusebenzeni komfanekiso, njengoko ibonisa i-contour yezinto okanye umda phakathi kweendawo ezahlukeneyo zezinto kumfanekiso.

Iindlela ezahlukeneyo zokutsalwa komphetho ekusetyenzweni komfanekiso wedijithali zinokubangela ukuguquguquka okubalulekileyo kwindawo elinganiselweyo yomda, ngaloo ndlela kuchaphazela iziphumo zokulinganisa. Ngoko ke, i-algorithm yokulungiswa komfanekiso inempembelelo ebalulekileyo ekuchanekeni kokulinganisa kwesixhobo, eyona nto igxininisekile kwinkxalabo yokulinganisa umfanekiso.

Iimpazamo zokwenziwa kwemveliso:

Iimpazamo zokuvelisa koomatshini bokulinganisa ividiyo ziquka iimpazamo ezenziwe ngeendlela ezikhokelayo kunye neempazamo zokufakela. Eyona mpazamo iphambili eyenziwe sisikhokelo soomatshini bokulinganisa ividiyo yimpazamo yokumisa intshukumo yendlela.

Oomatshini bokulinganisa ividiyo ba-orthogonallungelelanisa izixhobo zokulinganisangeezembe ezintathu ezijikelezayo (X, Y, Z). Iindlela ezikumgangatho ophezulu zokukhokela iintshukumo zinokunciphisa impembelelo yezo mpazamo. Ukuba ukusebenza komgangatho weqonga lokulinganisa kunye nokufakwa kwekhamera yeCCD kugqwesileyo, kwaye ii-angles zabo zingaphakathi koluhlu oluchaziweyo, le mpazamo incinci kakhulu.

Iimpazamo zokusebenza:

Iimpazamo zokusebenza koomatshini bokulinganisa ividiyo ziquka iimpazamo ezibangelwa utshintsho kwimo yokulinganisa kunye neemeko (ezifana nokutshintsha kweqondo lokushisa, ukuguquguquka kombane, utshintsho kwiimeko zokukhanyisa, ukuguga kwendlela, njl.), kunye neempazamo eziguqukayo.

Utshintsho lobushushu lubangela ubungakanani, imilo, utshintsho lobudlelwane bendawo, kunye notshintsho kwiiparamitha zeempawu ezibalulekileyo zamacandelo oomatshini bokulinganisa ividiyo, ngaloo ndlela kuchaphazela ukuchaneka kwesixhobo.

Utshintsho kwi-voltage kunye neemeko zokukhanyisa kuya kuchaphazela ukukhanya kwemithombo yokukhanya ephezulu kunye nesezantsi yomatshini wokulinganisa ividiyo, okukhokelela ekukhanyeni kwenkqubo engalinganiyo kunye nokubangela iimpazamo ekutsalweni komphetho ngenxa yezithunzi ezishiywe emaphethelweni emifanekiso ethathiweyo. Ukunxiba kubangela iimposiso zobukhulu, imilo, kunye nezokuma kwiindawo zeumatshini wokulinganisa ividiyo, kwandisa ukukhutshwa, kunye nokunciphisa ukuzinza kokuchaneka kokusebenza kwesixhobo. Ngoko ke, ukuphucula iimeko zokusebenza zokulinganisa kunokunciphisa ngokufanelekileyo impembelelo yeempazamo ezinjalo.
