Umahluko phakathi kwesixhobo sokulinganisa umfanekiso kunye nokulungelelanisa umatshini wokulinganisa

Ukusuka kwimbono yomlinganiselo we-2d, kukho iisixhobo sokulinganisa umfanekiso, eyenziwa ngokudibanisa i-optical projection kunye nobuchwepheshe bekhompyutha. Iveliswa ngesiseko somfanekiso wedijithali weCCD, kuxhomekeke kwitekhnoloji yokulinganisa isikrini sekhompyuter kunye nezakhono zesoftware enamandla yokubala kwejometri yendawo. Kwaye ukuba isuka kumbono wesithuba esine-dimensional ezintathu, sisixhobo sokulinganisa udidi oluthathu. Ngokuqokelelwa kwamaxabiso olungelelwaniso lwesithuba, ukuwafaka kwizinto zomlinganiselo, kunye nokubala idatha efana nokunyamezelwa kwendawo ngokusebenzisa i-algorithms.

1. Umgaqo womatshini uhlukile
Ukulinganisa umfanekiso kukuchaneka okuphezuluisixhobo sokulinganisa esibonayoyenziwe yiCCD, irula yegrayiti nezinye izinto. Igqiba inkqubo yokulinganisa ngokusekelwe kwiteknoloji yombono womatshini kunye nolawulo oluchanekileyo lwe-micron. Ngexesha lokulinganisa, iya kuhanjiswa kwikhadi lokufumana idatha yekhompyuter nge-USB kunye ne-RS232 imigca yedatha, kwaye isiginali ye-optical iya kuguqulwa ibe ngumqondiso wombane, emva koko umfanekiso uya kubonakaliswa kwikhompyuter ngomfanekiso. isoftware yesixhobo sokulinganisa, kwaye umsebenzisi uya kusebenzisa imawusi ukwenza umlinganiselo okhawulezayo kwikhompyuter.
Umatshini wokulinganisa oneendlela ezintathu. Inkqubo yokulinganisa i-axis emithathu ibala ulungelelwaniso (X, Y, Z) kwindawo nganye yendawo yokusebenza kunye neZixhobo zokulinganisa okusebenzayo.

2. Imisebenzi eyahlukeneyo
Isixhobo sokulinganisa esine-dimensional-dimensional sisetyenziswa ikakhulu kwibala lokulinganisa inqwelomoya emacala mabini, njengoomatshini abathile, i-electronics, hardware kunye namanye amashishini. Abo banentloko yokulinganisa banokulinganisa imilo elula kunye nokunyamezela isikhundla, njengokutya, ukuma, njl.
Isixhobo sokulinganisa esine-dimensional-dimensional igxile kakhulu kwimilinganiselo emithathu-dimensional, kwaye inokulinganisa ubungakanani, ukunyamezela imilo kunye ne-free-form surface yamalungu omatshini anemilo enzima.
