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 isetyenziswa ikakhulu kwintsimi yokulinganisa 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.
