Isistimu yokuthwebula ukunyakaza kwe-3Direkhodi eliphelele lokunyakaza kwento kumishini yasemkhathini enezinhlangothi ezintathu, ngokomgomo wezinhlobo ezahlukene zokuthwebula ukunyakaza ngomshini, ukuthwebula ukunyakaza kwe-acoustic, ukuthwebula ukunyakaza kwe-electromagnetic,ukuthwebula ukunyakaza kwe-optical, kanye nokuthwebula ukunyakaza kwe-inertial.Imishini yamanje yokuthwebula enyakazayo enezinhlangothi ezintathu emakethe iwubuchwepheshe obubili bakamuva.
Amanye amasu okukhiqiza ajwayelekile ahlanganisa ubuchwepheshe bokuskena izithombe, i-alchemy, ukulingisa, njll.
Ukuthwebula ukunyakaza okubonakalayo.Iningi lokuthwebula okujwayelekile kokunyakaza okubonakalayo okusekelwe ezimisweni zombono wekhompuyutha kungahlukaniswa ngokuthwebula ukunyakaza okususelwe ku-Marker point kanye ne-non-Marker point-based.Ukuthwebula ukunyakaza okusekelwe endaweni yomaka kudinga amaphuzu akhanyayo, aziwa kakhulu ngokuthi amaphoyinti omaka, ukuthi anamathiselwe ezindaweni ezibalulekile zento eqondiwe, futhi kusebenzisa ikhamera ye-infrared enesivinini esiphezulu ukuze ithwebule umkhondo wamaphoyinti akhanyayo entweni eqondiwe, ngaleyo ndlela ibonise. umnyakazo wento eqondiwe emkhathini.Ngokwethiyori, ngephuzu esikhaleni, inqobo nje uma lingabonwa amakhamera amabili ngasikhathi sinye, indawo yephuzu emkhathini ngalo mzuzu inganqunywa ngokusekelwe ezithombeni nemingcele yekhamera ethathwe amakhamera amabili endaweni. umzuzu ofanayo.
Isibonelo, ukuze umzimba womuntu uthwebule ukunyakaza, kuvame ukudingeka ukuthi unamathisele amabhola akhanyayo kuphawu ngalunye lwejoyinti nethambo lomzimba womuntu, futhi uthwebule umzila wokunyakaza wamaphuzu akhanyayo ngamakhamera we-infrared high-speed, bese uhlaziya futhi zicubungule ukuze zibuyisele ukunyakaza komzimba womuntu emkhathini futhi zihlonze ngokuzenzakalelayo ukuma komuntu.
Eminyakeni yamuva, ngokuthuthukiswa kwesayensi yekhompiyutha, enye indlela yephuzu elingelona i-Marker ikhula ngokushesha, futhi le ndlela isebenzisa ngokuyinhloko ukuqashelwa kwesithombe nobuchwepheshe bokuhlaziya ukuhlaziya izithombe ezithathwe yikhompyutha ngokuqondile.Le nqubo iyona engaphansi kakhulu ekuphazamisekeni kwemvelo, futhi okuhlukile njengokukhanya, ingemuva, nokuvala kungase kube nomthelela omkhulu kumphumela wokuthwebula.
I-Inertial Motion Capture
Olunye uhlelo oluvame kakhulu lokuthwebula ukunyakaza lusekelwe kuzinzwa ezingasebenzi (inertial Measurement Unit, IMU) ukuthwebula ukunyakaza, okuyiphakheji ehlanganisiwe ye-chip ibe amamojula amancane aboshwe ezingxenyeni ezihlukahlukene zomzimba, ukunyakaza kwendawo yesixhumanisi somuntu esirekhodwe chip, futhi kamuva yahlaziywa ngama-algorithms ekhompiyutha ngaleyo ndlela yaguqulwa yaba idatha yokunyakaza komuntu.
Ngenxa yokuthi ukuthwebula okune-inertial kugxilwe ikakhulukazi ku-link point inertial sensor (IMU), ngokuhamba kwenzwa ukuze kubalwe ukuguqulwa kwendawo, ngakho ukuthwebula okune-inertial akuthintwa kalula imvelo yangaphandle.Kodwa-ke, ukunemba kokuthwebula kwe-inertial akukuhle njengokuthwebula optical uma kuqhathaniswa imiphumela.
