Nansi indlela Yokuqalisa Amamodeli Wokunyathelisa we-3D we-3D Printing
Ngesikhathi sokuhamba komgwaqo we-3DRV kazwelonke, ngichitha isikhathi esiningi ngithatha izithombe zezinto ezimile ngekhamera yami ye-digital (DSLR). Izinto engangizicabangayo zingenza ama-3D aqoshiwe, kodwa izinto engingafuni ukudweba noma ukuzidweba kusuka ekuqaleni, noma kusuka kusikrini esingenalutho.
Ngifunde ukuthi kungenzeka ukuthatha izithombe eziningi zento, kumaphuzu ahlukene we-vantage, ezungeze into. Ngokuthatha izithombe kule fomethi ye-360 degree, uthatha imininingwane eyanele ukuthi isofthiwe esithuthukisiwe ingafaka lezi zithombe ndawonye kuwe, njenge-3D model. Le ndlela noma inqubo iyaziwa njenge-photogrammetry. Abanye bakubiza ngokuthi izithombe ze-3D.
Nakhu okushiwo i-Wikipedia (noma yiyinkimbinkimbi kakhulu kunezincazelo zami, ngiyakholwa):
"I- Photogrammetry yisayensi yokwenza izilinganiso ezivela ezithombeni, ikakhulukazi ukuze kutholakale izikhundla eziqondile zamaphoyinti asezindaweni ... [Kungase isebenzise izithombe ezisheshayo ngokushesha nokubona okude ukuze kutholakale, kulinganisa futhi urekhodile ukunyakaza okunamandla oku-2-D no-3-D amasimu (bona futhi i-sonar, i-radar, i-lidar njll). I-Photogrammetry idla izilinganiso kusuka ekukuboneni okude futhi imiphumela yokuhlaziywa kwezithombe ibe ngamamodeli wokusebenzisa ulwazi emzamweni wokulinganisa ngokulandelana, ngokunemba okwandayo, okwenziwe, okuyi-3-D okuhambisana nendawo ngaphakathi kwenkambu ecwaningiwe. "
Ngiyathanda incazelo elula kakhulu: Ukuze usebenzise le ncazelo, futhi usebenze, ake ngichaze lokho engikuqondayo futhi nginike amados lapho kufanele khona; I-Autodesk nethimba le-Computing Team lidale isofthiwe ukwenza konke lokhu kube lula futhi okusheshayo. Isofthiwe ivela ku-Autodesk ReCap futhi kune-app ebizwa ngokuthi i-123D Catch eyenza lokhu kwenzeke ngekhamera ye-smartphone nje. Ithimba le-Autodesk ReCap lithanda ukufingqa umqondo wokuthatha okuthile kwezwe lomzimba nokwenza kube yedijithali njenge: Ukuthumba, UkuQula, UkuDala. Benza nge-scanner laser kanye ne-photogrammetry, izindlela ezimbili ezihlukene, kodwa ngigxile ekugcineni kulokhu okuthunyelwe.
Lena ingxenye ekhulayo yokunyathelisa kwe-3D ngoba ikuvumela ukuba udale kusukela ochungechungeni lwezithombe, njengoba ngishilo, kunokuba ufunde iphepha elingenalutho noma isikrini se-digital. Kunezinhlelo zokusebenza eziningi ezingenza lokhu noma into enjengale. Okubili engikusebenza ekubuyekezeni okunye: Fyuse (uhlelo lokusebenza lwe-iOS ne-Android) ne-Project Tango kusuka ku-Google (engibhale ngakho nge-Forbes futhi.) Ungafunda lokho lapha.)
Ukubuka Okusheshayo Kokuthi Kusebenza Kanjani:
Okokuqala, ungasebenzisa ikhamera yedijithali evamile, i-GoPro, noma i-smartphone ukuthatha izithombe ukuthi isofthiwe izokuvumela ukuba uhlanganise ndawonye ibe yi-3D model. Uma wake wasebenzisa umsebenzi we-panoramic ekhamera yedijithali, unombono onzima wokuthi lokhu kuzobukeka kanjani.
Okwesibili, uthatha iqoqo lezithombe zento noma umuntu. Kukhona amathiphu amaningi atholakalayo akusiza ukuthi udale imodeli engcono kunazo zonke ze-3D, kodwa ngcono ikhamera yakho, ngcono imiphumela ye-3D. Ungathatha izinto eziningi noma ngisho nomuntu (uma babambelela kakhulu) nale nqubo "yokubamba kwangempela".
Okwesithathu, isofthiwe yenza konke okunye. Ulayisha izithombe kwi-ReCap yesevisi noma i-123D Catch futhi izogxila lezo zithombe ndawonye ukuze ubone manje izithombe ngokugcwele okubukeka kwesithathu. Kufana ne-Google Street View lapho ungahlela khona indawo yonke - wenza "umbono wakho wesitaladi" kulokhu. I-ReCap izokuvumela ukuba wenze noma konke ngokuzenzekelayo - ukukhetha izindawo zangempela noma izindawo ezithintanayo, kodwa iningi lethu ngeke lenze lokho futhi vumela isofthiwe ukuthi iphakamise kakhulu. I-akhawunti yamahhala ivumela izithombe ezingafika ku-50, ngaphezu kokwanele kumthengi nokusetshenziswa kwebhizinisi elincane.
Ake sixoxe kafushane ngokuthi "qhafaza." Idatha evela ezweni elingokoqobo elithunyelwe ngekhamera yakho lilayishwa efwini (kuthatha amandla amaningi wekhompyutha; ngaphezulu wena ideskithophu yakho ephathekayo / iphathekayo ingabamba) futhi isevisi ye-ReCap Photo yenza sebenzisa. Ideskithophu yeReCap isebenza ngemininingwane yokuskena i-laser, kodwa udinga ifu lomsebenzi omkhulu wokufanisa nokunamathisela izithombe, okungenani okwamanje.
Okokugcina, ngokulayisha okuningi, uzobuyisa imodeli ye-3D engaphansi kwehora. Yisizathu esihle esinamandla sokudweba noma ukudweba ekhasini elingenalutho noma kwesikrini. Ungakwazi ukuskena isithombe sakho ngendlela enhle ukuze uguqule, uguqule, ushintshe, ukusheshisa inqubo yakho yokuklama. Ungathola isigaba "sokudala" ngokushesha kakhulu ngale ndlela.
Nazi ezinye izinsiza ezimbalwa kuwe:
- I-Autodesk ReCap
- Izinhlelo zokusebenza ze-123D ezivela ku-Autodesk
- Ikhasi le-Photogrammetry
- Nansi ividiyo enkulu yenqubo ye-photogrammetry usebenzisa i-GoPro ne-drone ye-UAV.
Enye inguqulo yalokhu okuthunyelwe kuqala ivele kubhulogi lami le-3DRV, eliyisihloko esithi: Kuyini i-Photogrammetry. Ukudalulwa okugcwele: I-Autodesk exhaswe ingxenye ye-3DRV roadtrip yami ngo-2014.
