Nayi Njira Yoyambira Zithunzi Zanu Zosindikizira Zojambula Zaka 3D
Pa ulendo waulendo wa 3DRV, ndinakhala nthawi yambiri ndikujambula zithunzi za zinthu zowoneka ndi kamera yanga ya digito (DSLR). Zinthu zomwe ndinkaganiza kuti zingapange zojambula zoopsa za 3D, koma zinthu zomwe sindinkafuna kukoka kapena kuzijambula poyambira, kapena kuchokera pa tsamba lopanda kanthu.
Ndaphunzira kuti n'zotheka kutenga zithunzi zambiri za chinthu, pazithunzi zosiyana, ndikuzungulira chinthu. Pogwiritsa ntchito mafashoni mu fashoni iyi ya madigiri 360, mumatenga mwatsatanetsatane kuti mapulogalamu apamwamba angathe kusonkhanitsa zithunzizi pamodzi, monga 3D model. Njira iyi kapena ndondomeko imadziwika ngati photogrammetry. Ena amachitcha kuti kujambula kwa 3D.
Apa pali zomwe Wikipedia imanena (ngakhale zovuta kwambiri kuposa ndondomeko zanga, ndikukhulupirira):
" Photogrammetry ndi sayansi yopanga zojambula kuchokera ku zithunzi, makamaka pofuna kupeza malo enieni a malo ozungulira ... [Icho] chingagwiritse ntchito kujambula mwamphamvu kwambiri ndi kutulukira kutali kuti tipeze, kuyesa ndi kulemba zovuta zojambula 2-D ndi 3-D minda (onaninso sonar, radar, lidar etc.). Photogrammetry imadyetsa miyeso kuchokera kumadera akutali ndipo zotsatira za kusanthula mafano kukhala zitsanzo zamakono pofuna kuyesa kulingalira bwino, ndi kulondola molondola, zenizeni, 3-D zokambirana zapadera m'munda wofufuzidwa. "
Ndimakonda kufotokozera momveka bwino: Kuti ndigwiritse ntchito tanthawuzo, ndi ndondomeko, ndiroleni ine ndifotokoze zomwe ndimamvetsa ndikupereka komwe kuli koyenera; Autodesk ndi Team Reality Computing adapanga pulogalamuyi kuti apange zonsezi mosavuta komanso mofulumira. Pulogalamuyi imachokera ku Autodesk ReCap ndipo palinso pulogalamu yotchedwa 123D Catch yomwe imapangitsa kuti izi zitheke ndi kamera ya smartphone. Gulu la Autodesk ReCap limakonda kufotokoza mwachidule lingaliro la kutenga chinachake cha dziko lapansi ndikuchipanga digito monga: Kutenga, Kulingalira, Pangani. Amachita ndi kujambulira kwaser ndi photogrammetry, njira ziwiri zosiyana, koma ndimaganizira kwambiri pamapeto awa.
Ichi ndi mbali yofulumira kwambiri yosindikizira ya 3D chifukwa imakupatsani mwayi wojambula kuchokera ku zithunzi zambiri, monga ndatchulira, osati pepala losalemba kapena digito. Pali mapulogalamu ambiri omwe angathe kuchita izi kapena chinachake chonga ichi. Zili ziwiri zomwe ndikugwira ndikupitilizabe: Fyuse (pulogalamu ya iOS ndi Android) ndi Project Tango kuchokera ku Google (zomwe ndalemba za pa Forbes komanso mukhoza kuziwerenga apa)
Zomwe Mwadzidzidzi Zomwe Zimagwira Ntchito:
Choyamba, mungagwiritse ntchito kamera ya digito, GoPro, kapena foni yamakono kuti mujambula zithunzi zomwe pulogalamuyi idzakulolani kuti mugwirizane pamodzi mu 3D model. Ngati munagwiritsirapo ntchito panoramic pa kamera kamera, muli ndi malingaliro ovuta momwe izi ziwonekere.
Chachiwiri, mumatenga zithunzi za chinthu kapena munthu. Pali nsonga zambiri zomwe zikuthandizani kuti muyambe bwino 3D model, koma bwino kamera yanu, bwino zotsatira 3D. Mutha kutenga zinthu zambiri kapena ngakhale munthu (ngati akugwirabe kwambiri) ndi ndondomeko iyi yowona.
Chachitatu, pulogalamuyo imapanga zonse. Mukutsitsa zithunzi ku msonkhano wa ReCap kapena 123D Catch ndipo zidzakongoletsa zithunzizo palimodzi kuti tsopano muone zithunzi muzithunzi zonse zitatu. Zili zofanana ndi Google Street View kumene mungakonze zozungulira malo anu onse - mumadzipanga nokha "street view" kuzungulira chinthucho. ReCap idzakulolani kuti muchite zina kapena zonse mwadongosolo - kusankha malo enieni kapena mawanga omwe amagawana wina ndi mzake, koma ambiri a ife sitingachite zimenezo ndikulola pulojekitiyo kukweza. Akaunti yaulere imapereka zithunzi zopitirira 50, zoposa zokwanira kugula ndi kugulitsa ntchito yaying'ono.
Tiyeni tifotokoze mwachidule za "compute." Dongosolo lochokera ku dziko lapansi lomwe latengedwa kudzera mu kamera yanu limatumizidwa ku mtambo (zimatengera mphamvu zambiri zamagetsi; kwambiri ndiwe kompyuta yanu / laputopu mungathe kugwiritsira ntchito) ndi utumiki wa ReCap Photo umachita ntchito. Dongosolo la reCap ladongosolo limaphatikizapo deta yolumikizira laser, koma mukusowa mtambo wa ntchito yaikulu yofananirana ndi yokongoletsa zithunzi, pakalipano.
Potsirizira, chifukwa cha zambiri zolemba, mudzabwezeretsa 3D model muchepera ola limodzi. Ichi ndi chifukwa chomveka chosajambula kapena kujambula pa tsamba lopanda kanthu kapena pawindo. Mungathe kujambula chithunzi chanu kuti mupange chitsanzo chabwino chomwe mungasinthe, kusintha, kusintha, kuti muthamangitse ndondomeko yanu. Mungathe kufika pa "kulenga" gawo mofulumira njira iyi.
Nazi zina mwazinthu zina zomwe zingakuthandizeni:
- Autodesk ReCap
- 123D Mapulogalamu kuchokera ku Autodesk
- Tsamba la photogrammetry
- Nayi kanema yayikulu ya ndondomeko ya photogrammetry pogwiritsa ntchito goPro ndi drake ya UAV.
Chotsatira china cha positiyi chinawonekera koyamba mu blog yanga ya 3DRV, yomwe inali ndi mutu wakuti: Kodi Photogrammetry ndi Chiyani? Kuwululidwa kwathunthu: Autodesk chothandizira gawo la msewu wanga wa 3DRV mu 2014.
