5.4.2 PhotoCity

PhotoCity ukuzixazulula izinga idatha kanye izibonelo zalokho izinkinga basakaza iqoqo idatha.

Amawebhusayithi ezifana Flickr kanye Facebook abantu bakwazi ukwabelana izithombe nabangani kanye nemindeni yabo, kodwa futhi adale yokugcina elikhulu izithombe engasetshenziswa ezinye izinjongo. Ngokwesibonelo, Agarwal et al. (2011) ezama ukusebenzisa lezi zithombe: "Ngakhele eRoma Day" ngokusebenzisa 150,000 izithombe eRoma ukudala ukuvuselelwa komuzi 3D. Ngoba izingosi izivakashi like eColiseum kwakukhona izithombe ngokwanele inthanethi ukuze akhiqize onobuhle 3D (Figure 5.10), kodwa izinga lezi emifanekisweni yayiba iqiniso lokuthi izithombe iningi ezathathwa imibono efanayo yisakhiwo sodumo, kusale izingxenye zezakhiwo unphotographed. Ngaphezu kwalokho, izingxenye kakhulu emzini, izithombe akwanele zazikhona. Ngakho, besebenzisa imininingwane etholakele kusuka photo yokugcina, kwakungenakwenzeka ukuba lokuphinda zonke waseRoma. Kodwa, kuthiwani uma amavolontiya babengase wacela ukuqoqa izithombe ezidingekayo ukuze "Yakha eRoma Day" ngempela?

Figure 5.10: A 3-D ukuvuselelwa Coliseum kusuka neqoqo elikhulu izithombe 2-D project "Building eRoma Day". Aboncantathu bamele izindawo kusukela lapho izithombe zathathwa (Agarwal et al. 2011) .

Ukuze sikwazi the iqoqo okubhekiswe yesibalo esikhulu izithombe, uKathleen Tuite kanye nozakwabo athuthukile PhotoCity, umdlalo photo-ukulayisha. Esinye isici amahle ka PhotoCity wukuthi laphendulela umsebenzi okunamandla kanzima data collection-ukulayisha izithombe-ibe umsebenzi umdlalo-like ezihilela amaqembu, izinqaba, futhi amafulegi (Figure 5.11). Luhlakasimo PhotoCity futhi enhle ukuzixazulula izibonelo zalokho futhi izinga idatha ekubhekaneni nezinselelo zokukhuphula izinga eBird kanye nezinye basakaza iqoqo idatha amaphrojekthi.

Figure 5.11: PhotoCity waphenduka lo msebenzi okunamandla kanzima ukuqoqa idatha (ie, izithombe nokulayisha) kanye yaba umdlalo (Tuite et al. 2011) .

PhotoCity kwase kuqala atshalwa sikwazi kabusha amanyuvesi amabili 3D: Cornell University kanye University of Washington. Abadlali at campus ngalunye lwalungaba ukuzohlola isimo samanje imodeli kabusha campus yabo. Khona-ke, babekwazi uthole amaphuzu by ukulayisha izithombe letitawenta kwandze indlela yamanje. Ngokwesibonelo, uma indlela yamanje ye ama-URL Library (at Cornell) kwaba patchy kakhulu, umdlali angazuza amaphuzu by ukulayisha izithombe ezintsha of it. Ngalokujulile, izithombe alayishiwe kumelwe abaphila ne izithombe ezikhona ukuze bakwazi ukuba sasebenza, futhi inani lamaphuzu umdlali wathola kusekelwe lemali isithombe sabo sibe sibi nakakhulu indlela yamanje. Ekugcineni, abacwaningi sakwazi ukusebenzisa lezi zithombe alayishiwe ukudala isinqumo eliphezulu 3D amamodeli we izakhiwo on kokubili esewonke (Figure 5.12).

Figure 5.12: Umdlalo PhotoCity kwasiza abacwaningi kanye ababambiqhaza ukudala eliphezulu 3D amamodeli we izakhiwo usebenzisa izithombe alayishiwe ababambiqhaza (Tuite et al. 2011) .

Luhlakasimo PhotoCity enhle ukuzixazulula izinkinga ezimbili: kwedatha kanye izibonelo zalokho. Okokuqala, izithombe sasebenza ngokufanisa them against izithombe odlule okwakusendlini baphendukela ifaniswe izithombe odlule yonke indlela emuva izithombe imbewu alayishiwe abacwaningi. Ngamanye amazwi, ngenxa yalesi komsebenzi esakhelwe, kunzima kakhulu ohlelweni ukwamukela idatha ezimbi. Okwesibili, uhlelo amagoli ngokwemvelo siqeqesha ababambiqhaza ukuqoqa elikhulu-hhayi kakhulu elula-data kakhulu. Empeleni, lapha kukhona amanye amasu ukuthi abadlali ezichazwe usebenzisa ukuze uthole amaphuzu engeziwe, okuyinto okulingana ukuqoqa idatha ligugu (Tuite et al. 2011) :

• "[Mina wazama] zazikuphi isikhathi sosuku kanye ukukhanyisa ukuthi abanye zithombe zathathwa; lokhu kuzomsiza ukuvimbela ukungamukeleki umdlalo. Ngemva kwalokho wathi: liguqubele zazingcono kakhulu kakhulu lapho sisebenzelana emagumbini ngoba Ngokuphambene kancane wasiza sibalo umdlalo izibalo zama-engela esuka izithombe zami. "

• "Kwathi libalele, mina ezisetshenziswa izici anti-shake ikhamera yami ngizivumele ukuba athathe izithombe ngenkathi ehamba azungeze indawo ethile. Lokhu wangivumela ukuba izithombe omnandi nakuba ayengenalo ukuyeka igxathu yami. Futhi ibhonasi: kancane abantu bebambe kimi "!

• "Ukuthatha izithombe eziningi kwesinye isakhiwo 5 megapixel ikhamera, ke efika ekhaya engafuni ukuzithoba, ngezinye izikhathi kuze 5 Gigs on sicu ngempelasonto, kwaba eyinhloko esithombeni lungabanjwa isu. Ukuhlela izithombe kwi-yangaphandle hard drive amafolda by campus esifundeni, ekwakheni, khona-ke ubuso wokwakha enikeziwe esigabeni sabaphathi ezinhle ukuhlela ukulayisha. "

Lezi izitatimende abahlanganyeli zibonisa ukuthi lapho zinikwa kona impendulo kufaneleka, angase abe uchwepheshe impela ekuqoqeni idatha of interest abacwaningi.

Sekukonke, le project PhotoCity kubonisa ukuthi izibonelo zalokho nekhwalithi yedatha akuzona izinkinga ze zingangentaba e iqoqo distribution idatha. Ngaphezu kwalokho, libonisa ukuthi idatha basakaza iqoqo amaphrojekthi azigcini imisebenzi lokho abantu abakwenzayo kwabanye vele kakade, njengalowo ukubukela izinyoni. With the design kwesokudla, amavolontiya angakhuthazwa ukuba benze ezinye izinto kakhulu.
