(2011) akufuna ntchito zithunzi kuti "Mangani Rome mu tsiku" pogwiritsa ntchito 150,000 zithunzi za Rome kulenga kukhazikitsanso 3D a mzinda. Pakuti malo alendo ngati m'bwalo lalikulu la maseŵera panali zithunzi mokwanira Intaneti kubala zitsanzo 3D (Chithunzi 5.10), koma khalidwe la zojambulidwa izi zinali zochepa chifukwa chakuti zithunzi kwambiri anaitenga mu malingaliro omwewo wodziwika bwino, kusiya mbali mwa nyumba unphotographed. Komanso, m'madera ambiri a mzinda, zithunzi sikokwanira analipo. Choncho, ntchito deta anapeza kuchokera chithunzi repositories, sikunali kotheka kuti recreate onse Rome. Koma bwanji ngati odzipereka akhoza m'gulu kusonkhanitsa zithunzi zofunika kwenikweni "Mangani Rome mu tsiku"?

Chithunzi 5,10: A kukhazikitsanso 3-D a m'bwalo lalikulu la maseŵera ku akonzedwa lalikulu mafano 2-D kwa polojekiti "Building Rome mu tsiku". The Triangles kuimira malo omwe zithunzi anatengedwa (Agarwal et al. 2011) .

Kuti athe kutolera akulimbana yaikulu ya photos, Kathleen Tuite ndi anzake anayamba PhotoCity, masewera chithunzi-ikukweza. Womwe wokongola wa PhotoCity kuti kunapezeka ntchito zingakhale yolemetsa ya zosonkhanitsira deta-ikukweza zithunzi mu masewera ngati zochitika zokhudza magulu, nyumba, ndi mbendera (Chithunzi 5.11). Kamangidwe ka PhotoCity komanso elegantly zochimwazo kumathetsa ndi zosankhidwazi ndi deta khalidwe mavuto a eBird ndipo anagawira ntchito zina zosonkhanitsira deta.

Osewera iliyonse pasukulupo akhoza kuyendera zikuchitika la chitsanzo kukhazikitsanso pamalo awo. Ndiye, iwo akanakhoza kupeza mfundo ndi kuika zithunzi kukuza chitsanzo panopa. Mwachitsanzo, ngati chitsanzo panopa Uris Library (pa Cornell) anali patchy kwambiri, player akhoza kupeza mfundo ndi kuika zithunzi latsopano la izo. Otsutsa, zithunzi amene ndakweza ayenera alipo zithunzi zilipo panopa kuti akhoza likakhazikitsidwa, ndi chiwerengero cha mfundo player ndi analandira zachokera ndalama kuti chithunzi chawo anawonjezera chitsanzo panopa. Pomaliza ofufuza ankatha kugwiritsa ntchito zithunzi ndakweza kulenga mkulu kusamvana zitsanzo 3D nyumba pa campuses onse (Chithunzi 5.12).

Chithunzi 5,12: The masewera PhotoCity chinathandiza akatswiri ndi ophunzira kuti akonze apamwamba zitsanzo 3D nyumba pogwiritsa ntchito zithunzi ndakweza ndi gulu (Tuite et al. 2011) .

Kamangidwe ka PhotoCity elegantly zochimwazo kumathetsa mavuto awiri: deta kutsimikiza ndi zosankhidwazi. Choyamba, zithunzi anali linatsimikizidwa ndi zofanana iwo pa zithunzi yapita adali nayenso chikufanana ndi zithunzi yapita njira yonse kubwerera ku zithunzi mbewu amene ndakweza ndi ofufuza. M'mawu ena, chifukwa cha redundancy izi anamanga-, zovuta kwa dongosolo kulandira deta zoipa. Chachiwiri, kugoletsa dongosolo mwachibadwa imaphunzitsa ophunzira kusonkhanitsa chidali osati kwambiri yabwino-deta. Ndipotu, naŵa njira imene osewera anafotokoza ntchito kuti apeze mfundo zina, amene ali ofanana kuti deta lofunika kwambiri (Tuite et al. 2011) :

• "[Ndinayesa] kuyandikira nthawi ya tsiku ndi kuyatsa kuti zithunzi unatengedwa; izi zingawathandize kupewa kukanidwa ndi masewera. Ndi kuti anati, mitambo zabwino kwambiri pochita zinthu ndi ngodya chifukwa wochepa kusiyana anathandiza masewera kuzindikira Masamu zithunzi wanga. "

• "Pamene anali dzuwa, I ntchito kamera wanga odana ndi kugwedeza mbali kulola ndekha zithunzi poyenda mozungulira zone makamaka. Izi anandilola kutenga zithunzi khirisipi pamene alibe kusiya stride wanga. Komanso bonasi: kupatula anthu anandiyang'anitsitsa "!

• "Tengani ndi mafanizo ambiri a nyumba ina ndi 5 megapixel kamera, kubwera kunyumba kugonjera, nthawi zina gigs 5 pa mlungu mphukira, anali yaikulu chithunzi adani strategy. Kukonza zithunzi mafoda kunja zovuta galimoto ndi dera komweko, kumanga, ndiye nkhope ya nyumba anapereka wolowezana bwino kutsogolera uploads. "

mawu awa kwa ophunzira bwanji kuti pamene anapereka ndemanga n'koyenera, akhoza kukhala katswiri kwambiri pa deta chidwi ofufuza.

Cacikulu, zomangidwazo PhotoCity limasonyeza kuti zosankhidwazi ndi deta khalidwe si mavuto akuluakulu mu deta yogawa deta. Komanso, izo zikusonyeza kuti deta anagawira ntchito deta suthera ntchito zimene anthu kale kuchita mulimonse, monga kuonera mbalame. Ndi mamangidwa, odzipereka angalimbikitsidwe kuchita zinthu zina.
