5.4.2 PhotoCity

PhotoCity daws cov ntaub ntawv zoo thiab zauv teeb meem nyob rau hauv faib cov ntaub ntawv sau.

Cov Web sites xws li Flickr thiab Facebook pab cov neeg muab cov duab nrog lawv cov phooj ywg thiab tsev neeg, thiab lawv kuj tsim cov duab loj loj uas muaj duab uas siv tau rau lwm cov hom phiaj. Piv txwv li, Sameer Agarwal thiab cov npoj yaig (2011) tau sim siv cov duab no rau "Tsim Rome nyob rau ib hnub" los ntawm repurposing 150,000 duab ntawm Rome los tsim kev txuag 3D ntawm lub nroog. Rau qee lub tsev yees duab hnyav - xws li Coliseum (daim duab 5.10) - cov neeg tshawb xyuas tau ib feem zoo, tiam sis qhov kev tsim txom tau raug vim ntau cov duab raug coj los ntawm tib lub cim kev pom zoo, tawm hauv cov feem ntawm cov tsev tsis muaj teeb meem. Yog li, cov duab ntawm duab thaij duab tsis txaus. Tab sis yuav ua li cas yog tias cov neeg tuaj pab dawb yuav tsum tau sau npe los sau cov duab uas tsim nyog los txhawb cov uas twb muaj lawm? Xav rov qab rau cov duab zoo li nyob rau hauv tshooj 1, ua li cas yog tias cov dluab duab npaj txhij tuaj yeem tsim muaj los ntawm cov duab saib xyuas?

Daim duab 5.10: Kev kho dua 3D ntawm Coliseum los ntawm txheej txheem 2D ntawm qhov project "Lub Tsev Lom Zem Nyob Ib Hnub." Daim duab peb sab sawv cev ntawm cov duab uas tau rho tawm cov duab. Lo lus tso cai los ntawm kev tso cai los ntawm html version ntawm Agarwal et al. (2011) .

Nyob rau hauv thiaj li yuav pab kom cov sau ntawm coob tus duab ntawm cov duab, Kathleen Tuite thiab npoj yaig tsim PhotoCity, yees duab yees duab. PhotoCity tau muab cov ntaub ntawv khaws cia-duab tso-ua duab zoo-xws li kev ua si zoo nkauj nrog pawg, castles, thiab tus chij (daim duab 5.11), thiab nws tau pib ua kom tsim tau 3D kev tsim kho ntawm ob lub tebchaws: Cornell University thiab University ntawm Washington. Cov kws tshawb fawb pib ua tus txheej txheem los ntawm kev xa cov duab duab los ntawm qee lub tsev. Tom qab ntawd, players ntawm txhua lub tsev kawm ntawv tau ntsuam xyuas lub sijhawm tam sim no ntawm kev txhim kho thiab tau txais cov ntsiab lus los ntawm upload dluab rau kev txhim kho kev txhim kho. Piv txwv li, yog hais tias kev rov kho dua tshiab ntawm Uris Library (ntawm Cornell) yog ib qho khoob khoob heev, ib tug neeg ua ntawv tau txais cov points los ntawm upload cov duab tshiab ntawm nws. Ob yam ntxwv ntawm cov txheej txheem no yog qhov tseem ceeb heev. Ua ntej, tus naj npawb ntawm cov ntsiab lus ib tug neeg uas tuaj yeem tau txais raws li qhov lawv yees duab ntxiv rau kev tsim kho. Thib ob, cov duab uas tau muab tso rau sib tshooj nrog cov kev tsim kho tam sim no es lawv thiaj li muaj peev xwm ua tau. Thaum kawg, cov kws tshawb fawb tau tsim cov qauv ntawm cov tsev kawm ntawv siab ntawm ob lub tsev kawm ntawv (daim duab 5.12).

Daim duab 5.11: PhotoCity muab txoj hauj lwm uas yuav khaws cov ntaub ntawv (ie, uploading photos) thiab muab tso rau hauv kev ua si. Sau dua los ntawm kev tso cai los ntawm Tuite et al. (2011) , daim duab 2.

Daim duab 5.12: Lub yees duab ntawm PhotoCity tau tshawb nrhiav cov neeg tshawb nrhiav thiab cov neeg koom nrog tsim cov qauv 3D zoo ntawm cov vaj tse uas siv duab los ntawm cov neeg tuaj koom. Sau dua los ntawm kev tso cai los ntawm Tuite et al. (2011) , daim duab 8.

Tus tsim ntawm PhotoCity tau daws ob qho teeb meem uas feem ntau tshwm sim hauv cov ntaub ntawv khaws cia: cov ntawv pov thawj thiab kev kuaj. Ua ntej, cov duab tau tso cai los ntawm lawv muab cov duab qub dhau los, piv tau cov duab qub dhau los rau tag nrho cov duab rov qab rau cov duab cov duab uas tau muab los ntawm cov neeg tshawb xyuas. Ua lwm yam lus, vim yog qhov teeb meem uas tau ua no, nws nyuaj heev rau ib tug neeg yuav tsum tso duab ntawm lub tsev tsis ncaj, tsis hais los yog txhob txwm. No tsim feature txhais tau hais tias lub system tiv thaiv nws tus kheej tawm tsam cov ntaub ntawv tsis zoo. Qhov thib ob, cov kev sib tw tau txais kev cob qhia cov neeg tuaj yeem sau cov nqi tshaj plaws-tsis yog qhov yooj yim tshaj-cov ntaub ntawv. Qhov tseeb, ntawm no yog qee qhov tswv yim uas cov players piav qhia kom siv tau cov ntsiab lus ntxiv, uas yog sib npaug ntawm cov ntaub ntawv tseem ceeb (Tuite et al. 2011) :

• "[Kuv sim] kwv lub sij hawm ntawm ib hnub thiab lub teeb pom kev zoo uas ib co duab raug coj; qhov no yuav pab tiv thaiv kom txhob rejection los ntawm qhov kev ua si. Cov uas hais tias, pos huab hnub yog cov zoo tshaj plaws nyob deb thaum soj ntsuam nrog cov ces kaum vim hais tias tsawg zoo pab qhov kev ua si daim duab tawm lub geometry los ntawm kuv cov duab. "

• "Thaum nws yog tshav ntuj, kuv siv kuv lub koob yees duab lub anti-co nta cia rau kuv tus kheej coj cov duab thaum taug kev nyob ib ncig ntawm ib tug zoo ua noj. Qhov no pub kuv mus muab crisp duab thaum tsis muaj nres kuv stride. Tsis tas li ntawd lawm: tsawg tus neeg stared ntawm kuv! "

• "Noj ntau cov duab ntawm ib tug lub tsev uas muaj 5 megapixel lub koob yees duab, ces los tsev xa, tej thaum mus txog rau 5 gigs rau ib tug weekend tua, yog thawj yees duab capture zoo. Workers cov duab nyob rau lwm hard drive folders los ntawm tsev kawm ntawv cheeb tsam, lub tsev, ces lub ntsej muag ntawm lub tsev muab zoo hierarchy structure uploads. "

Cov nqe lus no qhia tau tias thaum cov neeg tuaj koom nrog cov tswv yim tsim nyog, lawv tuaj yeem dhau los ua tus kws tshaj lij ntawm cov ntaub ntawv khaws tseg rau cov neeg tshawb xyuas.

Zuag qhia tag nrho, PhotoCity project qhia tau hais tias kev kuaj thiab cov ntaub ntawv zoo tsis yog teeb meem insurmountable hauv cov ntaub ntawv khaws cia. Tsis tas li ntawd, nws qhia tau hais tias cov ntaub ntawv faib cov ntaub ntawv yog tsis tag rau cov haujlwm uas tib neeg twb ua lawm, xws li saib cov noog. Nrog rau txoj kev tsim, tuaj yeem txhawb zog siab ua lwm yam thiab.
