Ngaba ukhe wazibuza ukuba zenziwa njani iimodeli ze-3D zezakhiwo, imbonakalo yomhlaba okanye abantu? Okanye unokulinganisa njani imilinganiselo yento okanye isakhiwo ngaphandle kokuba ube khona ngokwasemzimbeni? Impendulo yi-3D photogrammetry, ubuchule obuvumela ukufumana ulwazi olunemigangatho emithathu ukusuka kwiifoto.
Ifotogrammetry ye-3D isekwe kumgaqo weparallax, olulutshintsho olubonakalayo kwindawo yento xa ijongwe ukusuka. izimvo ezahlukeneyo. I-software ye-Photogrammetry inoxanduva lokulungelelanisa, ukuthumela imiyalezo, kunye nokuthungatha imifanekiso ukwenza imodeli ye-3D enokujongwa, ihlelwe, okanye iprintwe. Kweli nqaku siza kuchaza ukuba yintoni i-3D photogrammetry, indlela yokusebenzisa kunye nendlela yokuqalisa ngesoftware yefotogrammetry.
Yintoni i-3D photogrammetry kwaye yenzelwe ntoni?
La Ifotogrammetry ye3D bubuchule obuvumelayo ulwazi olunemigangatho emithathu izinto, izakhiwo okanye imiboniso evela kwiifoto. Ibandakanya ukuthabatha imifanekiso emininzi ebekwe phezulu kwiindawo ezahlukeneyo zokujonga kunye nokuyilungisa ngesoftware yefotogrammetry ekhupha ulwazi lwejometri kumfanekiso ngamnye, njengokumila, umthamo kunye nobunzulu bento. Yena isoftware yefotogrammetry uyakwazi ukulungelelanisa, ukuthungwa kunye nemesh imifanekiso ukwenza imodeli ye-3D.
Ifotogrammetry ye-3D sisixhobo esiluncedo kakhulu kubakhi, iinjineli, abavavanyi kunye neekontraki, njengoko ibavumela ukuba benze iimephu ze-topographic, iingqimba zamafu, i-mesh okanye imizobo esekwe kwihlabathi lokwenyani. Ikwayeyona ndlela ilula yoku Ukuskena kwe-3D ngaphandle kwesidingo sezixhobo ezibizayo, ngoko isetyenziselwa ukuskena izinto ezincinci kunye nobuso babanye abantu ukwenza iimodeli ezincinci.
iintlobo zefotogrammetry
Ifotogrammetry yomoya: Yinkqubo yokusebenzisa inqwelomoya okanye iidroni ukuvelisa iifoto zasemoyeni ezinokujikwa zibe yimodeli ye3D okanye imephu yedijithali. Iidrones zenze ukuba kube lula ukubamba iindawo ekunzima ukufikelela kuzo okanye ezingafikelelekiyo apho uphando lwemveli lunokuba yingozi okanye lungenzeki. Ifotogrammetry yasemoyeni isetyenziselwa ubukhulu becala ukwenza iimephu kunye nemifuziselo yomhlaba kuphuhliso lobunjineli, iziseko ezingundoqo, ezolimo okanye iiprojekthi zokusingqongileyo.
Ifotogrammetry yasemoyeni intsonkothe ngakumbi kuneyomhlaba, kuba ingaziwa indawo okanye indlela ikhamera emele ngayo ngexesha lokudubula. Ngenxa yesi sizathu, inkqubo yokulawula iyafuneka evumela ukuba i-georeferencing imifanekiso ibe neendawo zokuxhasa phantsi. Ukongezelela, ukugqwesa okubangelwa yimbono, umoya, kunye nokuhamba kufuneka kuthathelwe ingqalelo.
ifotogrammetry yasemhlabeni: Oku kuxa imifanekiso ithathwa kusetyenziswa ikhamera ephathwa ngesandla okanye ixhonywe kwitripod okanye ipali. Injongo yale ndlela ayikokwenza iimephu zembonakalo yendawo, kodwa yenza imifuziselo ye-3D yento encinci. Ifotogrammetry yomhlaba isetyenziselwa iinjongo ezifana noyilo lwesakhiwo kunye nokuhlaziywa, ukugcinwa kwelifa ledijithali, ukuskena kwe-3D yezinto okanye abantu, okanye ulawulo lomgangatho kunye nokuguqulwa.
Ifotogrammetry yomhlaba ilula kune-eriyali, kuba indawo kunye nokuqhelaniswa kwekhamera kwaziwa kwishothi nganye. Nangona kunjalo, kufuneka kuthathelwe ingqalelo ngokukhanya, ukugqithelana kunye nesisombululo semifanekiso ukufumana iziphumo ezilungileyo. Kwakhona izinto ezihambayo kufuneka ziphetshwe okanye ufihle iindawo zento okanye umboniso.
Uyisebenzisa njani isoftware yefotogrammetry
Isoftware yefotogrammetry yinkqubo enoxanduva lokucubungula imifanekiso kunye nokuvelisa imodeli ye-3D. Kukho iinketho ezahlukeneyo zesoftware, zombini zisimahla kwaye zihlawulwe, ezibonelela ngemisebenzi eyahlukeneyo kunye namanqanaba obunzima. Eminye imizekelo yile ReCap, Agisoft Metashape, Meshroom okanye Pix4D.
Ukusetyenziswa kwesoftware yefotogrammetry kuxhomekeke kuhlobo kunye nefomathi yemifanekiso, injongo kunye nomgangatho wemodeli ye-3D, kunye nenkqubo ekhethiweyo. Nangona kunjalo, amanyathelo asisiseko ngala:
- ngenisa ngaphandle imifanekiso kwisoftware kwaye uvumele inkqubo ilungelelanise kwaye ivelise ilifu lamanqaku.
- Cokisa ilifu lencopho ukususa ingxolo namachaphaza angeyomfuneko.
- Yenza umnatha wepolygon ukusuka kwilifu lendawo kwaye usebenzise ukuthungwa okusekwe kwiifoto zokuqala.
- Thumela imodeli ye-3D kwifomathi ehambelanayo nezinye iinkqubo ezifana neRevit, AutoCAD okanye iBlender.
Ezinye iinkqubo zibonelela ngeempawu ezongezelelweyo ezifana nezi:
- Lungisa ukugqwetheka kwejometri kunye nemifanekiso ye-radiometric.
- Georeference imifanekiso ngolungelelwaniso lweGPS okanye iindawo zolawulo.
- yenza ii-orthophotos, iimephu okanye imigca yecontour esuka kwimodeli ye-3D.
- Faka izihluzi, ukusika okanye ukuhlelwa kwimodeli ye-3D.
- sebenzisa algorithms ngokusekelwe kubukrelekrele bokwenziwa ukuphucula inkqubo.
Ungaqala njani ngokubamba ngokwenyani
Ukuthathwa kwenyani yinkqubo yokuskena into, isakhiwo, okanye indawo kunye nokuvelisa imodeli yedijithali. Ukuqala ukubamba ngokwenyani kufuneka:
- Ikhamera yedijithali okanye i-smartphone enekhamera.
- Isoftware yefotogrammetry njenge ReCap, Agisoft Metashape, Meshroom okanye Pix4D.
- Ikhompyutha enomthamo owaneleyo ukucubungula imifanekiso.
Amanyathelo asisiseko ngala:
- Thatha imifanekiso yaloo nto okanye indawo evela kwii-engile ezahlukeneyo kunye nemigama, ukuqinisekisa ukuba kukho ukuhlangana okwaneleyo phakathi kwazo.
- ngenisa iifoto kwisoftware yefotogrammetry kwaye uvumele inkqubo ilungelelanise kwaye ivelise ilifu lamanqaku.
- Cokisa ilifu lencopho ukususa ingxolo namachaphaza angeyomfuneko.
- Yenza i-polygon mesh ukusuka kwilifu lendawo kwaye usebenzise ukuthungwa okusekwe kwiifoto zokuqala.
- thumela ngaphandle isiphumo kwifomathi ehambelanayo nezinye iinkqubo ezifana neRevit, AutoCAD okanye iBlender.
