Yenza imodeli yomhlaba wedijithali (MDT / DTM) nge-Microstation kwaye ulungele i-orthophoto

Ngaphambili sasibona indlela i-MDT eyenziwe ngayo, kunye nemigca yokujika nge-AutoCAD ukuvelisa iirveve zamanqanaba.

Inkqubo efanelekileyo yokwenza oku yiGePack, ukusuka kwi-Microstation efana ne-AutoXX ye-Civil3D, inokuthi yenziwe nge-Descartes, elilingana ne-AutoCAD Raster Desing. Ngale nkqubo ugcina ulandelelwano lwamanyathelo kodwa kule meko siyakwenza kuphela nge-Microstation V8.

1. Ifayile yomthombo

Siza kusetyenziswa ifayile esele ine-mesh of points in three dimensions, ebizwa 220_Points.dgn, siye sathetha ngaphambili malunga nendlela ongayifaka ngayo imitha yee-xyz amaphupha avela kwibhokisi Excel ukuya kwi-Microstation. Sihambahamba kwaye sivula «Amanqaku » njengomzekelo osebenzayo.

2 Ukudala imodeli yomhlaba

  • Sakha inqanaba elitsha (uluhlu) olubizwa ngokuthi iDTM
  • Sakhetha umbala kunye nohlobo lomgca
  • Senza inqanaba elisebenzayo
  • Khetha onke amanqaku kwaye uchwetheze bar bar yokuyalela (izixhobo / isitshixo)umxholo we-mdl; incoko yencoko«Ngaphandle kwezicatshulwa
  • Emva koko kwisakhelo esilandelayo sikhetha ithebhu XY Amaphupha kwaye usebenze «Yandisa uxande, ukuphawula ucingo apho sifuna khona inkqubo ukuba ihlalutye imodeli yomhlaba
  • Ngoku sicinezela «Nikezela Iingcebiso zeXY »

umfanekiso

  • Enye indlela yokusebenzisa le nxalenye yokufakelwa kwebhobhodi: umthwalo we-mdl umthwalo; i-facet triangulate xypoints. Oku kuya kuvelisa iziphumo ezifanayo, kuphelisa imfuneko yokuvula ibhokisi yencoko yababini. Kucacile ukuba oku kungenela ikhibhodi kuzakusebenzisa imeko yangoku (kwi / off) ye «Yandisa uxande.
  • Ngethuba lenkqubo yokuvelisa, i-MicroStation iya kuvula iwindow encinci yecatshulwa kwaye ibonise iintlawulo ezintathu ezilandelelwe yileta zilandelayo:
    V - Inombolo yezilwanyana kwisiphumo esiphumela.
    F - Inombolo yobuso okanye i-triangles kwisici esiphumelayo.
    C - Inani lezinto ezixhunyiwe ezixubileyo. Inkqubo yoxathulo, le xabiso kufuneka ihlale i-1.

3. Ukuqwalasela ukuKhanya ukunikezela

Siza kunika indawo, ngaphambi kokufakela i-orthophoto.
Ukuze ufumane ukulungiswa okungcono kwalo mzekelo, siya kulungelelanisa ukukhanya kwehlabathi kuqala.

  • Sikhetha «Izixhobo / Ukujonga ukubona / ukuhambisa / ukuKhanyisa kwiLizwe » kwaye kwibhokisi yencoko yebhokisi yebhokisi yebhokisi yebhokisi yencoko ihlaziya ixabiso ukuze bavumelane negrafu elandelayo.
  • Ukunikezela umphezulu, kwibhokisi yesixhobo efanayo, khetha isixhobo «Render » kwaye uhlengahlengise ixabiso njengalandelayo:
    Ithagethi = View, Inkqubo yeRender = Smooth, kunye neShading Type = eqhelekileyo.
    Faka ingongoma yedatha kwimbonakalo ye-isometric kwaye uzuze iziphumo zayo.

4. Ukulayisha umfanekiso we-raster kwi-microstation

  • Ukusuka kuMphathi weRaster, khetha «Ifayile / Fakela uze ukhethe «I-220_Image.jpg ». Lo mfanekiso ubhekiswe kwi-georefere, ngoko ke siyaqinisekisa ukwenza i-deactiv «Beka ngasekhaya ukusuka kwi "link" ibhokisi yencoko yababini.

Sifumana idatha elandelayo yeepropati zomfanekiso:

  • Sibuyela kulungiselelo lwesethenjwa kuMphathi weRaster. Sihamba siye e «Indawo » kwaye sibhala idatha elandelayo:
  • amacala - Olu bubungakanani bobugcisa obunomfanekiso, 5,286 ububanzi bomitha kunye 5,228 eziphezulu kumitha
  • Usayizi wePixel (Ubungakanani bePixel) - Olu bubungakanani be-pixe, kwiiyunithi eziphambili. Umfanekiso wethu unobungakanani bepikseli yeemitha ze-1.
  • imvelaphi (Umthombo) - Le yindawo ye-XY yekona elingezantsi lasekhohlo lomfanekiso. Ngoko ikhoneni elingezansi lasekhohlo lomfanekiso lifakwe kuyo XY = 378864.5, 5993712.5

5. Ukudala izinto ezisekelwe kwimifanekiso yezithuthi (Orthophoto)

Isicwangciso sokudala izinto zidala kwi-Microstation, njengomzekelo ukwenza i-transparencies; Kule meko siza kuyisebenzisa ukwenzela ukuba ibonakale njengento esiza kuyisebenzisa ukunikezela i-orthophoto njengeminye imifanekiso ngendlela yokhiye.

  • Kwibhokisi yezixhobo «Izixhobo Zokuhambisa », sikhetha «Chaza izixhobo ».
  • Xa ufinyelela le ngxoxo okokuqala ngqa, i-MicroStation iya kufaka icala langasobunxele ngendawo yokungena efana nefayile yefayile. Oku kungena kukuqala kwe itafile (itafile) leyo ifayile kunye nokwandiswa .mat. Itheyibhile yezinto eziphathekayo igcina izabelo zezinto eziphathekayo kwizinto kwifayile ezisezingeni elithile kunye nombala othile.
  • Kwibhari yemenyu, sikhetha «I-Palette> Ntsha »
    I-MicroStation iphendula ngokongeza «I-Palette entsha (1) » phantsi kwetafile.
  • Esi sibizwa ngokuba yi- «PhotoDrape » Ukukhetha «I-Palette / Gcina njengo », okanye ngokuchofoza ngakwesokudla ekungeneni kwaye ukhetha 'Gcina nje ' kuluhlu.
    Ngokwenza oku, i-MicroStation idala ifayile yepalette, eneendandiso .pal.

  • Ukudala isixhobo esishukumisayo «Isixhobo esitsha » Kwaye sibiza igama elitsha » Izinto ezintsha (1) » njenge «lwasemoyeni«
  • Ukwabela ifoto ye-aerial njengemathiriyeli, cofa kwi icon encinci eboniswe kwigrafu engezantsi kwaye ukhethe «I-120_Image.jpg ».

umfanekiso

  • Ngoku sisebenzisa idatha esiyifumene ngaphambili kwimifanekiso:
  • «Imephu» ukuya «Ukuphakama kwidrowa »
    X Size = 5286 kwaye No Size = 5228
    Ukusetyenzwa X = 378864.5 kwaye Ukucinywa kweY = 5998940.5
  • Sivalela "iphethini" incoko yababini kwaye sigcina utshintsho ngokucinezela "Gcina » Kwibhokisi yencoko yababini "Wemhleli Wempahla".

6. Ukuhlala kwi-Aerial Photography (orthophoto) ukuya kwi-DTM njengoko unikezelayo

  • Sivalela ibhokisi yencoko yababini "yoMhleli wezinto" kwaye ukhethe «Faka izixhobo yebhokisi yezixhobo «Izixhobo Zokuhambisa ».
  • Siyaqinisekisa ukuba sinayo ipalali echanekileyo kunye nezinto ezikhethiweyo njengoko kuboniswe kumzobo olandelayo.
  • Cinezela «Yabela inqanaba / umbala » kwaye sikhetha i-elementesh shayi emele indawo.
  • Kwibhokisi yezixhobo «Isixhobo sokuhambisa », khetha isixhobo «Render » kwaye silungisa ixabiso njengalandelayo:
    Ithagethi = View, Inkqubo yeRender = Smooth, kunye neShading Type = eqhelekileyo.
  • Ngoku sisebenzela umbono we-isometric kwaye uyenziwe.

Kule thumela sisebenzise inkqubo eboniswe nguJorge Ramis kwiphepha elidala leGeocities elifanelekile ukuhlangula ngoba olunye usuku lwale Yahoo luyabonakala le nkonzo, oku kuguqulelwe ukususela Askinga.

Iinguqulelo zakutshanje ze-Microstation zisebenza ukwenza oku Imifanekiso yeGoogle Earth kunye neBentley inayo izicelo ezinokwenza ezithile ukulawulwa kweemodeli zendawo yedijithali.
