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 yiGeoPack, evela kwiMicrostation elingana ne-Civil3D evela kwi-AutoDesk, inokwenziwa nakwiDescartes, elingana ne-AutoCAD Raster Design. Ngezi nkqubo isitokhwe samanyathelo sigcinwa kodwa kule meko siza kuthi 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. Sikhangela kwaye sivula "Amanqaku” njengomzekelo osebenzayo.

2 Ukudala imodeli yomhlaba

  • Sakha inqanaba elitsha (uluhlu) olubizwa ngokuthi iDTM
  • Sakhetha umbala kunye nohlobo lomgca
  • Senza inqanaba elisebenzayo
  • Sikhetha onke amanqaku kwaye uchwetheze kwibar yomyalelo wokubhaliweyo (izinto eziluncedo / isitshixo-ngaphakathi) "umxholo we-mdl; incoko yencoko", ngaphandle kweengcaphuno
  • Emva koko kwisakhelo esilandelayo sikhetha ithebhu XY Amaphupha kwaye uvule"Yandisa kuxande”, ukuphawula ucingo apho sifuna khona inkqubo ukuba ihlalutye imodeli yomhlaba
  • Ngoku sicofa iqhosha "NONE

umfanekiso

  • Enye indlela yokusebenzisa le nxalenye yokufakelwa kwebhobhodi: umthwalo we-mdl umthwalo; i-facet triangulate xypoints. Oku kuya kuvelisa iziphumo ezifanayo, ukususa imfuneko yokuvula iibhokisi zencoko yababini. Kucacile ukuba olungeno lwebhodi yezitshixo luzakusebenzisa imeko yangoku (on/off) ye “Yandisa kuxande”.
  • Ngethuba lenkqubo yokuvelisa, i-MicroStation iya kuvula iwindow encinci yecatshulwa kwaye ibonise iintlawulo ezintathu ezilandelelwe yileta zilandelayo:
    V -Inani lama-vertices kwinto ebangelwayo.
    F - Inani lobuso okanye oonxantathu kwinto ebonakalayo.
    C -Inani lezinto zemveliso ezixhumeneyo. Kwinkqubo yoxantathu, eli xabiso kufuneka lihlale libe-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 / Umboniso / Unikezelo / Ukukhanya kweHlabathi ” kwaye kwibhokisi yencoko yebhokisi yebhokisi yebhokisi yebhokisi yencoko ihlaziya ixabiso ukuze bavumelane negrafu elandelayo.
  • Ukunikezela umphezulu, kwibhokisi yesixhobo enye, khetha "NONE 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

  • KuMphathi weRaster, khetha "Ifayile / Qhoboshela" kwaye ukhethe "220_Image.jpg”. Lo mfanekiso une-georeferenced, ke qiniseka ukuba awukhangeli "Indawo Ngokusebenzisanayo” yebhokisi yencoko "yekhonkco".

Sifumana idatha elandelayo yeepropati zomfanekiso:

  • Sibuyela kwiisetingi zereferensi ngoMlawuli weRaster. Sijonge kwithebhu "Indawo” kwaye sibhala idatha elandelayo:
  • amacala Lo ngungakanani ubukhulu bomfanekiso, 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 "RenderingTools”, sikhetha"Chaza iMathiriyeli”.
  • 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.
  • Kwibar yemenyu, khetha "Iphalethi > Entsha”
    I-MicroStation iphendula ngokongeza "IPalethi Entsha (1)” phantsi kwetafile.
  • Siyibiza ngokutsha le nto ngokuthi "IfotoDrape” ukhetha "Iphalethi / Gcina njenge ", okanye ngokuchofoza ngakwesokudla ekungeneni kwaye ukhetha 'Gcina nje ' kuluhlu.
    Ngokwenza oku, i-MicroStation idala ifayile yepalette, eneendandiso .pal.
     

  • Ukwenza imathiriyeli sivula iqhosha "Izinto ezintsha” kwaye siqamba igama kwakhona " Izinto Ezintsha (1)” njengo "lwasemoyeni"
  • Ukwabela ifoto yasemoyeni njengento ebambekayo, cofa kwi icon encinci eboniswe kumzobo ongezantsi kwaye ukhethe "120_Image.jpg”.
  •  

     

umfanekiso

  • Ngoku sisebenzisa idatha esiyifumene ngaphambili kwimifanekiso:
  • "Imaphu" "uUkuphakama kwedrape"
    X Size = 5286 kwaye No Size = 5228
    Ukusetyenzwa X = 378864.5 kwaye Ukucinywa kweY = 5998940.5
  • Sivala incoko "yepatheni" kwaye sigcine utshintsho ngokucinezela "Gcina ” kwibhokisi yencoko ethi "Umhleli weMaterial".

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

     

  • Sivala ibhokisi yencoko ethi "Umhleli weMaterial" kwaye ukhethe "Sebenzisa izinto eziphathekayo” kwibhokisi yezixhobo”Izixhobo zoBonelelo”.
  • Siyaqinisekisa ukuba sinayo ipalali echanekileyo kunye nezinto ezikhethiweyo njengoko kuboniswe kumzobo olandelayo.
  •  

  • Cinezela "Yabela ngokweNqanaba/ngoMbala” kwaye sikhetha i-elementesh shayi emele indawo.
  • Kwibhokisi yezixhobo "Isixhobo sokuBonelela”, sikhetha isixhobo "NONE 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.
