Ita digital model model (MDT / DTM) ne Microstation uye yakagadzirira anthophoto

Pakupedzisira taive tichiona kuti MDT yakagadzirwa sei, uye mitsara yakasiyana-siyana uye AutoCAD kuti kuve nematombo emazinga.

Chirongwa chakanak kuita izvi GeoPack, kubva kuMicrostation, inova yakaenzana neCivil3D kubva kuAutoDesk, inogona zvakare kuitwa neDescartes, yakaenzana neAutoCAD Raster Dhizaini. Nemapurogiramu aya mudungwe wematanho unochengetwa asi mune ino kesi ticha chete ne Microstation V8.

1. Iyo sosi faira

Tichashandisa faira iyo inenge iine mesh yepikisi muzviyero zvitatu, zvinodanwa 220_Points.dgn, tanga tataura pamusoro pekuti ungagona sei kutumira mesh ye xyz pfungwa kubva mubhokisi Excel to Microstation. Tinofamba nekuvhura"Mapoinzi” semuenzaniso unoshanda.

2 Generating model land

• Isu tinoumba hutsva hutsva (humwe) hunonzi DTM
• Tinosarudza mararamiro uye rudzi rwemutsara
• Isu tinozviita iyo inoshanda yepamusoro
• Isu tinosarudza ese mapoinzi uye tonyora mune zvinyorwa zvekuraira bar (zvishandiso / kiyi-mukati) "mdl load facet; nhaurirano hurukuro", pasina zvirevo
• Zvadaro mubato rinotevera tinosarudza tab XY Points uye activate"Wedzera kuita Rectangle”, kuisa fence kune kwatinoda kuti hurongwa huratidze humiriri hwemuvhu

• Iye zvino tinodzvanya bhatani "Triangle XY Mapoinzi”

• Imwe nzira ndeyekushandisa kusanganiswa kweiyo keyboard: mdl load facet; chimiro chetatu chinonzi xypoints. Izvi zvinoburitsa mhedzisiro imwe chete, kubvisa chinodiwa kuti uvhure dialog mabhokisi. Zviripachena kuti iyi keyboard yekupinda ichashandisa yazvino mamiriro (on/off) ye“Wedzera kuita Rectangle”.
• Munguva yerudzi rwekuita, MicroStation ichazarurawo mahwindo maduku ekutumira uye kuratidzira zvitatu zvinotangira mavara anotevera:
  V -Uwandu hwema vertices mune chinokonzeresa chinhu.
  F -Uwandu hwezviso kana makona matatu mune zvinokonzeresa chinhu.
  C - Nhamba yezvakabatana inoburitsa mesh zvinhu. Nezvekutapudza maitiro, kukosha uku kunofanira kugara kuri 1.

3 Kugadzira Lighting kuti ipe

Tichazopa nzvimbo yacho, tisati tasarudza orthophoto.
Kuti tive nekushandura zviri nani kwemuenzaniso uyu, tichazotanga kugadzirisa kujekesa kwenyika yose.

• Tinosarudza"Zvishandiso / Kuona / Kupa / Kupenya Kwepasirese” uye mumugumisiro webhokisi rebhokisi tinoshandura mararamiro kuitira kuti vabvumirane nerafu inotevera.

• Kupa pamusoro, kubva mubhokisi rematurusi rimwe chete, sarudza iyo "Render” uye uchinje maitiro sezvinotevera:
  Target = maonero, Ipai Mode = Smooth, uye Shading Type = Normal.
  Pinda pfungwa yedhesi muono yeometri uye unyeke migumisiro yayo.

4 Kunyorera raster image kuva microstation

• Kubva kuRaster Maneja, sarudza "Faira / Batanidza" uye sarudza "220_Image.jpg”. Mufananidzo uyu une georeferenced, saka ita shuwa kuti hautarise "Nzvimbo Inopindirana” ye "link" dialog box.

Tinowana data inotevera yezvinhu zvechifananidzo:

• Isu tinodzokera kune mareferenzi marongero kuburikidza neRaster Maneja. Isu tinoenda kune iyo tab "Nzvimbo” uye tinonyora data inotevera:
• miganhu - Uku ndiko kufukidza ukuru hwemufananidzo, 5,286 mamita yakafara uye 5,228 mamita mamita
• Pixel Size (Pixel size) - Ichi ndicho chiyero chechipiri, mune zvidzidzo. Chimiro chedu chine ukuru hwepikseli wemamita 1.
• mavambo (Chitubu) - Iyi ndiyo nzvimbo XY yekona yezasi yakasara yechifananidzo. Saka kona yakasiyiwa yakasara yechifananidzo ichiiswa mukati XY = 378864.5, 5993712.5

5. Kuumba zvinhu zvakabva pane aerial photography (Orthophoto)

Nzira yekusika zvinhu yakwegura mu Microstation, semuenzaniso wekuita pachena; munyaya iyi tinozoishandisa kuti tiite sezviri kutaurwa isu zvatinoshandisa kupa iyo mifananidzo kana semamwe mifananidzo nenzira yekiyi inoshandiswa.

• Kubva mubhokisi rekushandisa "RenderingTools”, tinosarudza"Define Materials”.
• Apo iwe unopindira iyi ingano yekutanga, MicroStation ichazadza rutivi rworuboshwe nemuvharo wakaenzana nezita refaira. Izvi zvinotanga kutanga kwe tafura yezvinhu (tafura yekudenga) iyo iyo faira ine kuwedzera .mat. Tafura yezvokudya inochengetedza mahofisi ezvinyorwa kune zvikamu mune faira iri pamatanho chaiwo uye inewo maruva chaiwo.

• Kubva pane menyu bar, sarudza "Palette > Nyowani”
  MicroStation inopindura nekuwedzera "Palette Itsva (1)” pasi petafura yezvinhu.
• Isu tinopa izvi zvakare se "PhotoDrape” kusarudza"Palette / Chengetedza Se ", kana nechokuita nechokuita nepachokuita uye kusarudza 'Save As ' kubva pakurongwa.
  Nokuita izvi, MicroStation inogadzira faira yepalette, iyo inowedzera .pal.

 
• Kugadzira chinhu isu tinomisa bhatani "Zvinhu zvitsva” uye tinopa zita" Zvinhu Zvitsva (1)” se "zvemuchadenga"
• Kugovera iyo foto yemuchadenga sechinhu, tinya pane diki icon yakanamirwa mumufananidzo uri pazasi uye sarudza "120_Image.jpg”.

 

 

• Iye zvino tinoshandisa dhenda yatakambowana kubva pamufananidzo:
• "Mapping" a "elevation drape
  X Size = 5286 uye Uye Kukura = 5228
  Offset X = 378864.5 uye Offset Y = 5998940.5

• Isu tinovhara iyo "pattern" dialog uye chengetedza shanduko nekudzvanya "Sevha” mu "Material Edhiyo" dialog box.

6. Kugadzirisa Aerial Photography (orthophoto) kuenda kuDTM sezvinopa

 
• Isu tinovhara iyo "Material Editor" dialog box uye sarudza "Shandisa Zvinhu” kubva mubhokisi rematurusi”Zvishandiso Zvekupa”.
• Tinovimbisa kuti tine peeleti yakarurama uye zvinhu zvakasarudzwa sezvinoratidzwa mumifananidzo inotevera.

 

• Tinodzvanya "Govera Nenhanho/Ruvara” uye isu tinosarudza mesh chimiro chinomiririra nzvimbo.
• Kubva mubhokisi rekushandisa "Chishandiso Chekupa”, tinosarudza chishandiso "Render” uye tinogadzirisa maitiro sezvinotevera:
  Target = maonero, Ipai Mode = Smooth, uye Shading Type = Normal.
• Iye zvino tinoshandisa maonero ekusimudzira uye iwe wapedza.

Nokuti this post taishandisa nzira rwakaratidzwa Jorge Ramis muna Geocities peji yekare namaturo wokununura nekuti rimwe mazuva ano basa iri Yahoo anonyangarika, ichi rakashandurirwa kubva Askinga.

Zvose zvemazuva ano zveSyststation zvine maitiro kuita izvi ne Google Earth mifananidzo uyewo Bentley ane zvinoshandiswa nechinangwa chaicho nokuda kwekutungamirirwa kwemajiramu emigodhi.
