Pangani chitsanzo cha digito (MDT / DTM) ndi Microstation ndipo muyenerere ma orthophoto

Poyamba tinali kuona momwe MDT yakhalira, ndi mikangano ndi AutoCAD kuti apange mizere yozungulira.

Pulogalamu yabwino yochitira izi ndi GeoPack, yochokera ku Microstation yomwe ili yofanana ndi Civil3D kuchokera ku AutoDesk, itha kuchitidwanso ndi Descartes, yofanana ndi AutoCAD Raster Design. Ndi mapulogalamuwa mulu wa njira umasungidwa koma mu nkhani iyi tidzatero kokha ndi Microstation V8.

1. Fayilo yoyambira

Tidzagwiritsa ntchito fayilo yomwe ili kale ndi mesh ya mfundo mu miyeso itatu, yotchedwa 220_Points.dgn, tinali tanenapo za momwe mungathere mphete ya xyz mfundo kuchokera ku bokosi Kuchokera ku Microstation. Ife tikuyenda ndi kutsegula «Mfundo » monga yogwira ntchito.

2. Kupanga chitsanzo cha mtunda

  • Tapanga chatsopano chatsopano chotchedwa DTM
  • Sankhani mtundu ndi mtundu wa mzere
  • Timachita msinkhu woyenerera
  • Timasankha mfundo zonse ndikuyimira pakalata yopangira malemba (Zofunikira / zofunikira) «mdl load facet;«Popanda ndemanga
  • Kenaka mubokosi lotsatira timasankha tab Zambiri za XY ndipo yambitsani "Lonjezani ku Rectangle », kuti tilembe khomo kumene tikufuna kuti dongosolo liwonongeke
  • Tsopano ife tikukanikiza batani «Triangulate XY Mfundo »

chithunzi

  • Njira ina ndikugwiritsira ntchito kuphatikiza kwa makina awa: mdl load facet;. Izi zidzatulutsa zotsatira zomwezo, kuthetseratu zofunikira kuti mutsegule zokambirana. N'zachidziwikire kuti ichi cholowera makina chidzagwiritsira ntchito chikhalidwe chamakono (pa / chotsala) cha bokosi «Lonjezani ku Rectangle ».
  • Panthawi ya m'badwo, MicroStation idzatsegulewindo laling'onoting'ono lazithunzithunzi ndikuwonetsera zitatu zomwe zatsogozedwa ndi makalata otsatirawa:
    V - Chiwerengero cha zowonongeka pambaliyi.
    F - Chiwerengero cha nkhope kapena katatu m'zimene zimayambitsa.
    C - Chiwerengero cha zowonjezera zomwe zimagwiritsidwa ntchito. Chifukwa cha katatu, phindu limeneli liyenera kukhala 1.

3. Kukonzekera Kuwala Kulipira

Tidzakonza mapepala, tisanati tiike orthophoto.
Kuti tipeze kusintha kotere kwachitsanzo, tidzasintha chiwonetsero chonse.

  • Timasankha «Zida / Kuwonetsera / Kupereka / Kuunikira Kwambiri » ndipo mu bokosi lazokambiranalo timasintha makhalidwe kuti agwirizane ndi grafu yotsatirayi.
  • Kuti mupange pamwamba, kuchokera ku bokosi lomwelo, chotsani chida «Perekani » ndi kusintha ndondomeko izi motere:
    Cholinga = View, Njira = Smooth, ndi Shading Type = Normal.
    Lowetsani mfundo muyeso yeniyeni ndikuyamikira zotsatira zanu.

4 Kutsegula chithunzi cha raster ku microstation

  • Kuchokera ku Raster Manager (Raster Manager), sankhani «Foni / Yandikirani » ndi kusankha «220_Image.jpg ». Chithunzichi ndi georeferenced, kotero timatsimikiza kuti titsetse «Malo Osasunthika » kuchokera ku "kulumikiza" bokosi la bokosi.

Timapeza deta zotsatirazi za katundu wa fanolo:

  • Timabwerera ku zolemba za Raster Manager (Raster Manager). Ife navigate kuti «Malo » ndipo onani data zotsatirazi:
  • miyeso - Uku ndi kukula kwa chifaniziro chomwe chithunzicho chili, 5,286 mamita lonse ndi 5,228 mamita okwera.
  • Kukula kwa Pixel (Kukula kwa Pixel) - Uku ndi kukula kwa pixel, mu zigawo zazikulu. Chithunzi chathu chili ndi kukula kwa pixel ya mamita a 1.
  • Origin (Chitsime) - Iyi ndi malo a XY kumbali ya kumanzere ya chithunzi. Kotero ngodya ya kumanzere ya kumbuyo kwa chithunziyo imalowa mkati XY = 378864.5, 5993712.5

5. Kupanga zinthu pogwiritsa ntchito kujambula kwazithunzi (Ortofoto)

Njira yopanga zipangizo ndi yakale mu Microstation, monga chitsanzo kupanga zooneka bwino; Pachifukwa ichi tidzakagwiritsa ntchito kuti tiwoneke ngati zinthu zomwe timagwiritsa ntchito pozipereka ndi orthophoto monga mafano ena mwa mawonekedwe apamwamba.

  • Kuchokera ku bokosi lazamasamba «Kupereka Zida », timasankha «Kufotokozera Zida ».
  • Pamene mutha kukamba nkhaniyi nthawi yoyamba, MicroStation idzafika kumbali yakumanzere ndi kulowa komwe kuli kofanana ndi dzina la fayilo. Kulowera ndiko kuyamba kwa tebulo zakuthupi (tebulo lamlengalenga) yomwe ndi fayilo yokhala ndiwonjezera .mat. Gome lamakono limasungira zinthu zakuthupi ku zinthu zomwe zili mu fayilo yomwe ili pazithunzi zina komanso ili ndi mtundu wina.
  • Kuchokera ku menyu ya menyu, timasankha «Palette> Chatsopano »
    MicroStation ikuyankha mwa kuwonjezera "Palette Yatsopano (1) » pansi pa tebulo la zipangizo.
  • Timatcha dzina ili ngati «PhotoDrape » kusankha «Palete / Sungani Monga », kapena polemba molondola pa cholowera ndikusankha 'Sungani monga pa mndandanda.
    Pochita izi, MicroStation imapanga fayilo yotsegula, yomwe ili ndizowonjezereka .pal.
     

  • Kupanga zinthu zomwe timayambitsa batani "Nkhani Zatsopano » ndipo timatchula " Zida Zatsopano (1) » monga «Ndege«
  • Kuti mupange chithunzi cha mlengalenga ngati chinthu, dinani pachithunzi chaching'ono chomwe chili pamunsimu ndikusankha «120_Image.jpg ».
  •  

     

chithunzi

  • Tsopano tikugwiritsa ntchito deta yomwe tapeza kale ku fano:
  • "Mapu" ku «Mzere wamakono »
    X kukula = 5286 ndi Y Size = 5228
    Kuperekera X = 378864.5 ndi Kutayika Y = 5998940.5
  • Timatseketsa "ndondomeko" ndikukambirana zosintha ndi kukakamiza «Sungani » mu bokosi la dialog "Material Editor".

6. Kujambula zithunzi zojambula zithunzi (orthophoto) kupita ku DTM monga momwe amachitira

     

  • Timatsegula bokosi la dialog "Material Editor" ndikusankha "Ikani Zambiri Zamkatimu » kuchokera ku bokosi lazamasamba «Kupatsa Zida ».
  • Tinafufuza kuti tipeze cholembera choyenera ndi zinthu zosankhidwa monga momwe tawonetsera pa ndondomeko yotsatirayi.
  •  

  • Timayesetsa «Perekani ndi Mzere / Mtundu » ndipo sankhani mesh element yomwe ikuimira malo.
  • Kuchokera ku bokosi lazamasamba «Chida Chothandizira », timasankha chida «Perekani » ndi kusintha ndondomeko izi motere:
    Cholinga = View, Njira = Smooth, ndi Shading Type = Normal.
  • Tsopano ife tikuyang'ana malingaliro owonetsera ndipo ndizo.

Potsatila izi tinagwiritsira ntchito ndondomeko yomwe Jorge Ramis analemba pa tsamba lakale la Geocities lomwe liyenera kupulumutsidwa chifukwa tsiku lina Yahoo izi zimawononga ntchito iyi, izi zasinthidwa kuchokera Askinga.

Mabaibulo atsopano a Microstation ali ndi ntchito kuti muchite izi zithunzi za Google Earth komanso Bentley ntchito ndizochita zenizeni chifukwa chogwiritsira ntchito zitsanzo zamakono.

7 Imayankha "Pangani mtundu wamagetsi wapa digito (DTM / DTM) wokhala ndi Microstation ndikukhala ndi orthophoto"

  1. Maphunziro abwino kwambiri, ndikupeza funso, kodi mungathe kuchita zomwezo? ndiko kuti, kuchokera kumtunda wautatu angapangidwe ma curve?

    Sungani ndi kuyamika

  2. ZINA ZIMENE ZILI ZOFUNIKA KWAMBIRI KUWERENGA MDT NDI MICROSTATION V8 ZOTHANDIZA MAVIDIYO MILAN MARTINEZ

  3. Zikondwerero zokondweretsa kwambiri koma ndimangogwira ntchito zokhudzana ndi ntchito komanso microstation ine ndikufuna kupanga MDT URGENT NDIDITHANDIZE

  4. Chonde ndithandizeni kuchita NDI MicroStation MDT MWAMSANGA ndipo ine ESTODIANDO timafunika thandizo kwa mnzanu kapena kampani kwambiri AGRACEDERE moni Milan La Paz Martínez Martínez-BOLIVIA
