Indlela yokutshala nokuhlanganisa izithombe

Lokhu kuphume njengomkhuba odingekayo esifundweni muva nje ngifundisile kusuka eMicrostation naseManifold, lapha ngiveza isifinyezo sendlela:

Nginesithombe esilandiwe kusuka kuGoogle Earth, engisikisele ngokwedlule futhi ngifuna ukusisusa ngokususelwa ku-polygon emelela ukunwetshwa komngcele wamadolobha wokuhlala kwabantu.  Ngemuva kwalokho ngifuna ukuyihlanganisa nesithombe esikala grey ukuthi nginesinqumo esisezingeni eliphansi kepha okuyisithombe esisodwa esigcina isithombe sombala ngaphambili.

Kulokhu ngizosebenzisa iMicrostation Descartes, elingana ne-AutoCAD Raster Design noma lokho esikwaziyo ngokuthi ukunqwabelanisa. Uma amathuluzi we-Descartes engabonakali, yenza "amathuluzi / amabhokisi wamathuluzi" futhi lapho kwenziwa khona iphaneli le- "Descartes Raster Control".

1. Sika isithombe ngokusezingeni le-polygon.

Uma senginayo i-polygon, ngisebenzisa umyalo "we-corridor izithombe", ingibuza i-polygon yokusika, ngakho ngiyayikhetha ngokuchofoza ukwakheka okuphuzi. 
Khona-ke uma wenza ukuchofoza kwesibili, isikrini sibonakala singibuza:

• Yisiphi isithombe senkomba engifuna ukusisika
• umzila wendawo
• ifomethi yesithombe
• Uma ngifuna ukubonakala ngokusobala ekusikeni okusikiwe
• nosayizi wokukhipha pixel. 

Ngokuzenzakalelayo ngibeka usayizi wamaphikseli isithombe esinawo kodwa ngingawashintsha.

Ngemuva kwalokho umyalezo uvela ekhoneni olicubungulayo, bese kuthi isithombe esiyisithenjwa sivele ekugcineni. Umphumela ungabona ukuthi isithombe sombala sinqunyiwe, konke okunye kusobala ukuze ngibone isithombe esimpunga ngemuva.

2. Hlanganisa zombili lezi zithombe

  Manje engikufunayo ukwenza esinye sezithombe zombili, ngakho-ke ngenza isimo sendawo engifuna ukuyihlanganisa, bese ngisebenzisa inkinobho "yokuhlanganisa izithombe". Ingibuza ngokufana nomyalo odlule, nomehluko wokuthi kulokhu angikhombisi isithombe ngasinye kepha kunalokho inketho ethi "average" ukukhetha zombili.

Futhi manenekazi aselungile, nibone ukuthi muhle kanjani, enze isithombe nobabili.

Ah, ukwenza lokhu, akudingeki ukuthi ube nelayisense le-Descartes noma le-Microstation, ngoba i-disc esetshenziswa yi-Bentley uma ufaka ikhasi layo ekhethweni le-Select CD kukunika imizuzu eyi-15 ... engikwenzile kungibize 11.
