Momwe mungakolole ndikuphatikiza mafano

Izi zinatuluka ngati zofunikira mu maphunziro posachedwapa zomwe ndapereka wa Microstation ndi Yowonekera, apa pali chidule cha momwe:

Ndili ndi chithunzi Google Earth pansi, ine ndikufuna kudula georeferenciado ndi zochokera polygon woimira kutambasuka kwa wozungulira m'tauni ya kuthetsa anthu.  Ndiye ndikufuna kuti ndiphatikize ndi chithunzi chachikulu chomwe ndili nacho chokhazikika koma ndizojambula chimodzimodzi ndikusunga mitundu kutsogolo.

Poterepa ndidzagwiritsa ntchito Microstation Descartes, yomwe ndi yofanana ndi AutoCAD Raster Design kapena zomwe timadziwa kuti Overlay. Ngati zida za Descartes sizikuwoneka, pangani "zida / mabokosi azida" ndipo pamenepo pali gulu la "Descartes Raster Control".

1. Dulani chithunzichi pogwiritsa ntchito polygon.

Kamodzi ndikakhala ndi pulogoni, ndimagwiritsa ntchito lamulo lakuti "zithunzi zowonongeka", limapempha pulogoni yodula, kotero ndikusankha iyo podalira mawonekedwe achikasu. 
Ndiye pamene mukupanga kachiwiri, chinsalu chimapezeka ndikufunsa:

• yomwe ndi zithunzi zomwe ndikufuna kuzidula
• njira yopita
• mawonekedwe a zithunzi
• Ngati ndikufuna kutuluka mwachisawawa m'magawo otsala
• ndi kukula kwa pixel kukula. 

Mwachindunji ndikuyika kukula kwa ma pixel amene fano ili nalo koma ndikusintha.

Kenako uthengawo ukuwoneka pakona yomwe mukukonza, ndipo chithunzi chake chikuwonekera kumapeto. Zotsatira zake mutha kuwona kuti chithunzi chautoto chidadulidwa, china chowonekera poyera kuti nditha kuwona chithunzi chakhungu kumbuyo.

2. Gwirizanitsani zithunzi zonsezo

  Tsopano zomwe ndikufuna ndikupanga imodzi mwazithunzi zonsezi, chifukwa chake ndimapanga dera lomwe ndikufuna kuphatikizana, ndikugwiritsa ntchito batani la "kuphatikiza zithunzi". Zimandifunsa chimodzimodzi ndi lamulo lapitalo, ndi kusiyana komwe pakali pano sindikuwonetsa aliyense wa mafano koma makamaka "mwayi" kusankha kusankha zonse.

Ndipo, amayi ndi alongo, onani momwe izo ziliri zodabwitsa, izo zapanga fano ndi zonse.

Ah, kuti muchite izi, simukusowa kukhala ndi laisensi kuchokera ku Descartes kapena Microstation, chifukwa diski yotumizidwa ndi Bentley ngati mutalowa tsamba lanu mu chisankho cha CD mumakupatsani maminiti 15 ... zomwe ndachita zanditengera ine 11.
