I have pair of images: can I generate digital elevation model from that pair of images using QGIS? if it's possible, can anyone provide the way to do that?

There is a tool in the Orfeo-Toolbox called stereo framework. It might do what you want, and can be integrated into Qgis.


But you can´t get a elevation model out of normal images. It will be at most a terrain model as you are only seeing the surface of the trees, buildings and so on.

  • thank you for your response i have cartosat stereo images of a place with those i want to create a DEM of that place. is there any direct plugins or functions atleast read those images bcoz i am new to this software

I never try to create dem from stereo image pair but searching on web I found this post very interesting: https://www.orfeo-toolbox.org/elevation-maps-from-along-track-stereo-pairs/ You can use orfeo tools in qgis after setting it. Look this QGSI documentation: https://docs.qgis.org/2.2/en/docs/user_manual/processing/3rdParty.html

  • Thank you ,from many discussions i found that orfeo toolbox is tough and micmac tool also so is there any GUI based automatic DEM extraction from stereo images
