Hi,  
I want to build an orthophoto with drone images of a slope (cliffs), is it possible to make projection on a vertical plane?  
Thanks.

Thanks for your answer.  
I’m running ODM through Docker, how can I change the plane of projection? by default is built on an overhead plane.

@ITWarrior, I don’t think that’s what was meant, but as always it’s great to see the projects you are up to.

@Mar, there is no trivial way (at the moment) to do what you want, but you could get something pretty close by loading the textured mesh into [meshlab](https://meshlab.org), finding the perspective you want, `Toggle Orthographic Camera` (under the `View` menu) and then `File:Save Snapshot` to create an image from it.

_Caveats_ – you have limited control of resolution and it won’t have a coordinate system, but it will be a proper off-[nadir](https://en.wikipedia.org/wiki/Nadir) orthophoto.

Alternatively, a modification starting with [https://github.com/OpenDroneMap/ODM/blob/master/modules/odm\_orthophoto/src/OdmOrthoPhoto.cpp](https://github.com/OpenDroneMap/ODM/blob/master/modules/odm_orthophoto/src/OdmOrthoPhoto.cpp) would be the more robust approach. I’ve long dreamed of being able to do this… .

One more possible approach would be to do this in [Blender](https://www.blender.org/), using some adapted version of [these scripts](https://github.com/OpenDroneMap/ODM/tree/master/contrib/blender).

Hi,  
Still no answer ? As Mar, I want to build an orthophotomosaic with drone images of a vertical slope (cliffs). I use the end user version webODM.  
Thanks
