A Photogrammetry example please? #30

Is it possible to get a photogrammetry sample project? Or at least some direction on how to get started?

Hi @Shubhra22. Apologies for the late reply.

Maybe we can help you better if we knew what your goal is.

Could you describe the photogrammetry task you are working on?
- For example, you could describe what the input is and what the desired output is.
What are you currently blocked on?
What subset of functionalities would be most helpful if they were implemented in a sample project?

Thanks for your input!

Hey @leapally It's my turn now to say sorry for the late reply.

Ideally, I am looking for the following workflow: User upload a set of images and gets out a textured mesh. If it's a too much of an ask, may be direct me what classes/ files I should look into to implement something myself.
I am currently using open3d api for this, but there is not any direct mobile device support from it. I understand the whole process of a reconstruction from a higher level, (from using API like open3d), so its little overwhelming to find which particular classes I should look into/ use to create a 3d reconstruction.
I would say if there was at least an example for Structure from Motion or may be a mesh reconstruction that might be very helpful.

Hey, @Shubhra22. Thanks for the reply.

I see that there is a Windows demo named "structurefrommotion" available. I believe the only way to build it is with the Visual Studio solution for Windows platform.

I'm not familiar with this particular demo, but I can ping the team tomorrow about it and see whether a structure from motion demo on mobile platforms is something that is doable.

Hey, @Shubhra22.

Conclusion from discussion was that we don't have bandwidth to create photogrammetry demos for mobile platforms at the moment. I'll see if I can find examples within existing code that might help aside from "structurefrommotion".
