I have a 360° camera capable of shooting both images and video.
I would like to use it to build 3d model of the interior of a room.
To do this, I need multiple images of the room from multiple points of view.

I was thinking about a script which makes what follows, but don't know which tool to use to perform the needed projection:
- downsample the video from 25FPS to 5 FPS or 1 FPS
- extract from each spherical frame some "planar subframes" (12? 24? how many?), showing only a small area of the sphere (i.e. almost undistorted, or "planar")
- group the subframes in 4 groups, one per each wall of the room.

Once I've done this, it's just a matter of feeding Autodesk Remake (or similar SW) to get a 3d model of each wall.

I think I can do the first step by using Virtualdub capability of downsampling videos, but how to perform second step?

I googled these tools, which one could be suitable? I'm on Windows 10.

D3-Geo looks very powerful, but quite hard to understand.

I can code in VBA and Javascript; I don't want to install and manage heavy C/C++ SDKs.

The third step is easy, it's just a matter of grouping the images by heading of the subframe.
