Description
There should be a reconstruction initialization for scenes that are flat. Right now, flat scenes get no reconstruction because the homography test discards all possible starting pairs.
For flat scenes, there should be reconstruction bootstrapper that uses the plane homography and not the 5 point algo to compute the initial two-view reconstruction.
See here https://github.com/OpenDroneMap/OpenDroneMap/issues/228 for an example of flat scene that fails to build.

Research direction
Start by tracing reconstruction initialization and the homography test that rejects all starting pairs for flat scenes. Compare the existing 5-point bootstrap path with the requested plane-homography path, using the linked OpenDroneMap example as a failure case. Done means flat scenes obtain an initial two-view reconstruction without relying on the 5-point algorithm.
