Is there a way to get camera pose (position and orientation) from RPC images #352

By running stereo, it reports the distance between camera centers. Is camera pose estimated and stored somewhere?

The distance between camera centers for RPC is actually bogus (I put it on my to-do list to hide that at some point).

We regretfully have no way of knowing where the camera was. I guess the camera pose for RPC could be estimated, at least for pinhole cameras (such as SkySat), but we don't do that. Note also that many times the RPC approximates a linescan camera (such as for Digital Globe and Pleiades), and then the camera pose varies as the satellite moves in the sky while acquiring image lines.

Thanks for the explanation.
