The information is there in sequences of images through parallax precisely when the camera translates. We know how to do 3D reconstruction of scene geometry from a single moving camera.

Skip to 1:15 to see a textured reconstruction.
The first real-time example was Davison et al's MonoSLAM paper of 2007, I think.
- fryguy 12y agoKeep in mind that SLAM assumes a static scene. To stabilize a video with a moving target would mean that there's still going to be parallax otherwise you're going to get shadows (see the cool video on Oculus time warp: https://www.youtube.com/watch?v=WvtEXMlQQtI https://www.youtube.com/watch?v=WvtEXMlQQtI)
- robotresearcher 12y agoPeople are now managing to segment parts of the scene by motion, so that moving cars and pedestrians, for example, are known to be distinct from the camera's ego-motion. The static scene assumption is not strict any more.
