Yeah, but even corner detection is not an easy task. Have you tried Harris corner detection, for example? It's far from perfect. And even when you have the corners, the issue of matching them remains problematic. Imagine you have two chessboard patterns. It will be easy to find the corners, but how will you know which corner matches which?Corners/edges should be filtered first to make features. Then you register the features. Features have to be robust in space and time.
In the end, details will be lost occasionally. Definitely not a perfect technique.
One company in US has made 3D satellite images in US and started from Tehran images! They are trying to sell it to the federal government.

Of course, problems like matching chessboard patterns are easy, but it gives you an idea of the issues arising in problems like that.
Yup. But they are doing that with more than one satellite. If you refer to the question I asked from Mohammad45 and Peed, you will see that I was thinking about the same, but for missile guidance.
