Hello, I'm working right now on a project which evolves transforming an image taken with a camera to a plane surface at an angle x and a height h into a view-from-the-top image. I searched which algorithm should I use and I saw that it is a matter of projective plane transformation but there I got stuck because i don't now how to express the "viewer point" if I want the real image to be constructed plane, as a map. Or should I search for something else? What should I use? your help would be highly appreciated. George T.
