|> What I want is to determine the coordinates of these "target" points, based on the transformation determined by the corresponding "known" points.
could you please elaborate? Do you know the corresponding point pairs (known_i,target_i)?
There are many "transformations", I remember seeing a projection model based on a 4x4 matrix in uni.
Determining the entries would mean to solve the resulting linear equations.
Again it depends on the class of allowed transformations.
