Hi everyone, I have the following problem. Suppose I have a set of n>3 point pairs ( (x,y)->(x',y') ). From this set I can create an overdetermined linear system and using for example least squares compute an affine transformation that when applied to (x,y) gives us (x',y') within an error...

first of all, thanks for the reply. I am sure the problem is, like you point out, in the confusion of transformation and rotation but I don't really get what is my mistake in equations 1-4. In my notes it states that if the transformation matrix for two coordinate frames is T then its inverse...

Hello to all, I am currently studying computer graphics and I have came up with the following problem. Consider that we have three coordinate systems, let's say CSA1, CSA2 and CSA3 that have the same origin and differ by a rotation. That is to CSA2 connects to CSA1 by R12 and CSA3 to CSA1 by...
