PointstoWorld function does the conversion of image points to the real world representation. The real world is some times called as target. It does the reverse homography conversion of the image points.

[Ix;Iy] = R*[x;y] +[Tx;Ty];
Ix and Iy are the image x & y coordinates. R is the rotation matrix. x and y are the original target points. Tx and Ty matrix forms the translation vector.
