Projective transformation fitting

Question

Given set of points in 3D ( X = (x1, x2, x3), Y = (y1, y2, y3) ), how can I fit transformation from X to Y?

As far as I know this is called projective transformati

Answer 1

Projective transformations in 3d have an associated 4x4 matrix (modulo a constant multiplication). You can find the matrix with least square fitting.
