Basically it says when there are more than 4 points the set of equations Ah = 0 is over-determined and we need to

• minimizing residuals with Least Square

or

• adopt the so called singular value decomosition

OpenCV with findHomography which strategy adopts when there are more than 4 points?

Ps. I know RANSAC is used to choose inliner/outlier, but what happens when inliner are more than 4 points (the system is over-determinated with more than 4 points)?
