I use Mei calibration which create unified camera modelisation. I want to triangulate 3D points from two known camera position and there match in two image.

Here is a draw of the problem

I can't find any information to estimate the 3D point P from two camera view.

Can someone give me article which deal with it?

Take at look at this prototype module called Mapping3D. It contains a couple of classes and functions to help you do just this.

As I quickly look, the example you gave me, is based on Pin hole model and not on Mei calibration model.

Well, if you can turn the pixels into a line of sight vector, and you've got your tvecs and rvecs which should remain the same, you can use the rest of the functions. I'm afraid I don't know what Mei calibration is.
