# How do I compute the fundamental matrix from 2 projection matrices?

Supposed I have 2 projection matrices in the form of P1 (3x4 matrix) and P2 (3x4) matrix, is there a function in opencv that could compute the fundamental matrix?

Apparently there's a function called fundamentalFromProjections: [http://docs.opencv.org/trunk/d7/d15/g...]) but I couldn't find it in opencv in python.
