I've done a little research about triangulations and there are several methods (Linear, Linear LS, eigen, iterative LS, iterative eigen,...) but I can't find which one is being used in OpenCV. How should I use it? It seems that as an input it needs a projection matrix and 3xN homogeneous 2D points.

By definition, we have x = PX, x ′ = P ′ X. We can get rid of the homogeneous scale factory by a cross product. Therefore, x × PX = 0. This can be rewritten as. where pi⊤ is the i th row of P. grammarly abn
