2D image to 3D world triangulation

In this post I am interested in triangulation, - the technique of inferring the 3D position of an object from two images of this object, taken from different viewpoints. The technique relies on the ability to find corresponding 2D points in two images. In this sense the triangulation is a 'poor man's' 3D location estimator.
2D point correspondence + Triangulation -> 3D location
The initial set up is below.
