### Triangulation

Q. I am trying to come up with a way to track points in 3D space. I havebeen able to come up with an algo to recognise and track objects based

on their color.

What I have is two sets of 2D track points( X Y points ) that I

acquired from two camera views( one Vertical and the other Horizontal

,i.e., the planes are perpendicular). What I need is the corresponding

3D coordinates( X Y Z ) of the object of interest. The Video images

were taken from both the views simultaneously.

I have scoured the net for papers and methodologies, but have not come

across similar work. I will put in points what I need :-

1. A method to do the conversion from 2d to 3d coordinate sys.

2. Links to papers and websites referring to similar work.

Thnx in advance..

A. Try a paper called “Triangulation” by Richard I. Hartley and Peter Sturn.
