How to position an object in 3D space using cameras [closed]

Question

Is it possible to use a couple of webcams (or any camera for that matter) to get the x, y and z co-ordinates of an object and then track them perhaps using OpenCV as it moves around a room.

I'm thinking of it in relation to localising and then controling an RC helicopter.

Answer 1

Yes. You need to detect points on both images simultaneously and then match the pairs that correspond to the same point in the scene. This way you will have the same point represented by different coordinate spaces (camera 1 and camera 2).

You can start here.
