I am tracking the movement of an object inside a cube using two cameras - one above and one side-on.
I need to recreate the 3D path of this object in world coordinates however I can't use checkerboards etc to calibrate the cameras because the tracking data is being processed by another piece of software which imposes its own origin on the data.
Is it possible to use something similar to Matlab's triangulate function but without access to camera matrices? perhaps using the corners of my cube instead somehow?
Thanks for any help,
