Hello Everyone,

     Sorry this isn't exactly java but I was thinking about writing
this piece of software and I didn't know if there is allready one out
there. I want to write a program that compares two live images (from
webcam's perhaps) of the same object, but at slightly different angles
and have the software estimate the distance the object is from the
cameras.

Does anyone know of software allready out there that does this?

Thanks
