This is a challenge that would put smiles on the faces of thousands if any of you or all of you were able to solve.
Artists like me around the world need our tech counterparts to crack the code of commercial camera tracking software and offer an app as open source. The math has been studied and is out there for the viewing http://www.ics.forth.gr/~argyros/mypapers/2005_xx_journal_cviu_camera_tracking.pdf
We just need geniuses like yourselves to take pity on us and put it into an application we can use. So the challenge is issued on behalf of 3d artists around the globe- build a match moving app we can use commercially for free, or at least dirt, dirt cheap (it would be nice if it went to all the major packages, but at the very least making the camera info exportable to blender would be great).
