the sequence was shot by canon s80 at 1024*768 15fps,and i used automatic tracking function ,the 3d object plane seems stable and stick to the desktop fairly well,but the problem is the perspective is not matching, if u scroll to the end of the sequence ,u 'll find that clearly show up ,the right corner side of the plane doesn't match the edge of the desktop, why these happens and what could i do to fix that?
i followed the guide line of the Gnomon title camera tracking 101 ,and give mm the right camera parameters,ccd size 1/1.18",calculate the real sensor size by the 2/3 rule and ...
since the quality is quite low, should i add manual tracks or strengthen some of the automatic soft tracks ? beacause i know i should have got good result , for a simple scene like this,
any suggestions or clues? thank u
the project file and the avi file
