Just tried with relative TrX,TrY,TrZ and yaw. Also, I understand that units must be pixels.
Now results make more sense. It seems I actually have problems that could be related to sync errors between the camera and the gps and optimizing using CPs will be useful. Nevertheless, using cpfind I get few CPs. Would it be useful using Autopano-SIFT and/or Panomatic? What do I have to do in order to install these methods? Also, what parameters should I optimize? I think that yaw, TrX,TrY, as TrZ should be pretty stable. Any other advice will be welcome!
