Yup. Calibration makes up for any *stationary* interfering objects which is why you can have a very accurate fixed compass on a ship or vehicle. So the limitation Geoff points out is mostly a result of the sensor. However, all the tripod and parts of the head are not "stationary" relative to the panning camera. These parts also tend not to be symmetrical and the actual sensor is unlikely to be at the npp (which would be the center of symmetry.) Perhaps the effect is minimal (depending on the rig?) or it could be that 5º is about as good as it might get, without special attention to the design of the whole rig, whatever the quality of the sensors.

Unless you go for some very expensive sensors. -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
