At this point I have done a ton of research on this. You can't use a compass by itself because it suffers from a lot of interference (hard and soft magnetic interference, it's called)
You can use a gyroscope but only for a short time (30 seconds, maybe) and after that, it 'drifts' and you get inaccuracies. you can use all the sensors together, this is called sensor fusion, and that way each sensor sort of helps to calibrate the others. with this you can get something reasonably good. But in the end the sensors have to actually have been calibrated somehow. The problem is that the sensors you get are not calibrated. You can buy sensors that are calibrated, and they are *very* expensive. Here is one: http://www.vectornav.com/index.php?option=com_content&view=article&id=45&Itemid=10 This sensor also comes with sophisticated software (using a kalman filter, and other fancy stuff). I guess it's sensors like this that you might find in really critical industrial or military applications. So to have something like this for your camera, well, it might cost as much as your nice DSLR and lens. -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
