The discontinuities go away with a better fit. The pop up after each optimize attempt tells you a lot about how well it did. I only tried a few combinations and found the two extra parameters that make the most difference. I didn't test whether adding just those two to the basic yaw, pitch and roll would be enough. These and a few others were definitely enough and the following two were most of the improvement. The lens b parameter: I think I understand why, but I'm not sure enough to post that where others here understand that better. The translation y parameter: When you changed the pitch (upward angle) between photos, you did not rotate on exactly the perfect axis for your lens, so in effect you changed the vertical position of the camera in addition to the vertical angle. As long as the important parts of the subjects where they cross the boundary are all the same distance away, that deviation from perfect picture taking is fixed by optimizing the translation y. -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
