That would be nice. There is no much feedback for this workflow/tools. > The documentation for pto_var is especially skimpy. > I know. It requires some knowledge of the pto file format. Until now nobody helped with this. The easiest way is to have a look on the photos tab for an existing project.

Your example images have a horizontal field of view of about 22 deg. With an estimated overlap of 40 % you will get an delta yaw of 13 deg. For pitch this is similar: The vertical field of view is about 16 deg. So you get an delta pitch of 9 deg. The 27 is to get the middle image of each row near to the horizon. This last one would not be strictly necessary. An easier way is to use a subset (maybe all rows, but only 2 columns), run the assistant and look on the photo tab and deduce the necessary angle/formulas. (Or load a subset of images and move them with the drag tool to raw positions and then look on the photos tab.) Also I assume the origin for the positions is bottom-left. > > No. It is a spherical coordinate system with 0,0 in the middle. cpfind is using the full sphere for calculation. So the origin is not so important, because the 0-360/-90-+90 deg boundary is taken into account. -- 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.
