Big Ben's Panorama Tutorials

No Optimisation

The first step is to stitch/optimise the images that form the main panorama, in this case, the three central images.  The images were shot at 120°, although I think I bumped the tripod in between two shots so something might be a bit out.  Having calibrated my lens previously, the ideal situation would just require a simple script to create the panorama.

Script

p w1000 h500 f2 v360 u20 n"JPEG g0 q100"

i n"image2.tif"

Seams

There are errors in all three seams, but they are most noticeable in the the right hand seam (look at the ladder, the fire place and the left hand end of the seat). It's going to be necessary to select and optimise control points in order to do a better job.

As you can see from this the "ideal situation" requires a greater deal of accuracy than many people seem to think

TIP: Notice that the yaw angle of the first image is -180° and not 0°. Seams near the edge of the panorama are very hard to edit. Placing the centre of an image at the edges of the panorama (yaw =  -180°) prevents this from happening with less than 50% overlap between images.
