Default Ribfest Panos

Every year the Sparks St Mall puts on Ribfest, a BBQ cookoff competition. It's not nearly as big as many of the real cookoff competitions, but it's a big deal here. Sparks St is downtown, running right through the major business district. Lets just say that lunch during RIbfest is a no-brainer.

I was out the other day and took some Panoramas of the booths. These thats are simply HUGE!

Interesting panos! and you're really getting good at Hugin. You just need to learn a little of the extras. Perspective and straightening adjustments in Hugin are actually dead easy. You could rotate to fix horizons on the slant, but it's actually easier to just set horizontal or vertical control points prior to stitching. You can also drag stuff around in preview prior to stitching to fix the POV. You can do these adjustments either before stitching, or afterwards. Generally, you'll only need to manually define one or two points for this.

For example, with your first pano, to get rid of the vanishing point perspective (if you want to), you can easily accomplish it by just setting a few vertical control points. First, you load the stitched pano as a Panoramic (cylindrical); you can just guesstimate the FoV.

Then, you click on points that are on a line you want to be vertical. They don't have to match feature-wise (actually, it's better if they don't). Setting them as far apart as possible on the same line (i.e., a control point at the top of a line, and the other at the bottom) is actually best. When you add the point, it'll be added as "vert. line", rather than normal.



Then, you use the optimizer to fix the "Positions and View". Hopefully, you get relatively low pixel offsets--ideally below 3 (in the example above, I got a max error of 2.59 pixels--that's good enough for me). Then clicking on the preview will give you an idea of what the corrected photo will look like:



Then you just stitch again, and crop and the perspective's been corrected:



Obviously, you can also set these types of vert. line (or horiz. line) points prior to stitching to keep your horizon from tilting. It gets done along with the stitching.

Great collection of images, Os. Those booths are unbelievable!!! I've never seen anything like it, and I live in the south!

So have you tried them all yet??
