Does anyone have any image sets, particularly ones that don't blend well, that they could share for testing purposes?

[Monkey]

I'm making a new version of Multiblend but I don't have a lot of panoramas/mosaics to test it with. Does anyone have any image sets they could share, perhaps via Google Drive, particularly ones which have proven problematic to blend together?

360s x 180s, gigapixels, planar mosaics and such would also all be good, but I'm mainly looking for the kind of "Automatic" mosaics that show wide variations in white balance, exposure, and focus, or ones where there is minimal overlap between images.

I just need JPEG sets, plus a PTO file if you happen to have one.

I won't share results with anyone except the uploader, unless explicitly given permission to do so.

Thanks in advance!

Hi Monkey … these are links to some file sets I have on Sync.com.  Let me know if they are useful.

Perfect, thanks!

Hi Monkey,

I'm finishing a virtual tour that includes 8 street-art flat panoramas. Some are 30 meters wide.

Is it the kind of pano you're looking for?

[David W. Jones]

Interesting. I ran the Curacao JPGs (the ones with the same names as the
ARWs) through Hugin's Assistant. Didn't see any seam issues. The color
on the right 1/3 looks wrong but I didn't start with the ARW files or do
anything with the color.

When I followed my usual manual process, the images didn't come close to
aligning. Three had good control points, two were placed very weirdly.
After the Assistant got through, I viewed it and used the Straighten
function.

Anyway, nice pictures, I hope they're useful for testing blending.

Hi Laurent,

Those sound ideal, especially if they exhibit change in lighting or exposure. Loss of contrast is one of my remaining problems with Multiblend so even well-matched images will be useful for that, and if the panos are big that will help test caching.

[Abrimaal]

Yes, sure. These are only 3 images. You are great if you find control points on the white background of Hugin.
Normally, when viewing in full screen I see where I should add the points.

Hi Monkey !

I send you my contribution. It is a spherical panorama taken with an Andoer Pano Head and a Samsung Galaxy S8. You will find in this order:

1 shot at Nadir (useless because I always forget manual focus, so the focus is on the tripod :)

9 shots at -60° pitch, spaced 40°

12 shots at -30°, spaced 30°

12 shots at 0°

12 shots at +30°

9 shots at +60°

1 shot at zenith

every row starts at the same heading.

I enclose my PTO. The Panorama does not stitch well, it always have incorrect lines joining. 

I try to correct with some masks, at least to have "complete" buildings, but then the problems appear in adiacent areas.

You can download a zip here:

let me know....

Hello Monkey.

Are parallax issues in your field of interest?

I have several sets of images that I took before making a panoramic head.

I should still have one set that features:

- moving construction machinery

- nodal point displacement in radius about 12cm (5")

- camera shift due to wind

- objects in proximity 2-3m from camera

- possibly traffic in distance

The images were made for HDR - do you find that useful or is a single layer set enough?
