Error in creating panoramas

[rstinghe]

Hi,

 

I am trying to stitch a panorama with quite a number of photos (42, each of about 50MB). It all works fine, I can see the previews ok until the end step, when the result is all pixelated and scrambled. I suspect it has to do with the size of the files but I was wondering if anyone has any idea on how to address it? I have a PC with 32 RAM.

Thanks

Have you tried it with less photos?

E.g. the first 5 from left to right

Good morning @rstinghe. I have been toying with the idea of getting a copy of PTGui for my panoramas. It’s not cheap, and it’s a bit of a “one trick pony” but I’ve found (working solely on their trial version) that there’s a lot less clean-up after a merge. And, it’s really fast and more complete than most mere mortals could ever need. There is a trial version (30 days, I think) that gives you watermarked results, but it’s fine for evaluation. If I were you, and no other suitable solution presents itself, I’d consider downloading the trial version and running your pano through that. See if it works for you.

I'd try what carl123 suggested
I have a test sequence comprising 30 files ~40MB tiffs each 5568 x 3712px
which is a bit smaller than yours but works very well ie
Takes 13s to show previews
Click stitch, takes 63s
Click OK, takes 54s
Click Apply, takes 2s
132s total
16013 x 14989 final size

smadell's advice is worth following, I am too tight and use Hugin. The interface is a bit of a struggle for me and usually gives rise to the odd expletive or seven but the results are usually excellent especially if you're using HDR sequences where Photo fails

Hi again, @rstinghe. Both Hugin and PTGui are graphic interfaces coded on top of Panorama Tools (a free set of panorama-centric libraries). Because of that, both have similar capabilities. The problem with PTGui is that it's expensive; the problem with Hugin is that it has an extremely confusing interface. I've tried Hugin and found the UI so, so irritating that I abandoned it virtually immediately. It has a reputation that is similar to GIMP – powerful, but with an interface from Hell.

I think it's worthwhile doing what @David in Яuislip suggested. That is, try to put your panorama together in smaller pieces and then stitch those pieces into a larger whole. It's bound to take longer, and might end up being frustrating. But it will save you the expense of PTGui and/or the pull-your-hair-out experience of Hugin's interface. If you're happy with the process and the result, well then - there's your answer.

Both Hugin and PTGui can be tried out without cost. (Hugin is open source software, so it's free to download and keep.) If you get better results there, then you have to make the call between cost and convenience. Personally, I would buy PTGui rather than put up with Hugin; you may feel exactly the opposite.
