Wrong stitched photographs in Hugin

I tried stitching photographs taken with a Nikon D600 + Nikon Fisheye 10.5mm + Nodal Ninja III.

The pan head is perfectly calibrated to rotate at the point of no parallax. The photographs were taken in RAW, then were exported in JPG, preserving all metadata.

Below I reproduce the steps I did:

1. I open Hugin 2013.
2. I select the simple interface.
3. I load the four images.
4. I notice that Hugin does not correctly detect the type of lens, and the multiplication factor of the camera.



5. I correct manually.



6. I click the "Align" button. But the result is unexpected: Hugin changed the focal length, and preview equirectangular picture is strange.



How I can solve this problem? Thank you.

Hugin Error Language

Hello everyone.

It is the first time I write in the forum. In advance, thank you very much for your answers. I use Macintosh in Spanish (from Colombia). When I start the program, I find the first error. An error message appears: "locale 'es_CO' can not be set".


Attempted fix from Hugin preferences in the menu: "Hugin> Preferences" in the "General" tab. However, the selector appears disabled.


How I can fix this error message Hugin? Thank you.

Hugin 14.0.0 optimize never completes

This is Hugin 14.0.0 on 32-bit and 64-bit linux platforms.  The 64-bit one is 8 fast cores, 12GB of ram, server class machine with a 20 drive disk array.

I have a couple projects I'm trying to stitch for which the Optimize ( Position + Barrel Distortion ) from the Hugin GUI never completes.    It gets slower, and slower, and finally subsequent itterations are hours apart.   I see no indication of the Hugin process running out of memory, or swapping to disk, it just seems to have gone into the weeds.

I'm not new to Hugin and have used it since its inception, so I have a general sense for what "normal" is.   In some instrances, projects which work and those which fail are very similar - same general venue, similar shooting technique and lens used, etc.   So I expect its just balled up some how.

So the key questions: 

1. How do you troubleshoot this?   Debug switches, setting?  Its obviously Hugin is doing a LOT of something.   The CPU utilization shows up in the hugin process itself.
2. The Hugin UI appears to be single threaded.   So the whole thing locks up when it is deep into a optimization run.   This is a not good design pattern for a UI, as any failure of the Optimize risks user data   The user's only option is to kill -9 the hugin GUI.   I'm not sure how horrible that would be to accomplish.  
3.  I suspect the issue is in the barrel distortion optiomation.   If you optimize for position only, it does complete.   But barrel distortion corrections are needed for the pano to stitch properly.  Is there a workflow which allows you to front end the barrel distortion analysis / correction so that this form of optimization is not required?
4.  Any other causes for this which can be avoided?   "Too many" control points?   Bad versions of support libraries?

 Thanks!

-- Bob

hugin crashing when mask-type is changed

I'm running the win32 version of hugin 2014.0.0 on a Vista system with 4GB RAM, and trying to align and enfuse a 3-image HDR stack shot handheld.  There is four distant objects in each frame that move slightly, so I want to include these objects from my first (best exposed) image only.  There are four masks in my project, and I wish to treat each of them as an "Include" mask.  I'm afraid I don't know where to find the log files that might help isolate the problem, so was hopeful someone here could assist.  I've tried this with images in 16-bit TIFF format, and in 8-bit JPEG format, but in both cases the application crashes when I try to change a mask from one type to another.  Any ideas?

Thanks,
Terry

Hugin making images more grey and losing color

Running v 2014.0.0.5da69bc383dd


See attachment.

Some things I notice:  
+ I have to increase blacks/contrast QUITE A BIT (typically-75 black on LR scale) just to get it to return close to normal.  
+ However, upon closer inspection, colors are lacking, constrast is greyer, and detail is lost.  I can adjust/compensate but it doesn't look as rich as the original
+ This never happened before, but with this version (the previous had the nociecam issue IIRC, which I asked for help about here as well, so I'd prefer to use the newest version) every pano  has come out like this.  I've "dealt withit', but I really like this view so that pushed me over the edge to get help.

I attached some photos.  

Single Image:  Image that is exported prior to stitch
WhatIexpectedtoLookmoreLike:  What the Preview stitch looks like - notice the richer colors
completenao_lessdetail_grey: Notice how it lacking in contrast, colors and etail.

I'm not adjusting/changing any blending parameters to my knowledge

Any advice please?  

Thanks!

Hugin Crashes On Both Windows and Ubuntu

I installed Hugin on a Windows 7 Pro machine yesterday to create a panorama from some scanned images of a newspaper page. I was following this tutorial - http://hugin.sourceforge.net/tutorials/scans/en.shtml. I am using an Epson V600 scanner and VueScan software.

I have eight scans of the one newspaper page in tiff files - 8 bit grayscale scans. I loaded the images and entered 10 as the HFOV. The program asked for the HFOV for two of the images, and then crashed. The specs on this computer - 

Operating System: Windows 7 (build 7601, Service Pack 1), 64-bit edition
Architecture: 64 bit
Free memory: 4224528 kiB
Active Codepage: 1252 (Western European Windows)

Hugin
Version: 2014.0.0.5da69bc383dd built by Matthew Petroff

wxWidgets: 3.0.0.0
libpano13: 2.9.19
Boost: 1.55.0
Exiv2: 0.24.0
Lensfun: 0.2.8.0

I then moved the images to my Ubuntu 14.04 machine, which has a better processor and more RAM. The same thing happened - Hugin crashed after entering one HFOV for the first image. The specs on this machine - 
Operating System: Linux 3.13.0-43-generic x86_64
Architecture: 64 bit

libpano13: 2.9.18 
Boost: 1.54.0

I will try to attach the detailed crash report - 7.4 MB, but not sure if there is a limit on the size of attachments. I will also try to attach the images I am using, again not sure if they will go through. I will send both the images and crash report to anyone who is interested in investigating these crashes.

If you have an idea on how to fix this problem, please let me know!

Thanks,

Mark Philips

hugin repository

Did something change with the mercurial repository?

 

I get with 'hg pull' (on hg.code.sf.net/p/hugin/hugin)

 

remote: abort: There is no Mercurial repository here (.hg not found)!

abort: no suitable response from remote hg!

problems tessalating

(I'm using hugin 2014.0.0.51ff237f209e on Ubuntu 14.04)

I am attempting to stitch together a set of tiles. These tiles
tessalate, but also have a border.

So I'm setting control points on the corresponding corners,
and setting a mask to remove the borders (i.e. only include the middle).

I can't use the obvious "crop"
since some of the tiles have been photographed at an angle.

All this has gone well.

But the stitching/blending has gone very poorly.
Masking appears to not ... not work, or at least do something
I don't understand. The mask only seems to be applied
where the source images overlap.

In the attached sample, for example, the top-left image
retains its left and top border, only being masked on its
right and bottom edges.

This can be seen easily by doing

   nona -m TIFF_multilayer -o tst hug.pto

And viewing the resulting multi layer tiff in Gimp.

If I let hugin (AKA enblend) stitch the images, I not only
get an unwanted border, but enblend goes a "little nuts"
if the masks areas don't quite touch. Pitch black pieces are created,
which leak and bleed a lot.

I attached a single image, and a pto. The 4 images in the pto
are simply copies of the one image.

Advise welcomed.

Fedora 21 rpms of current hugin default branch source

Hello All,
Anyone running Fedora 21 x86_64 who would like to install and test a build  
of the current hugin source can download the rpms from the Dropbox link  
below.
The current source includes a number of changes since the 2014.0.0  
release, the most recent being the replacement of the makefile stitching  
engine (pto2mk) with the new hugin_executor. This build also includes the  
ability to edit control points in the Fast Panorama preview window.
If you use script files to stitch panos these will need to be modified to  
use hugin_executor.

The link to my Dropbox is   
https://www.dropbox.com/sh/nwg8qgowasbts6u/AAD6pTkHzMgpQEiUi1ndBRJNa?dl=0

The packages available are ...
hugin-2014.1.0-0.11.20150216hg.fc21.src.rpm
hugin-2014.1.0-0.11.20150216hg.fc21.x86_64.rpm
hugin-base-2014.1.0-0.11.20150216hg.fc21.x86_64.rpm

You will need to install the hugin and hugin-base packages. The src.rpm is  
provided for anyone who wishes to rebuild for another version of Fedora.

You will also need to have libpano13-2.9.19 installed to use this version  
of hugin. That package is available at...
https://repos.fedorapeople.org/repos/bpostle/panorama/fedora-21/x86_64/

Cheers,

Hugin mosaic georeferencing with UAV GPS positions

I am using Hugin to create a mosaic of photos shot by a UAV. I have 60 photos organized in regular strips. The UAV flew at a constant height (70 m) on an area mostly flat. I have the necessity to georeference the mosaic obtained so I have to track the location of the shooting center in the mosaic. Hugin records these coordinates but I do not understand in which measurement unit ... how can I go back to the coordinates of the shooting centers in terms of pixels? I don't have control points so I have to georeference the mosaic using the UAV positions.


Thank you for any reply

fun with lensfun

Hi,

just by chance I noticed that the Lensfun project doesn't mention Hugin 
in their list of applications using their library:
http://lensfun.sourceforge.net/usage/

So I tried to make them aware of what I thought was just a little flaw 
but I learned that the lensfun developers _insist_ that Hugin doesn't 
use Lensfun  which I think is funny. See 
<http://sourceforge.net/p/lensfun/mailman/message/33389420/>.

So... is there some sort of hugin roadmap that either drops or includes 
lensfun? They just don't believe me.

Cheers,
Carl
