[hugin-ptx] Re: set up for calibration of a fish-eye lens

[Lars O. Grobe]

This is a follow-up to my own mail. I found some news about what 
equipment I have available, but a new question arised on conditions for 
calibration.

I thought about it again, but did not come to a real result yet. Does 
the luminous environment really have to be the same for the pictures 
taken for vignetting calibration? Or is Hugin using exposure information 
to correct for the luminances somehow? I am not sure if that would even 
be possible, but as the stability of lighting environment is the most 
difficult to guarantee for this set-up, I would first like to make sure 
that this is really needed.

I found that I will have a manfrotto tripod head available that should 
be fine to provide me with that functionality.

Thanks & CU, Lars.

[hugin-ptx] Re: Fisheye in a small room

[Jon]

Thanks for that info. I've read some about parallax and the nodal
point. I know the photographer didn't do anything to compensate for
that. So could that be the sole cause of the problems? I'll look into
some of the ways to avoid parallax you mentioned.

Thanks also for the links to the photos. I particularly liked the dorm
one, as that is what we are trying to capture - a dorm room. We are
trying to learn how to do these 360 degree panoramas for our
university website. This was our first set of test images.

Also, about the number of shots needed with the 10.5mm lens, does it
make a difference if the camera is positioned in portrait or
landscape? He shot in portrait, and even with 9 photos there doesn't
seem to be an excessive amount of overlap in some cases.

Thanks again.

[hugin-ptx] set up for calibration of a fish-eye lens

[Lars O. Grobe]

Hi list...

I have been asking a similar question a while ago, than had to move over 
to a different project, and now the same problem arises again.

I have a fisheye lense with a fov of about 185 degrees. I want to 
calibrate my camera/lens so that I will be able to reproject images to 
'perfect' angular fisheye projections, and correct for color aberration 
and vignetting at the same time.

If I got it right, I will have to shoot a set of images, rotating the 
camera both vertically and horizontally to get a reasonable overlap.

To determine vignetting, all that is important is overlap and constant 
light condition (ok, the latter is far from easy to achieve).

To determine the geometric lens parameters, first I will have to make a 
full 360 degree turn with sufficient captures, to be able to determine 
the exact fov. Having enough overlap and control points should also 
allow the various distortion parameters affecting the projection.

Now I am trying to translate this into an experimental set-up. I have 
made a simple extension for a tripod to be able to rotate around the 
entry point of the lens. But...

I will see the tripod on my images. Will this affect accuracy of the 
vignetting calibration?

I would perform the whole process on a nine-exposure HDR base. Should I 
perform corrections on assembled HDRs, or should I feed the LDR images? 
I was wondering if e.g. the detection of vignetting would become more 
accurate if I would feed HDRs as source images.

Does anyone have a hint what kind of extension to use for setting the 
camera back on the tripod, so that I can rotate around the right point? 
I have made a simple wooden extension, but that is a bit clumpsy, 
especially as it must NOT appear on the images (it rotates with the 
camera and most probably render my vignetting and color aberration 
calibration completely useless). I am not a photographer, what should I 
look for, any such extensions available like for flash-lights or other 
stuff? I ask cause I will need this hardware only once for the 
calibration. Later, I will take only single fisheye shots, no need for 
stitching, I only need calibrated fisheye views.

Thank you for any help!!! CU Lars.

[hugin-ptx] Re: Fisheye in a small room

[Seth Berrier]

I've done exactly this before: http://www.panoguide.com/gallery/547/

Now, I had a full 185 deg fisheye (which I think is around 8mm) and I was
using a nodal rotation mount (you can see pieces of it near the bottom, a
simple, home-made affair).  If your photos were not taken with a nodal mount
you may be SOL.

In general, I find getting the optimizer to converge with my own fisheye has
involved a lot of care.  I generally take the following approach:

1) Manually identify control points - I know, this sucks and autopano-sift
can handle it but the ones it picks just don't work right for me (and lately
it doesn't pick any at all ... probably related to removal of FOVs above
180).

2) CROP - Use the cropping interface to get rid of the fisheye barrel if it
is visible.  This should only be necessary if you are using a circular
fisheye.

3) Make sure you start with reasonable approximate positions - Edit the yaw,
tilt and roll values in the images tab and check the pano preview until you
get them approximately in the right place.  This will help the optimizer
avoid a local minimia.

4) Make sure you start with a reasonable FOV - I usually give it 180deg but
in your case It sounds like you know the actual FOV so this would be
preferred.  Note, however, that the final optimization may change this and
you should let it.  Again, this helps the optimizer avoid local minima.

5) Optimize:
   - First, optimize position only (either incremental or not, doesn't
matter).  Check the results in the visualizer.  If you're not getting good
results, return to your control points and add or remove as needed.  Repeat
until their placement is reasonable.
   - Sort your control points by distance in the control point window
and remove/replace outliers.  You can use your judgement here but since
we've only optimized position don't expect too good of results yet.  Errors
in the 100's to 200's of pixels are not uncommon especially if you were
sloppy with your control points or if the control points are near the edge
of the lens.  You should see a point where they jump from bad to not-so-bad
and anything above that should be thrown out.

   - Second, optimize position and view and follow the same procedure as
before adding/removing control points as needed.
   - Third, optimize position and barrel dist. and repeat as above.
   - Fourth, optimize position, view and barrel and repeat as above.
   - Fifth, select custom parameters and turn on everything (even a, c
and d and e).  BE CAREFUL!!  Things can go really wrong here so don't be shy
about undoing things if it diverges.  Generally, values for d and e should
be small and the values for a, b and c should be less than 1 in abs val
(thought for my lens ... which *sigh* is damaged ... I get distortion
parameters above 1 in abs val ... but never much above 1).

So, anyways, this is my process.  It's intense but the results are worth it
for me.  Hope it works out!

Seth

P. S. I have little justification for the steps above other than the fact
that they work for me so if I'm doing something that seems crazy ... it
probably is!

[hugin-ptx] Re: Fisheye in a small room

[Joe Templeman]

Hi,

I've had some experience with taking equirectangular panoramas so I hope I
can chip in some useful info. The main problem with shooting panoramas in a
small room is that everything is much closer to the camera. This means that
any slight movement left or right will cause parallax problems. If these are
too severe, you will never be able to get a perfect stitch, and you will
most likely have to re-shoot.

When taking panoramas you need to make sure your rotating the camera around
the nodal point of the lens. This is the point inside the lens where the
beams cross. If you get the rotation perfect, you will avoid any parallax
errors and should be able to stitch no problem. Its not usually a problem
when shooting outside, where things are much further away because the things
are much further away, the movement away from the nodal point does not cause
too much parallax and can be unnoticeable. You can google ways to rotate the
camera properly using string and weights, or a more expensive way to achieve
this is to use a panoramic head on a tripod. Personally I've managed to get
perfectly good results with a combination of practice and luck.

One final observation of mine is that 9 images with the 10.5mm is a lot.
I've only used that lens briefly, but from what I remember I was able to get
a equirectangular panorama from about 5 shots...

Hope its some help

Joe

how did you make the changes? I could apply Eduardo's patch, but I could 
not apply yours - neither before nor after applying his.

Because, we, the maintainers of libpano do not want to be sued for
breach of a patent
like Helmut did.

The change that Yuv pointed out was introduced recently - did you
update your libpano since then? before it was 720°. I don't know why
Bruno changed it - the old reason I remember is that there was a
patent concern on "defishing images over 180°" by Ipix, but that this

See for instance http://www.heise.de/english/newsticker/news/56009

Cheers, 180° or otherwise,

[hugin-ptx] Re: hugin and fisheye

[Seth Berrier]

Hmm, well this is interesting!  I've been using my 185deg fisheye with Hugin
for a while now!  The optimizer will pick FOVs beyond 179 (in fact, if I
don't set the cropping right I can get FOVs over 200 deg).  What's
interesting is that this has never been a problem for me (at least, that I
know of).
I'd say, go ahead and try it with your fisheye.  Make sure you select the
proper type of lens on the assistant tab or on the camera and lens tab.
 Circular fisheye is if you can see the outer circle of the lens barrel in
your photos and full frame fisheye if the image fills the frame so that
there is no circle.  I've done quite well with this setup and am happy to
help if you hit some obstacles.

IMO this is not a "pro" (advantage). When working on a common bigger 
"document", whether it is a Subversion repository or a Wiki, one 
important thing is to discuss conflicting choices and seek consensus 
rather than override other contributors.

Many of the points in 

 
apply also to Wikis, although maybe for a wiki it is different. E.g. for 
SVN best practice is to encourage many commits, while for the wiki Erik 
was complaining about frequent storage of changes.

IMO what Erik did discourages contribution. I've had a similar 
experience on Wikipedia a couple of years ago when I was a newbie 
contributor there. The result is that I decided that contributing to 
Wikipedia is not fun for me and have not contributed much since.

no.

Hugin supports fisheye images.

However there is an artificial limitation in Libpano, on which it is 
dependent, to 179° FOV. The way Hugin works this should be a limitation 
only on the use of full frame circular fisheye (e.g. 8mm on a full frame 
camera) when trying to stitch a full sphere in two images. If you shoot 
three images and crop them slightly, you're OK.

If the circle of your fisheye touches at least one of the sides of the 
picture frame, you're OK.

If you still hit a limit, the solution is to build libpano yourself, 
removing the limitation.



gives you the information you need.

you want to define a large enough MAX_FISHEYE_FOV

and you want to make sure you're allowed to do that in your jurisdiction 
(usual disclaimers of responsibility apply).

Mike,

Please open a new topic if the subject of your post is *completely*
different from what you are replying to, as you have now done twice.
This keeps the discussion list as clean as possible. Mixed topics are
hard to track, as you will probably agree.

Thank you.

[hugin-ptx] Enhancement request for Batcher

[Mike Runge]

I enjoy the new Batcher GUI.
Formerly I worked with a bunch for self-written windows-batches to
automize my workflow:
- one to run autopano-sift on all images with the same basename to create
a lot of hugin projects
- one to apply a kind of template on the projects created by autopano-sift
- one to run nona and enblend on a bunch of projects.

Now I use the batcher for the actions after having specified all
individual settings. I'm looking for the batcher to assist me as well
in the time-consuming actions that happen before I can individually set
controllpoints, optimize, etc.

What I would like to do:
- Drag and Drop a bunch of images that belong to one panorama on a
shortcut "create hugin project" and this will create a new hugin
project based my preferred template and it will add an entry to the
batcher tool.

- Once I have collected a lot of projects this way, I would like to start
the batcher and let it run on those projects (status: "Fresh" ) just
to create the controlpoints and verify them. Status needs to change to
"Waiting for next steps" after having performed.

- Now I can open project by project with hugin (from within the batcher)
and create some additional verticals, optimize, etc.
If I do a save, status will change to "Waiting"

- At last, I would like to start remapping and blending from the batcher
like it works today.

Do you think, that this would be useful and maybe will be implemented in
the future?

Thanks for your response,
mike

[hugin-ptx] Re: GSoC 2009 students and wiki

[Lukáš Jirkovský]

Hello Erik,
I took me quite a lot of time to decide if I should write there
because I feel I'm still new in Hugin/Panotools community. OK, now to
the topic:

I think these changes have more culprits than pros. What I think is:
1. these changes doesn't reflect purpose of these pages. In my opinion
user pages should serve only as personal presentation ie it contains
something like "My name is John Doe. I'm programmer's god and I hate
spinach" but nothing else. If I searched for GSoC project in the wiki,
the last place where I would search would be user pages. But If there
was someone who used the proposal page for personal info, it would be
meaningful to move this info to his/her user page.
2. the redirection is confusing. I clicked on link and I was
redirected to some personal page! What the heck?

Only pro which I can see there is that user page is editable only by
it's owner (the user himself/herself) so no one can interfere with
his/her work. But thanks to history of all wikipages it's quite easy
to achieve this even on "usual" pages. Also this may turn to be a big
con after the GSoC when the student may disappear and no one can fix
problems in this page (for example mark it as outdated or whatever
else).

Best regards,
Lukáš "stativ" Jirkovský

[hugin-ptx] Strange colours due to ldr parameter?

[Mike Runge]

I installed Allard's compilation 0.8.3716 for windows on a winXP PC and
it runs very nice - thanks for providing this version.

Like with all versions of hugin after 0.7 beta 3 (the last I have without
the exposure tab) I often have a problem with strange colours. If I do
the same project with 0.7 beta3 all is fine, with newer versions I get
unnatural colours in some areas.

How do I just completely switch off this exposure/ldr/hdr thing if it
causes trouble to me?

Thanks you,
mike
