I'm currently working on that...

The Plane is currently located at z=-1 (straight in front of the 
camera). If you keep one camera at TrZ=0, then TrX,TrY and TrZ need to 
be multiplied by the physical distance between the camera position of 
that image and the plane.

[hugin-ptx] Re: Questions about options in autopano-sift-c 2.5.2 -- projection, lens-type, focal-length

[Brent]

I've already fixed bug 2858780 in my copy (just a arg parsing error)
and will check that in, but to really fix the handling of the options
I wanted to understand the intent of the multiple ways of setting the
lens parameters via the command line.   Does anyone know what these
settings were supposed to do?  Is the lens-type arg really just an
alias for the first parameter of the projection option?   Doesn't seem
to make sense to me, so I think I must be missing something -- I don't
want to go in and start changing things based on a misconception.

Hullo All,
I will throw a few cents worth into this, but not sure if actually
adds anything new to what you all know...

It is relatively simple to identify a number of points (minimum 4, I
think) that are common to two photos taken from different camera
positions, and derive the camera positions and angles. There are a
number of algorithms available to do this, some available in open
source libs.
If one can then identify a number of common points for which real 3D
coordinates are known, again a small number, it is then possible to
derive the 3D coordinates for any other points in the overlapping
portion of the images, hence a flat subject/control point plane
doesn't have to be assumed.
I suspect, but am not sure without doing a tad more homework, that
relative 3D coordinates are available without knowing any real 3D
coordinates for calibration. This may be enough to do quite a lot.

You may be implying what I said above, not sure.
So, I think one could use a similar arrangement to the current manual
control point picker gui, to identify points common to an overlapping
pair, pass those points to solver routines and have camera positions
and angles returned. From there, Robert is your mother's brother, so
to speak...depending on just what you wanted to do.

Cheers,
Terry

this is much further than what my (current) interest is. If we only have 
partial but enough information to align the images in space, making them 
a sort of "flat walls in a maze", then I can look at them from any 
place, and project them on another wall, maybe with orthogonal projection?

I can do the masking and cleaning manually. my interest is in stitching 
long linear panoramas where there can't be assumed to be a single long 
and flat wall.

yes, these are all very interesting applications, and they come first in 
terms of development/evolution.

[hugin-ptx] Hugin-2009.4.0 - the plan

[Yuval Levy]

Thanks to everybody for expressing your views on how we will move forward.

I see consensus in that we all want to move forward toward the 
integration of the layout codeline, and I think the following plan will 
satisfy most of us:

1. I'll branch out 2009.4 later tonight. I expect the release cycle to 
be a relatively fast one, a confirmation that you have all done a 
terrific job and that the integration criteria work.

2. After that Lukáš can integrated his deghosting codeline. My 
understanding is that even without GUI it fulfills all integration criteria:
- it builds on the major supported platforms
- it does not introduce known regressions
- it works as expected in (limited) tests

Sure, a GUI tool would be nice, but Lukáš should not take all on his 
shoulder. Other contributors with available time and maybe more GUI 
affinity can help too. To me personally his deghosting tool is already 
useful without GUI.

3. Once trunk builds with deghosting, there is another neat feature that 
needs GUI work in our integration pipeline. That's the [autocrop]. The 
feature fulfills the integration criteria too, it lacks a button / some 
GUI logic.

4. We're all eager to integrate the layout codeline. Unfortunately it 
does not fulfill the integration criteria yet - specifically it 
introduces a regression on Windows when adding images to the project. 
And there are the other bugs listed by James and Bruno. Bringing it into 
trunk before the critical ones are fixed would put us in a similar 
situation as with 0.8.0 and PTBatcher. I don't think anybody wants to 
see that. On the other hand it is critically important.

The asynchronous development model is based on the idea that resources 
are liquid. Nobody controls them. Contributors flow wherever they want 
unless we put an artificial barrage (like a trunk freeze). My goal is to 
remove bottlenecks and empower contributors.

One last word about translations: translations are welcome *any* time. 
There are a few checkpoints when translations are more welcome than ever:

1. when branching out trunk to a new release codeline. at that time the 
translation files are updated and in sync between the two codelines. The 
strings are unlikely to change in the release codeline, so this is a 
good moment to bring things up to date.

2. during the beta testing. translations that arrive during the beta 
testing are sure to make it into the release.

3. after a release candidate is issued. translations that arrive after a 
release candidate is issued may not make it into the release (if that 
candidate is declared a final release). but they will make it for sure 
in trunk and in subsequent releases.

having multiple releases is not an extra burden on translators. the 
quantity of strings are the same.

given the current status of trunk, I would not be surprised if we had 
one beta and one release candidate that becomes a final release. To give 
developers time to catch up, I will leave at least two weeks of beta 
testing before releasing the first release candidate.

My wish is that we have 2009.4.0 out by the end of October; and that we 
can release 2009.6.0 with deghosting and autocrop in November; and new 
layout in January as 2010.0.0.

Also my wish is that until then you have made me redundant. I would love 
to see other people stepping in (and will happily step down and learn to 
do some wxWidgets GUI work).

Yes it is broken with the current trunk, see bug #2858780:

http://sourceforge.net/tracker/?func=detail&aid=2858780&group_id=77506&atid=550441

I think that the method of supplying input that works at the moment 
is via a .pto file.

What we need is something that works with Hugin, so the plan is to 
release 2.5.1 which is the current 'stable' 2.5.0 with a major 
memory leak fixed and a fix to alllow paths with spaces when using 
.pto input.

No idea, current panotools uses '0' for rectilinear, '2 & 3' for 
equal angle fisheye and '21' for equisolid input projection (which I 
understand is the same as 'equal area' fisheye).

The autopano-sift-c --lens-type option uses '1' for rectilinear, 2 
for equal-area fisheye and 3 for equal-angle fisheye.

It will load low quality preview images first and get clearer
afterward.
The image itself does not get clearer. But the website will allow to

Thanks for your encourage to give us more motivation to continue

We are also thinking of supporting automatic stitching panorama

afterward on our website.

These warnings have been around for a while, I seem to remember that

[hugin-ptx] Re: Anybody use this Free Flash Panorama Hosting - You3DView.com

[Leo]

Learn quite a lot about copyright and license from your guys.
Will do our best to remove the images with copyright issues.

Just curious about copyright and license. Seems Google Image indexed
these panorama images and even cache them. Probably we will just crawl
as Google and just provide an index/search engine automatically and
allow people to view the panorama pictures by our viewer. As Google,
we can exclude the websites that have 'No Robot' text file. Is it
visible regarding to copyright/license issue?

Or provide an online flash panorama viewer which can view any panorama
pictures based on the user given URL.

But will still allow people who hold the copyright to upload as well.

[hugin-ptx] Re: (Probably very basic) help needed for build process on WinXP: missing files?

[J. Schneider]

Hi Yuv,

real life interfered a bit in the meantime but now I am back. And next 
weekend I'm going to help my sister move all across Germany and won't be 
at home much, but anyway, step by step ...

> I'm looking at the SDK (20090509, from Guido) right now, and I see the

I don't know what I did to my SDK before but after downloading anew it 
looks like this (right column is mine):

So the only difference is the wxWidgets version. Don't ask me why it 
wasn't there before.

So before checking all the dependencies again I just tried compiling 
enblend again. Now the errors are:
For vigra_impex:
1>.\tiff.cxx(83) : fatal error C1083: Datei (Include) kann nicht 
geöffnet werden: "tiff.h": No such file or directory

I have already chnged that one dependeny to ..\..\wxWidgets-2.8.10\src\tiff
as you suggest below. Somehow it is still not found.

for enblend:
2>d:\huginbase\lcms-1.18\include\icc34.h(154) : error C2018: Unbekanntes

and the same forth and forth.

   --

So now I recheck the dependencies and there is a bit more present:

..\..\STLport-trunk\stlport   NO
..\includeYES
..\..\include NO
..\..\tiff-3.8.2\libtiff  NO but now changed to

..\..\boost_1_39_0now YES
..\..\lcms-1.18\include   YES

OK. Rev 6512. I have got STLport now in my huginbase. Is it later to be

What I read on the wiki page mentioned above seems to be the same in 
short. Am I going to build the STLport iostreams library?
Anyway on the MSVC command line I get:

Looks like I started somehow completely wrong.

No. But the wiki says, I have to apply the libxmi-1.2.diff patch.
Where do I get it and how to apply a patch?

Got the bin.zip (glut-3.7.6-bin.zip) and extracted to

[hugin-ptx] Questions about options in autopano-sift-c 2.5.2 -- projection, lens-type, focal-length

[Brent]

Hi,
   I was trying to play around with the latest autopano-sift-c using
the stereographic reprojection for fisheye lenses.   It seemed that I
should be able to create a PTO file from the command line using either
--projection or --focal-length, but neither seem to work correctly and
I'm wondering if anybody has actually tried using these options.In
fact, it seems that there are some minor bugs in the option processing
(not advancing over the comma for the projection option), but even if
I fix those, it is unclear how this is supposed to work.   It is also
unclear how to use the options:   i.e. are the projection and focal-
length options alternatives to each other?   If using the focal-
length, does one also have to specify the lens-type.   Why is the lens-
type option have a different number scheme than the PT format codes
used by the projection option?

  The stopper right now, which I could go ahead and fix myself if I
understand the objective of these options, is that using --projection
sets the global FOV, but doesn't set the focal length in the internal
data structures (pd->flpix), resulting in the programming thinking
that hfov is infinite.

That should be me. There is a couple of bugs to fix before the layout
branch gets integrated with the trunk, which I should add the tracker:
  * Optimisation of position linked stacks with arbitrary control
points fails. There are control points with high error values
even when the result doesn't look that bad.
  * Focal length is incorrect for portrait images.
  * Crop factor is always 1.

It went a bit differently to that, most of the work was in refactoring
the image variables handling. There were a couple of new features: The
layout view in the fast preview, and the ability to force identical
positions of images in the same stack.

The layout view shows images in the correct position but undistorted,
with lines indicating the control point quality between them. A red line
implies there are control points with high error, a green line means the
control points are fine, and a grey line means the images overlap but
share no control points. Clicking a line edits the control points
between the images it connects.

Actually, the camera was ok, but maybe just use a wider angle lens and 
do mostly downward looking shots, and fly higher, if possible.

Flying higher will also make the mosaicing and interpretation of the 
pictures easier.

Btw. real aerial cameras (for example. UltraCam 
http://www.microsoft.com/ultracam/default.mspx ), as used by the mapping 
agencies, are probably 50 to 100 times as expensive as a Canon EOS 1D 
something.

One must learn to walk before one learns to run.  With respect to mosaics
and separate camera positions, hugin has just learned to walk (or crawl
maybe)

If one wants to take the mosaic generation further to create an ortographic
image, or another proper synthetic perspective, a "terrain model"/3D model
of the subject is needed.  The current plane model is a good start though.

In a stereo application features' (e.g. control points') 3D coordinates can
be determined by overlapping photos, if the camera positions and angles are
known in beforehand.   Here we now do the "opposite" by determining camera
positions based on the assumption of the flat subject/control point plane.
To do both things, instinctively I think more information is needed.

For example imagine a mosaic combined of groups of stereo pairs where some
of the photos are with exact known relative camera positions, in these
overlaps, control point 3D positions can be determined.

If we want to build entire 3D environments so we can walk through it, 
then yes, every plane must be identified.  And every edge of those 
planes.  None of our automated CP generators can do that.  Although we 
are getting line detection.  Maybe they can be combined?

What we might need is a new optimizer that calculated the distance a 
point is from the plane and a CP clean that removes points that are 
furthest from the plane.  The control points on the anchor images 
identify the plane.

My interest in using the Tr Ti is for placing the a nadir shot that was 
taken off NPP, for removing a reflection in a mirror by taking an 
additional shot, or for assembling spherical panoramas that were taken 
handheld.

Seems like i've been saying this all along.  Looking at color and area is a

Your right with 3D and that control areas are needed instead of control points.

maybe I am just sleep deprived and dreaming... but isn't the logical

consequence to define a new type of control points: plane? and go "real 3D"?



The plane control point would be similar to the line control point. I am

not sure yet if it must be defined between two shots, or if it also

makes sense to define a plane on a single pictures. Mathematically three

points are always on a plane. We'd need more than that to make it a

constrain (the constrain in case of the line control point is two points

*and* the sphere. If we relax the assumption that all CPs are on the

sphere and go real 3D, we need a constrain to replace the sphere.



Once in real 3D space, we can place whatever target geometry (sphere,

plane, etc.) wherever we want and project onto it.



Or am I missing something?

Thanks for the link.  While I do understand what people are saying about

I'd be interested in using the site to host some of my pano's.  It appears to

Yes, I fully agree with this. Also because the hdrmerge part of deghosting
is only accessible from the command line. Hugin_hdrmerge, being a Gui part
for so long, "demands"  that the new functionality can also be accessed from
the Gui otherwise 95% of the users will never benefit from it.  This will
take some time and will delay the 2009.4 release. (deghosting_mask is a
stand-alone command line tool anyway and is not relevant as such or
obstructing anything in the release)

Yes, for the above mentioned reasons. What is meant with "Release now": A

[hugin-ptx] Testing of SoC 2009 layout track

[Oskar Sander]

Hi,

I though I might test this one trough a bit more.  (note one bug report in
the tracker so far)  a couple of Q.

* Who are active developers in this track?

* I'm not so sure what functionality there is in the layout model, is this
the best description? [1]

Hello,

I support getting a release out before the deghosting comes in.  It is  
good for morale to have one's code released soon after it finished  
(assuming it works of course!).  The gsoc students I'm sure would agree.

Is there something about calibrate_lens or cpclean that would work  
better after deghosting is merged in?

I understand there is some work wrt to translation though, and  
apologize if I am underestimating the amount of work required to keep  
the strings up to date.

Best regards,

Gerry

[hugin-ptx] Re: Anybody use this Free Flash Panorama Hosting - You3DView.com

[Yuval Levy]

that's unacceptable! you've misused images without a license. this is
like taking a bus ride without paying a ticket; just say sorry or made
them private is not enough. You have no rights to use them unless given
explicit permission by the copyright holder. You can find images that
you can use by searching flickr for equirectangulars that are licensed
under Creative Common licenses. And even there, you must abide by the
licensing terms, i.e. if they say no commercial use or no derivative,
respect it.

you wouldn't like it that people steal your software, would you? or take
your car for a ride?

owner of the images should send a DMCA notice to your host at
ab...@dreamhost.com and get you down.

Unfortunately the source code for PTStereo is not released.  The morph

We wont need to define a new annotation to identify control points 
belonging to a particular plane if we assume all control points of an 
image that is using Ti or Tr are of the same plane.  But this will only 
work if the plane can be something other than z=1.

I think the trunk is quite stable and could be released in a couple 
of weeks.  There are only a handful of new strings for translation 
(which are not in the .pot/.po files yet, needs doing).

So do we want a 2009.4.0 release with cpclean and lens-calibration

[hugin-ptx] [OSX] GSoC2009_layout with XYZ bundle for MacOSX - please download and test

[Harry van der Wolf]

Hi Mac users,

Just like Yuv I built a gsoc2009_layout bundle against the latest svn
libpano13. If you don't know what it's for: please read the discussions in
the mailing list.

Due to the fact that I was and still am ill, it took a bit longer as I only
work at 5-10% or so right now (doing absolutely nothing is also boring). For
the same reason I did not do much testing on this build (can't find my
concentration back).

To copy from Yuv's mail:
WARNING/DISCLAIMER: the archive is highly experimental, not recommended
for production work. unintentional damage may be cause to your system -
use at your own risk and danger. it is provided only for
debugging/testing purposes. don't expect any support. We are looking to
learn about how the new layout mode and the new XYZ transforms work.


Note: As this is technically a 0.8.0 build it will use the "old"
autopanogenerator configuration. Keep that in mind in case you already
removed the old plugins. You can always download them again from my site.
Note 2: Being a 0.8.0 build also means that you will find it in the 0.8.0
section, so you have to scroll down a bit.

Please test and give your feedback to the mailing list.

As always: Information and binaries via my website
.
(The binaries itself are, as always, served from hugin.panotools.org who
kindly provide the disk space and bandwidth).

Hoi,
Harry

[hugin-ptx] Re: GSoC2009_layout with XYZ for Windows - please test

[Oskar Sander]

Now were getting somewhere. This with video framegrabs (not HD). The
deck-plane represents projection plane and all CPs are on it.

In this real-life application the subject will always be more or less 3D. I
expect the plane-assumption will cause stitch glitches and labile
optimization because of imperfect CP geometry.

Therefore I don't think it is guaranteed that the "correct solution" is
represented by one strong unambigous optiumum solution, but at least
hofefully a local minimum.  Therefore it is important to guide the
optimization in the right direction.

For these two mosaics I did this by forcing only XYZ optimization first,
then adding angles in the next run. That converged nicely, and exposed a few
CP that were completely off. Other things i can think of are:

* Observed initial values - Some UW mosaics uses ROV that captures XYZ
position and ypr of the mission. These are then used as starting values in
the optimization
* Determine lens distortion parameters before, and use as starting value.
* An iterative optimization strategy much like the one used for panoramas
where XYZ is iteratively optimized around anchor, then ypr


BTW, What are the units of XYZ?


Cheers

Thanks for pointing out. These panorama are for test purpose. I made
them as private.

Thanks for your replies. Should know you earlier. Then I will not
waste time to work on it. Seems 360city has the same idea and
is already quite good.
