I have committed the changes to support tilt of the camera in
PToptimizer and PTmender. See the  ChangeLog for details.

the new parameters are:

Tx, Ty, Tz, and Ts (for scale).

[hugin-ptx] Re: Tilt transformation...

2009-09-10 Thread Oskar Sander
Nice work guys!

2009/9/9 D M German d...@uvic.ca



 Now, the real question for hugin developers: can somebody create a
 branch of hugin that supports these new parameters during the
 optimization? shearX, shearY, tiltX, tiltY, tiltZ and tiltScale?



So trying to mentally picture these parameters in my head to understand how
optimization should be done.

 When assembling a mosaic camera position imagine subject beeing a plane
Xs-Ys  with  Zs constant,  and camera moved across a paralell plane  X-Y
(with Z=0).   What would these parameter represent?

*shearX,shearY   =  camera position in the camera plane, this would be
different for each picture taken
*  tiltX,Y,Z.  rotation around the camera node (shearX,shearY), also
different for each picture
* tiltScale,  I guess this afect scaling of the picture... (  how does this
relate to current FOV or an imaginary shearZ parameter?)


Am I on the right track?

Cheers

to be honest, I am not sure how much they will help for a mosaic. The
model for panos in libpano
is still spherical. But it is a matter of trying.

scale scales the tilt operations only. It actually scales the view
point from which the photo was originally taken.

I actually think that libpano needs a plain, simple, scaling option.
If you look at the PDF I sent, the scale
is a factor by which the field of view of the lens is multiplied in
those computations.

As I said, I am not sure what use it might have. But the feature is
there now. Perhaps for mosaic mode we
need to redesign the libpano internal model. we'll see.

Looking at the formulas, I have the impression that the inverse
transformation should not be complicated - but this probably means I
missed something.

The inverse operation of V' = Mx My Mz V is
   V = Mz- My- Mx- V' (1)
with Mx- defined as Mx but with a -theta instead of theta (rotation
around an axis can be undone by rotating by the opposite amount). You
just have to be careful with the order of the unrotations.

V' is known up to a multiplicative constant, and is proportional to
(x'/d ; y'/d; 1). So we find V up to a multiplicative constant by the
inverse operation (1) above, and x0 and y0 are obtained by:
x0 = V0 * d / V2
y0 = V1 * d / V2

Does this make sense?

[hugin-ptx] Tilt transformations....

2009-09-10 Thread Rogier Wolff


Hi,

I was reading stuff about tilt transformations and was wondering if
it would help me build a fitting pano for a bunch of pictures I took.

If it doesn't... this might serve as a hint as to what may be
useful and developed in the future 

The situation
-
I took a bunch of pictures from about 450-500m above the Dutch
landscape. In fact the first picture was around 500m and the last
around 450. There was some wind, so there is also considerable
positional shift between the first and the last image.

The goal

To build a panorama that doesn't have visible artefacts. This is
currently not possible with Hugin. At least I couldn't manage.

The Trick
-
If we assume that all pixels that I shot are in one plane (which is a
good approximation of the Dutch landscape), a hugin-like optimization
step will find the position and direction of the camera relative to
the plane. This is similar to what Google does from the areal images
they took. But their task is much easier as they usually take
photographs mostly straight down.  From the pixels in the plane, we
can project again to a panoramic projection that is nice to view. This
is in a way similar to what google earth does.

The problem is that if I get the plane as a temporary image, it will
be inifite in size because we included the horizon in the
pictures. And I would like the horizon and the sky above to be in the
final image, which doesn't get projected on the plane.

The questions
-
Is this already possible to stitch with current hugin/panotools?

Would the tilt/shift stuff be neccesary?

Does the current tilt/shift stuff help in this situation?

[hugin-ptx] Re: Tilt transformation...

2009-09-10 Thread dmg

Here are examples of the use:

This photo was not remapped:

But this one was:

 http://turingmachine.org/~dmg/temp/floorInput.jpg

and this is the output, merged (difference mode):

http://turingmachine.org/~dmg/temp/merged.jpg

It was optimized using:

# specify variables that should be optimized
v Tx1 Ty1 Ts1 g1 t1 p1 r1 y1

using 17 control points in intersections of lines of floor.

And remapped using:

o f0 r-99.5957 p-0.992759 y-3.69248 v94.6652 a0.00 b0.00
c0.00 g-726.252355 t558.903060 Tx54.770184 Ty-45.457790
Tz18.993815 Ts2.536055 d0.00 e0.00 u10 +buf

As you can see, the transformation works.




 and the output:

 http://turingmachine.org/~dmg/temp/floorOutput.jpg

 and this is a photo of the same place taken:

 http://turingmachine.org/~dmg/temp/floor.jpg

 In this case, there is a tiltX of 32 degrees, and a tiltZ of -11 and a
 shear of -125 pixels.

 I have also added 3 parameters to the parser: Tx, Ty, and Tz, which are
 angles to rotate in degrees; and Ts, which is a scaling factor.

 I have the inverse transformations done. they are described here:

 http://turingmachine.org/~dmg/temp/tiltEq.pdf

 I am struggling with the inverse ones. If anybody wants to help, I'll be
 grateful. This is the only roadblock to have an alpha version of it.

 Now, the real question for hugin developers: can somebody create a
 branch of hugin that supports these new parameters during the
 optimization? shearX, shearY, tiltX, tiltY, tiltZ and tiltScale?


 I haven't committed my code but will do soon. in its current state the
 optimizer nor the cropping works (we need the forward transform for that).

[hugin-ptx] Re: Tilt transformations....

2009-09-10 Thread dmg

All that is necessary is there, but it needs some manual work until
hugin is modified.

You need to edit the script before the optimization.

then export the script to remap the photos using PTmender.


BTW, hugin developers, any chance you can implement using a script to
edit the script before optimizing?

Well, it's a bug in windoze command line length. It can't be helped.
You could drop the number of images you're trying to align.

But, you can change the way you're calling autopano-sift by using this
arguments: --maxmatches %p %o %s.
Notice the %p instead of %i. This way you're giving apsc the whole
project file, instead of individual image names.
You also get some other bonuses by calling it like that, as it enables
feature classification in conformal space.

Also consider upgrading Hugin from here: http://hugin.huikeshoven.org/
Newer versions have a nice interface for multiple CP generators.

PS: consider upgrading you ram (3-4gb), it's dirt cheap nowdays and
you'll get a 10-fold increase when you get to the blending part.

[hugin-ptx] Re: Changing [OSX] hugin-mac AutoCP parameters is possible.

2009-09-10 Thread Allan Seidel
Hello Harry,

I thought OS X users should know that they could change the plug-in
parameters. Your idea to save multiple parameter versions for the same
plug-in type is a great idea. If it were me creating the Hugin interface I
would not have the parameter settings accessible only in Peferences. I'd
have the setting available in the context where it is used. In other words
the parameters would be visible and easily changed with a double click on
their representation.  One way to do this would be to have the Peference
pane openable to the settings location upon that double click. That same
concept could be applied througout Hugin where applicable.

I don't know how the different os packages are created. It seems to me
that one can code the parameter less plugin concept without needing to
change the current the OS X plug-in structure. Hugin knows all about these
plug-in files. It can easily read each plug-in's argument line, report it in
Peferences and then alter the argument if needed.

 Ah but Harry you can change easily the parameters for the OS X AutoCPs.
  In each of the OS X AutoCP packages is an XML property list plist file
 called Info.plist.  OS X will open that file using the Property List Editor.
 Using the editor you may change the HginAutoCPArgs key to be anything you
 want. You may even keep the plist open after saving the change so to quickly
 change the arguments for the next AutoCP run.

 Allan


 Hi Allan,

 Thanks for your reply. I know that you can do that as I myself created a
 couple of them after the first release by Ippei.
 The same plist editor also gives you the chance to change the name
 displayed inside hugin. So you can copy them, change the parameters and
 displayed name and you have a new plugin
 The problem is that many users simply don't know where these plugins are or
 how to open them.

 I want to look into the option where we have parameter less plugins that
 can be selected and configured from the new Preferences panel.
 That leaves you with only one plugin per AutoCP creator, but you can call
 it many times based on the settings.

Awesome. This will be quite useful (specially for some nadir shot that I
badly took and invested quite some time to redo).
I'm always impressed by the power of this software, and where it is going.

I don't think it's the command line length with only 39 images. I
think the correct path to autopano-sift-c.exe is missing.
Go under preferences, CP generators, then select autopano-sift-c and
choose edit. Then select the correct path to autopano-sift-c.exe (look
in the folder where you installed hugin, e.g. c:\Program Files\Hugin
\bin\autopano-sift-c.exe). Then it should work.

 Also consider upgrading Hugin from here:http://hugin.huikeshoven.org/
 Newer versions have a nice interface for multiple CP generators.


Rev 4175 has yet the new interface with multiple CP generators. Maybe
the installer is not yet updated to the new interface.

[hugin-ptx] Windows Hugin SDK and documentation

Hi Ryan and other Windows developers

I'm moving this piece of information to the main mailing list.

  OK, so we may create something working on more then one platform.
  reminds me that I did not yet even try on Windows. I'm stuck with not
  being able to build lcms-1.18a inside the Hugin SDK (which has 1.17).
 
  Yuv, check the .diff file uploaded to the Wiki for building the
  Windows SDK. It's just a one line change for lcms (1.18). The trick
  for lcms-1.18 is that you *only* need to build the lcms project, not
  the entire solution. lcms (the project) doesn't depend on the TIFF or
  JPEG libraries, so it should have no trouble building.

Thanks, Ryan - this did the trick.

I was going to add this bit of information, as well as document the lack 
of OpenMP support in the Express Editions of MSVC, to the page 
documenting the [Hugin SDK].

Then I realized that I was going to raise a conflict again: There is a 
major inconsistency in the document which stems from the definition of 
Hugin SDK.

When writing up the document, Guido defined Hugin SDK as the minimal 
stable binaries and headers needed to build and run Hugin.

To me it must be more than that. And to Ryan obviously too: lcms is not 
needed to build the Hugin binary. Hence it is documented as 64-bit 
Only. But as I found out, it concerns 32-bit as well.

The logical consequence would be to first define what the Hugin SDK 
really is; then to update the documentation and distributed binaries 
accordingly.

Ad's releases are to me the proof that the current SDK does not work. It 
becomes stale quickly as upstream tools and libraries evolve.

Worse: it leaves people like Ad dependent on the next binary SDK instead 
of giving them the tools and knowledge to update their SDK.

The [Hugin SDK] Wiki page should make people like Ad independent.

Hence my suggestion:

1. The [Hugin SDK] will document how to build each and every package 
upstream, including further upstream dependencies (e.g. Hugin depends on 
enblend; and enblend depends on lcms; hence both should be documented), 
for both 32 and 64 bit.

2. Distribute the SDK in two forms: one large archive containing 
everything (almost like the current one). It will become outdated, but 
here comes the second distribution: archives of individual packages. 
This way the faster evolving packages can be updated/distributed more often.

To achieve this, I suggest to expand on the current structure of the 
[Hugin SDK]. Add/document the missing packages (currently if I try to 
build enblend according to [build] instructions, I miss some bits).

For each package, note if it is:
- FIX: has not been changing for years and is unlikely to change any 
time soon (e.g. GetText)
- STABLE: evolves regularly and is worth updating to the latest stable, 
but is not critical (e.g. Boost)
- DYNAMIC: evolves continuously and is worth updating continuously (e.g. 
ExifTool)
- DEV: is critical to bleeding edge Hugin functionality, and it is worth 
following it in between releases when making test builds (e.g. libpano 
or Enblend and Enfuse)

Currently there is too much confusion. There are four pages documenting 
Windows builds. I would suggest integrating the information about the 
[patches] into the [Hugin SDK] documentation; and extracting the 
relevant information from the [incomplete] page.

In the end, there should be just two pages: one guiding the complete 
newbie through a simple [build] of the DEV packages (that's Hugin, 
Autopano-SIFT-C, Enfuse-Enblend, Libpano) with pre-built SDK binaries; 
and one documenting how to build the *whole* [Hugin SDK] from scratch.

it is likely the installer (depending on what the user ticks it writes

taken care of by the new interface, it should be changed, in the .iss files.

Ad did build rev 4175 from trunk and his build process is right. The 
Hugin binary is pretty much up to date (although using a more recent 
build won't hurt).

May be that the SDK still has an older version of autopano-sift-C.

[hugin-ptx] Re: Windows Hugin SDK and documentation

2009-09-10 Thread Ryan Sleevi

Or we can go the easier route (for end users) that I've been pursuing:

An automatable that handles it all for you ;-)

With the basic pre-requisite of
1) Sources for packages
2) The patches from me (already applied, but nothing to say we can't
automate that in the future)
3) MSVC Express Edition
4) Windows SDK (6.1 or 7)

It digs in and builds each part of the SDK - Debug  Release, 32-bit and
64-bit.

I'm currently using batch files as the means, but after working with the
CMake-ification of Enblend/Enfuse, I think there is enough capability (by
means of the external commands) that for the non-CMake'd portions (eg:
Everything *BUT* enblend/enfuse), we can call the appropriate tools (eg:
configure.bat for STLport, bjam for boost, vcbuild for the various .sln
based projects, etc). With my batch file setup, I've got it automatically
building everything through enblend-enfuse hands-free. Using the four basic
requirements above, I can kick it off, and step back and I've got all the
enblend-enfuse binaries. 

At that point, the distribution of the SDK needs merely concern itself
with the maintenance of
1) The patches 
  - Which tend to fix path resolution issues relative to the SDK for .sln
projects and add 64-bit configurations
2) The CMake configuration script
  - Which is used really just to find the various packages, determine if
they're built yet or not, and if not, build them using the packages
appropriate build mechanism.

This seems a much more realistic and reasonable scenario for getting people
started, and also resolves potential issues where, for example, a user might
want to alternative between statically and dynamically linking the MSVC
runtime (Legal concerns, performance concerns, functionality, who knows) and
issues w/ versions (eg: 2008 v 2008 SP1 v 2010 at some point)

Thoughts?

[hugin-ptx] optimization of calculations in PTmender

2009-09-10 Thread D M German


Hi everybody,

For those using (or wanting to use PTmender).

for the sake of maintainability I have used only matrix multiplications
right now.  I am going to wait until we are sure about their correctness
before I expand them.  

By the way, in the process of hacking the stack, I discovered that, if a
parameter is present in the 'o' line, an operation in the stack is
created, even if the parameter is zero, which is a penalty on speed.

Hugin outputs many parameters, even if zero. Removing them will speed up
operations a bit.

 I have committed the changes to support tilt of the camera in
 PToptimizer and PTmender. See the  ChangeLog for details.

 the new parameters are:

 Tx, Ty, Tz, and Ts (for scale).

 thank you for this!

the accolades should go primarily to Dev Gosh and Google.
Dev did the hard work.

I just integrated.

makes sense - just make sure that it is documented well enough so that:
a) a monkey like me can build the automatable from scratch
b) *when* things evolve and change, a slightly more expert hand can fix it

when I work on the project, I try to make myself redundant by 
documenting what I do and trying to pass on the knowledge to what will 
be our next generation of maintainers long after I'm gone.

[hugin-ptx] Re: Tilt transformations....

2009-09-10 Thread Carl von Einem

Hi Daniel,

in the optimiser tab there is a checkbox in the bottom
 [] edit script before optimising
I often use it to optimise the shear parameters of my scanned images.

That works but I'd prefer a solution for both shift boxes where I
could choose from a list of other available parameters using drop down
lists.

dmg wrote:
 
 BTW, hugin developers, any chance you can implement using a script to
 edit the script before optimizing?

Another idea about the optimiser tab: the yaw box normally has one
value that is in a different tab marked as anchor. I think that special
anchor frame should be easily identifiable by either using a bBOLD/b
font or some colour.

That anchor should also not be selected when clicking the 'select'
button (correct naming should be 'select all' btw). If the user checks
that frame directly it's his own fault...

Carl

ps.
What's the correct term for longer (floating) texts that are available
when the mouse pointer stays on some part of the gui for a longer time?
In this case they should show the file name of the frame instead just
e.g. '3(-136,240)'.

 there is only the .fig file there. other programs seem to expect a jpg or a

 where does it say that it is an .eps.


Sorry. I didn't pay attention well enough. You are working with the source
of the documentation and not with the generated documentation when you build
enblend.



 What program is meant to view the .texi file directly in all it's
 composed glory ?
 I've installed so many now I'm not sure what's going on.

 mick


As far as I know texi is only the text formatting ascii file which you edit
in a ascii editor like vi(m). You must first convert it to texinfo (makeinfo
file.texi) or to pdf (texi2pdf file.texi) or to html (texi2html) or to
whaever format.
I suppose you already read http://en.wikipedia.org/wiki/Texinfo.

At that stage I looked at texi to xml and xml to wiki as there are
converters for that, but none is really sufficient.
Also texi to html to wiki as there are also converters for that but none
really sufficient.

I'm sorry I can't help. I could only give some explanations.
I hope you find something useful.

Yes, you are right. I was mistaken. I thought Mick was working on the

'working' is the wrong expression. rag in teeth ?  gnawing on bone ?

so what is the way to view the document in all it's composed glory ?

man shows some of it
info shows some of it
perldoc shows some of it but I forget the syntax

[hugin-ptx] Enblend 4.0 messes image

2009-09-10 Thread Seb Perez-D

Hi all

I tried enblend 4 as described on the wiki, in Linux Ubuntu 9.04
x86_64. With a standard equirectangular panorama, I get the following
strange result:
http://farm4.static.flickr.com/3530/3907886322_4280aa77f6_b.jpg
This is a reduced version of the 1x5000 original.

When I create the image at a smaller resolution, the strange errors go
away. I've tried with OpenMP disabled at compilation, and with the
image cache enabled.

And when I use enblend 3.2, even at full resolution, it works and produces this:
http://www.flickr.com/photos/sbprzd/3907902566/

The command line used is: enblend --compression=LZW -o out.tif -w -l 15 in*.tif

The issue can be seen in the masks, using the option --save-mask:
http://farm3.static.flickr.com/2450/3908003514_f269b493b3_o.jpg
The mask in the bottom left corner (mask number 7) seems to be wrong.

Here are the different component images, before blending. Mask number
7 would go between image 7 and all the previous ones.
http://farm4.static.flickr.com/3101/3908003530_cb9bde9e3d_b.jpg

Does anyone have a clue how to solve this? I've gone back to enblend
3.2 for the moment...

Cheers,

Seb
