Shooting a subject from all directions, similar to cartography

Hi,
I was thinking recently about all the different techniques that are made possible or more powerful by combining multiple images (panorama, hdr, focus stacking, etc) and it seemed to me one had not been tried yet: shoot the same subject from many directions. Sounds like the dual of panorama photography, whereby one shoots in many different directions from one position. Kind of swapping the photographer and the subject. Like most ideas I come up with, it's not new. In fact it's about the same, geometrically, that's done when mapping the globe to a surface as in cartography. Not even new in Hugin circles, see https://groups.google.com/forum/#!searchin/hugin-ptx/globe/hugin-ptx/kju8CPAgOOY/TUfB8AAHqJwJ. Despite doing my best to follow the advice in that thread and plenty of experience with panorama photography in Hugin, I end up with results like this:


This is my process: The object, a fruit bowl, is on a stool with a dark background, camera on a tripod. Shot 17 pics at approximately regular angular intervals by rotating the subject, not moving the camera. The distance remains consistent this way. Light is soft, a little stronger from the left. Adjusted curves in Aperture for all pics, imported in Hugin. Use cpfind to find control points with option --linearmatch to reduce spurious finds. For most pairs, control points are on the bowl, for a few on the background and support. Fix manually. Add  horizontal line to each frame to avoid snake like stitch. Optimize positions first, then release a few parameters at a time to see what happen. Image above is obtained by optimizing everything. a, c, d,e, g are nontheless 0, TrX, TrY, TrZ almost 0. Plane yaw and pitch are mostly low, with a couple of outlier images. Worst distance is 25, most < 4.  I am aware that parallax changes will make it challenging to map the fruit in a continuous way. I am just focusing on the bowl and no cps are on the actual fruit. Does anyone understand what is going on, let alone how to fix it? Thanks

lensdb - too generic name for binary?

Hello,

/usr/bin/lensdb in hugin seems to be a too generic name for a
specialist tool. ("Manage the database of lenses used exclusively by
the hugin toolsuite.") This might generate conflicts and
misunderstanding later on, if when something like digikam or shotwell
added a commandline interface to a database of lenses. How about using
hugin-lensb or lensdb-hugin?

If that was acceptable I could try to come up with a patch.

I can not judge, either. But api-max was set to 2014.1, so I assume that
these scripts were activated in the development version. I'd expect that
a breakage would have been noticed there.

If this is true, it seems that no one cared during the development cycle
then. Wouldn't it be more honest to axe woa if nobody gives a damn?

German translation started

Hi!

This is just a heads-up that I downloaded de.po from 
<http://sourceforge.net/p/hugin/hugin/ci/default/tree/src/translations/> 
and will start translating new strings this evening.

For those who are interested in helping with "their" language version of 
Hugin: please have a look at the Hugin translation guide at 
<http://wiki.panotools.org/Hugin_translation_guide>

Looking forward to test 2015.0 beta 1.

Cheers,
Carl

EXECUTABLES
Users communities produce executables for their respective platforms. They will be announced in this thread.

CHANGES SINCE 2014.0.0
Hugin 2015.0 has a number of new features. Most of the changes are under the hood to improve stability, allow easier maintenance and easier addition of new features.

The makefile based stitching engine has been replaced with direct calls to the underlying programs. This should reduce the overhead of calling the same program too often and so speed up the whole process.  Hopefully this also allows the usage of more unusual characters in the filename. Instead of pto2mk and make we now have hugin_executor which can also be used for running the assistant from the command line.

Hugin now has it's own blender, verdandi, based on a watershed algorithm, which has been included in 'nona'.  verdandi can be chosen as the blender by choosing "builtin" in the stitcher tab, and can also be set in  the Preferences. verdandi can also be called as a command line tool.

The lensfun library has been removed as it did not fulfill our expectations. It has been replaced with our own camera and lens database which uses a data mining approach and operates automatically without user intervention. Geometric distortion and vignetting data have to be loaded manually.

The fast preview window has a new tool to add or remove control points to selected areas in the output projection.

Automatic exposure stack detection is now applied when loading images, and an option has been added to unlink image position when adding stacks.

The fine-tune and auto-estimate functions in the control point tab have been made projection aware. It should now work also with images with different fov or different projections. The fine-tune feature has had a significant speed up when Hugin is compiled with the libfftw3 library (optional).

PTBatcherGUI has more choice for the end of the process: depending on the operating system the PTBatcherGUI can be closed, the computer can be shut down or send to the hibernate mode.

PTBatcherGUI now shows the thumbnails when searching for images in directories.

Many of the underlying tools in hugin are now able to use available cpu cores.

New tools added:

    verdandi: tool for image blending
    hugin_executor: stitching and run assistant from command line
    lensdb: tools for lens database maintenance

Other Improvements
* Many more improvements and bug fixes.

UPGRADING
Upgrading from previous versions of Hugin should be seamless. If you do have
problems with old settings, these can be reset in the Preferences by clicking
'Load defaults'.

It is strongly recommended to set the default control point detector to
Hugin's CPFind.  It is the only control point generator endorsed by Hugin.
Third-party generators may be compatible with the plug-in architecture.

COMPILING
There are some changes to Hugin 2014.0 which affects the compiling:
* An OpenMP capable C++ compiler is strongly recommended. Without an OpenMP capable compiler Hugin and all tools will only be single threaded.
* Hugin started using C++11 features. If your compiler does not support them it will using the boost library instead (see README for more detail).

Changes to dependencies
* lensfun library and all dependencies of this lib are no longer needed.
* sqlite3 is now needed for camera and lens database
* libfftw3 is optional, but recommended. With libfftw3 the finetune feature and align_image_stack show a significant speed up.
* libvigra >=1.9 is now required (the internal old vigra library has been removed from Hugins source code). Check that libvigra is compiled with TIF, JPEG, PNG and *OpenEXR* support (at least the OpenEXR support is by default optional and needs to be activated explicitly during compiling of libvigra)

Next steps
* Please test the release and report bugs and quirks.
* This release adds some new strings. So translators please update your translation files.

Moving images in the stack?

Hi, 

 the pictures that I load into hugin for panoramas are not named sequentially so I would load them in and then use "move image up/down" arrows in the interface to put them in the correct order.  I can't see how to do that in the new version.  Any help is greatly appreciated!

thanks,
-Annette

leveling horizon commandline

I have a script that automates the creation of 360 degr. panoramic images.
There are differences in the output with the leveling of the horizon with autooptimiser from hugin 2013 and from hugin 2014 when i run autooptimiser -l from the commandline.
Hugin 2013 gets the right result, hugin 2014 doesn't. With hugin 2014 i can't get it working properly.
See attached images.

Looking for tutorial on making a 3-D image of an object.

I am looking for a tutorial on how to make a 3-D image of an object from 2-D photos. I have searched the Interent and I only find references to Hugin and panoramas. 

I don't think this is the same as a panorama, as a panorama is a 360 degree view with the camera rotating on the vertical axis. Instead, I want the object to be stationary, and to be able to "walk around" the object to see all the sides.

Can Hugin do this, or is there another piece of software that can accomplish this task? Any recommendations?

Thanks,

Mark

It doesn't stop Hugin from displaying and working, but what's up with

automatically create mk file

I just updated hugin to Pre-Release 2014.1.0.ef7e9d77560a.  In the past when I created an pano and saved the pto file hugin would also save a .mk file.  This version doesn't appear to be saving the .mk file at the same time, was that feature removed?  I looked through the preferences but didn't see where it could be turned on.

Thanks,
Kevin
