autopano null value at MultiMatch.LoadKeysets

autopano reads in text files with dot posistions, not images.
Anyway, it should output a comprehensible error message rather than a stack trace.

Thanks! I think I'm in a bit over my head, then. Can you point me to a
tutorial? ;)

BIP!!!

I got the same error, from an invocation of autopano-sift by Hugin.

In the package autopano-sift (2.4-0ubuntu8), the executable is called autopano. Using the default settings, Hugin (0.7.0~svn3191+beta5-1ubuntu1) expects it to be called autopano-sift. After changing Hugin's preferences, it calls:

autopano --maxmatches 20 /tmp/ap_resjyB4Iq "/home/sybren/2008/20080926-Utrecht/hdr1/jpeg/hdr1-1.jpg" "/home/sybren/2008/20080926-Utrecht/hdr1/jpeg/hdr1-2.jpg" "/home/sybren/2008/20080926-Utrecht/hdr1/jpeg/hdr1-3.jpg" "/home/sybren/2008/20080926-Utrecht/hdr1/jpeg/hdr1-4.jpg" "/home/sybren/2008/20080926-Utrecht/hdr1/jpeg/hdr1-5.jpg" "/home/sybren/2008/20080926-Utrecht/hdr1/jpeg/hdr1-6.jpg" "/home/sybren/2008/20080926-Utrecht/hdr1/jpeg/hdr1-7.jpg"

The program output reads:

autopano-sift, Automatic panorama generation program

I would expect the default Hugin preferences to simply work with the Ubuntu packages.

I also had this error executing autopano from hugin, looking at the log, but I received a message from Hugin saying the I had to define some matching points between the 2 images.
I defined them, and it was working.

So this error is due to a bad use of autopano.

And about the default value in hugin, I'm waiting for the debian package of final 0.7.0 to make the 'Ubuntu' version of it (renaming autopano-SIFT by default).

I've checked the online help of autopano, and it should be able to resolve automatically the mathcing points.

Will investigate.

Got it!
Correct parameters for autopano-SIFT command in hugin is:
executable: autopano-complete
Parameters: --points %p -o %o %i

Changing package to hugin one

Excellent! I'm currently away from the workstation I use autopano on;
as soon as I have access again, I'll confirm the solution.

Thanks much!

Wating for confirmation that those parameters actually fixe the problem.

I can confirm thar those parameters fixed the problem in ubuntu intrepid i386

This change will be delivered with hugin 7.0 final version

After a ridiculously lengthy delay (I was far from home on business), I
too can confirm this works on 8.10 AMD64.

Thanks guys!

This bug will be closed when bug #285674 will be closed.
Putting back in Confirmed state.

This bug was fixed in the package hugin - 0.7.0-1ubuntu1

---------------
hugin (0.7.0-1ubuntu1) jaunty; urgency=low

  * Closes LP: #285674
  * Closes LP: #162575
    - debian/control: added dependency on autopano-sift
    - debian/patches: added 91_ubuntu-autopano-sift to fix default config
  * debian/control: change build dependency from libwxgtk2.6-dev to
    libwxgtk2.8-dev

hugin (0.7.0-1) experimental; urgency=low

  * New upstream release (Closes: #502721).
  * Depend on both enblend (>= 3.2) and enfuse, now that they are
    available (Closes: #495874).
  * Drop the following patch accordingly:
     - 50_disable_enblend_compression
  * debian/rules:
     - Specify “ChangeLog” in the dh_installchangelogs call since that's a
       proper release and no longer an SVN snapshot.
     - Get rid of the autooptimi{s,z}er renaming hack, fixed upstream.

hugin (0.7.0~svn3191+beta5-2) unstable; urgency=low

  * Update README.Debian to reflect the current status of hugin with
    respect to enblend/enfuse. Also point to the following page, which
    will contain uptodate information about the backports for the lenny
    lifetime:
      http://pkg-phototools.alioth.debian.org/lenny.html
  * Add forgotten “tca_correct” binary to debian/hugin-tools.install,
    thanks to Chris Chiappa (Closes: #502104). Another one is
    “matchpoint”, but since it wasn't requested yet, don't touch it at the
    moment.

hugin (0.7.0~svn3191+beta5-1) unstable; urgency=low

  * New upstream release candidate: 0.7.0_beta5. The exact revision wasn't
    specified but that's mostly the same as svn r3191.
  * Adjust dependencies, thanks to several reporters, and especially to
    Andreas Metzler for the checks on enblend and the pointers:
     - Add make to hugin's Depends (Closes: #492469).
     - Move enblend from hugin-tools's Recommends to hugin's Depends, as
       it is now a requirement (Closes: #394647, #491539).
     - Also add libimage-exiftool-perl since upstream specifies that the
       the exiftool binary (from the Image::ExifTool Perl module) is
       needed.
     - Version the Build-Depends on libexiv2-dev: “>= 0.12”. With former
       versions, an FTBFS is triggered due to undefined references to
       Jpeg-related functions (Closes: #491335).
  * Add autopano-sift-c as alternative to autopano-sift to the suggested
    packages. As a reminder, patent issues prevent the inclusion of those
    packages in Debian.
  * Fix manpage mismatch: /usr/bin/autooptimizer versus autooptimizer(1),
    (spotted by Julien Valroff, thanks):
     - debian/rules: Copy generated doc/autooptimizer.1 into
       doc/autooptimiser.1, and remember it for cleanup.
     - debian/hugin-tools.manpages: Replace the z version with the s one.
  * Disable enblend compression, since Debian has enblend 3.0 for now and
    this option would require enblend 3.1 or a CVS snapshot. That means
    that the compression setting is going to be silently ignored for now,
    thanks to a quick patch by Steve Cotton (Closes: #491227, #491562):
     - 50_disable_enblend_compression: Do not call enblend with
       a “--compression” argument.
  * Add a README.Debian file to document that some fea...

Agreed, fixed.

Thanks to all involved!
