[gentoo-user] Hugin panoramic picture and auto control points.

[gentoo-user] Hugin panoramic picture and auto control points.

[Dale]

Howdy,

I been using Hugin to create panoramic pictures for years.  The
automatic create control point button never worked.  It always spit out
a error about a tool missing so I did it manually.  Time consuming to
say the least.  I recently took a few pictures and got tired of spending
all night going through pictures manually setting control points.  I
decided to try and figure out how to fix it since all the programs and
commands should be installed.  I went to File, Preferences and then
clicked on the Control Point Detectors tab in the new window.  If you
have autopano-sift-C installed, it should be the default.  Highlight it
and then click Edit. Find Program and then click the Choose button.  The
correct setting and path is /usr/bin/autopano-sift-c.  The default I
think was autopano-noop.sh or autopano-noop.  When I googled, I couldn't
find that command anywhere so no idea why that is the default setting. 
It took me a while to figure out where that setting was.  Google wasn't
much help.  Once you have that set up, you should be able to add
pictures and then tell it to Create Control Points and it work. 

I don't know how few use this program on this list but since I get a lot
of help here, I wanted to post this just in case it will help someone
who does use this and has the same problem I had with having to do it
manually.  Trust me, it is much faster and it does a awesome job so
far.  What normally would take me all night only took a few minutes with
the auto tool working plus it creates a lot more control points. 

Hope this helps someone.  Pictures makes memories.  :-D  I may post a
link to some at some point.

Hi Dale,

Hugin has a USE-flag for SIFT which pulls autopano-sift-C as a 
dependency: sift? ( media-gfx/autopano-sift-C ). The SIFT algorithm used 
to be patented [1] which could be a possible reason why the dependency 
was not enabled by default, though you might have to ask the maintainer 
for that. The patent is expired as of this year, so there is probably 
little reason to not enable the USE flag for you. "autopano-noop" is an 
obsolete wrapper [2] for autopano-sift-C which might be an artifact from 
an earlier hugin version upgrade.
Anyway, good that you got it to work.

Sincerely,
Meik

I already got it working.  I was posting about how to get it to work. 
Hopefully, if someone googles it, they will find this thread and be able
to follow how to set it up and it work. 

Since I installed this so long ago, it likely held the old defaults over
from the past.  It may work on new installs.  Oh, I already had the sift
USE flag enabled.  Still, the defaults didn't work. 

Interesting to know some history about this tho.  May explain why it was
the way it was.

Additional info.  Since I had a backup of the original configuration, I
decided to give the new defaults a test drive.  I clicked the Load
Defaults button and it changed about everything.  The old settings
seemed to have left completely.  Keep in mind, this install goes back
YEARS.  It may be well over a decade old as far as configs go.  I copied
/home over from my previous system.  The new default is Hugin's CPfind. 
I've taken a few panoramic pictures and give it a go.  At first, I did a
couple control points manually for each set if pics.  Then on the last
two sets, I loaded the images and just hit Create Control Points and let
'er go.  After clicking all the other things and telling it to stitch,
they turned out awesome.  I looked for errors in the picture but I
couldn't find any.  Since my pics were mostly of trees, I looked for
trees that were bent or out of line in some way.  I couldn't find
anything wrong.  Darn software does a awesome job.  :-D 

Only downside, the resulting files are pretty large even when I scale
them down a bit.  Most image hosting sites cut off file sizes and mine
are to big.  Gotta find a solution for that problem, new image site
maybe?? 

Thanks for the reply Meik.  It got me to test some really new settings. 
Something I should have done a LONG time ago.
