insight3d on Arch Linux

I love to shoot photos and everything which is related to photography. Today I have seen a tweet about insight3d and it’s looking really good. What is insight3d? Maybe you have seen photosynth from Microsoft, a tool to generate a 3D model from lots of  photos from the same object but from different points of view. insight3d is a similar tool, but it’s OpenSource and it runs under Linux. Basically it should run, but before it runs there are some issues to solve.

It runs, but it crashes all the time. Maybe someone with more knowledge about opencv can help me on this. But now the steps to compile it under (Arch) Linux.

  • download the linux package from the website and extract it to a folder you want
  • install all dependencies from the repository:
    • pkg-config
    • opencv
    • sdl
    • gtk+-2.0
    • libxml
    • lapack
    • blas
    • OpenGL library
    • ANN (from AUR)
  • download the latest version of siftfeat from http://blogs.oregonstate.edu/hess/code/sift/ and extract the contents to “<insight_dir>/insight3d/sift”. Overwrite the old version included in the insight3d package.
  • edit the included Makefile located at “<insight_dir>/insight3d/” as follows:
    • change ANN_INCLUDE to ANN_INCLUDE= -I/usr/include/ANN/
    • change g++ line to:   g++ $(DEBUG) -o insight *.o `pkg-config –libs opencv libxml-2.0 sdl gtk+-2.0` ./sift/lib/libfeat.a $(AGARLIB) -llapack -lblas -lGL -lGLU ./sba/libsba.a /usr/lib/libANN.a
  • if you are on x86_64 then you have to change into the directory “<insight_dir>/insight3d/sba/” and run “make clean” and “make”, because the library included there is for the i386 architecture
  • after doing all the steps, go to the “<insight_dir>/insight3d/” directory, and execute “make”
  • if compilation finished then you can run insight3d with “./insight3d” (or “./insight” if you compiled the SVN version

And now the problem about the crash:

Starting the application works and also loading the photos, but doing the second step according to the tutorial (PDF), and try to match the photos it crashes right after the matching with the following error:

$ ./insight
insight3d 0.3.2, 2007-2009

Aborted

Is there anybody out there which can give me a hint why insight crashes? I can see that there is an error because an assertion failed, but the photos are from the example directory of insight3d and should work. Any hint on this?

Starting my own small photo project

8 days ago I have started my own (small) photo project. I will try to shoot one photo each day between 5pm-6pm (UTC + 01:00) from the sky above me. One week is over and I have managed it so far to shot the photos as I said. You can follow my project here: http://365lookouts.wordpress.com

Normally I upload the picture at the same evening, but sometimes it isn’t possible and I will upload it the other day. Here is my latest shot:

Doing nearly everything for a good photo

As you already know I’m shooting photos during my spare time. Last weekend I was on a photo tour with a friend and tried to shoot some good photos. Sadyl there weren’t such great things to photograph, so the final result of the photos was very sad. Nevertheless here are two photos which I can show:


And sometimes it looks like this while you are shooting a photo and hopefully don’t fall into the water 😉

Doing more with my DSLR

As you can see in my Photo section I’m doing a lot of photography. Now I have began a new way to shot photos to let the photos move. Like everywhere on the web you can find those timelapse videos which are mostly generated from photos. It’s just the beginning and I’m very new to this kind of  photography, but I have already generated two timelapses.

Have fun watching it. Maybe I will made a short tutorial how you can do those timelapses under (Arch) Linux.

CEWE photobook software for Linux

I will write this post in German, because CEWE is one of the biggest (maybe the biggest, don’t know exactly) photo service in Germany. I think, that this information isn’t really important to any other country. Maybe a short example how important this company is: CEWE handles the photo service of Amazon (Germany), MediaMarkt, dm and other big shops and  supermarkets in Germany.

Short summary: CEWE released their photo book software for Linux.

So, dann werd ich jetzt mal in Deutsch weiterschreiben. Ich hab vor längerer Zeit die Pressemeldung von CEWE gelesen, dass sie an der Entwicklung einer Linux-Version sind, nur leider war kein genauer Termin angegeben. Mittlerweile wurde sie freigegeben und steht zum Download bereit. Mehr oder weniger unbemerkt von der breiteren Masse, da die meisten Händler die Linux-Version nicht auf ihrer Webseite verlinken, sondern direkt nur die Windows-Version anbieten. Dabei findet man auf der Downloadseite (von CEWE direkt) für fast jeden Händler auch die Linux-Version.

Ich habe die Software auch ausprobiert, sie lässt sich genauso bedienen wie die Windows-Version und bietet den gleichen Umfang an Hintergründen, Styles, etc. Ein fertiges Fotobuch hab ich noch nicht bestellt, aber das dürfte das kleinste Problem sein und reibungslos funktionieren.

Gut zu sehen, dass Linux von größeren Firmen endlich als Markt angesehen wird. Weiter so!

digikam and 23hq

I have sent an initial patch to the digikam developers for supporting 23hq. They have done some more tweaks to it and some more work to it. Now it’s in their CVS and it works flawlessly. So, if you are using 23hq and digikam as your photo management software you can upload your pictures directly from digikam to 23hq now.  😀

Thanks to Luka Renko who has done the work after my initial patch.
