Hi,

I've build colmap on a Debian-Linux machine following the instructions on : https://colmap.github.io/install.html#linux .
Colmap now appears in the menu.
Opening the "south-building" dataset and pressing the reconstruction button the log-screen starts with:

!!!!!!!!

==============================================================================
Loading database
==============================================================================

Loading cameras... 1 in 0,000s
Loading matches... 1887 in 0,016s
Loading images... 128 in 0,065s (connected 128)
Building scene graph... in 0,150s (ignored 0)

Elapsed time: 0,004 [minutes]

!!!!!!!!

and after some 3 minutes ends with:

!!!!!!!!

Elapsed time: 3,078 [minutes]

!!!!!!!!

In ther mean time a lot of messages have passed along.

Hereafter I can move around the model, take snapshots and even a film.

When I start a new project in a different directory, with the same images, and press "Extract" in the "Feature extraction" screen colmap dies.
This is also the case when I start a completely new project with different images.

What am I doing wrong or what can I do to fix this ?

Regards,

René.

Cannot find the location of num_params == camera.NumParams() (8 vs. 4)
How can I correct this ?

Are you using the GUI or from the command-line? Are you manually specifying camera parameters?

Yes, I use the GUI.
In the "Feature extraction" I do not see camera specification.
"Parameters from EXIF" is marked.

Greets,

René.

When changing the image folder, do you specify a new database or reuse the old one? I cannot reproduce the issue you describe, but maybe I misunderstand.

In both cases Colmap shuts down.

Could you run the feature extractor from the command line as ``colmap feature_extractor –image_path /media/rene/25a53c3c-4d12-4f7b-a33c-9abc481f4c89/Downloads/colmap_datasets/potje_bloemen_1/ --datbase_path /media/rene/25a53c3c-4d12-4f7b-a33c-9abc481f4c89/Downloads/colmap_datasets/potje_bloemen_1/potje_bloemen_1_1.db`` and reply with the full output?

Seems like you don’t have a functioning GPU on your machine. Try to run the CPU based feature extraction / matching.

You are my hero.
I would never have found this solution.
Was not aware that GPU means Graphical Processing Unit in contrary to Central Processing Unit.

Thank you for your extensive help.

Colmap now does what it was designed for. Great job.

Greetings,

René.
