Feature extraction crashes

[w.wi...@gmail.com]

Hi everyone,

I am using COLMAP-3-5-windows-no-cuda and I am trying to extract features from gerrard-hall dataset using following commands:

.\bin\colmap database_creator --database_path .\gerrard-hall\database.db
.\bin\colmap feature_extractor --database_path .\gerrard-hall\database.db --image_path .\gerrard-hall\images  --SiftExtraction.use_gpu 0

The first command works, but when I execute the second one the execution starts but stops without any further output.

When I executed that command earlier, I got following error message: "ERROR: Failed to read image file format."

Then I tried it with the same data within the GUI: It worked

After that I executed the command in the command line again and got following message for all images: SKIP: Features for image already extracted.

Therefore I deleted the database file and the execution crashes as described above.

The problem is, that I want to use the command line interface to call it from another application.

Can anyone give me a hint what I can do to make it run from command line?

Kind regards,

Wolfgang

Now I run it again with the Windows GUI and it had the same problem (images could not be .

Additionally I had to replace the image folder with the one from the dataset zip file because before the application crashed without any error message.

I am really sorry but the software does not work on windows (on linux it does, but I need it on windows) :(
