GLOMAP Reconstruction Fails with COLMAP's `--image_list_path` Option #81

Closed alejandrofontan closed 2 weeks ago

alejandrofontan commented 2 weeks ago

When using GLOMAP mapper to reconstruct a map from a database created with COLMAP that utilizes the --image_list_path option to filter images, the reconstruction produces completely incorrect results. 

colmap feature_extractor \
    --database_path ${database} \
    --image_path ${rgb_path} \
    --image_list_path ${colmap_image_list} \

However, when using GLOMAP mapper on a database created with COLMAP without that option, using all images in a folder, it works great.

Could it be that GLOMAP is confusing the images specified in --image_list_path with all the images in the --image_path directory?

Do you know what might be causing this issue, or do you have any ideas on how I can make it work?

Thanks!

Hi, thanks for your interest. Can you be more specific on which command you call GLOMAP? GLOMAP should only utilize images recorded in the database.db file, and if the database file originally contains all images, then it might be wrong. The --image_path is only used for extracting colors in GLOMAP.

Thanks for your comment; you're right. Using --image_list_path to filter the images when creating the COLMAP database worked. The issue was somewhere else. I tried providing the calibration in FULL_OPENCV format, which isn't supported by PoseLib #82. That was causing GLOMAP to fail.

I appreciate your help!
