import features fails

[Charlotte0592]

Thanks for sharing the amaing benchmark! I have some promblems when I run:

python reconstruction_pipeline_aachen_v1_1.py 
    --dataset_path /local/aachen 
    --colmap_path /local/colmap/build/src/exe
    --method_name method

then, it happens:

Traceback (most recent call last):
  File "reconstruction_pipeline_aachen_v1_1.py", line 335, in <module>
    import_features(images, paths, args)
  File "reconstruction_pipeline_aachen_v1_1.py", line 164, in import_features
    cursor.execute("INSERT INTO keypoints(image_id, rows, cols, data) VALUES(?, ?, ?, ?);",
sqlite3.IntegrityError: UNIQUE constraint failed: keypoints.image_id

Does it means there are two or more same keypoints? Could please help me solve this problem?

Can you provide more details on what you are trying to do? How do you obtain the features?

According to Aachen v1.1 dataset, I wrote a images_list.TXT by myself and then used extract.py in R2D2 to extract local features, using the following command:

${PYTHONBIN} extract.py --model my_models/${LOCAL}.pt --images ${DATASETS_PATH}/images_list.txt --min-scale 0.3 --min-size 0 --max-size 9999 --top-k ${KPTS} --tag ${METHOD}

And I want to check whether my algorithm to extract local features is work, so I run

python reconstruction_pipeline_aachen_v1_1.py \
    --dataset_path ${DATASETS_PATH} \
    --colmap_path colmap \
    --method_name ${METHOD}

I want to use only local features to achieve visual localization, so I run this pipeline to obtain the queries' pose, in order to check whether my own algorithm is good. But I ran into the problem as described above. Could you please give some advice?

The error sqlite3.IntegrityError: UNIQUE constraint failed: keypoints.image_id indicates that there are two images with the same image_id. I haven't seen this happening before though. Did you change anything else?
