COLMAP GUI finds poses while nerfstudio COLMAP settings does not?

[abrahamezzeddine]

Describe the bug
COLMAP via NerfStudio does not find enough poses although COLMAP GUI finds the poses correctly. Using sequential for this.

To Reproduce
Steps to reproduce the behavior:Perform ns preprocess data with COLMAP with sequential image frames. Fails.
Perform automatic reconstruction sparse data with COLMAP with high or low quality and sequential image frames. Successful.

Expected behavior
The nerfstudio preprocess data should pass accordingly, just like COLMAP GUI should do.

Hi! The pose matching process in COLMAP is random, so you may need to try a few more times for it to match successfully.

Quite a time consuming process to be honest to do such guessing game... Especially for large datasets...

Currently using COLMAP GUI with high success rate actually. Then I import them to nerfstudio via this command below;

ns-process-data images --verbose --skip-colmap --colmap-model-path sparse/0 --num-downscales x --data folder/images --output-dir folder/. There is no documenation for this so I am just guessing this is how nerfstudio would import a complete model. Anything else that I might have overlooked with this command?

I need however to create two new folders, "sparse" and "0" and export the COLMAP model into folder 0 in order for nerfstudio to detect the model.
