Recover camera poses ERROR running `python img2poses.py $your-images-folder`

[asbeg]

Hello i am trying to run python img2poses.py $your-images-folder to get camera poses for training (Neural Radiance Fields) and get this ERROR. Hardware: MacOS M1 Can you explain what the problem might be and how to fix it

Need to run COLMAP
[option_manager.cc:811] Check failed: ExistsDir(*image_path)

Hi @asbeg, have you figured it out?

hi, same error, have you solved it?

I had the same error, I fixed it by manually running the colmap command in the error to see what was wrong. In my case I tried running python3 imgs2poses.py testscene/images/

and got an error message ending with subprocess.CalledProcessError: Command '['colmap', 'feature_extractor', '--database_path', 'testscene/images/database.db', '--image_path', 'testscene/images/images', '--ImageReader.single_camera', '1']' returned non-zero exit status 1. So I copied each piece out of that list and tried running the command manually from my terminal: colmap feature_extractor --database_path testscene/images/database.db --image_path testscene/images/images --ImageReader.single_camera 1

Which then gave this error:

[option_manager.cc:748] Check failed: ExistsDir(*image_path)
ERROR: Invalid options provided.

It was then that I realized I had just put in the directory wrong... it should have been

python3 imgs2poses.py testscene/, as you're supposed to give it main directory for your scene.

I don't know if for you theimgs_nerf directory is where your images are actually held, but if it is you should change that directory to images and then just give the imgs2poses script the ProjectTest directory.

A very silly mistake on my part so I don't know if it's the same problem on your end, but hopefully running the colmap command that's causing the error like I did might shed some light on what's going wrong.
