Discussion on colmap

Dear sir, now when I try to run the python lib/colmap/imgs2poses.py -s <source path> with the correct and high-quality images (number is 20), the result is shown as below.

Sparse map created
Finished running COLMAP, see dataset/20240928-224635_scene_kitchen_20/colmap_output.txt for logs
Post-colmap
Cameras 5
Images # 3
Index out of range: ind=8, len(cams)=3
ERROR: the correct camera poses for current points cannot be accessed
Done with imgs2poses

Why it produces such result? Actually I can succeed in completing this process when I use other dataset, including your examples as well as my own customed datasets.

The error caused by running the colmap script is due to low overlap, which can also be found https://github.com/Fyusion/LLFF/issues/36#issuecomment-648018595.

You can first run colmap sparse reconstruction https://colmap.github.io/cli.html# , and then run the script lib/colmap/imgs2poses.py to get poses_bounds.npy.
