Feed glomap output camera positions to colmap global bundle adjustment? #83

Closed arcman7 closed 9 hours ago

Question - can we feed the output camera positions from glomap to colmap mapper / global bundle adjustment process?

If so, are there any potential pitfalls to doing this?

Hi, it should be possible to do this by directly calling colmap bundle_adjuster --input_path INPUT_DIR --output_path OUTPUT_DIR. However, I am not very sure how much of the benefit you will see from this option, since GLOMAP contains several rounds of bundle adjustment as well.

Yeah - tried that, and you're right. Not much difference, but sometimes it helps a little.
