Export estimate Colmap intrinsics failed #4

Closed z-x-j closed 10 months ago

z-x-j commented 10 months ago

When I use python api/data/preprocess/export_slow_tv.py --n-proc 16 to export the Colmap intrinsics, I encounter an error. RuntimeError: -> Tried [42, 195, 335, 558, 724] and they all failed!!How should I resolve this?

"I found during debugging that on line 209 of devkits/slow_tv.py, subprocess.run cannot run." code:
subprocess.run([ 'colmap', 'feature_extractor', '--ImageReader.single_camera', '1', # Same cam for whole sequence. '--database_path', db_path, '--image_path', img_dir, ])

Hi!

Sometimes this can simply be due to the feature matching failing. You can try changing the random seeds used to select the sub-sequence processed by Colmap. Does it fail on all sequences, or just on some?

The other thing I would recommend is running the commands yourself in the command line to check the output in the terminal.

Kind regards, Jaime

I tried random seeds within the range of 1 to 1000 with intervals of 10, but it failed. Is it because I haven't installed COLMAP? I'm looking forward to your response.

In order to run the Colmap you have to have installed it first. You can find the instructions here

"Thank you for your guidance; I solved the issue using the 'sudo apt install colmap' command. Thank you."
