Description

Hi,
@paulinus

I have achieved my first result from a set of input panoramas with default parameters
feature_min_frames: 16000
feature_process_size: 4000
The result looks quite noisy. I dont know what quality I can expect from OpenSfm. I also dont know what parameters or factors impact the reconstruction quality mostly . Can you give me some advice ? Thanks
