Covariance field empty

[ishaniis]

Hello @fabianschenk : I'm just getting started with opensfm. When I checked my reconstruction.json, the covariance field was empty for the data/berlin. How can I enable covariance or get the computed covariance field explicitly?

Also, can you guide me on how I can check or deduce something like a confidence score over the feature descriptors, which feature descriptor is credential and which is not? Is there any utility within the API that I could use to get that?

Thanks in advance for your help.

Hi @ishaniis.

As you might have seen, development of OpenSfM has significantly slowed down in recent months because we have other priorities now. I don't have time to help you much but I think changing the settings here might do the trick: https://github.com/mapillary/OpenSfM/blob/34a8ec8b0847c156d7ad2e5a4b2a730904a48325/opensfm/src/bundle/src/bundle_adjuster.cc#L35

Best, Fabian

Thanks for your reply & help, Fabian.

I did that, it gives out a residual error.

Best, Ishan
