OdmExtractUtm produces -nan coordinate

I keep running running into the same issue no matter what image set I try to use. Used geotagged images, used none geotagged.. same error. Please could someone suggest what it is that I ma doing wrong or need to change. many thanks

Hi @capedrone, it's hard to say what the problem could be. Could you share the images you are using so that we can try to reproduce it?

[capedrone]

Hi Pierotofy: here are just 8 images.. the full set has 89.. please test, I am re-running program now with the same 8 images... https://www.dropbox.com/sh/dxrdm1ydqpxqpav/AAC3mvZsZm0kJapNJD6QF-Gra?dl=0

Hope the dropbox link work

Kind Regards

The problem seems to be caused by a fault in the odm_extract_utm program, which generates a Z coordinate with the value -nan:

cat odm_georeferencing/coords.txt

WGS84 UTM 34S
269069 6257079
-0.8049886768 -8.296736724 0

16.17286643 -21.0271387 0
-31.41965067 14.37799052 0

The program seems to hang-up with:

Error in OdmExtractUtm:
Failed to transform coordinates

I will need to dig into this further. I will post an update when I know more. Thank you for reporting the problem!

[pierotofy]

Still need to look into this, sorry for the delay.

[pierotofy]

After applying the changes in https://github.com/OpenDroneMap/OpenDroneMap/pull/596 I was able to process the dataset correctly.

It was a fault in the odm_utmextract module. Thank you for reporting the issue! I don't think we would have caught it without your help.

As soon as the pull request is merged into OpenDroneMap, wait a day and do a docker pull opendronemap/node-opendronemap, then restart WebODM.

Fantastic, thanks for the update 👍
