Error in ODM meshing cell - pdal pipeline


Hi All,

I was processing images using ODM from native install… I am using the latest version pulled from github. I ran into this error at ODM_meshing stage:

This was caused directly by

    r = call_item.fn(*call_item.args, **call_item.kwargs)

  File "/code/opendm/", line 34, in run
    raise Exception("Child returned {}".format(retcode))
Exception: Child returned 139

I also tried docker image(latest)…which gave the same error as above.

The command I gave was -

docker run -it --rm -v “/home/garlac/ODM_dev_version/ODMprojects/Docker_projects/MLA_3nov_v1:/datasets/code” opendronemap/opendronemap --mesh-point-weight 0 --force-ccd 12.8333 --texturing-nadir-weight 32 --smvs-output-scale 1 --ignore-gsd --orthophoto-resolution 2.57 --mesh-size 1000000 --time --mesh-octree-depth 12 --opensfm-depthmap-method “BRUTE_FORCE” --crop 0 --resize-to -1 --project-path ‘/datasets’

Earlier I didnt get such an error when --use-3dmesh parameter was used!!

Is it a bug or some other problem.?

Thank you.


Hey @garlac :hand: Does it fail for with every dataset or just certain ones?


I am running it on two other datasets, will let you know once it gets completed.


Hi @pierotofy,

It is failing on only certain datasets…not sure of the reason!

The images of one such dataset where it failed is shared in below link -
