PLY ERROR: fread() failed

ODM

Hi,
I have a medium dataset of ~360 images originally from Mavic Air but I resized them to 1024 due to lack of enough RAM.

Now I get stuck at PoissonRecon:

[DEBUG] running /code/SuperBuild/src/PoissonRecon/Bin/Linux/PoissonRecon --in
/datasets/code/smvs/smvs_dense_point_cloud.ply --out /datasets/code/odm_meshing/
odm_mesh.dirty.ply --depth 9 --pointWeight 4 --samplesPerNode 1.0 --threads 6 –
linearFit
PLY ERROR: fread() failed – aborting.
Traceback (most recent call last):
File “/code/run.py”, line 47, in
plasm.execute(niter=1)
File “/code/scripts/odm_meshing.py”, line 70, in process
verbose=self.params.verbose)
File “/code/opendm/mesh.py”, line 127, in screened_poisson_reconstruction
‘{verbose}’.format(**poissonReconArgs))
File “/code/opendm/system.py”, line 34, in run
raise Exception(“Child returned {}”.format(retcode))
Exception: Child returned 1

Any idea what went wrong this time?
Thanks

The problem is likely further up in the pipeline, do you have a copy of the full task output? PoissonRecon failed probably because the smvs_dense_point_cloud.ply file has some issues.

Hi,
Sorry for a late reply.

I uploaded the whole set → [deleted]

If it’s too big for you and you are looking for specific files just let me know…

Thanks

Only the task output is needed. You copy/pasted part of it. Having a copy of the full log would help.

Here is the current one, but perhaps you’d like to see the whole process starting from scratch?

Yeah from scratch would help :slight_smile:

log uploaded → log.txt - Google Drive

Mm, beside a few of the camera views being skipped, I don’t see much out of the ordinary.

I would recommend trying to examine the PLY file stored in the smvs directory for clues as to what might have gone wrong (does it open in MeshLab?) or process the dataset with --use-opensfm-dense.
