Split-Merge Problems

[hmrbcnto]

I tried out the Split-Merge pipeline on one device since it seemed like the best approach for particularly large datasets, but I’m confused as to how to view the output.

When running the regular OpenDroneMap image from docker on one dataset without splitting it, I get a bunch of .obj, .vec, and other files as output. The terminal also prints out ODM’s logo after processing.

But when I ran the split-merge method with the following command:

docker run -it --rm
-v “/home/explosion/Desktop/ODM_Test/dronedata_test_100overlap/whole:/code/images”
-v “/home/explosion/Desktop/ODM_Test/dronedata_test_100overlap/whole:/code/odm_orthophoto”
-v “/home/explosion/Desktop/ODM_Test/dronedata_test_100overlap/whole:/code/odm_texturing”
opendronemap/odm --split 200 --split-overlap 100

it runs for a bit over an hour, then ends with the following messages on the terminal:

[INFO] Aligning submodels…

But when I check the folders, there aren’t any output files. Is there something I’m doing wrong? The dataset is 621 images by the way.

Thank you!

Try to use ODM version 2.0.0

Thank you! I’ve managed to get it to run using the command from dockerhub where I assign an additional two volumes for input and output. Split-merge successfully finished for me, but my output was only two files in tiff format. Is that the expected output?

[Zzyf]

try
docker run -ti --rm -v /my/project:/datasets/code opendronemap/odm --project-path /datasets --split 400 --split-overlap 100

I’ve tried running that command, but I experience the same thing as the first post. It says ‘Aligning submodels’ then it exits

[Zzyf]

docker run -ti --rm -v /my/project:/datasets/code opendronemap/odm:2.0.0 --project-path /datasets --split 400 --split-overlap 100
did you add the version?

Yep!
