Unable to Generate Depths for Resolution Level 0 with GPU Docker

[Vivek]

We are creating DepthMaps for Resolution Level 0 with CPU-Docker. It works well and generate detailed depth maps but has performance issue with an increase in the number of images.

As an alternate option, tried to generate Depths with Docker-GPU and it completed this step w/o generating single depthmaps. When had change the resolution level to 1, it generates depth maps as expected.

Can you suggest, why there is different behavior for GPU and CPU Docker?

[Saijin_Naib]

They’re completely different pipelines, so they do behave differently at the moment. We are looking into it, and I hope will be able to make them behave more consistently over time.

What do you mean by Resolution Level 0 and Resolution Level 1?

What are your full processing parameters like?

[Vivek]

The following is the command that I trigger with ODM Container:

docker exec python3 /code/run.py --max-concurrency 8 --project-path /datasets project --feature-quality ultra --pc-quality ultra --mesh-octree-depth 13 --end-with openmvs

And this invoke, OpemMVS stage wherein following command is invoked:

“/code/SuperBuild/install/bin/OpenMVS/DensifyPointCloud “/datasets/project/opensfm/undistorted/openmvs/scene.mvs” --resolution-level --min-resolution 9735 --max-resolution 19470 --max-threads 8 --number-views-fuse 2 -w “/datasets/project/opensfm/undistorted/openmvs/depthmaps” -v 0 --geometric-iters 0”

When the resolution level value is set to 1, it works but it didn’t work with resolution level 0.

What is your console log output for the failed/passing tests?

[Vivek]

Since the /datasets/project/opensfm/undistorted/openmvs/depthmaps folder is empty it fails at next step

[Vivek]

Do you need any more information?

@Piero, Can you please suggest here? We are in the last stages of making ODM operational for heavy Stereo Images and this particular issue makes it very a slow and eventually expensive solution.

Any update here?

@Vivek

We are in the last stages of making ODM operational for heavy Stereo Images and this particular issue makes it very a slow and eventually expensive solution.

That sounds like an opportunity to fund core development, and in this case since Piero is fully booked the best way forward would be to find someone contribute a solution:

Adding more information - DensifyPointCloud step fails while calling SceneDensify.cpp script at line 1750:

data.events.AddEvent(new EVTProcessImage(0));
