Quality degradation with a stream generated by a Jetson Nano (4.1.3)?

Hello,

I am having some issues with the quality of 3D body tracking on an interactive project using a Zed2i camera with a Jetson Nano.

There is a lot of jitter and detection loss.

The area is huge and there could be a lot of people.

I have tried many different post-processing approaches to smooth the result, but with no success.

Due to an error made by the integrator, I had to install a Jetson Nano (running SDK 4.1.3) instead of using fibre optic.

When I set up the Jetson and checked the feed with the Explorer, I noticed that we are limited to 1920x1080 resolution and H.264 lossy compression.

So, do you think the detection quality are impacted by the Jetson’s attempt to stream the feed, which implies some quality degradation and jitter compared to a setup where the camera is connected via USB?

Thanks

Hi,

That’s possible that the quality is degraded if the image quality decreases because of the stream (due to lossy encoding) or if the capture frame rate is lower because the Jetson nano is not powerful enough to capture at full FPS.

Hey Benjamin,

Thanks for the feedback and the confirmation.

I have been struggling with this project for a long time to achieve consistent and correct results.

The Jetson Nano is really at the edge of this performance, so it’s no mystery why the detection is so random.

I will contact the hardware integrator to resolve this issue with a proper fiber connection.
