I am using the Zed X, Capture Card Duo, and Jetson Orin NX.
I performed the installation according to the guides, the ZED SDK version is 4.2.5. After turning on the ZED Explorer, an image with graphical artifacts appears on the screen (green dots on the image). I tried changing the camera settings in the app, but it only slightly reduced the artifacts.
I also noticed that in about half of the cases, after closing ZED Explorer and turning on ZED Depth Viewer, the image disappears. When using the ZED_Explorer --all command, the camera list says that the camera is not available.
What is the reason for this problems?
Hi @Oweifh
Welcome to the Stereolabs community.
What version fo the Jetpack are you running on the Jetson?
Probably the software is not closed correctly. Are you killing it by Ctrl+X in the terminal?
If the software is not correctly closed the GMSL2 connection remains in a pending status and then the camera is no longer reachable.
There is a timeout of about 20 seconds after which the camera will be available again.
This long period of waiting is fixed by NVIDIA and it cannot be changed.
You can immediately recover the connection by calling the command sudo service zed-x_daemon which forces a ZED X Driver reset by unloading and loading it again.
Hi
I’m using Jetpack 6.1 [L4T 36.4.0] and stereolabs-zedlink-duo 1.2.2 L4T36.4.0 driver.
I always closed applications using the command Ctrl+C in terminal, but sometimes this does not help.
What should I do with graphic artifacts? Is this an issue with the camera setup or with the camera/capture card?
This issue affects Jetpack versions 6.1 and 6.2 due to a bug introduced by NVIDIA in the Argus library. The denoiser filter no longer allows for adjustment of its strength, resulting in excessively blurred images when activated. Consequently, we have disabled the filter by default, leading to the current visual effect you observe.
We have reported this issue to NVIDIA, and they have confirmed they can replicate the problem, but they have not yet provided a fix. I suggest downgrading to Jetpack 6.0 while we await a resolution from NVIDIA.
Please tell me, do I understand correctly that for firmware via the ZED SDK for version 6.0, I need to use a different version of Ubuntu on the host machine?
