Zed X Blurry/Soft Image Quality

Hardware ZED X
21

It seems that NVIDIA reintroduced a broken version of the library libnvisppg.so when updating the device with sudo apt upgrade or other methods.

You can install the working library by unpacking the .deb and data.tar.gz and then copy /data/tmp/R36.4.3/libnvisppg.so to /usr/lib/aarch64-linux-gnu/tegra/libnvisppg.so

First of all download the ZED X Driver installer from the download page.

sudo apt install nginx
ar x stereolabs-zedbox-mini_1.3.1-SL-MAX9296-all-ZEDBOX-MINI-L4T36.4.0_arm64.deb
tar xvf data.tar.xz
sudo cp ./tmp/R36.4.3/libnvisppg.so /usr/lib/aarch64-linux-gnu/tegra/libnvisppg.so

Then reboot.

This should solve the problem.

Hi @Myzhar ,
I was also getting blurry images from the ZED X Mini camera. I am using the ros2 wrapper running on a Jetson Orin AGX. I applied your solution - it succeeded in getting rid of the blurry images, but now the images are very grainy. Is there a solution to get rid of the noise? I tried playing around with the denoising paramter but it did not have a very huge impact on the overall result.

Hi @Betgov
Welcome to the Stereolabs community.

With the patch applied you can use the video setting DENOISING to tune this behavior.

You can test it with ZED Explorer to find the value that fulfills your requirements.
