Auto Exposure is not working well. (Zed X One 4K)

chungshs · May 20, 2024, 7:11am

Hello,

I am reaching out for assistance with an issue we are experiencing with the Zed X One 4K cameras. We have purchased both the GS and 4K versions of the Zed X One. While the GS version produces accurate images outdoors, the 4K version does not. It appears there may be a problem with the minimum exposure time being too low or possibly a driver issue. We have tested two separate Zed X One 4K cameras, which leads me to believe this is not an isolated product defect. Could you please investigate this matter.

Hi @chungshs
Welcome to the Stereolabs community.

What is the version of the GMSL2 driver that you are using with your cameras?

Thanks for replying.
I used “stereolabs-zedone4k_1.0.1-ZED-LINK-DUO-L4T35.4.1_arm64.deb”

Please try to install this new drive v1.0.5.

stereolabs-zedone4k_1.0.5-ZED-LINK-DUO-L4T35.4.1_arm64.deb (752.8 KB)

We will soon update the download page to direct retrieve it from the website.

Oh Thanks It works well
Is there any plan to use camera chip which has led flickering mitigation?

You can set the Anti Banding feature.
Here’s an example:

github.com

stereolabs/zedxone-ros2/blob/main/zedxone_components/src/zedxone_camera/src/zedxone_camera_component.cpp#L1190C1-L1197C24


      
          // ----> Anti Banding
          res = _cam->setAEAntiBanding(_aeAntiBanding);
          if (res != 0) {
            RCLCPP_WARN(get_logger(), "Failed to set AE Anti Banding");
          } else {
            DEBUG_STREAM_CONTROLS("Set AE Anti Banding OK: " << static_cast<int>(_aeAntiBanding));
          }
          // <---- Anti Banding
