The 3.3.1 patch version has been released! See here https://www.stereolabs.com/developers/release/

Here are the release notes :


The ZED SDK patch 3.3.1 fixed bugs reported by users to make the ZED SDK even more useful. Some modules have been reworked to provide a better experience. We also improved our documentation to make it denser and easier to understand. Wrappers and their sample have been updated to better reflect SDK capabilities.

  • Updated Depth Quality filtering to remove the quantification effect in some cases.
  • Fixed an issue in Spatial Mapping module which was leading to aborting the process.
  • Improved object tracking process runtime.
  • Reduced object detection flickering.
  • SDK installation now follows Windows rules about program drive.


  • ZEDfu no longer stops in a random way.
