ZED SDK 0.9.3 Brings Performance Improvements and More

We are excited to announce the release of ZED SDK version 0.9.3! This new update of the ZED SDK brings significant performance and usability improvements, along with support for our new factory calibration technology.

The 0.9.3 release includes the following improvements:

  • Significant performance improvement on PC, Tegra K1 and X1 mobile/embedded system-on-a-chip
  • General usability improvements, including a background process for self-calibration
  • Support for CUDA 7.5
  • Support for ZED new factory calibration technology
  • Improved depth map filtering in saturated areas
  • Many improvements to the ZED tools and samples

New Architecture and Higher Performance

With the number of ZED users growing significantly in the past few months, we’ve been expanding the development team to prepare the release of significant software updates in 2016. We started the year with a brand-new architecture for the ZED SDK that introduces great performance and stability improvements and allows us to push toward shorter release cycles.

The 0.9.3 release brings up to 40% faster depth computation on lower performance graphics chip, including embedded system-on-a-chip such as Tegra K1 or X1. On these platforms, latency has been dramatically reduced when using CPU retrieve functions. These improvements now make the ZED and Tegra one of the most powerful platform for development of embedded computer vision applications.

General Usability Improvements

The new update brings several usability improvements. The initialization of the camera which includes self-calibration is now run as a non-blocking background process. This makes using the ZED much easier as self-calibration does not need to be successful in order to use the camera. If self-calibration is not successful, the SDK will use the default factory calibration.

User interface to record and playback SVO and snapshots has also been improved, and ZED Explorer and Settings App have been merged. The ZED Explorer is now the app to use when you want to adjust your camera controls and calibration settings.

Finally, we’ve also reduced depth flicker in saturated areas by detecting and filtering those areas.

Support for CUDA 7.5

ZED SDK 0.9.3 brings full support for CUDA 7.5 on Windows and Linux, which will simplify the SDK integration in applications using the latest version of CUDA.

New Factory Calibration

Accurate camera calibration is one of the biggest challenges in building a long-range depth sensor. It is very difficult to calibrate a 3D camera with a high accuracy in both the near and far range and in the corners of the picture. At Stereolabs, we’ve been working on improving our calibration process since early 2015, and we now have a brand new stereo calibration process set up at our factory.

This new process brings great improvements in depth accuracy in the far range and in the corners of the image. You can also expect a consistent behavior across all ZED cameras. Cameras shipped after the 1st February 2016 will benefit from this new calibration process. For our other users, we will release a recalibration app with the next update that will let you reach similar results with your ZED.

Download the ZED SDK 0.9.3 Release Today!

ZED SDK 0.9.3 for Windows and Linux is now available for download on our Developer page. Our team is very excited to bring this release as a stepping-stone for the work we have set out for 2016!

    Is it possible to connect and sync multiple ZED cameras for multi view projects?

    I’m trying to install the most recent Zed sdk version (ZED_SDK_Linux_JTX1_v1.0.0b.run) to a Jetson tx1 board. I’ve successfully installed full Jetson TX1 Developer Kit (64bit) from JetPack 2.2 onto the board. Now, when I download and run ZED_SDK_Linux_JTX1_v1.0.0b.run on the board it seems it progresses without problems but finishes with following lines:

    Setting up unixodbc (2.2.14p2-5ubuntu5) …
    Setting up unixodbc-dev (2.2.14p2-5ubuntu5) …
    Setting up odbcinst (2.2.14p2-5ubuntu5) …
    Processing triggers for libc-bin (2.19-0ubuntu6.9) …
    Install samples (recommended) (Y/N) ?
    Installation path: /usr/local/zed/sample/
    ./linux_install_release.sh: line 262: /usr/local/zed/tools/ZED Explorer: No such file or directory
    ./linux_install_release.sh: line 265: /usr/local/zed/tools/ZED Explorer: No such file or directory
    ZED SDK installation complete !

    If I run /usr/local/zed/tools/ZED Explorer it again says
    -bash: /usr/local/zed/tools/ZED Explorer: No such file or directory

    though the file exists:

    The camera, though plugged in is not recognized either:

    Please help! Tell me what should I do to succeed with ZED SDK installation?

      Hi dd,

      seems that this is an issue of 64bit vs. 32 bit.
      http://askubuntu.com/questions/133389/no-such-file-or-directory-but-the-file-exists

      I have the same problem and I am still searching for a solution.

      The ZED SDK is 32 bit and if you set up the newest Jetson release (JetPack 2.2) then you have a 64bit os which can not run 32 bit apps, like the ZED Explorer etc.

      @Anyone: please, if there is a solution, leave us a message! Thanks!!

      Hi again,

      you have to use Jetson SDK R23.2 together with the ZED SDK.
      L4T R32 Rev.2 can be installed with 32 bit and works out of the box after installing the ZED SDK V1.0.

      BR

        Thank you, I’ve just realized that too when I found that 64bit installation option was added to JetPack only recently. I confirm my ZED SDK v1.0.0b works fine on 32bit version of L4T.

    Hi! What is the absolute minimum object sizes the depth camera can see? I’m looking for a camera that is able to see objects of 0.5cm (any side) on the floor. I will be using a Jetson TX1 board.
