What's New


ZED SDK 2.8 introduces streaming ZED video feed across a network, turning ZED cameras into IP cameras. It also adds support for point-based spatial mapping, simpler Jetson installation process and major wrapper/plugin updates. Read more.


  • Updated automatic port assignment for the streaming receiver. Previously, the port was randomly choosen in a list of available ports.

    Now the port assigned is either the same port number defined in InitParameters.input.setFromStream(ip,port) or the closest available port number if the port defined is not available.

    This allows to know explicitely the internal port that will be used by the streaming receiver, which is useful in applications where the receiving port number must be defined explicitely (Docker containers for example). See InitParameters.input.setFromStream() API documentation for more information.

  • Added support for CUDA 10.2 (Windows, Ubuntu 16, Ubuntu 18)
  • Added support for JetPack 4.3 (Nvidia Jetson)


  • Fixed a memory leak in Streaming module on Jetson that continuously increased memory until the camera was closed.
  • Improved IMU timestamp accuracy. Timestamp is based on epoch time and IMU clock drift is now compensated. Note that getIMUData(TIME_REFERENCE_IMAGE).timestamp and getTimestamp(TIME_REFERENCE_IMAGE) can now be slightly different since they are not based on the same computation, however the difference will be less than the time of a frame.
  • Fixed a wrong translation scale that was applied in getCameraInformation().camera_imu_transform. Translation was given in meters when the selected unit was in millimeters.
  • Fixed ZED Explorer which was still creating a UI interface when used in command line. Command line options are now available even if no screen is connected to the host PC/Jetson.
  • Fixed Jetson clock script so that it correctly enables maximum performance (nvpmodel -m 0) with the new JetPack 4.2.


  • Fixed multiple camera detection on Ubuntu 18.
  • Fixed getCameraSettingsValue() when using network streaming input. It was not fully supported on previous versions.
  • Fixed random freeze on Windows when using network streaming input.
  • Fixed retrieveImage() for Side by Side View mode that would lead to an empty image.
  • Fixed error code that returned SUCCESS when retrieveImage() or retrieveMeasure() was used with a resolution higher than the camera resolution. Functions will now return ERROR_CODE_INVALID_RESOLUTION.
  • Fixed a bug in LOSSLESS compression on Linux when using ZED Mini cameras. IMU metadata was not reported in the SVO file, leading to wrong tracking states.
  • Fixed metadata synchronization issue where IMU and image data could be out of sync in H264 (AVCHD) and H265 (HEVC) SVO files recorded on Desktop platforms.
  • Fixed support of Visual Studio 2019 for Samples that required GLEW library.
  • Improved mouse control in Positional Tracking sample.
  • Fixed SVO playback controls in ZED Explorer. Previously, the "+/-" button could jump one frame each time it was clicked.
  • Fixed SVO conversion to H264 (AVCHD) and H265 (HEVC) in ZED SVO Editor tool.
  • Improved zoom in/out control in Depth Viewer.
  • Added support for building applications with Unity and ZED on Linux. See zed-unity repository for more information.
  • Fixed issue when using multiple cameras that could lead to a crash if both cameras shared the same CAMERA_ID.
  • Fixed minor issues in the plugin. See zed-unity release notes for more details.


  • Added static sl_svo library on Linux. All ZED SDK libraries are now available as static libraries.
  • Fixed SVO playback speed in ZED Explorer. SVO are now played at their capture speed.
  • Applied multiple minor UI updates in ZED Explorer.
  • Fixed an issue preventing the tools to be launched with a double click on Ubuntu 18.
  • Fixed unrectified image orientation in Flip mode.
  • Fixed a potential issue leading to file corruption when multiple programs accessed the camera calibration file at the same time.
Positional Tracking
  • Updated IMU output to remove gyroscope bias correction from raw data. This will improve SLAM algorithms that include online bias estimation and use the IMU raw data.
  • Fixed enable_imu_fusion function. When set to false, it now effectively disables IMU use for visual odometry estimation.
Spatial Mapping
  • Fixed a memory detection issue preventing the mapping to start when <2GB of RAM was available.
  • Fixed a potential issue when reading the last frame of an SVO file.
  • Added support for ~ character in SVO paths on Linux.
  • Added ArUco Marker detection sample showing how to relocalize the camera during tracking.
  • Updated OpenCV-related samples for compatibility with OpenCV 4.
  • Fixed installation of the SVO recording sample.


Positional Tracking
  • Fixed IMU bias correction that could lead to slow movement not being correctly tracked.
  • Fixed automatic low recording bitrate when target FPS is not reached.
  • Fixed ZED Explorer image stall when taking a screenshot.
  • Removed debug message in ZED Explorer console.


New Features

Streaming over IP network
  • ZED SDK 2.8 introduces a brand new streaming feature. Users can now connect as many ZED cameras as needed directly to a network and conveniently access the video feeds simultaneously, on multiple devices and applications. Get Started.
  • Also, Ethernet cabling greatly extends the distance allowed between the ZED camera and the host device making installation and placement of ZED cameras more flexible and scalable.
  • Introducing a brand new ROS 2 wrapper for the ZED SDK, taking advantage of all the new features and optimization of the new ROS 2 version.


  • Added Streaming capabilities. The ZED SDK can now stream data from local cameras over the network, for multiple remote computers running the SDK to use as input.
  • Added support for scanning into point clouds using Spatial Mapping.
  • In collaboration with NVIDIA, solved an issue on Jetson preventing the ZED Mini from being detected after reboot. Fix is available in Jetpack 4.2 and will be applied to older versions.
  • Fixed an issue on Jetson TX2 leading to incorrect floor plane detection with the ZED Mini.
  • Fixed image timestamping issue that could lead to offsets when using getTimestamp(TIME_REFERENCE_IMAGE).
  • Added input.setFromStream() function in InitParameters to open a streaming camera.
  • Added enableStreaming() and disableStreaming() functions to start and stop a stream from a camera.
  • Added StreamingParameters structure to setup custom bitrate, port and codec of a camera stream.
