Release Notes

• What's New

  Aug 8, 2018

  The ZED SDK 2.5 release includes support for CUDA 9.2, along with a major update of ROS, Unreal and Unity plugins.

• 2.5.1

  SDK

  General

  • Fixed segmentation fault when using the ZED in USB2.0 on Ubuntu.
  • Fixed memory leak on getDeviceList().
  • Fixed a bug that leads to a wrong camera detection in getDeviceList() when this function was called multiple times.
  • Fixed wrong timestamp in IMUData when getIMUData(TIME_REFERENCE_CURRENT) was called. Now, you can use the timestamp to check if the values are new (timestamp will be different, otherwise they will be the same).
  • Fixed a freeze which can occurs when calling resetTracking() while grab() is running.
  • Fixed the return value of getPosition() just after a call to resetTracking().
  • Fixed an issue in the Linux installer in silent mode where the script could ask for a user input.
  • Deprecate SpatialMappingParameters::set(mapping_range). Now appropriate range is derived from selected MAPPING_RESOLUTION when calling enableSpatialMapping() if SpatialMappingParameters::range_meter is not defined.
  • Add function getRecommendedRange(mapping_resolution, &camera) to set SpatialMappingParameters::range_meter directly to the recommanded value.

  Dependency

  • Removed libusb-0.1 dependency to fix an issue when using the ZED for an extended period of time.

  Docs

  • Updated API documentation. More details and code samples are now available.

• 2.5.0

  SDK

  General

  • Added support for CUDA 9.2.
  • Fixed a random freeze in Camera::close() on Linux Ubuntu when the camera was unplugged during a frame grab.
  • Added new coordinate system RIGHT_HANDED_Z_UP_X_FWD for use in ROS.

  Depth

  • Moved depth computation to a non-default stream to achieve concurrency with external GPU operations and improve performance.
  • Fixed an issue leading to NaN values in depth FILL when setting the confidence threshold at 100.

  Plane Detection

  • Fixed bug that reported wrong planes when the UNIT parameter was not set in METERS.

  Plugins

  ROS

  • Updated wrapper support to ZED SDK 2.5.
  • Refactored wrapper code for clarity.
  • Added support for spatial memory and pose smoothing.
  • Added parameter for changing initial tracking position.
  • Added dynamic resolution setting for image/measures to allow testing different accuracy and performance optimizations.
  • Updated "package.xml" to "Format 2". Thanks to rbonghi.
  • Updated publishing rules to stream Odometry when subscribing to point cloud topics. Thanks to ArkadiuszNiemiec.
  • Added launch example to run wrapper nodelet in a standalone nodelet manager. Thanks to Russ76.
  • Added publisher for internal IMU data. Thanks to tonftybj.
  • Added publisher for disparity image. Thanks to fujimo-t.
  • Fixed minor bugs.

  Unity

  • Major update of the plugin, which now includes several new samples showing how to use advanced interactions between the real and virtual world. See all changes here.

  Unreal

  • Updated Mixed Reality engine to 4.19.1 version.
  • Improved overal engine performance
  • Improved Vive support.
  • Added option in BP_Initializer for selecting the Pawn tracking mode: ZED, HMD or mixed tracking.
  • Added SRemap experimental rendering option which improves visual comfort in AR passthrough.
  • Moved BP_ZedCamera blueprint class to C++ only.
  • Fixed a bug making the Editor randomly crash when closing the game preview.
  • Fixed a bug saying "wrong reference frame" when starting game preview.
