Release Notes

What's New
Jun 15, 2018
ZED SDK 2.4 introduces a major firmware update for ZED and ZED Mini, improving USB connectivity on Windows 10 and bringing multi-camera support to Windows and Linux.
The release also introduces plane detection for a simplified understanding of the environment, improved positional tracking and Jetson support, as well as various fixes and improvements to the ZED API, tools and plugins. Read More.
2.4.1

Legacy

For older releases and changelog, see the ZED SDK release archive.

SDK

Video

Improved asynchronous recording of SVO with up to 50% bandwidth. Read More.
Reduced latency on Linux platforms. The image buffer is now filled asynchronously instead of waiting for a grab() call.
Fixed a recording issue leading to IMU data not being saved in SVO file.

Depth

Improved depth estimation and stability for homogeneous surfaces in FILL sensing mode.
Improved depth edges sharpness in FILL sensing mode.

Tracking

Improved tracking robustness when objects are moving close to the camera (like user hands in AR).
Updated visual odometry behavior. Tracking will not jump anymore when spatial memory is not enabled.
Updated spatial memory behavior. Relocalization is more robust and loops are done more frequently to improve localization. Read More.

Plane Detection

Fixed an issue where plane detection could detect the ceiling as a floor plane when using a ZED (which doesn't have an IMU).

Samples

Introduced a zed-opencv-native sample for stereo image capture without the SDK.

Tools

Added a message in ZED Explorer to let you know when a new SDK version and firmware is available.
Updated ZED World to UE 4.19 and optimized performance which has been greatly improved.
Updated ZED World to fix image stutter in Oculus Rift.

Jetson

Improved depth and tracking performance on Jetson thanks to internal optimizations and script update. Read More.

2.4.0 SDK

API

Updated the video capture pipeline to improve USB 3.0 capture on Windows 10 and make it significantly more reliable. All recent laptops should now be able to run the ZED without dropping or skipping frames.
Added Camera::findFloorPlane function for floor detection and improved tracking initialization.
Added Camera::findPlaneAtHit function that returns the best matching plane at a selected pixel position in the image.
Added Plane object to store information about a detected plane, such as its center, normal, bounds, etc.
Updated open() function to allow SDK, tools and plugins to open a camera 0.5s faster.
Reduced SVO compression ratio in Lossy mode to improve image quality.
Deprecated function Camera::setFPS.
Fixed an issue that could allow CameraInformation::camera_imu_transform to be empty.

Depth

Improved depth edges and details in PERFORMANCE and ULTRA modes.
Confidence maps have been updated for better usability.
Updated confidence threshold to 97% in Depth Viewer.
Removed saturated bright areas from depth maps in all modes.
Fixed depth stabilization bug that would disable the stabilizer if tracking state switched to SEARCH.
Fixed depth stability bug on MEDIUM and QUALITY depth modes in STANDARD sensing.

Tracking

Fixed issue with IMU that would increase drift when using visual-inertial positional tracking.
Fixed a potential crash when restarting positional tracking.
Fixed memory allocation bug that would not completely free memory when enabling, disabling or resetting tracking.

SVO

Fixed an issue where the initial tracking position would be incorrect when playing back an SVO taken with a ZED Mini.
Fixed an issue preventing tracking from being enabled if self-calibration was disabled for an SVO recorded with a ZED Mini.
Fixed an issue where some raw IMU data could be corrupted when recording an SVO in Lossy mode.
Fixed depth stabilization bug that would produce incorrect depth data when pausing an SVO.

Samples

Introduced a multi-camera sample to show how to capture data from multiple connected devices on Windows and Linux.
Introduced a new plane detection sample to display planes detected by findPlaneAtHit and findFloorPlane functions.
Introduced an OpenGL example code to show how to display camera feed with OpenGL.
Updated positional tracking example code to show how to get IMU data from a ZED Mini.
Updated MATLAB plugin with getIMUData function, giving access to the ZED Mini IMU values.

Documentation

Updated Mesh API reference documentation to describe how textures are linked to vertices.
Updated Unity Spatial Mapping section to add missing steps in the tutorial.

Plugins

ROS - Added dynamic adjustment of gain and exposure settings in ROS wrapper (Thanks to GitHub user @fujimo-t).
Unity - Major update of the plugin. See changes here.
Unity - Released plugin source code on GitHub. Contributions are encouraged!

Platforms

Updated to JetPack 3.2 for Jetson TX1 and TX2.
Updated Jetson installer to enable MAX-N performance mode by default.
Added Ubuntu installer compiled with CUDA 9 for better TensorFlow compatibility.
