The ZED SDK allows you to add depth, motion sensing and spatial AI to your application. Available as a standalone installer, it includes applications, tools and sample projects with source code.
Kael listened with wonder, and as he did, he realized that his own journey had been leading him to this moment. He had been searching for a place where the boundaries between reality and dreams were blurred, where the essence of the world was still pure and untainted.
In a remote valley, hidden between two great mountains, lay a village so serene that it seemed like a dream. The villagers of Azura lived in harmony with nature, their days filled with the sounds of chirping birds and the gentle rustle of leaves. The air was sweet with the scent of blooming flowers, and the soil was rich with the promise of abundance. tamil isaimini dubbed a to z best
Akira and Kael's journey had awakened something deep within the village, a realization that they were not separate from nature, but a part of it. And as they stood before the Oracle, now a symbol of their shared understanding, they knew that their paths had crossed for a reason – to remind the world of the magic that lay just beyond the edge of everyday sight. Kael listened with wonder, and as he did,
As the days passed, the villagers of Azura began to notice a change within themselves. They felt a renewed connection to the land, a sense of belonging that went beyond the physical. The crops began to grow stronger, the rivers ran clearer, and the skies shone brighter. The villagers of Azura lived in harmony with
Akira and Kael met by the ancient tree that stood at the center of the village. The tree, known as the Oracle, was said to hold the memories of Azura and share them with those who approached with a pure heart. As they spoke, Akira realized that Kael was not like other travelers. He had a deep understanding of the world and its workings, and his presence seemed to awaken a part of her that had long been dormant.
Together, Akira and Kael embarked on a journey to explore the mysteries of Azura. They climbed the mountains, crossed the rivers, and ventured into the depths of the forest. With each step, they discovered hidden wonders – a waterfall that sang a melody of crystal clear notes, a meadow where flowers bloomed in every color of the rainbow, and a cave where the walls shimmered with a light that seemed almost divine.

Fixed an OpenGL installation issue on Windows platforms with Python versions 3.12+ when using the script get_python_api.
Fixed a binary compatibility issue between the ZED Python API (pyzed) and numpy that occurred specifically on Windows platforms with Python versions 3.9, 3.10, and 3.11. This fix ensures stable integration and prevents runtime errors related to ABI mismatches in these configurations.
Fixed getVideoSettings(sl::VIDEO_SETTINGS::WHITEBALANCE_AUTO) on ZED-X / ZED-XOne, which was returning an incorrect value at launch (noticeable in ZED Explorer with multiple cameras).
Tools
Added focal length information (in millimeters) in ZED Explorer, within the 'Calibration' window.
Added SVO auto-repair support in ZED Explorer. It will now attempt to auto-repair corrupted SVO files upon opening, similar to ZED Depth Viewer (or SDK).
Fixed ZED Explorer framerate calculator.
Fixed model downloads in ZED Diagnostic tool when GPU is not available.Fixed minor UI issues in ZED Explorer.
Fixed minor UI issues in ZED Media Server.
Fixed video settings control through receiver/host in ZED Media Server. Users can now control virtual ZED-X camera video settings from the receiver side.
Fixed stop signal handling in CLI mode for a proper and clean exit in ZED Media Server.
Added support for different ZED-XOne camera models connected to ZED Media Server (identical resolution is still required).
Added support for multiple JSON configuration files for virtual cameras in CLI mode via the --config option in ZED Media Server.
Wrappers
Improved Python wrapper performance when using multiple cameras in multiple threads.
Improved pip installation behavior in the Python wrapper: now uses --force-reinstall by default to avoid issues with stale pyzed after reinstallation.
Fixed Docker images with OpenGL display; they are now available again.
Fixed minor issues in the C and C# wrappers.
Samples
Improved C++ and Python samples for camera streaming and recording. They are now available and optimized for both single and multi-camera setups.
Bug Fixes
Fixed ZED X auto-recovery function. A regression introduced in 5.0.0 prevented the GMSL camera recovery in case of an interruption.
Fixed a rare crash that could occur when enabling NEURAL depth mode.
Fixed a deadlock in the Object Detection module with the new internal threaded mode introduced in 5.0.0.
Fixed an unclosed file descriptor on Jetson when using SVO H26X input. This could lead to undefined behavior if the Camera class was opened and closed hundreds of times in the same instance processing hardware-decoded SVOs.
Fixed a regression when using multiple GPUs. It now correctly uses the selected device ID.
Fixed multiple bugs in setSVOPosition functions using index or timestamp input. It should now set the expected frame.
Fixed a small memory leak when using Fusion.
Fixed AI model optimization log when using ROS.
Fixed Object Detection crash when passing an invalid or missing custom YOLO-like ONNX file.
Fixed undefined behavior in Object Detection and Body Tracking when processing detector output.
Fixed incorrect retrieveImage output when using specific resolutions. The issue could affect grayscale or low-resolution images.
Fixed isVideoSettingsSupported function with the AEC_AGC_ROI setting that would return invalid results.
Tools
Fixed ZEDfu NEURAL depth mode optimization.
Improved Depth Viewer camera open when switching between camera models.
Improved ZED Explorer firmware update GUI on ZED X for clarity.
Samples
Added support for YOLOv11, YOLOv12, and more when using a custom YOLO-like ONNX model. Check out the dedicated documentation page.
Updated C++ Spatial Mapping sample.
Updated C++ Positional Tracking sample.
Camera Drivers
Added support for Jetson RT Kernel for ZED X camera with dedicated drivers.
Deprecation
Using retrieveObjects and retrieveBodies with runtime parameters is now deprecated. Setting runtime parameters should now be done using the dedicated setters.
Camera::retrieveImage
Camera::retrieveMeasure
Added GPU-optimized functions, blobFromImage, and blobFromImages, for converting images to Deep Learning model tensor inputs.
Added utility functions, Mat::convertColor, for common color conversions, such as swapping red and blue channels and removing the alpha channel.
Added support for Custom OpenCV Calibrations with sl::CameraOne
Updated default Image framerate to 30Fps, it provides the best performance compromise
Updated IMU data rate for ZED X camera to 200Hz instead of 400Hz, it improves stability and performance, especially for multi-camera setups
Updates the default InitParameters::depth_stabilization value set to 30, it provides a more stable depth with minimal motion artifacts
Renamed Camera::retrieveObjects to Camera::retrieveCustomObjects for custom object detection. The default behavior remains unaffected, but the new method is required when using CustomObjectDetectionRuntimeParameters.
Added new parameters to the CustomObjectDetectionProperties struct:
(min|max)_box_(width|height)_meters, to give control to maximum 3D objects dimensions
native_mapped_class, to allow remapping a custom label to the SDK’s internal SUBCLASS and profit the internal tuning
object_acceleration_preset and max_allowed_acceleration to have better control of the tracked objects' maximum acceleration
Bug Fixes
Fixed a potential deadlock in Positional Tracking GEN_2
Fixed the function to retrieve unified point clouds from multiple camera setup within the Fusion API
Fixed a random issue leading to NAN values in IMU orientation.
Fixed the function resetPositionalTracking when using Positional Tracking GEN_2
Fixed a random issue leading to NAN position in Object Tracking
Fixed random memory leak in Fusion when playing back SVO files
Fixed ZED-One UHD 4K SVO recording/playback

Platforms
Removed support for legacy Jetpacks 4.6, 5.0, and 5.1 (L4T 32.7, 35.1, and 35.2 respectively)
Added support for TensorRT 10, this version introduced Blackwell GPU support (with CUDA 12.8) but dropped Pascal GPU support. For GTX 10X0 series GPU, TensorRT 8 installers should be used.
