ZED Tools 5.2

What’s New

ZED Studio gains 2D depth map views and depth parameter controls for cameras, SVOs and streams, a resizable left panel and faster multi-camera rendering. ZED Explorer displays the physical GMSL port of each camera. ZED SDK 5.2.1 fixes the command-line options of ZED Explorer and ZED Depth Viewer and makes the NEURAL depth model optimization in ZED Depth Viewer more robust, and ZED SDK 5.2.2 introduces the beta ZED Sensor Placer tool for multi-sensor extrinsic calibration.

5.2.3

Released: Mar 26, 2026

ZED Depth Viewer

• Fixed the UI refresh rate when pausing SVO playback.

5.2.2

Released: Mar 13, 2026

ZED Explorer

• Fixed wrong FPS reported on Windows.

ZED Depth Viewer

• Fixed the point cloud density.

ZED Diagnostic

• Fixed a crash when testing the camera on Windows.

ZED Sensor Placer

• Added the new beta ZED Sensor Placer tool for multi-sensor extrinsic calibration using manual placement. It supports both cameras and lidars.

5.2.1

Released: Mar 2, 2026

ZED Explorer

• Fixed the “No current context available” error on Jetson platforms.
• Fixed the --resolution, --frequency, --input and --serial_number command-line options being ignored when selecting a camera for recording, streaming, firmware update, or GUI launch.
• Changed the default resolution from hardcoded values to AUTO, which resolves to the best default per camera model (e.g. HD720 for USB cameras, HD1200 for GMSL), consistent with the sl::InitParameters defaults. Applies to both the CLI and the GUI.
• Fixed “FRAMERATE: N/A” being reported for USB cameras.

ZED Studio

• Completely removed the depth map field from the Settings Panel for monocular cameras.
• Added the option to enable or disable the depth view directly from the Depth Panel by changing the Depth mode.
• Fixed a UI issue when opening SVO files.
• Depth settings are now applied to SVO and stream inputs.

ZED Depth Viewer

• Fixed the --resolution and --frequency command-line options being parsed but never applied.
• Fixed a crash (SIGSEGV) occurring during or after NEURAL depth model optimization. Optimization now runs in an isolated subprocess, preventing TensorRT-related crashes across camera open and close cycles.
• Fixed the optimization dialog displaying a generic “NEURAL” label instead of the selected mode (NEURAL, NEURAL PLUS or NEURAL LIGHT).
• Fixed the depth view freezing while the optimization confirmation dialog was displayed.
• Fixed declining the optimization dialog switching to a different depth mode instead of keeping the current one.

ZED Sensor Viewer

• Fixed the sensor data frequency not being displayed when using an SVO input.

ZEDfu

• POSITIONAL_TRACKING_MODE::GEN_3 is now the default positional tracking mode, consistent with the ZED SDK.

ZED Diagnostic

• Fixed a crash (SIGSEGV) during the camera resolution tearing test. It was systematic on Linux and intermittent on Windows.

5.2.0

Released: Feb 10, 2026

ZED Explorer

• Added the display of the physical GMSL ports in both the CLI and the GUI.
• Updated the ZED Mini MCU firmware reference to v517.
• Fixed a crash occurring in the Windows settings.
• Fixed a UI issue where the MCU firmware update could stop ZED Explorer from working.

ZED Studio

• Added the -l flag to list the serial number, ID and GMSL port of the connected cameras.
• Added 2D depth map views for cameras, SVOs and streams, and depth parameter controls. The 2D depth map can only be toggled for stereo cameras.
• Improved rendering performance for multi-camera setups.
• Made the left panel resizable; it can also be fully collapsed.
• Fixed the style of the “Connect to Stream” window on Windows.

ZED Sensor Viewer

• Fixed IMU retrieval errors during frame corruption.

ZEDfu

• Fixed tracking modes being ignored after a reset.

ZED360

• Console logs are now visible in the Windows terminal.
