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.
Blackwell GPUs must use TensorRT 10 and CUDA 12
ZED SDK 5.0 delivers 5× faster depth sensing, 300% lower compute load on Jetson, and improved depth accuracy in challenging environments. It introduces new depth modes powered by TERRA AI, offering options for higher accuracy and faster depth processing to suit different applications. The update also debuts Magellan™, a vision-based localization system providing centimeter-level positioning indoors and outdoors. Additionally, the capture pipeline architecture has been optimized to improve stability, reduce dropped frames, and lower video latency to under 60ms, delivering one of the lowest latencies in the industry.
For older releases and changelog, see the ZED SDK release archive.

Previously, some samples only recognized the .svo extension.ERROR_CODE), stopping only on ERROR-level. This improves robustness when occasional issues, like image degradation detected by enable_image_validity_check, occur but the ZED SDK remains functional.get_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.Jul 1, 2025

Please note that 5.0.1 and 5.0.0 are not binary compatible. The Python API package will only work with 5.0.1. You should compile it from source if needed to run with 5.0.0.
retrieveObjects and retrieveBodies functions without runtime parameters have been added as well.ENU2Geo and Geo2ENU in sl::Fusion, making it easy to compute latitude-longitude coordinates of a 3D point.

The older computer vision modes are now deprecated, the previous NEURAL models can still be accessed for retro compatibility.sl::Camera::read() function that optionally separates the grab() function into two distinct operations: acquiring new images and processing data. This function does not affect existing applications using grab(), it will detect if the read() function was called or not.
