Ouster Sensor SDK
The Ouster Sensor SDK provides developers interfaces for interacting with sensor hardware and recorded sensor data suitable for prototyping, evaluation, and other non-safety-critical applications in Python and C++. Example and reference code is provided for common operations on sensor data in both languages. The SDK includes APIs for:
Querying and setting sensor configuration
Recording and reading data in pcap format
Reading and buffering sensor UDP data streams reliably
Conversion of raw data to range/signal/near_ir/reflectivity images (destaggering)
Efficient projection of range measurements to Cartesian (x, y, z) coordinates
Visualization of multi-beam flash lidar data
Additionally, in Python, the SDK also provides:
Frame-based access to lidar data as numpy datatypes
A responsive visualizer utility for pcap and sensor
Compatibility with FW
The Ouster SDK currently provides backwards compatibility with any FW 2.0 and later for all releases. Older SDK versions are not, however, generally forward-compatible with later FW releases, e.g., the SDK version 20210608 (ouster-sdk 0.2.0) is not compatible with FW 3.0.
Note
Please note that compatibility does not indicate that upgrading between SDK versions can happen seamlessly. For information on breaking changes between releases, please the Changelog.

Status and Contact Info
The Ouster SDK is currently provided as an early pre-1.0 preview. The APIs are subject to change in every release.
For questions about using your Ouster hardware, you may find it useful to reference the Ouster sensor documentation and/or contact Ouster support. For issues specific to the SDK please use the GitHub issue tracker. Announcements for the Ouster SDK are posted in the Ouster Github announcements
