ouster-sdk

What it is and what it does

Ouster SDK is a production-stable Python library for interacting with Ouster multi-beam flash lidar sensors. It handles sensor configuration, UDP data stream acquisition, recording to pcap and Open Sensor Format (OSF), and conversion of raw measurements into range/signal/reflectivity images and Cartesian point clouds. The SDK also includes visualization, mapping, pose optimization, localization, and zone monitoring tools.

The package is designed for prototyping, evaluation, and non-safety-critical applications. It provides frame-based numpy access to lidar data, a responsive pcap/sensor visualizer, and efficient projection routines. Installation is straightforward via pre-built wheels on Python 3.8 through 3.13 across Linux, macOS, and Windows; source builds are also supported on Ubuntu, Debian, and macOS.

Use it for:

• Record and playback lidar sensor data in pcap or OSF format for offline analysis and algorithm development.
• Query and configure Ouster sensor parameters programmatically via SDK interfaces.
• Convert raw lidar measurements to Cartesian point clouds for 3D scene reconstruction and visualization.
• Build robotics applications using real-time UDP lidar streams with reliable buffering.
• Visualize multi-beam flash lidar data with the built-in responsive visualizer for debugging.
• Integrate lidar data into mapping, localization, and zone monitoring workflows.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Ouster SDK provides Python interfaces to configure, record, and process data from Ouster lidar sensors, including point cloud projection, visualization, and multi-beam flash lidar data handling.

Yes. Ouster SDK is actively maintained (version 1.0.1 released 2026-08-13), has no known vulnerabilities, and offers production-stable interfaces for Ouster sensor integration. Medium install friction is acceptable given comprehensive pre-built wheel coverage and broad Python version support. Install if you work with Ouster lidar hardware or need to process Ouster recordings; skip if you use a different lidar vendor.

Install

ouster-sdk on PyPI

pip install ouster-sdk

uv add ouster-sdk

poetry add ouster-sdk

Installing ouster-sdk

Before you install

Medium install friction: pre-built wheels available for Python 3.10, 3.11, 3.12, 3.13 on Linux (x86_64, ARM64), macOS 14 (x86_64, ARM64), and Windows; 17 runtime dependencies including numpy, Pillow, and flask add some weight but are widely available.

License in practice

Dual-licensed under BSD-3-Clause (source code) and Ouster-Freeware-EULA (pre-built binaries). Permissive for most use; review the freeware EULA terms for proprietary Ouster components bundled in wheels.

Quickstart

pip install ouster-sdk

import ouster.sdk.client as client

sensor = client.Sensor.connect()
data = sensor.get_metadata()

Requires Python 3.8 or later; sensor connection requires network access to an Ouster device or a pcap/OSF recording file.

Verify before relying

• Whether all 17 runtime dependencies are required for basic use or only for specific features like visualization or ROS integration.
• Performance characteristics and typical latency for UDP stream buffering and point cloud projection at sensor frame rates.
• Network configuration and authentication requirements for sensor connection.
