LiDAR Ouster OS0 (Rev 6) ultra wide angle high performance

Ouster OS0 Digital LiDAR: a small device, lots of features

Ouster OS0 is a compact and modular LiDAR that offers many interesting features for roboticists wanting to optimise their navigation system:

• It weighs just 447 g and has a retractable cap
• Ouster’s L2X SoC innovation increases the LiDAR’s signal processing power and data output performance twofold
• The OS0 LiDAR works in all weather conditions, including snow, rain, fog and smoke, and can identify its environment and obstacles even in low visibility, so can integrate sophisticated recognition and surveillance systems
• It has inbuilt protection against dust and moisture ingress and can operate at temperatures of between -40 and 64 °C
• The OS0 LiDAR’s sensors provide a volume of high-quality output data for more efficient and accurate calculation algorithms

In practice, the OS0 LiDAR designed by Ouster blurs the boundaries between video camera and laser capture. Robotic vision is thus increasingly accurate and precise, in all environments.

3 models, 4 configurations

The OS0 digital LiDAR comes in three versions, with 32, 64 or 128 channels. Each model offers a different level of resolution, as well as several vertical angular resolution possibilities.

Each also offers 4 possible configuration options (except the OS0-128 LiDAR), which you can choose according to what you want to do with your Ouster LiDAR:

• “Uniform”, for a uniform scan of the LiDAR’s environment with a vertical field of view of 90°: 45° below the horizontal plane, 45° above
• “Gradient”, for scanning at different levels with a vertical field of view of between 45° and 90°, cut into gradients
• “Below Horizon”, offering a vertical field of view of 45° below the horizon line to scan everything situated below the LiDAR
• “Above Horizon”, offering a vertical field of view of 45° above the horizon line to scan everything situated above the LiDAR

Technical characteristics of the OS0 LiDAR

Gemini, a perception platform compatible with Ouster LiDAR

The Ouster Gemini platform aims to improve safety, intelligent transportation systems or smart cities. It enhances detection and classification performance with more accurate and comprehensive people and vehicle tracking data.

This advanced solution simplifies operations and is more cost-effective, as it requires less sensors.
