LiDAR Ouster OS2 (Rev 6) long range high performance

OS2: Ouster’s longest-range OS LiDAR

The OS2 digital laser LiDAR is another member of the new family of LiDARs designed by Ouster. This new range of robotics accessories is designed to meet all embedded robotics requirements:

• Compact, lightweight, highly durable devices offering high water and dust ingress protection
• An innovative range on account of its L2X SoC, which increases the data processing capacity and doubles the output flow
• Image quality is increasingly similar to that of a video camera, with ultra-precise reproduction of both fixed and moving obstacles
• The OS2 LiDAR can scan its environment in any level of visibility and operates in all weather conditions, even snow and thick fog

OS2 has a detection range of 240 metres and a vertical field of view. It comes in three versions: 32, 64 or 128 channels, each with its own technical characteristics (see technical specifications).

Four possible configurations to adapt your LiDAR’s vision

The OS2-32 and OS2-64 models each offer four configuration options:

• “Uniform”, for a balanced vertical scan 11.25° either side of the horizon (22.5° in total)
• “Gradient”, which divides the vertical field of view into several gradients to adapt the device’s detection capabilities to your specific needs
• “Below Horizon”, which directs the scanning beam downwards, with a vertical field of view of 11.25° below the horizon line
• “Above Horizon”, which directs the scanning beam upwards, with a vertical field of view of 11.25° above the horizon line

Please note that the OS2-128 version does not offer these configuration options.

The possibilities offered by the Ouster OS2 LiDAR make it a great choice for robotics projects in a wide range of fields: autonomous navigation, exploration and surveillance of risky areas, remote monitoring, robotic vision, service robotics, etc.

Technical characteristics of the OS2 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.
