Calibration Free 360° Unstitched FOV

A single OT128 lidar can cover a vehicle’s entire field of view without stitching, eliminating the need for multiple calibration steps which can significantly accelerate algorithm development.

Ultra-High Resolution, Powering Seamless Intelligent Driving

With a finest angular resolution of 0.1° (H) x 0.125° (V), the OT128 can accurately perceive objects large and small at a distance of 200 meters away,
providing powerful perception data for autonomous driving systems.

Long-Range Perception for Comprehensive On-Road Awareness

Under 100 klux strong ambient light, OT128 has a ranging capability of 200 m at 10% reflectivity (230 m maximum),
clearly detecting objects in real time and capturing every detail of its surrounding road conditions.

IPE: Noise Filter Function Enables All-Weather Perception

Leveraging Hesai’s proprietary Intelligent Point Cloud Engine (IPE), the OT128 is capable of detecting rain, fog, exhaust fumes, and water splashes on the road. It performs real-time marking of these phenomena at a pixel level, effectively filtering out environmental noise. This capability will significantly mitigate the impact of rain and fog on lidar performance, there by enhancing its clarity and enabling all-weather perception across various applications.
