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 software development.

High-Definition Perception

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.

for Comprehensive On-Road Awareness

Long-Range Perception

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.

Enables All-Weather Perception

IPE: Noise Filter Function

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, thereby enhancing its clarity and enabling all-weather perception across various applications.
