Auto-Grade 120° High-Resolution Long-Range Lidar
Product Highlights
The Hesai AT128 is a mass‑production automotive‑grade LiDAR designed as a forward‑facing primary perception sensor for advanced driver assistance systems (ADAS) and autonomous driving. It combines a 120° horizontal field of view with long‑range detection and high resolution to deliver reliable, dense point cloud data for real‑world driving conditions.
Seamless Vehicle Integration
Its compact, sleek design allows for flexible placement (roof, windshield, or grille) while maintaining aerodynamic and aesthetic requirements of production vehicles.
120° Horizontal Field of View
The AT128 provides a wide forward‑viewing angle, covering multiple lanes, intersections, and adjacent traffic with a single sensor—reducing system complexity and integration costs.
High‑Resolution & Long Range
With 128 vertical channels, it generates a dense point cloud that captures fine details of vehicles, pedestrians, and obstacles at long distances. It achieves reliable detection of low‑reflectivity objects (e.g., dark vehicles) beyond 200 meters, enabling early perception for high‑speed driving.
Automotive‑Grade Reliability
Developed and validated according to automotive industry standards, the AT128 is built to withstand harsh environmental conditions (temperature, vibration, moisture) and meets rigorous safety and quality requirements for mass‑produced vehicles.
Class 1 Eye‑Safe
Compliant with Class 1 laser safety standards, ensuring safe operation in all driving scenarios without risk to human eyes.
Key Applications
The AT128 is primarily engineered for automotive applications, but its performance characteristics also make it suitable for other domains requiring high‑resolution forward‑facing perception.
| Application Area | Description |
|---|---|
| ADAS (Advanced Driver Assistance Systems) | Serves as the core perception sensor for L2+ to L3 autonomous driving systems, enabling features such as highway pilot, traffic jam assist, automatic emergency braking (AEB), and adaptive cruise control (ACC). |
| Autonomous Driving | Used in robotaxis, autonomous shuttles, and self‑driving trucks as the primary forward‑facing LiDAR to provide long‑range, high‑resolution perception for urban and highway navigation. |
| Commercial & Fleet Vehicles | Deployed in long‑haul trucks, mining vehicles, and port logistics equipment to enhance safety and enable autonomous operations in mixed‑traffic environments. |
| Smart Infrastructure | Can be applied in toll plazas, highway monitoring, and intersection management to capture detailed traffic flow data with wide coverage and high accuracy. |
| Ground Truth & Research | Provides high‑fidelity sensor data for algorithm training, validation, and autonomous driving research in academic and industrial settings. |
ULTRA-HIGH RESOLUTION
Genuinely 128 channels, evenly distributed to effectively detect cars and pedestrians up to 200 meters away
210m Effective Detection – Ultra-Wide Unstitched FOV of 120°
OVER 1.53 MILLION POINT RATE
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.
