Frequently Asked Questions
What is the HESAI AT128 LiDAR used for?
The HESAI AT128 is an automotive grade long range LiDAR designed for ADAS and autonomous driving applications. It is built as a high resolution main LiDAR sensor for vehicles that need long distance 3D perception, object detection, and real time driving environment awareness.
Why is it suitable for ADAS vehicles?
Suitability for ADAS comes from the combination of 128 channels, 1,536,000 points per second, a 120° x 25.4° field of view, and 210 m detection at 10 percent reflectivity. These specifications help vehicles detect cars, pedestrians, and road objects at long distances.
Is this a long range automotive LiDAR?
Yes. With 210 m ranging capability at 10 percent reflectivity, the sensor is positioned for forward perception in ADAS systems where early object detection is important for highway driving and autonomous mobility.
What makes it different from lower resolution LiDAR sensors?
With 128 channels and a 1200 x 128 pixel resolution, it captures high density point cloud data. Higher resolution helps the vehicle recognize object shape, distance, and position more clearly than lower density sensors.
Why does the 1.53 million points per second rate matter?
That point rate delivers dense real time 3D perception. For ADAS and autonomous driving, higher point density can improve the visibility of vehicles, pedestrians, lane edge objects, and other road users at speed.
What is the field of view of the HESAI AT128?
The field of view is 120° x 25.4°. This wide forward sensing area is designed for vehicle integration, helping cover the road ahead without requiring a stitched multi sensor view for the main front perception zone.
Is it designed for mass production vehicles?
Yes. The sensor is designed for automotive grade, mass produced ADAS programs and has been nominated by multiple ADAS programs from top OEMs.
How compact is it for vehicle integration?
Listed dimensions are 136 mm x 114 mm x 49 mm with a weight of 940 g. This helps vehicle designers integrate a long range LiDAR into front fascia, roofline, or other automotive sensor placements.
Is it reliable for automotive environments?
Yes. Key components meet AEC-Q and other relevant standards, and the design has undergone more than 50 validation tests covering electrical, mechanical, climatic, sealing, material, and EMC requirements.
When should a team choose the HESAI AT128?
Choose the AT128 when you need an automotive grade long range main LiDAR for ADAS, forward object detection, high resolution 3D perception, and production vehicle integration — especially when 210 m range, 128 channels, 1.53 million points per second, and compact automotive packaging are key requirements.
