Description

The Hesai Technology QT128 leverages advanced multi-channel laser scanning technology to generate a dense, real-time 3D point cloud of its surroundings. Its 128-channel architecture and 0.4° angular resolution enable high-fidelity perception, critical for distinguishing fine details and small obstacles in complex operational environments such as urban streets, logistics hubs, and industrial facilities.

Built to automotive and industrial reliability standards, the sensor features robust environmental sealing (IP6K7 & IP6K9K) and is designed for thermal stability and shock resistance. This ensures consistent performance under vibration, wide temperature swings, and exposure to dust and water ingress, making it suitable for integration into autonomous vehicle perception stacks, mobile robotics navigation systems, and smart city infrastructure monitoring platforms.

Key Features

  • Automotive-Grade Performance: 128-channel design delivers high-resolution, 360° short-range environmental perception for safety-critical applications.
  • Ultra-Wide Vertical FOV: 105° vertical field of view provides exceptional overhead and ground-level coverage, reducing blind spots.
  • High-Speed Data Acquisition: Generates 1.15 million points per second for real-time, high-density 3D mapping and object classification.
  • Precision Angular Resolution: 0.4° (H) x 0.4° (V) resolution ensures fine detail capture for accurate obstacle detection and localization.
  • Optimized for Low Reflectivity: Reliably detects objects with as low as 10% reflectivity at a range of up to 20 meters.
  • Extreme Environment Rated: IP6K7 (dust-tight, protected against high-pressure water jets) and IP6K9K (protected against high-temperature, high-pressure water jets) certifications.
  • Compact Form Factor: Measures Φ 87 x H 83.9 mm with a lightweight design for easy integration into vehicle roofs, robot frames, and fixed installations.
  • Robust Mechanical Design: Engineered for shock, vibration, and thermal stability to meet the demands of mobile and outdoor use.

Applications

  • Autonomous Vehicle Perception: 360° short-range object detection and free-space mapping for urban autonomous driving and last-mile delivery robots.
  • Mobile Robotics Navigation: High-fidelity environment modeling for AGVs (Automated Guided Vehicles), AMRs (Autonomous Mobile Robots), and inspection robots in warehouses and factories.
  • Smart Infrastructure Monitoring: Traffic flow analysis, pedestrian detection, and obstacle monitoring for intelligent intersections and public space management.
  • Logistics and Port Automation: Precise localization and obstacle avoidance for automated container handlers and yard tractors.
  • Construction and Mining Site Mapping: Real-time 3D scanning for terrain mapping, volume calculation, and vehicle guidance in dynamic, unstructured environments.

Frequently Asked Questions

What is the effective detection range of the Hesai Technology QT128 LiDAR?

The QT128 is optimized for short-range perception, with a maximum detection distance of 20 meters for objects with a reflectivity of 10%. This range is ideal for detailed near-field environment mapping and obstacle detection in applications like low-speed autonomy and robot navigation.

What do the IP6K7 and IP6K9K ratings mean for this sensor?

IP6K7 indicates complete protection against dust ingress and protection against the effects of immersion in water under high pressure (1 meter depth for 30 minutes). IP6K9K adds protection against high-pressure, high-temperature water jets (80°C) from any direction. These ratings certify the sensor's suitability for harsh outdoor and automotive environments.

What type of data interface does the QT128 use?

While the specific interface is not detailed in the provided specs, automotive-grade LiDARs like the QT128 typically provide high-speed digital interfaces such as Gigabit Ethernet (often using protocols like UDP for point cloud data) alongside secondary connections for power and control. It is designed for integration into larger perception systems.

Is this sensor suitable for mobile robotics applications?

Yes, the QT128 is an excellent choice for advanced mobile robotics. Its compact size, lightweight design, ultra-wide 105° vertical FOV, and high point density provide robots with comprehensive situational awareness for navigation, object interaction, and safety in dynamic indoor and outdoor settings.

How does the angular resolution affect the sensor's performance?

The 0.4° horizontal and vertical angular resolution defines the spacing between individual laser points in the point cloud. This fine resolution allows the QT128 to detect smaller objects and capture more detailed contours of the environment, which is critical for accurate object classification, lane marking detection, and precise localization.
