4SightTM for Rail Solutions

Application Overview

The tools required for managing and optimizing the global railway system are highly complex. Rail applications that benefit from the use of LiDAR include: system autonomy, collision avoidance, vegetation and asset inspection (such as track, catenary wires, bridge, and tunnel), trackside mapping, and monitoring passenger flow in stations and movement around maintenance and construction sites. Initially used for mapping applications, the challenge with conventional LiDAR is that it was not made to meet the railway industry’s requirements. For example, conventional LiDAR does not have the long-range detection or classification capabilities needed to alert a high speed or freight train in time to prevent a trackside incident, nor the agility needed to switch from one use case to another in real time. And even for some mapping applications, it doesn’t have the needed resolution.


Autonomy and Collision Avoidance Applications

  • Detect, acquire, and classify actionable information at long range (200-600 meters)
  • High frame rate
  • Agility and ability to focus on specific Regions of Interest (ROIs) with high resolution
  • Reliability and the ability sustain shock and vibration

Mapping and Asset Inspection

  • Focus on high-interest areas (short range)
  • HD scanning to detect small changes or deformations in the assets

Why 4Sight™?

4Sight™’s Unmatched Capabilities

No other sensor system can perform multiple use cases simultaneously (such as system autonomy and mapping) and meet the industry’s range and frame rate requirements. Built on the award-winning iDAR™ platform, AEye’s 4Sight™ boasts the industry’s only solid-state, high-performance, adaptive, intelligent LiDAR which enables the customization and performance of scanning parameters for every use case — from asset inspections and collision avoidance to autonomy. Its software-configurable architecture and ability to process data at the edge of the network results in greater reliability, safety, and performance at longer range and lower cost.

4Sight™ Benefits

  • Detects, acquires, and classifies actionable information at long or short range due to its software-configurable architecture and ability to customize a library of deterministic and/or responsive scan patterns
  • Deploys ultra-high resolution Regions of Interest (ROIs) to detect small objects in the near range
  • Enables train and transit operators to detect small objects at long range (vehicle at 1000m; pedestrian at 400m)
