Introduction
As demand grows for large-area, high-precision, multi-point interaction, traditional single-sensor systems can no longer meet the needs of modern interactive environments. Multi-LiDAR cascading—the integration of multiple LiDAR devices or chips—offers a powerful solution by expanding detection range, enhancing resolution, and supporting multiple users and touchpoints.
In this article, we explore real-world application scenarios where multi-LiDAR cascading plays a critical role in enabling seamless, contactless interaction and detection.
Application Scenarios for Multi-LiDAR Cascading
| Scenario | Description |
|---|---|
| Large Exhibition Halls & Museums | Cascaded LiDAR units cover wide exhibition zones, enabling non-contact, multi-user interaction for immersive digital exhibits. |
| Outdoor Events & Public Spaces | Multiple LiDARs form a unified sensing network, supporting long-range, high-precision interaction—even under strong light or environmental noise. |
| Multi-Screen Video Walls & Projections | Enables seamless multi-touch gestures across large spliced LCD panels or interactive projection walls. |
| Autonomous Driving (4D Imaging) | Cascading LiDAR chips enhances angular resolution and channel density—ideal for 4D mmWave LiDAR systems in ADAS and autonomous vehicles. |
| Industrial Automation & Robotics | Improves spatial awareness and target recognition for precise object tracking, navigation, and action response in manufacturing environments. |
| Security Monitoring & People Tracking | Enables real-time, multi-target tracking and behavior analysis over large surveillance zones. |
Real-World Use Cases & Technical Background
1. 4D Imaging LiDAR in Autonomous Vehicles
By cascading multiple LiDAR chips (e.g., 4-chip cascade), automotive systems gain a higher number of virtual channels and better angular resolution. This allows real-time detection of multiple moving objects, critical for autonomous driving and advanced driver-assistance systems (ADAS).
2. Multi-LiDAR Synchronization in Interactive Exhibits
In large-scale digital installations, multiple POE LiDAR units are cascaded to create a unified gesture interaction space. This ensures consistent, multi-point, touchless user interaction across extended areas, regardless of display size or user count.
3. Factory-Level Multi-Target Detection
In smart factories, LiDAR cascading enhances detection precision for robotic arms, AGVs, and safety systems, enabling real-time decision-making based on accurate spatial data in dynamic environments.
