Real-world Latency Analysis of Vehicular Visible Light Communication with Multiple LED Transmitters and an Event-Based Camera

Summary

This paper presents an event-camera-based visible light communication (VLC) system for V2X applications. It addresses bandwidth saturation, multi-transmitter reception, and latency characterization. Using a positive-event-only mode, the system suppresses unnecessary events while maintaining distance and wide field of view. It identifies multiple transmitters and demonstrates simultaneous reception from up to three LEDs. Real-world end-to-end latency evaluations show the system meets cooperative perception requirements, making event-camera VLC a feasible complement to RF-based V2X.

Abstract:Event cameras offer high temporal resolution, low latency, and wide dynamic range, making them promising receivers for visible light communication (VLC) in vehicle-to-everything (V2X) applications. This work presents an event-camera-based VLC system addressing three key challenges: bandwidth saturation, multi-transmitter reception, and latency characterization.

We adopt a positive-event-only mode and design a protocol that suppresses event generation while maintaining communication distance and a wide field of view. We also propose a method to identify multiple transmitters and demonstrate simultaneous reception from up to three LEDs. Finally, we evaluate end-to-end latency in real vehicular scenarios and show that the system meets cooperative perception requirements. These results demonstrate that event-camera-based VLC is a feasible complement to existing V2X technologies (e.g., RF).
