Motion-Aware Optical Camera Communication with Event Cameras
This addresses performance issues in data streaming for smart mobile devices, representing a novel method rather than incremental improvement.
The paper tackles the problem of dynamic factors like screen refreshing and camera motion degrading Optical Camera Communication systems by introducing a novel system using event cameras, achieving up to 114 Kbps throughput in static conditions and 1 cm localization accuracy with 1% bit error rate under motion.
As the ubiquity of smart mobile devices continues to rise, Optical Camera Communication systems have gained more attention as a solution for efficient and private data streaming. This system utilizes optical cameras to receive data from digital screens via visible light. Despite their promise, most of them are hindered by dynamic factors such as screen refreshing and rapid camera motion. CMOS cameras, often serving as the receivers, suffer from limited frame rates and motion-induced image blur, which degrade overall performance. To address these challenges, this paper unveils a novel system that utilizes event cameras. We introduce a dynamic visual marker and design event-based tracking algorithms to achieve fast localization and data streaming. Remarkably, the event camera's unique capabilities mitigate issues related to screen refresh rates and camera motion, enabling a high throughput of up to 114 Kbps in static conditions, and a 1 cm localization accuracy with 1% bit error rate under various camera motions.
