Real-Time Optical-Wireless Video Surveillance System for High Visual-Fidelity Underwater Monitoring

Real-time, dynamic, and visual monitoring of underwater scenes would become an important research topic with the development wireless optical communication (UWOC), autonomous vehicle, video fusion technologies. To this end, we developed a UWOC-based 2K real-time digital surveillance prototype named AquaF-seer. Using light-emitting diode avalanche photodetector based diffused line-of-sight UWOC system, transmission high resolution 1920 × 1080 pixels is achieved over various channels, i.e., 1.5-m free space channel, pure water channel 1.53-mL/s bubble-induced turbulence, 42.40-mL/s simulated sea coastal ocean channel. Moreover, 46-m 5-m are implemented in outdoor diving pool. It indicates reliability prototype, which first step to realize future human-robot interaction applications.
