¿µ¹®³»¿ë¿ä¾à Generally, optical camera communication transmits data when both the light source and the camera are fixed. However, supporting camera mobility requires improved BER performance by eliminating noise and mitigating interference problems. In general, convolutional neural networks are introduced for accurate detection and recognition of light-emitting diode patterns in long distance communication and bad weather conditions. This standard proposes a long-range optical camera communication system using a convolutional neural network technique that can assist higher mobility with accurate detection of individual LED from LED array, or camera movement.
